5 | ##插件核心思想 6 | 7 | ###1.aapt的改造 8 | 分别对不同的插件项目分配不同的packageId，然后对各个插件的资源进行编译，生成R文件，然后与宿主项目的R文件进行id的合并。
9 | 要求：由于最终会将所有的资源文件id进行合并，因此，所有的资源名称均不能相同。 10 | 11 | ###2.运行ClassLoader加载各Bundle 12 | 和MultiDex的思路是一样的，所有的插件都被加载到同一个ClassLoader当中，因此，不同插件中的Class必须保持包名和类名的唯一。否则，加载过的类不会再次被加载。
13 | 优缺点：各个Bundle之间完全可以相互调用，但是这也造成了各个Bundle之间ClassLoader的非隔离性。并且随着数组的加长，每次findClass的时间会变长，对性能照成一定长度的影响。
14 | 让我们在熟悉一下这张图： 15 | ![multidex](multidex.png) 16 | 17 | 在DynamicAPK框架中，每个Bundle被加载到ClassLoader的调用栈如下： 18 | Bundle的Application：BundleBaseApplication 19 | ->BundleBaseApplication(onCreate) 20 | ->BundleCore(run) 21 | ->BundleImpl(optDexFile) 22 | ->BundleArchiveRevision(optDexFile) 23 | ->BundlePathLoader(installBundleDexs) 24 | ->... 25 |
26 | 如下图所示：
27 | ![ClassLoader加载路路径](bundle_path_load.png) 28 |
29 | ###3.热修复 30 | 由于所有的插件都被加载到同一个ClassLoader当中，因为，热修复的方案都是从dexElements数组的顺序入手，修改expandFieldArray方法的实现，将修复的类放到dexElements的前方。核心代码如下（详见BundlePathLoader）： 31 | ```java 32 | 33 | private static void expandFieldArray(Object instance, String fieldName, 34 | Object[] extraElements,boolean isHotFix) throws NoSuchFieldException, IllegalArgumentException, 35 | IllegalAccessException { 36 | synchronized (BundlePathLoader.class) { 37 | Field jlrField = findField(instance, fieldName); 38 | Object[] original = (Object[]) jlrField.get(instance); 39 | Object[] combined = (Object[]) Array.newInstance( 40 | original.getClass().getComponentType(), original.length + extraElements.length); 41 | if(isHotFix) { 42 | System.arraycopy(extraElements, 0, combined, 0, extraElements.length); 43 | System.arraycopy(original, 0, combined, extraElements.length, original.length); 44 | }else { 45 | System.arraycopy(original, 0, combined, 0, original.length); 46 | System.arraycopy(extraElements, 0, combined, original.length, extraElements.length); 47 | } 48 | jlrField.set(instance, combined); 49 | } 50 | } 51 | 52 | ``` 53 | 54 | 调用的关键代码如下(HotPatchItem.class)：
55 | 56 | ```java 57 | public void optDexFile() throws Exception{ 58 | List files = new ArrayList(); 59 | files.add(this.hotFixFile); 60 | BundlePathLoader.installBundleDexs(RuntimeArgs.androidApplication.getClassLoader(), storageDir, files, false); 61 | } 62 | 63 | public void optHotFixDexFile() throws Exception{ 64 | List files = new ArrayList(); 65 | files.add(this.hotFixFile); 66 | BundlePathLoader.installBundleDexs(RuntimeArgs.androidApplication.getClassLoader(), storageDir, files, true); 67 | } 68 | ``` 69 | 70 | ###4.运行时资源的加载 71 | 所有插件的资源都加载到DelegateResources中，关键代码如下：
72 | DelegateResources.class
73 | 74 | ```java 75 | ... 76 | public static void newDelegateResources(Application application, Resources resources) throws Exception { 77 | List bundles = Framework.getBundles(); 78 | if (bundles != null && !bundles.isEmpty()) { 79 | Resources delegateResources; 80 | List arrayList = new ArrayList(); 81 | arrayList.add(application.getApplicationInfo().sourceDir); 82 | for (Bundle bundle : bundles) { 83 | arrayList.add(((BundleImpl) bundle).getArchive().getArchiveFile().getAbsolutePath()); 84 | } 85 | AssetManager assetManager = AssetManager.class.newInstance(); 86 | for (String str : arrayList) { 87 | SysHacks.AssetManager_addAssetPath.invoke(assetManager, str); 88 | } 89 | //处理小米UI资源 90 | if (resources == null || !resources.getClass().getName().equals("android.content.res.MiuiResources")) { 91 | delegateResources = new DelegateResources(assetManager, resources); 92 | } else { 93 | Constructor declaredConstructor = Class.forName("android.content.res.MiuiResources").getDeclaredConstructor(new Class[]{AssetManager.class, DisplayMetrics.class, Configuration.class}); 94 | declaredConstructor.setAccessible(true); 95 | delegateResources = (Resources) declaredConstructor.newInstance(new Object[]{assetManager, resources.getDisplayMetrics(), resources.getConfiguration()}); 96 | } 97 | RuntimeArgs.delegateResources = delegateResources; 98 | AndroidHack.injectResources(application, delegateResources); 99 | StringBuffer stringBuffer = new StringBuffer(); 100 | stringBuffer.append("newDelegateResources ["); 101 | for (int i = 0; i < arrayList.size(); i++) { 102 | if (i > 0) { 103 | stringBuffer.append(","); 104 | } 105 | stringBuffer.append(arrayList.get(i)); 106 | } 107 | stringBuffer.append("]"); 108 | log.log(stringBuffer.toString(), Logger.LogLevel.DBUG); 109 | } 110 | } 111 | 112 | ... 113 | 114 | ``` 115 |
116 | 上述代码就是将所有Bundle中的资源，通过调用AssetManager的addAssetPath方法，加载到assetManager对象中，然后再用assetManager对象，创建delegateResources对象，并保存在RuntimeArgs.delegateResources当中，然后调用AndroidHack.injectResources方法，对Application和LoadedApk中的mResources成员变量进行注入，代码如下：
117 | ```java 118 | public static void injectResources(Application application, Resources resources) throws Exception { 119 | Object activityThread = getActivityThread(); 120 | if (activityThread == null) { 121 | throw new Exception("Failed to get ActivityThread.sCurrentActivityThread"); 122 | } 123 | Object loadedApk = getLoadedApk(activityThread, application.getPackageName()); 124 | if (loadedApk == null) { 125 | throw new Exception("Failed to get ActivityThread.mLoadedApk"); 126 | } 127 | SysHacks.LoadedApk_mResources.set(loadedApk, resources); 128 | SysHacks.ContextImpl_mResources.set(application.getBaseContext(), resources); 129 | SysHacks.ContextImpl_mTheme.set(application.getBaseContext(), null); 130 | } 131 | ``` 132 | 其中，上述获取LoadedApk的代码，也是通过反射，获取运行时ActivityThread类的LoadedApk对象. 133 | 134 | ###5.运行时动态替换Resource对象 135 | 136 | ####ContextImplHook,动态替换getResources 137 | 为了控制startActivity的时候，能够及时替换Activity的Resource和AssetsManager对象，使用ContextImplHook类对Comtext进行替换，然后动态的返回上一步加载的RuntimeArgs.delegateResources委托资源对象。ContextImplHook的核心代码如下： 138 | ```java 139 | 140 | @Override 141 | public Resources getResources() { 142 | log.log("getResources is invoke", Logger.LogLevel.INFO); 143 | return RuntimeArgs.delegateResources; 144 | } 145 | 146 | @Override 147 | public AssetManager getAssets() { 148 | log.log("getAssets is invoke", Logger.LogLevel.INFO); 149 | return RuntimeArgs.delegateResources.getAssets(); 150 | } 151 | 152 | ``` 153 | ####如何在Activity跳转过程中，动态的替换呢 154 | 通过反射替换ActivityThread的mInstrumentation对象，替换成InstrumentationHook.class,然后就可以在执行startActivity时，拦截其newActivity和callActivityOnCreate方法，在newActivity方法中，动态的替换newActivity的mResources对象。在callActivityOnCreate方法中将ContextImplHook注入到新创建的Activity中。核心代码如下：
155 | ```java 156 | 157 | @Override 158 | public Activity newActivity(Class cls, Context context, IBinder iBinder, Application application, Intent intent, ActivityInfo activityInfo, CharSequence charSequence, Activity activity, String str, Object obj) throws InstantiationException, IllegalAccessException { 159 | Activity newActivity = this.mBase.newActivity(cls, context, iBinder, application, intent, activityInfo, charSequence, activity, str, obj); 160 | if (RuntimeArgs.androidApplication.getPackageName().equals(activityInfo.packageName) && SysHacks.ContextThemeWrapper_mResources != null) { 161 | SysHacks.ContextThemeWrapper_mResources.set(newActivity, RuntimeArgs.delegateResources); 162 | } 163 | return newActivity; 164 | } 165 | 166 | @Override 167 | public Activity newActivity(ClassLoader classLoader, String str, Intent intent) throws InstantiationException, IllegalAccessException, ClassNotFoundException { 168 | Activity newActivity; 169 | try { 170 | newActivity = this.mBase.newActivity(classLoader, str, intent); 171 | if (SysHacks.ContextThemeWrapper_mResources != null) { 172 | SysHacks.ContextThemeWrapper_mResources.set(newActivity, RuntimeArgs.delegateResources); 173 | } 174 | } catch (ClassNotFoundException e) { 175 | String property = Framework.getProperty("ctrip.android.bundle.welcome", "ctrip.android.view.home.CtripSplashActivity"); 176 | if (StringUtil.isEmpty(property)) { 177 | throw e; 178 | } else { 179 | List runningTasks = ((ActivityManager) this.context.getSystemService(Context.ACTIVITY_SERVICE)).getRunningTasks(1); 180 | if (runningTasks != null && runningTasks.size() > 0 && ((ActivityManager.RunningTaskInfo) runningTasks.get(0)).numActivities > 1) { 181 | if (intent.getComponent() == null) { 182 | intent.setClassName(this.context, str); 183 | } 184 | } 185 | log.log("Could not find activity class: " + str, Logger.LogLevel.WARN); 186 | log.log("Redirect to welcome activity: " + property, Logger.LogLevel.WARN); 187 | newActivity = this.mBase.newActivity(classLoader, property, intent); 188 | } 189 | } 190 | return newActivity; 191 | } 192 | 193 | @Override 194 | public void callActivityOnCreate(Activity activity, Bundle bundle) { 195 | if (RuntimeArgs.androidApplication.getPackageName().equals(activity.getPackageName())) { 196 | ContextImplHook contextImplHook = new ContextImplHook(activity.getBaseContext()); 197 | if (!(SysHacks.ContextThemeWrapper_mBase == null || SysHacks.ContextThemeWrapper_mBase.getField() == null)) { 198 | SysHacks.ContextThemeWrapper_mBase.set(activity, contextImplHook); 199 | } 200 | SysHacks.ContextWrapper_mBase.set(activity, contextImplHook); 201 | } 202 | this.mBase.callActivityOnCreate(activity, bundle); 203 | } 204 | 205 | ``` 206 | 207 | 总结如下图,Resource的加载和动态替换： 208 | ![Resource的加载和动态替换](resource_load_replace.PNG) 209 | 210 | ###6.插件Activity在宿主AndroidManifest中的预注册 211 | 每个插件的Activity，必须在宿主的AndroidManifest.xml中进行注册。 212 | 213 | ##DynamicAPK源码导读： 214 | 源代码的目录结构图 215 | ![源码目录](src_dir.png) 216 |

4 | ##Author：莫川 5 |
6 | ##简介 7 | 如何加载未安装apk中的资源文件呢？我们从android.content.res.AssetManager.java的源码中发现，它有一个私有方法addAssetPath，只需要将apk的路径作为参数传入，我们就可以获得对应的AssetsManager对象，然后我们就可以使用AssetsManager对象，创建一个Resources对象，然后就可以从Resource对象中访问apk中的资源了。总结如下：
8 | 9 | - 1.新建一个AssetManager对象 10 | - 2.通过反射调用addAssetPath方法 11 | - 3.以AssetsManager对象为参数，创建Resources对象即可。 12 | 13 | 代码如下：
14 | ```java 15 | package net.mobctrl.hostapk; 16 | 17 | import java.io.File; 18 | 19 | import android.content.Context; 20 | import android.content.res.AssetManager; 21 | import android.content.res.Resources; 22 | 23 | /** 24 | * @Author Zheng Haibo 25 | * @PersonalWebsite http://www.mobctrl.net 26 | * @version $Id: LoaderResManager.java, v 0.1 2015年12月11日 下午7:58:59 mochuan.zhb 27 | * Exp $ 28 | * @Description 动态加载资源的管理器 29 | */ 30 | public class BundlerResourceLoader { 31 | 32 | private static AssetManager createAssetManager(String apkPath) { 33 | try { 34 | AssetManager assetManager = AssetManager.class.newInstance(); 35 | try { 36 | AssetManager.class.getDeclaredMethod("addAssetPath", String.class).invoke( 37 | assetManager, apkPath); 38 | } catch (Throwable th) { 39 | System.out.println("debug:createAssetManager :"+th.getMessage()); 40 | th.printStackTrace(); 41 | } 42 | return assetManager; 43 | } catch (Throwable th) { 44 | System.out.println("debug:createAssetManager :"+th.getMessage()); 45 | th.printStackTrace(); 46 | } 47 | return null; 48 | } 49 | 50 | /** 51 | * 获取Bundle中的资源 52 | * @param context 53 | * @param apkPath 54 | * @return 55 | */ 56 | public static Resources getBundleResource(Context context){ 57 | AssetsManager.copyAllAssetsApk(context); 58 | File dir = context.getDir(AssetsManager.APK_DIR, Context.MODE_PRIVATE); 59 | String apkPath = dir.getAbsolutePath()+"/BundleApk.apk"; 60 | System.out.println("debug:apkPath = "+apkPath+",exists="+(new File(apkPath).exists())); 61 | AssetManager assetManager = createAssetManager(apkPath); 62 | return new Resources(assetManager, context.getResources().getDisplayMetrics(), context.getResources().getConfiguration()); 63 | } 64 | 65 | } 66 | 67 | ``` 68 | 69 | ##DEMO 70 | 注意：我们使用Resources对象，获取资源时，传递的ID必须是离线apk中R文件对应的资源的ID。如果使用getIdentifier方法，第一个参数是资源名称，第二个参数是资源类型，第三个参数是离线apk的包名，切记第三个参数。
71 | 72 | ```java 73 | Resources resources = BundlerResourceLoader.getBundleResource(getApplicationContext()); 74 | imageView = (ImageView)findViewById(R.id.image_view_iv); 75 | if(resources != null){ 76 | String str = resources.getString(resources.getIdentifier("test_str", "string", "net.mobctrl.normal.apk")); 77 | String strById = resources.getString(0x7f050001);//注意，id参照Bundle apk中的R文件 78 | System.out.println("debug:"+str); 79 | Toast.makeText(getApplicationContext(),strById, Toast.LENGTH_SHORT).show(); 80 | 81 | Drawable drawable = resources.getDrawable(0x7f020000);//注意，id参照Bundle apk中的R文件 82 | imageView.setImageDrawable(drawable); 83 | } 84 | ``` 85 | 86 | 上述代码是加载离线apk中的字符串和Drawable资源，那么layout资源呢？ 87 | 88 | ##问题引入 89 | 我们使用LayoutInflate对象，一般使用方法如下：
90 | ```java 91 | View view = LayoutInflater.from(context).inflate(R.layout.main_fragment, null); 92 | ``` 93 | 其中，R.layout.main_fragment我们可以通过上述方法获取其ID，那么关键的一步就是如何生成一个context？直接传入当前的context是不行的。 94 | 解决方案有2个：
95 | - 1.创建一个自己的ContextImpl，Override其方法。
96 | - 2.通过反射，直接替换当前context的mResources私有成员变量。
97 | 当然，我们是使用第二种方案：
98 | 99 | ```java 100 | @Override 101 | protected void attachBaseContext(Context context) { 102 | replaceContextResources(context); 103 | super.attachBaseContext(context); 104 | } 105 | 106 | /** 107 | * 使用反射的方式，使用Bundle的Resource对象，替换Context的mResources对象 108 | * @param context 109 | */ 110 | public void replaceContextResources(Context context){ 111 | try { 112 | Field field = context.getClass().getDeclaredField("mResources"); 113 | field.setAccessible(true); 114 | field.set(context, mBundleResources); 115 | System.out.println("debug:repalceResources succ"); 116 | } catch (Exception e) { 117 | System.out.println("debug:repalceResources error"); 118 | e.printStackTrace(); 119 | } 120 | } 121 | ``` 122 | 123 |
124 | 我们在Activity的attachBaseContext方法中，对Context的mResources进行替换，这样，我们就可以加载离线apk中的布局了。
125 | 126 | ##资源文件的打包过程 127 | 128 | 如果想要做到插件化，需要了解Android资源文件的打包过程，这样可以为每一个插件进行编号，然后按照规则生成R文件。例如，以携程DynamicAPK为例，它将插件的R文件按照如下规则：
