android - Opengls eglCreateWindowSurface GL 错误 EGL_BAD_ALLOC

Question

在 Samsung Galaxy S6 上安装后第一次打开应用程序时出现 eglCreateWindowSurface GL Error EGL_BAD_ALLOC 并且相同的代码在其他设备上工作正常。

我试图清理内存并销毁纹理并在销毁时取消初始化所有 opengl 对象，但这对我没有帮助。

这是我的代码。

Workaround-to-losing-the-opengl-context-when-android-pauses

所以你的 Activity 的 onPause() 应该是这样的:

@Override
public void onPause() {
    eglSurface.setVisibility(View.GONE);
    super.onPause();
    ...
}

并且您将 GLSurfaceView 恢复到层次结构不是来自 onResume() 而是来自 onWindowFocusChanged() :

@Override
public void onWindowFocusChanged(boolean hasFocus) {
    super.onWindowFocusChanged(hasFocus);
    if (hasFocus && eglSurface.getVisibility() == View.GONE) {
         eglSurface.setVisibility(View.VISIBLE);
    }
    ...
}
