skia 进行软件渲染和硬件渲染的性能差异，顺便演示 chromium 的渲染和 android 对接的方式。 4 | 5 | 在 demo 中主要演示了划线的功能，对比 chromium 中 canvas 的划线，这里演示的方法应该是 canvas 划线的性能上限，可以用来评估 chromium 渲染引入的性能损失情况。 6 | 7 | -

demo_apk 2 | 3 | `demo_apk` 可以构建出一名为`DemoApk.apk`的Android应用，它和普通的Android应用最大的不同就是构建方式。一般的Android开发者使用AndroidStudio等IDE来构建Android应用，在chromium中不使用这些IDE而使用gn。 4 | 5 | chromium提供了一套gn配置用来打包各种Android组件，包括 apk,aar,jar 等。主要的脚本位于`//build/config/android/`目录下。可以重点查看以下两个文件： 6 | 7 | ```gn 8 | //build/config/android/config.gni 9 | //build/config/android/rules.gni 10 | ``` 11 | 12 | ## demo_apk 构成 13 | 14 | demo_apk 由以下几部分组成： 15 | 16 | 1. `AndroidManifest.xml`：Android应用的描述文件，包括权限定义，icon等； 17 | 2. `res`: Android应用的资源文件，包括UI布局，图片，字符串等； 18 | 3. `src`: 源代码文件； 19 | 4. `cpp`: 保存 JNI 相关代码； 20 | 21 | ## JNI 22 | 23 | gn提供了从java代码生成JNI/C++头文件的脚本，具体信息参考`base/android/jni_generator/README.md`。 -------------------------------------------------------------------------------- /demo_android/demo_apk/cpp/demo_apk_library_loader.cc: -------------------------------------------------------------------------------- 1 | #include "base/android/jni_android.h" 2 | // #include "content/public/app/content_jni_onload.h" 3 | // #include "content/public/app/content_main.h" 4 | 5 | #include "base/android/base_jni_onload.h" 6 | #include "base/logging.h" 7 | 8 | //#include "demo/demo_shell/app/demo_shell_content_main_delegate.h" 9 | 10 | JNI_EXPORT jint JNI_OnLoad(JavaVM* vm, void* reserved) { 11 | DLOG(INFO) << "[demo_apk] JNI_OnLoad start"; 12 | // 这个初始化是必要的，因为LibraryLoader依赖它，大量的base::android::*都依赖它 13 | // 它其实就是将vm保存为了内部的全局变量 14 | base::android::InitVM(vm); 15 | // 下面这个初始化在这个程序中不是必须的，但是推荐加上，主要是初始化了ClassLoader 16 | if (!base::android::OnJNIOnLoadInit()) 17 | return false; 18 | 19 | // 我们没有使用（crazy linker）动态注册JNI函数的方式，所以这里不需要以下代码 20 | // if (!RegisterMainDexNatives(env) || !RegisterNonMainDexNatives(env)) { 21 | // return -1; 22 | // } 23 | 24 | DLOG(INFO) << "[demo_apk] JNI_OnLoad finished"; 25 | return JNI_VERSION_1_4; 26 | } 27 | -------------------------------------------------------------------------------- /demo_android/demo_apk/cpp/demo_foo.cc: -------------------------------------------------------------------------------- 1 | #include "demo/demo_android/demo_apk/cpp/demo_foo.h" 2 | 3 | #include "base/android/jni_android.h" 4 | #include "base/android/jni_string.h" 5 | #include "base/android/scoped_java_ref.h" 6 | #include "base/bind.h" 7 | #include "base/lazy_instance.h" 8 | 9 | #include "demo/demo_android/demo_apk/demo_apk_jni_headers/DemoFoo_jni.h" 10 | 11 | namespace demo_jni { 12 | 13 | base::android::ScopedJavaGlobalRef j_demo_foo; 14 | 15 | void DemoFoo::HelloDemoFoo(JNIEnv* env, const base::android::JavaParamRef& who) { 16 | LOG(INFO)<<"[demo_foo] DemoFoo::HelloDemoFoo: Hello," << base::android::ConvertJavaStringToUTF8(env, who); 17 | } 18 | 19 | static jlong JNI_DemoFoo_Init(JNIEnv* env, const base::android::JavaParamRef& caller) { 20 | DLOG(INFO) << "[demo_apk]================ JNI_DemoFoo_Init"; 21 | j_demo_foo.Reset(caller); 22 | return reinterpret_cast(new DemoFoo()); 23 | } 24 | 25 | static void JNI_DemoFoo_Hello(JNIEnv* env, const base::android::JavaParamRef& who) { 26 | LOG(INFO)<<"[demo_foo] JNI_DemoFoo_Hello: Hello,"< 5 | 6 | #include "base/android/jni_android.h" 7 | #include "base/android/scoped_java_ref.h" 8 | 9 | namespace demo_jni { 10 | 11 | class DemoFoo { 12 | public: 13 | void HelloDemoFoo(JNIEnv* env, const base::android::JavaParamRef& who); 14 | }; 15 | 16 | void Hi(std::string who); 17 | void HiStatic(std::string who); 18 | } 19 | 20 | #endif //DEMO_DEMO_ANDROID_DEMO_FOO_H -------------------------------------------------------------------------------- /demo_android/demo_apk/res/layout/demo_apk_activity.xml: -------------------------------------------------------------------------------- 1 | 2 | 3 | 8 | 11 | 16 | 25 | 26 | -------------------------------------------------------------------------------- /demo_android/demo_apk/res/mipmap-hdpi/app_icon.png: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/keyou/chromium_demo/489185ebad7deb2a3155e1d4abdfdf8bf62eb0bd/demo_android/demo_apk/res/mipmap-hdpi/app_icon.png -------------------------------------------------------------------------------- /demo_android/demo_apk/res/values/strings.xml: -------------------------------------------------------------------------------- 1 | 2 | 3 | Hello,DemoApk! 4 | -------------------------------------------------------------------------------- /demo_android/demo_apk/src/org/chromium/demo_apk/DemoApkActivity.java: -------------------------------------------------------------------------------- 1 | // Copyright 2012 The Chromium Authors.