129 | 130 | - 1.R文件为int型，前8位代表插件的Id，其中两个特殊的Id：Host是0x7f，android系统自带的是以0x01开头. 131 | - 2.紧跟着的8位是区分资源类型的，比如layout，id,string,dimen等 132 | - 3.后面16位是资源的编号 133 | 134 | 按照上述规则生成对应的插件apk。然后在运行时，我们可以写一个ResourceManager类，它继承自Resource对象，然后所有的Activity，都将其context的mResource成员变量修改为ResourceManager类，然后Override其方法，然后在加载资源时，根据不同的id的前缀，查找对应插件的Resource即可。也就是说，用一个类做分发。 135 | 136 | 137 | ##源码 138 | 139 | https://github.com/nuptboyzhb/AndroidPluginFramework 140 | 141 | ##Android插件化相关资料 142 | 143 | - 1.Android动态加载基础 ClassLoader工作机制 http://segmentfault.com/a/1190000004062880

3 | ##Author:莫川 4 |
5 | ##简介 6 | 上一篇博客讲到，我们可以使用MultiDex.java加载离线的apk文件。需要注意的是，apk中的类是加载到当前的PathClassLoader当中的，如果apk文件过多，可能会出现ANR的情况。那么，我们能不能使用DexClassLoader加载apk呢？当然是可以的！首先看一下[Doc文档](http://developer.android.com/intl/zh-cn/reference/dalvik/system/DexClassLoader.html). 7 | 8 | ```html 9 | A class loader that loads classes from .jar and .apk files containing a classes.dex entry. This can be used to execute code not installed as part of an application. 10 | ``` 11 | 12 | 也就是说，DexClassLoader可以加载一个含有classes.dex文件的压缩包，既可以是jar也可以是apk。那么加载一个离线的apk文件需要注意哪些呢？
13 | 14 | - 1.DexClassLoader的构造方法：
15 | DexClassLoader(String dexPath, String optimizedDirectory, String libraryPath, ClassLoader parent) 16 | 17 | - 2.私有目录
18 | This class loader requires an application-private, writable directory to cache optimized classes. 19 | 20 | 了解到上述两点，我们就可以根据DexClassLoader所需要的参数，动态加载assets中的apk了。 21 | 22 | ##源码
23 | 24 | ### BundleClassLoaderManager
25 | 该类主要是负责管理这些DexClassLoader的，首先，我们定义了一个叫做BundleDexClassLoader的类，它继承自DexClassLoader，用于加载离线的apk文件。每一个apk文件对应一个BundleDexClassLoader,而BundleClassLoaderManager则保存了一个List,在加载的时候，用于查找类。具体代码如下： 26 |
27 | ```java 28 | package net.mobctrl.hostapk; 29 | 30 | import java.io.File; 31 | import java.io.FilenameFilter; 32 | import java.util.ArrayList; 33 | import java.util.List; 34 | 35 | import android.annotation.TargetApi; 36 | import android.content.Context; 37 | import android.os.Build; 38 | 39 | /** 40 | * @Author Zheng Haibo 41 | * @PersonalWebsite http://www.mobctrl.net 42 | * @version $Id: BundleClassLoaderManager.java, v 0.1 2015年12月11日 下午7:30:59 43 | * mochuan.zhb Exp $ 44 | * @Description 45 | */ 46 | @TargetApi(Build.VERSION_CODES.ICE_CREAM_SANDWICH) 47 | public class BundleClassLoaderManager { 48 | 49 | public static List bundleDexClassLoaderList = new ArrayList(); 50 | 51 | /** 52 | * 加载Assets里的apk文件 53 | * @param context 54 | */ 55 | public static void install(Context context) { 56 | AssetsManager.copyAllAssetsApk(context); 57 | // 获取dex文件列表 58 | File dexDir = context.getDir(AssetsManager.APK_DIR, 59 | Context.MODE_PRIVATE); 60 | File[] szFiles = dexDir.listFiles(new FilenameFilter() { 61 | 62 | @Override 63 | public boolean accept(File dir, String filename) { 64 | return filename.endsWith(AssetsManager.FILE_FILTER); 65 | } 66 | }); 67 | for (File f : szFiles) { 68 | System.out.println("debug:load file:" + f.getName()); 69 | BundleDexClassLoader bundleDexClassLoader = new BundleDexClassLoader( 70 | f.getAbsolutePath(), dexDir.getAbsolutePath(), null, 71 | context.getClassLoader()); 72 | bundleDexClassLoaderList.add(bundleDexClassLoader); 73 | } 74 | } 75 | 76 | /** 77 | * 查找类 78 | * 79 | * @param className 80 | * @return 81 | * @throws ClassNotFoundException 82 | */ 83 | public static Class loadClass(Context context,String className) throws ClassNotFoundException { 84 | try { 85 | Class clazz = context.getClassLoader().loadClass(className); 86 | if (clazz != null) { 87 | System.out.println("debug: class find in main classLoader"); 88 | return clazz; 89 | } 90 | } catch (Exception e) { 91 | e.printStackTrace(); 92 | } 93 | for (BundleDexClassLoader bundleDexClassLoader : bundleDexClassLoaderList) { 94 | try { 95 | Class clazz = bundleDexClassLoader.loadClass(className); 96 | if (clazz != null) { 97 | System.out.println("debug: class find in bundle classLoader"); 98 | return clazz; 99 | } 100 | } catch (Exception e) { 101 | e.printStackTrace(); 102 | } 103 | } 104 | throw new ClassCastException(className + " not found exception"); 105 | } 106 | } 107 | 108 | ``` 109 | 110 | 注意点：
