Android - SurfaceView 中的奇怪崩溃

编程问答 2022-05-03

问题描述

我在 Firebase 中遇到了这些奇怪的异常（我假设它们是同一回事），但我无法调试它。即使我与获得它的用户之一拥有相同的设备，它也从未发生在我身上。此外，我似乎无法在 requestTransparentRegion 或 GlSurfaceView 的源代码中找到方法 SurfaceView。

有帮助解决这个问题吗？

我的 GlSurfaceView 子类

public class MyGlSurfaceView extends GLSurfaceView {

    public MyRenderer myRenderer;

    public MyGlSurfaceView(Context context){
        super(context);
        init(context);
    }

    public MyGlSurfaceView(Context context,AttributeSet set){
        super(context,set);
        init(context);
    }

    void init(Context context){
        setPreserveEGLContextOnPause(true);
        setZOrderOnTop(true);
        setEGLConfigChooser(8,8,16,0);
        getHolder().setFormat(PixelFormat.RGBA_8888);

        setEGLContextClientVersion(2);
        myRenderer = new MyRenderer(this);
        setRenderer(myRenderer);
        setRenderMode(GLSurfaceView.RENDERMODE_CONTINUOUSLY);

    }

}
