just loading the new version apk file to achieve. 8 | ( dependent libraries [ApkDiffPatch], [xHook]. ) 9 | 10 | [UnityAndroidHotUpdate]: https://github.com/sisong/UnityAndroidHotUpdate 11 | [ApkDiffPatch]: https://github.com/sisong/ApkDiffPatch 12 | [xHook]: https://github.com/iqiyi/xHook 13 | [UnityAndroidIl2cppPatchDemo]: https://github.com/noodle1983/UnityAndroidIl2cppPatchDemo 14 | [HDiffPatch]: https://github.com/sisong/HDiffPatch 15 | [bsdiff]: http://www.daemonology.net/bsdiff/ 16 | [archive-patcher]: https://github.com/andrewhayden/archive-patcher 17 | [v2+ sign]: https://source.android.com/security/apksigning/v2 18 | 19 | 20 | ## The effect of this solution 21 | When the android user running the app, update logic can complete the task of downloaded the new version app in the background; When the app is restarted, user run with new version app (not need reinstall through system, the "hot update" means this)! 22 | 23 | ## Theory of hot update 24 | When installing the Android app, the apk file is stored in path ```getApplicationContext().getPackageResourcePath()```, and the native abi library files are decompressed and stored in path ```getApplicationContext().getApplicationInfo().nativeLibraryDir``` , including libmain.so, libunity.so, libil2cpp.so or libmono*.so, etc... 25 | This solution will store the updated version apk file to the update path in ```getApplicationContext().getFilesDir().getPath()```, and decompress the changed local abi library files from apk to the update path; When the app restarts, use the hook and java layer code to intercept the c file API in Unity's library files, map access path from the apk file and library files to the new apk file and new library files. 26 | (The idea Hook Unity library's C file API to implement hot update, comes from [UnityAndroidIl2cppPatchDemo], thanks.) 27 | 28 | ## Feature 29 | * **Implement simple and run fast** 30 | The theory and implement are simple, and support hot update of code and resources; support il2cpp and mono two code backend, support libunity.so, libmono.so and other library files changes; support libmain.so little(RELEASE) version changes, not support Unity main(MAJOR & MINOR) version changes; 31 | Solution import into project is simple, easy to modify by yourself; (the description of import project is at back of this document.) 32 | After the hot update, the execution performance of the app is not affected, unlike the slow performance and Activity compatibility problems after using the plugin (or virtual) apk solution; 33 | This solution will not disturb your Unity project development, not need other program language or constraints, such as lua js or IL runtime etc... 34 | * **The patch package by downloaded is small** 35 | Not need to download the complete apk file, you just need to download the difference between the existing version and the latest version; then you can create the latest version apk file on device; 36 | You can select [ApkDiffPatch] for apk file diff&patch, it can generate very small patch package; for example, just some simple code changes, the patch package size about hundreds of KB. 37 | * **Development environment and compatibility** 38 | Test used Unity5.6, Unity2017, Unity2018, Unity2019; 39 | Test used mono and il2cpp backend; 40 | Test on armeabi-v7a arm64-v8a and x86 device; 41 | Test supported Andorid4.1+; but maybe only supported Andorid5+ when using Unity5.6 or Unity2017 + il2cpp backend, you need tests; 42 | It is generally compatible, if the main(MAJOR & MINOR) version of Unity unchanged (jni lib's API will not change) and no new .so library files been added; 43 | The project's other .so libraries can be added to the list of libraries that are allowed to be advance load, for compatible with the hot update (added in the HotUnity.java file, see the description of improt project); 44 | Tested to create a simple app with the same Unity main version, and successfully hot updated to an existing complex game app; 45 | Of course, those involving permissions or third-party services, etc., their compatibility need more testing. 46 | 47 | 48 | ## How to import into your Unity project for testing 49 | * Export project: select Gradle and export project in your Unity project, and then modify it and do packaging by Android Studio; 50 | * Modify the exported project: 51 | add libhotunity.so(rebuild in path ```project_hook_unity_jni```) to project jniLibs; 52 | add ```com/github/sisong/HotUnity.java``` to project; (You can add the .so in this file that need hot update, which will be loaded if exist new version;) 53 | edit file UnityPlayerActivity.java in project; add code: ```import com.github.sisong.HotUnity;```, and add code: ```HotUnity.hotUnity(this);``` before ```mUnityPlayer = new UnityPlayer(this);``` 54 | * If you need to support upgrading little(RELEASE) version of Unity, you need to use the FixUnityJar program(code in path ```project_fix_unity_jar/fix_unity_jar```) to modify the file unity-classes.jar in the export project, and add libnull.so(rebuild in path ```project_fix_unity_jar/null_lib ```) to project jniLibs; 55 | * APK installation for compatibility with Android 10, need: 56 | Edit AndroidProject's ```AndroidManifest.xml``` file's ```application``` node, add: 57 | ```xml 58 | 59 | 61 | 62 | 63 | ``` 64 | Create ```/xml/update_files.xml``` file in AndroidProject's ```res``` path, Enter the following content: 65 | ```xml 66 | 67 | 68 | 69 | 70 | ``` 71 | * Package the test project by Android Studio (you can automate the process of exporting modifying and packaging in Unity with the editor extension), the app should be able to running normally on the device; now you need test the app "hot" update to a new version; 72 | * Manual hot update test process: you have a new version app named update.apk, placed it in the HotUpdate subdirectory of the ```getApplicationContext().getFilesDir().getPath()``` (device path ```/data/data//files/HotUpdate/```); Decompress the *.so file in ```lib//``` from update.apk, and place it in the directory ```HotUpdate/update.apk_lib/``` (can also dispose only changed .so file); restart the app on the device, you should be able to see that the new version is already running! 