111 | 112 | - 1.install方法
113 | install方法主要是将assets中的apk全部拷贝到私有目录，然后再遍历私有目录，使用BundleDexClassLoader加载apk文件，然后将这些BundleDexClassLoader保存到数组中。 114 | 115 | - 2.loadClass方法
116 | 该方法先从当前的ClassLoader中查找需要的类，如果找不到，在从List中遍历查找。 117 | 118 | ### DEMO运行 119 | 在MainActivity中，我们可以通过如下方式，调用apk类中的方法：
120 | ```java 121 | private void loadApk() { 122 | try { 123 | Class clazz = BundleClassLoaderManager.loadClass(getApplicationContext(), 124 | "net.mobctrl.normal.apk.Utils"); 125 | Constructor constructor = clazz.getConstructor(); 126 | Object bundleUtils = constructor.newInstance(); 127 | 128 | Method printSumMethod = clazz.getMethod("printSum", Context.class, 129 | int.class, int.class, String.class); 130 | printSumMethod.setAccessible(true); 131 | Integer sum = (Integer) printSumMethod.invoke(bundleUtils, 132 | getApplicationContext(), 10, 20, "计算结果"); 133 | System.out.println("debug:sum = " + sum); 134 | } catch (ClassNotFoundException e) { 135 | e.printStackTrace(); 136 | } catch (SecurityException e) { 137 | e.printStackTrace(); 138 | } catch (NoSuchMethodException e) { 139 | e.printStackTrace(); 140 | } catch (IllegalArgumentException e) { 141 | e.printStackTrace(); 142 | } catch (InstantiationException e) { 143 | e.printStackTrace(); 144 | } catch (IllegalAccessException e) { 145 | e.printStackTrace(); 146 | } catch (InvocationTargetException e) { 147 | e.printStackTrace(); 148 | } 149 | } 150 | ``` 151 | 152 | 与MultiDex不同时，我们是通过BundleClassLoaderManager来加载类的，而不是当前的ClassLoader。 153 | 154 | ### 改进方案 155 | 正如BundleClassLoaderManager中的loadClass方法，其实我们创建一个ClassLoader对象，通过重写当前ClassLoader的findClass方法即可，然后在Override的findClass方法中，首先从当前ClassLoader中查找类，然后再从BundleDexClassLoader中遍历查找，这样既可以在Host项目中调用Bundle中的类，也能够在Bundle中调用Host中的类。 156 | 157 | ```java 158 | 159 | mClassLoader = new ClassLoader(super.getClassLoader()) { 160 | 161 | @Override 162 | protected Class findClass(String className) 163 | throws ClassNotFoundException { 164 | Class clazz = BundleClassLoaderManager.loadClass(context,className); 165 | if (clazz == null) { 166 | throw new ClassNotFoundException(className); 167 | } 168 | return clazz; 169 | } 170 | }; 171 | 172 | ``` 173 | 174 | ##总结 175 | 上一篇博客和这一篇博客将的都是类的加载。如果所需要加载的类都是工具类，不需要加载资源等，那么上面的方案都没啥问题。但是如果加载的类是Fragment或者Activity等UI，需要引用资源文件，这又改如何处理呢？ 176 | 177 | 下一篇博文：Android资源的离线加载。 178 | 179 | 180 |

#Android插件化基础（4），动态启动插件中的Activity 2 | 3 |
4 | ##Author：莫川 5 |
6 | ##简介 7 | 如何动态启动插件中的Activity呢？我们首先分析，启动插件中的Activity需要做那些准备？ 8 | 9 | - 1.插件中Activity类的加载
10 | 也就是ClassLoader的问题。由第一节课中的MultiDex可以知道，我们可以动态的加载apk，然后将插件中的class加载到当前的ClassLoader当中。这样，插件中的class和宿主中的class同属一个ClassLoader,它们之间的相互调用问题也就解决了。 11 | - 2.插件中Activity在AndroidManifest.xml中的注册问题
12 | 由于插件apk有自己的AndroidManifest文件，为了能够在运行时，动态启动插件中的Activity，需要在打包时，将插件apk的Activity注册移动到宿主apk的AndroidManifest文件中。 13 | - 3.插件中Activity的资源加载问题
14 | 处理插件中的资源加载问题，是插件化最难的问题之一!我们需要考虑很多问题：