-------------------------------------------------------------------------------- /demo_mojo/README.md: -------------------------------------------------------------------------------- 1 | # demo_mojo 2 | 3 | 该目录中的 demo 用来演示 chromium 中的 IPC 组件 `mojo`。 它是 chromium 多进程架构依赖的基础组件，因此非常重要。关于它的详细介绍可以参考官方文档或者我的 [Blog](https://keyou.github.io/blog/2020/01/03/Chromium-Mojo&IPC/)。 4 | 5 | 需要注意的是，这里演示的是 mojo 本身的接口及其使用方法，这些接口不依赖于任何的 chromium 核心逻辑，因此在 chromium 中看起来可能不太一样，原因是 chromium 对一些接口进行了更多的包装。 6 | 7 | 该目录包含以下几个 demo： 8 | - demo_mojo_single_process: 演示在单进程中使用 mojo 的 C 接口； 9 | - demo_mojo_multiple_process: 演示在多进程使用 mojo 的 C 接口； 10 | - demo_mojo_multiple_process_binding: 演示在多进程中使用 mojo 的 C++ 接口； 11 | - demo_services: （**DEPRECATED**）演示在多进程中使用 service 机制；

demo_mojo_v8 2 | 3 | 这个 demo 主要演示了如何使用运行在 render 进程中的 js 代码，调用 browser 中的 mojo 接口。 4 | 5 | 如果希望用在 content_shell 中，只需要把下边的注入点替换到 content_shell 对应位置即可。 6 | 7 | 这里主要用到了 mojo 与 v8 相关知识。 8 | 9 | TODO: [PR

browser 通过自定义 mojo 接口进行通信。 20 | 21 | ## 使用方式 22 | 23 | 首先确保 `src` 仓库的分支为 `91.0.4472.*`，然后进入 `src` 目录下，使用以下命令应用 0002 号 patch `demo/patches/0002-demo_mojo_v8.patch`： 24 | 25 | ```sh 26 | git apply demo/patches/0002-demo_mojo_v8.patch 27 | ``` 28 | 29 | 然后编译 chrome： 30 | 31 | ```sh 32 | autoninja -C out/Default chrome 33 | ``` 34 | 35 | 最后使用使用编译好的 chrome 打开 `demo/demo_mojo_v8/test/index.html` 文件，观察页面控制台即可看到运行结果。 36 | -------------------------------------------------------------------------------- /demo_mojo_v8/browser/demo_impl.cc:

