GLSurfaceView在活动被破坏后导致ANR

Question

我有一个包含GLSurfaceView的Activity。 当我点击后退按钮去上一个Activity时，它设法显示该Activity，但屏幕没有响应，最终会出现ANR。

这是onSurfaceCreated（）代码：

-编辑-

如果我移动mSurfaceView.onPause(); 对于所有者片段的onPause()然后应用程序在退出片段后不会冻结，但是在退出片段后几秒钟它通常会无声地崩溃（没有强制关闭）。

@Override
public void onSurfaceCreated(GL10 gl, EGLConfig config) {
    if (mOpenGlesVersion == OPENGLES_VERSION_10) mOpenGles = new OpenGles10();
    else if (mOpenGlesVersion == OPENGLES_VERSION_11) mOpenGles = new OpenGles11();
    else if (mOpenGlesVersion == OPENGLES_VERSION_20) mOpenGles = new OpenGles20();

    // Let the caller know the surface has been created.
    if (mListener != null) mListener.onGLSurfaceViewCreated();
    // No intention of drawing anything, just gathering info.
    mSurfaceView.onPause();
}

这是从/data/anr/traces.txt获取的日志信息:(由于--MORE--有两行被弄乱了）

您的Graphics.onSurfaceCreated()调用了GLSurfaceView.onPause() 。 你不应该调用onPause或者遇到死锁。 onPause()将调用wait()而surfaceDestroyed()将调用wait() 。

Answer 2

这是GLSurfaceView的已知错误 。 这是因为您的应用中有多个实时GLSurfaceView 。 我已经尝试了建议的修复（查看上一个链接），但最终不得不重新设计我的应用程序以手动配置GLSurfaceView实例。

我的诀窍是在GLSurfaceView的父节点上调用removeView() ，从而导致它的םnDetachedAFromView()事件被触发。

这不是最佳的，但这就是生命。

（BTW对未来Google员工的尊重 - 在我的应用程序中，罪魁祸首是ArcGIS的MapView ）。