15 | 1.插件Activity运行时如何实时获取Resources对象，并且能够根据插件包名对应下的R文件的id，查找到Resources中的资源。 16 | 2.插件apk中的资源文件与其他插件及宿主之间的资源名称冲突如何解决？ 17 | 3.宿主及各插件的资源如何统一并且方便的管理？ 18 | 19 | ##问题的解决： 20 | 21 | ###1.类的加载 22 | 我们使用之前我们改造的AssetsMultiDexLoader，来加载assets目录下的apk。由于之前的博客已经说明了问题，再次不在赘述。 23 | 24 | ###2.插件中的Activity在宿主AndroidManifest中注册 25 | 这件事情需要在打包时处理，也就是说，我们需要改造我们的打包工具，在打包时，将各个插件的AndroidManifest文件合并到宿主AndroidManifest文件中。 26 | 27 | ###3.插件资源的加载问题 28 | 29 | 我们需要在编译过程和运行过程分别做处理： 30 | 31 | ####3.1 编译过程 32 | 我们首先回顾一下Android打包的过程：
33 | 1.生成R.java文件
34 | 比如：
35 | ```xml 36 | aapt package -f -m -J ./gen -S res -M AndroidManifest.xml -I D:\android_sdk_for_studio\platforms\android-22\android.jar 37 | ``` 38 | 2.清空bin目录
39 | 清空上次生成的文件 40 | 3.编译java文件和jar包
41 | ```xml 42 | javac -encoding GBK -target 1.5 -bootclasspath D:\android_sdk_for_studio\platforms\android-22\android.jar -d bin src\net\mobctrl\normal\apk\*.java gen\net\mobctrl\normal\apk\R.java -classpath libs\*.jar 43 | ``` 44 | 4.使用dx工具打包成classes.dex
45 | ```xml 46 | dx --dex --output=C:\Users\mochuan.zhb\newworkspace\BundleApk5\bin\classes.dex C:\Users\mochuan.zhb\newworkspace\BundleApk5\bin\ 47 | ``` 48 | 5.编译成资源文件
49 | ```xml 50 | aapt package -f -M AndroidManifest.xml -S res -I D:\android_sdk_for_studio\platforms\android-22\android.jar -F bin\resources.ap_ --non-constant-id 51 | ``` 52 | 6.使用sdklib.jar工具生成未签名的apk
53 | ``` 54 | java -cp D:\android_sdk_for_studio\tools\lib\sdklib.jar com.android.sdklib.build.ApkBuilderMain bin\MyCommond.apk -v -u -z bin\resources.ap_ -f bin\classes.dex -rf C:\Users\mochuan.zhb\newworkspace\BundleApk5\src 55 | ``` 56 | 7.使用jarsigner对apk进行签名
57 | jarsigner -verbose -keystore C:\test.keystore -storepass 123456 -keypass 123456 -signedjar C:\projectdemo-signed.apk C:\test.apk test 58 |
59 | 60 | ###3.2编译过程的修改 61 | 为了解决插件与插件之间以及宿主之间的资源冲突问题，我们需要对插件进行编号，修改R文件的生成过程。我们知道，R文件中的ID是一个int类型，总共32位。那么这32位分别代表什么含义呢？
62 | 1.前8位代表插件的packageId，其中两个特殊的Id：Host是0x7f，android系统自带的是以0x01开头.
63 | 2.紧跟着的8位是区分资源类型的，比如layout，id,string,dimen等
64 | 3.后面16位是资源的编号
65 | 66 | 为了解决资源的命名冲突，一般由以下2中方法：
67 | ####1.约定
68 | 团队在开发时，对资源的命名进行约定，比如各业务线按照一定的规则命名，大家准守规则，避免重复。 69 | 然后在打包时，我们对各个插件的资源进行合并，统一生成R文件，所有插件和宿主的R文件内容都是完全一样的，资源都保存在宿主项目的资源中。
70 | 说明：Google使用的Android打包过程，就是这样的。比如主project依赖lib_project1,lib_project2等，在编译主project的时候，它就将各个lib项目的资源都复制到主project中，然后使用aapt进行统一生成R文件，生成多个不同包名的R文件，但是R文件的内容是完全一样的。
71 | ####2.修改aapt
72 | 为了从机制上避免资源名称重复的问题，我们可以通过修改aapt的源码，让其可以根据不同的packageId生成不同的id。也就是说，R文件中的id由以下32位组成：
73 | [packageId(8)][resourceType(8)][resourcesSeq(16)]
74 | 我们为每一个插件分配一个packageId,范围是(1,127). 75 | 修改aapt的源码之后，我们需要改动打包过程中的第一步和第五步，在生成R文件和编译资源的时候，使用我们改造后的aapt。这样，最终生成的apk，其R文件就是按照我们分配的方式。
76 | 我们可以通过反编译，查看test.apk中的R文件，如下图所示，我们设定的packageId是5： 77 | ![de](decode.jpg) 78 | 【test.apk的反编译图】 79 | 反编译之后的id需要转化为16进制显示。
80 | *注*：
81 | 反编译步骤：
82 | 1.解压apk文件
83 | 2.使用d2j-dex2jar工具，将dex转化为jar
84 | 3.使用Java-Decompiler反编译jar
85 | 86 | ###3.3运行过程中资源的加载 87 | 88 | ####1.将插件apk加载到当前的AssetsManager中 89 | 核心代码： 90 | 91 | ```java 92 | /** 93 | * 修改AssetManager 94 | * 95 | * @param assetManager 96 | * @param apkPaths 97 | * @return 98 | */ 99 | private static AssetManager modifyAssetManager(AssetManager assetManager, 100 | List apkPaths) { 101 | if (apkPaths == null || apkPaths.size() == 0) { 102 | return null; 103 | } 104 | try { 105 | for (String apkPath : apkPaths) { 106 | try { 107 | AssetManager.class.getDeclaredMethod("addAssetPath", 108 | String.class).invoke(assetManager, apkPath); 109 | } catch (Throwable th) { 110 | System.out.println("debug:createAssetManager :" 111 | + th.getMessage()); 112 | th.printStackTrace(); 113 | } 114 | } 115 | return assetManager; 116 | } catch (Throwable th) { 117 | System.out.println("debug:createAssetManager :" + th.getMessage()); 118 | th.printStackTrace(); 119 | } 120 | return null; 121 | } 122 | 123 | /** 124 | * 获取整个App的资源管理器中的资源 125 | * 126 | * @param context 127 | * @param apkPath 128 | * @return 129 | */ 130 | public static Resources getAppResource(Context context) { 131 | System.out.println("debug:getAppResource ..."); 132 | AssetsManager.copyAllAssetsApk(context); 133 | // 获取dex文件列表 134 | File dexDir = context.getDir(AssetsManager.APK_DIR, 135 | Context.MODE_PRIVATE); 136 | File[] szFiles = dexDir.listFiles(new FilenameFilter() { 137 | 138 | @Override 139 | public boolean accept(File dir, String filename) { 140 | return filename.endsWith(AssetsManager.FILE_FILTER); 141 | } 142 | }); 143 | if (szFiles == null || szFiles.length == 0) { 144 | return context.getResources(); 145 | } 146 | System.out.println("debug:getAppResource szFiles = "+szFiles.length); 147 | List apkPaths = new ArrayList(); 148 | for (File f : szFiles) { 149 | Log.i(TAG, "load file:" + f.getName()); 150 | apkPaths.add(f.getAbsolutePath()); 151 | System.out.println("debug:apkPath = " + f.getAbsolutePath()); 152 | } 153 | AssetManager assetManager = modifyAssetManager(context.getAssets(), 154 | apkPaths); 155 | AppResource resources = new AppResource( 156 | assetManager, context.getResources().getDisplayMetrics(), 157 | context.getResources().getConfiguration()); 158 | return resources; 159 | } 160 | 161 | ``` 162 | 163 | ####2.Application中Resources的加载
164 | 核心代码
165 | ```java 166 | 167 | public class HostApplication extends Application { 168 | 169 | private Resources mAppResources = null; 170 | private Resources mOldResources = null; 171 | 172 | @Override 173 | public void onCreate() { 174 | super.onCreate(); 175 | mOldResources = super.getResources(); 176 | AssetsMultiDexLoader.install(this);// 加载assets中的apk 177 | installResource(); 178 | } 179 | 180 | @Override 181 | public Resources getResources() { 182 | if(mAppResources == null){ 183 | return mOldResources; 184 | } 185 | return this.mAppResources; 186 | } 187 | 188 | private void installResource() { 189 | if (mAppResources == null) { 190 | mAppResources = BundlerResourceLoader.getAppResource(this);// 加载assets中的资源对象 191 | } 192 | } 193 | 194 | @Override 195 | public AssetManager getAssets() { 196 | if (this.mAppResources == null) { 197 | return super.getAssets(); 198 | } 199 | return this.mAppResources.getAssets(); 200 | } 201 | 202 | } 203 | 204 | ``` 205 | 206 | ####3.插件Activity替换Resource对象
207 | 以BundleActivity为例：
208 | ```java 209 | public class BundleActivity extends BaseActivity { 210 | 211 | @Override 212 | protected void onCreate(Bundle savedInstanceState) { 213 | super.onCreate(savedInstanceState); 214 | setContentView(R.layout.bundle_layout); 215 | findViewById(R.id.text_view).setOnClickListener(new View.OnClickListener() { 216 | 217 | @Override 218 | public void onClick(View view) { 219 | Toast.makeText(getApplicationContext(), "Hello", Toast.LENGTH_LONG).show(); 220 | } 221 | }); 222 | } 223 | 224 | @Override 225 | public Resources getResources() { 226 | return getApplication().getResources(); 227 | } 228 | 229 | } 230 | ``` 231 | 最关键的是，重写getResources()方法，使用Application的Resource替换当前的Resource方法。 232 | 233 | #参考 234 | [1.关于Android如何动态加载res](http://nobodycare.me/2014/11/07/about-loading-res-from-apk-directly/)