初始化Content模块（和Browser进程） 16 | 17 | content 通过被 services 模块启动。 18 | 19 | content实现了services 模块提供的接口，并且在 content::ContentMain() 中启动（services模块提供的） service_manager::Main() ,在这个函数中进行一些通用的初始化工作，最后（将content作为services的embedder）启动由content实现的RunEmbedderProcess()方法，至此servcies模块将控制权完全转移到content模块的ContentMainRunner。 20 | 21 | ContentMainRunner会启动ServiceManager，最后通过调用BrowserMain()将控制权转移到browser子模块。 22 | 23 | BrowserMain()通过BrowserMainRunner继续启动，BrowserMainRunner包装了BrowserMainLoop，BrowserMainLoop的主要功能包括： 24 | 25 | 1. 调用BrowserMainParts，以便允许用户的逻辑被执行； 26 | 1. 调用content::BrowserStartupComplete()，以便通知Android初始化完成； 27 | 1. 初始化主线程； 28 | 1. 创建IO线程； 29 | 1. 初始化Mojo; 30 | 1. 初始化音视频/麦克风/触摸屏等设备； 31 | 1. 初始化WebRTC; 32 | 1. 初始化剪切板相关服务； 33 | 1. 根据需求启动GPU进程； 34 | 1. 启动主线程的消息循环； 35 | 36 | BrowserMainParts作为Browser初始化的末端，用户在这里进行扩展，插入创建UI的逻辑。 37 | 38 | ``` 39 | #0 content/public/browser/browser_main_parts.cc:*() 40 | #1 content/browser/browser_main_loop.cc:*() 41 | #2 content/browser/browser_main_runner_impl.cc:*() 42 | #3 content/browser/browser_main.cc:43:BrowserMain() 43 | #4 content/app/content_main_runner_impl.cc529:RunBrowserProcessMain() 44 | #5 content/app/content_main_runner_impl.cc:978:RunServiceManager() 45 | #6 content/app/content_main_runner_impl.cc:878:Run() 46 | #7 content/app/content_service_manager_main_delegate.cc:52:RunEmbedderProcess() 47 | ``` 48 | 49 | 综上，Browser进程的初始化流程如下： 50 | content::ContentMain()->service_manager::Main()->SerivceManagerMainDelegate->ContentMainRunner->content::BrowserMain()->BrowserMainRunner->BrowserMainLoop->BrowserMainParts->(创建UI) 51 | 52 | ## 创建GPU进程 53 | 54 | TODO 55 | 56 | ## 创建UI 57 | 58 | Browser初始化完成之后，会在BrowserMainParts中创建UI。 59 | 60 | > 注意：并不是一定要在这里创建UI，因为创建UI是一个相对独立的过程，可以放在任何业务觉得合适的时机，比如放在用户打开某一个网页的时候再创建。 61 | 62 | 创建UI可以分为以下几步： 63 | 64 | 1. 创建Native窗口； 65 | 2. 创建WebContents，并将WebContents和Native窗口关联； 66 | 67 | 初始化OutputSurface 68 | 69 | ContentViewRenderView 用来显示网页内容，它内部维护了一个SurfaceView/TextureView，并且将他们的Surface传递到Native层，Native层使用它们创建OutputSurface，并且在该OutputSurface上绘制网页内容。 70 | 71 | TODO 72 | 73 | ## 创建Render进程 74 | 75 | Render进程并不会一开始就创建，而是在要打开某一个网页的时候才创建。 76 | 77 | Render进程的启动流程如下： 78 | WebContents->NavigationController->NavigationRequest->RenderFrameHostManager->SiteInstance->RenderProcessHost::Init()->ChildProcessLauncher 79 | 80 | 由于RenderProcess是按需启动的，因此它的启动流程比较复杂。 81 | 82 | TODO 83 | -------------------------------------------------------------------------------- /docs/ui.md: -------------------------------------------------------------------------------- 1 | # UI 2 | 3 | UI 分两部分，一部分是窗口，一部分是控件。 4 | 5 | chromium 中对窗口的包装包括： 6 | 7 | - aura 8 | - PlatformWindow 9 | - X11/Ozone/Windows 10 | 11 | chromium 中对UI控件的包装包括: 12 | 13 | - views 14 | - cc 15 | - viz 16 | 17 | chromium 中对渲染的包装包括: 18 | 19 | - skia 20 | - command buffer 21 | - angle 22 | - egl/opengl(es) 23 | 24 | TODO: 完善文档 25 | 26 | > views 和 WebContents 相关类图见： 27 | -------------------------------------------------------------------------------- /patches/0001-demo_viz_layer_offscreen-add-GetOffscreenTextureId.patch: -------------------------------------------------------------------------------- 1 | From dcf992dac28c1d35803596ea8d59b6a737689ce3 Mon Sep 17 00:00:00 2001 2 | From: keyou 3 | Date: Sat, 1 Aug 2020 11:06:30 +0800 4 | Subject: [PATCH] demo_viz_layer_offscreen: add GetOffscreenTextureId 5 | 6 | --- 7 | .../viz/service/display/skia_output_surface.h | 3 +++ 8 | .../skia_output_device_offscreen.cc | 16 +++++++++++++++- 9 | 2 files changed, 18 insertions(+), 1 deletion(-) 10 | 11 | diff --git a/components/viz/service/display/skia_output_surface.h b/components/viz/service/display/skia_output_surface.h 12 | index 2f06602e9c0d..d014af23bdf2 100644 13 | --- a/components/viz/service/display/skia_output_surface.h 14 | +++ b/components/viz/service/display/skia_output_surface.h 15 | @@ -41,6 +41,9 @@ namespace copy_output { 16 | struct RenderPassGeometry; 17 | } // namespace copy_output 18 | 19 | +#define VIZ_GETOFFSCREENTEXTUREID 20 | +VIZ_SERVICE_EXPORT GrGLuint GetOffscreenTextureId(); 21 | + 22 | // This class extends the OutputSurface for SkiaRenderer needs.
