【Android】基于SurfaceControlViewHost实现跨进程渲染

1 前言

​    本文将介绍基于 SurfaceControlViewHost 实现跨进程渲染普通 View 和 GlSurfaceView，力求用最简单的 Demo，介绍 SurfaceControlViewHost 的应用，方便读者轻松扣出核心代码应用到自己的业务中。
​    核心代码片段如下。
​    1）服务端

1. public SurfaceControlViewHost.SurfacePackage getSurfacePackage(int displayId, IBinder hostToken, int width, int height) {
2.     // 创建SurfaceControlViewHost
3.     Display display = mContext.getSystemService(DisplayManager.class).getDisplay(displayId);
4.     mSurfaceControlViewHost = new SurfaceControlViewHost(mContext, display, hostToken);
5.     // 创建要渲染的View
6.     mView = new CustomView(mContext);
7.     // 将View附加到SurfaceControlViewHost
8.     mSurfaceControlViewHost.setView(mView, width, height);
9.     SurfacePackage surfacePackage = mSurfaceControlViewHost.getSurfacePackage();
10.     return surfacePackage;
11. }

复制代码

​    2）客户端

1. IBinder hostToken = mSurfaceView.getHostToken();
2. SurfaceControlViewHost.SurfacePackage surfacePackage = mRemoteRender.getSurfacePackage(0, hostToken, 1000, 2000);
3. mSurfaceView.setChildSurfacePackage(surfacePackage);

​    本文案例项目结构如下，完整资源见 → 基于SurfaceControlViewHost实现跨进程渲染。

2 AIDL 配置

​    Android 跨进程通信可以使用 AIDL 或 messenger，它们本质都是 Binder，本文使用 AIDL 实现跨进程通信。
​    1）aidl 文件

1. // IRemoteRender.aidl
2. package com.zhyan8.remoterender;
4. import android.view.SurfaceControlViewHost.SurfacePackage;
5. import android.os.IBinder;
7. interface IRemoteRender {
8.     SurfacePackage getSurfacePackage(int displayId, IBinder hostToken, int width, int height);
9. }

复制代码

​    2）gradle 配置

1. sourceSets {
2.     main {
3. <queries>
4.     <package android:name="com.zhyan8.service" />
5.     <package android:name="com.zhyan8.glservice" />
6. </queries>aidl.srcDirs = ['src/main/aidl']
7.     }
8. }
10. buildFeatures.aidl true

复制代码

​    3）manifest 配置
​    客户端配置如下。

1. <queries>
2.     <package android:name="com.zhyan8.service" />
3.     <package android:name="com.zhyan8.glservice" />
4. </queries>

复制代码

​    服务端配置如下。

1. <queries>
2.     <package android:name="com.zhyan8.service" />
3.     <package android:name="com.zhyan8.glservice" />
4. </queries><queries>
5.     <package android:name="com.zhyan8.service" />
6.     <package android:name="com.zhyan8.glservice" />
7. </queries><queries>
8.     <package android:name="com.zhyan8.service" />
9.     <package android:name="com.zhyan8.glservice" />
10. </queries><queries>
11.     <package android:name="com.zhyan8.service" />
12.     <package android:name="com.zhyan8.glservice" />
13. </queries>