73 | 74 | 75 | ## How to automate hot update by app 76 | (the following info provides an optional way to do this) 77 | * We have a new version apk, I can use the diff tool to generate patch between the old and new versions; put the version upgrade info and patch files on the server; 78 | * When the app running, it checks the upgrade info and download the patch file; the app call patch algorithm to generate a new version apk(ie ```HotUpdate/update.apk```) using the latest apk and patch file; At the same time, choose to cache the changed .so files in this new apk to the ```HotUpdate/update.apk_lib/``` path; If you need a "cold" re-install choose not to cache .so files; 79 | * Generate patch file between apks and merge it on device, used the [ApkDiffPatch]; if you want test diff program, you can download it at [releases](https://github.com/sisong/ApkDiffPatch/releases); The patch process needs to be executed on the user device. provided function virtualApkPatch() in java, and native function virtual_apk_patch() can be used in C#. 80 | * Note: ApkDiffPatch is specially optimized for zip file. Generally, it generates smaller patch file size than [bsdiff] or [HDiffPatch]; The ZipDiff tool has special requirements for the input apk file, if the apk has [v2+ sign], then you need to normalized the apk files by the ApkNormalized tool; Then use AndroidSDK#apksigner to re-sign the apk; All the apks released for user need to done this process, this is to byte by byte restore the apk when patching; (apk after this processed, it is also compatible with the patch size optimization scheme [archive-patcher] of the Google Play Store) 81 | 82 | 83 | ## Recommend a process for multi version update 84 | ``` 85 | v0 -> new install(v0) 86 | 87 | v1 -> diff(v0,v1) -> pat01 ; v0: patch(v0,download(pat01)) -> v1 + cache_lib(v1) 88 | ( if error on patch then: download(v1) -> v1 + install(v1) ) 89 | 90 | v2 -> diff(v0,v2) -> pat02 ; v0: patch(v0,download(pat02)) -> v2 + cache_lib(v2) 91 | diff(v1,v2) -> pat12 ; v1: patch(v1,download(pat12)) -> v2 + cache_lib(v2) 92 | 93 | v3 -> (if no patch for v0) ; v0: download(v3) -> v3 + install(v3) 94 | diff(v1,v3) -> pat13 ; v1: patch(v1,download(pat13)) -> v3 + cache_lib(v3) 95 | diff(v2,v3) -> pat23 ; v2: patch(v2,download(pat23)) -> v3 + cache_lib(v3) 96 | 97 | if is_need_install(v3,v4): 98 | v4 -> (if no patch for v0) ; v0: download(v4) -> v4 + install(v4) 99 | diff(v1,v4) -> pat14 ; v1: patch(v1,download(pat14)) -> v4 + install(v4) 100 | diff(v2,v4) -> pat24 ; v2: patch(v2,download(pat24)) -> v4 + install(v4) 101 | diff(v3,v4) -> pat34 ; v3: patch(v3,download(pat34)) -> v4 + install(v4) 102 | 103 | v5 -> (if no patch for v0) ; v0: download(v5) -> v5 + install(v5) 104 | (if no patch for v1) ; v1: download(v5) -> v5 + install(v5) 105 | diff(v2,v5) -> pat25 ; v2: patch(v2,download(pat25)) -> v5 + install(v5) 106 | diff(v3,v5) -> pat35 ; v3: patch(v3,download(pat35)) -> v5 + install(v5) 107 | diff(v4,v5) -> pat45 ; v4: patch(v4,download(pat45)) -> v5 + cache_lib(v5) 108 | ``` 109 | This new version and patch release process needs to be automated: normalized apk, re-signing, creating patches, generate config, etc... 110 | 111 | 112 | ## Defect 113 | * After changed API between Java and Unity, apk can't be hot update, the new apk needs to be installed; After changed the Unity main(MAJOR & MINOR) version, apk can't be hot update, and the same Unity main version can continue to hot update; 114 | * Can not switch between il2cpp and mono backend apks by hot update, the new apk needs to be installed; 115 | * The solution can only support Android and can't be applied on iOS; (The app developed by Unity run on PC, if needs difference update, you can using [HDiffPatch] to diff&patch between directory.) 116 | * The diff&patch algorithm selected [ApkDiffPatch], which may not support this situation: apk must support [v2+ sign], but released apk cannot be signed by self, then it is impossible to version control and diff; 117 | * The new apk file and cached .so files take up disk space; A recommended solution: fixed Unity version, initial version with a minimized apk (or obb split mode), subsequent updates are the full version; (Another possible improvement is to use the concept of virtual apk: Use hook to map the access to the original apk file when file API access unchanged entry files in virtual apk; the patch process also requires a new implementation; a similar implementation see [UnityAndroidIl2cppPatchDemo].) 118 | 119 | 120 | by housisong@gmail.com 121 | -------------------------------------------------------------------------------- /README.md: -------------------------------------------------------------------------------- 1 | # [UnityAndroidHotUpdate] 2 | [![release tag](https://img.shields.io/github/v/tag/sisong/UnityAndroidHotUpdate?label=release%20tag)](https://github.com/sisong/UnityAndroidHotUpdate/releases) 3 | [![license](https://img.shields.io/badge/license-MIT-blue.svg)](LICENSE) 4 | [![+issue Welcome](https://img.shields.io/github/issues-raw/sisong/UnityAndroidHotUpdate?color=green&label=%2Bissue%20welcome)](https://github.com/sisong/UnityAndroidHotUpdate/issues) 5 | 6 | [[README English](README.en.md)] 7 | 提供了一个在Android上热更新Unity开发的app的方案，支持代码和资源；不依赖其他语言(lua,js等)不干涉项目开发过程；它通过直接加载新版本apk文件来实现的。 8 | ( 依赖的库 [ApkDiffPatch], [xHook]. ) 9 | 10 | [UnityAndroidHotUpdate]: https://github.com/sisong/UnityAndroidHotUpdate 11 | [ApkDiffPatch]: https://github.com/sisong/ApkDiffPatch 12 | [xHook]: https://github.com/iqiyi/xHook 13 | [UnityAndroidIl2cppPatchDemo]: https://github.com/noodle1983/UnityAndroidIl2cppPatchDemo 14 | [HDiffPatch]: https://github.com/sisong/HDiffPatch 15 | [bsdiff]: http://www.daemonology.net/bsdiff/ 16 | [archive-patcher]: https://github.com/andrewhayden/archive-patcher 17 | [v2版及以上签名]: https://source.android.com/security/apksigning/v2 18 | 19 | 20 | ## 该方案的效果 21 | Android用户在使用app过程中，更新逻辑可以在后台完成下载新版本的任务，当app重新启动后用户看到的是新版本的app(不需要系统安装); 这里的“热更”就是指不需要经过系统的重新安装就拥有了新版本! 22 | 23 | 24 | ## 热更原理 25 | Android程序在安装后,apk文件存放在```getApplicationContext().getPackageResourcePath()```;并将其中相应abi的库文件解压存放到了```getApplicationContext().getApplicationInfo().nativeLibraryDir```,其中包括libmain.so,libunity.so,libil2cpp.so or libmono*.so,等; 26 | 本方案会在app运行中，将更新到的新版本apk存放到```getApplicationContext().getFilesDir().getPath()```的更新路径,并将apk中本机abi并发生了改变的库文件解压到更新路径; 当app重启后用hook和java层代码配合,将unity相关库访问apk文件和lib库文件路径的c文件访问函数映射到访问我们准备好的新的apk文件和lib路径。 27 | ( Hook Unity库的C文件API来实现热更的思路来源于[UnityAndroidIl2cppPatchDemo]，感谢，这里做了一些简化和改进。 ) 28 | 29 | 30 | ## 特性 31 | * **简单快速** 32 | 原理和实现简单，并且支持代码和资源的热更新;同时支持il2cpp与mono这2种代码打包方式，支持libunity.so、libmono.so等库文件变动，支持libmain.so的RELEASE小版本改动，不支持Unity大版本(MAJOR和MINOR版本)变动； 33 | 接入项目简单，容易修改定制;（本文后面有接入项目说明） 34 | 热更新后app执行速度不受影响，不像使用插件化方案后遇到的速度慢和Activity兼容等问题； 35 | 这是一个几乎不改变Unity开发流程的方案，不需要引入额外的语言(如lua或js等)，也不需要一个额外的中间层解释器(如ILRuntime)、动态加载反射、手工绑定等工作。 36 | * **下载流量小** 37 | 不需要下载完整的apk文件，而只需要下载已有版本和最新版本之间的差异就可以了；然后在用户本地合成新的apk文件； 38 | 这里选择用的[ApkDiffPatch]方案，可以生成非常小的补丁；比如只是一些简单代码修改，补丁一般在百k级别。 39 | * **运行环境和兼容性** 40 | 在Unity5.6、Unity2017、Unity2018、Unity2019的多个版本上测试过； 41 | 测试过分别使用mono代码后端和il2cpp代码后端； 42 | 测试过armeabi-v7a、arm64-v8a和x86的设备； 43 | 一般支持Andorid4.1及以上的系统了；但使用Unity5.6或Unity2017和il2cpp代码后端时可能只支持Andorid5及以上,你需要测试； 44 | 在发布使用的Unity大版本(MAJOR & MINOR)没有变化(jni库的API不变)和没有新增.so库文件的情况下，一般都可以兼容； 45 | 项目的常规.so库可以添加到允许更新的库列表中提前加载从而兼容热更(在HotUnity.java文件中添加,参见接入项目说明)； 46 | 测试过用相同的Unity大版本新建了一个最简单的app，也可以更新到一个已有的复杂的游戏app； 47 | 当然某些涉及权限、特殊第三方业务等是否兼容还需要更多测试。 48 | 49 | 50 | ## 如何接入你的项目测试 51 | * 导出项目: 将你的Unity项目选择Gradle导出项目,以便修改后交给Android Studio进行打包; 52 | * 修改导出的项目: 53 | 将libhotunity.so文件(注意abi路径对应,build项目在```project_hook_unity_jni```目录里)复制到项目的jniLibs下的相应子目录中； 54 | 将```com/github/sisong/HotUnity.java```文件复制到项目源代码的java相应路径中； (可以在这个文件中添加你需要支持热更的.so，这会立即加载可能存在的新版本库) 55 | 在项目的UnityPlayerActivity.java文件中```import com.github.sisong.HotUnity;```，并且在```mUnityPlayer = new UnityPlayer(this);```代码之前添加代码```HotUnity.hotUnity(this);``` 56 | * 如果你需要支持升级发布用的Unity的小版本，那么需要用FixUnityJar程序(代码在```project_fix_unity_jar/fix_unity_jar```路径里)修改导出项目中文件unity-classes.jar，并且将libnull.so文件(build项目在```project_fix_unity_jar/null_lib```目录里)复制到项目的jniLibs下的相应子目录中； 57 | * 为了兼容Android10安装APK，需要： 58 | 在安卓工程的```AndroidManifest.xml```文件的```application```节点中添加 59 | ```xml 60 | 61 | 63 | 64 | 65 | ``` 66 | 在安卓工程的```res```目录创建```/xml/update_files.xml```文件，内容为： 67 | ```xml 68 | 69 | 70 | 71 | 72 | ``` 73 | * 用Android Studio打包测试项目（你可以把这个导出、修改、打包的过程在Unity中利用编辑器扩展自动化下来；后续本仓库会更新到Demo中），app在设备上应该能够正常运行; 现在你需要测试热更新到一个新版本； 74 | * 手工热更新测试过程：假设有了修改过的新版本apk命名成update.apk,放置到```getApplicationContext().getFilesDir().getPath()```目录的HotUpdate子目录下（一般设备上路径```/data/data//files/HotUpdate/```）； 将update.apk包中```lib/<本测试设备abi>/```中的*.so文件解压后直接放置到```HotUpdate/update.apk_lib/```目录下（可以只放置有修改过的.so文件）； 重新运行设备上安装的app，你应该可以看到，已经运行的是新版本！ 75 | 76 | 77 | ## 如何在正式app里自动化热更 78 | app热更应该是一个程序自动化的过程，它将代替我们上面的手工测试过程；（本方案提供了一种可选实现路径） 79 | * 假设开发了新版本，我可以用diff工具生成新旧版本之间的补丁；将版本升级信息和补丁文件放到服务器上； 80 | * 客户运行app时检查到升级信息并下载到相应的补丁文件，app用patch算法将本机最新apk和补丁生成新版本apk(即```HotUpdate/update.apk```), 并选择将apk中有修改过的.so文件缓存到```HotUpdate/update.apk_lib/```路径；需要“冷”安装时选择不缓存.so文件； 81 | * 生成apk间的补丁和在设备上合并，使用了[ApkDiffPatch]项目; diff程序如果不想自己编译，可以在[releases](https://github.com/sisong/ApkDiffPatch/releases)下载到；patch过程需要在用户设备上执行，java中提供了virtualApkPatch()函数，C#中可以使用native的virtual_apk_patch()函数； 82 | * 注意：ApkDiffPatch针对zip进行了特别的优化，一般比[bsdiff]和[HDiffPatch]生成更小的补丁，其ZipDiff工具对输入的apk文件有特别的要求，如果apk有[v2版及以上签名]，那需要用库提供的ApkNormalized工具对apk进行标准化，然后再用AndroidSDK#apksigner对apk重新进行签名；所有对用户发布的apk都需要经过这个处理，这是为了patch时能够原样还原apk；（经过这个处理过的apk,也兼容谷歌Play商店的补丁大小优化方案[archive-patcher]） 83 | 84 | 85 | ## 推荐一个多版本更新流程（较复杂的示例,考虑了支持需要重新安装的情况） 86 | ``` 87 | v0 -> new install(v0) 88 | 89 | v1 -> diff(v0,v1) -> pat01 ;
