我在安装三星Galaxy S6后第一次打开应用程序时获得eglCreateWindowSurface GL Error EGL_BAD_ALLOC，同样的代码在其他设备上正常工作。
我试图清理内存并破坏纹理并在销毁时取消初始化所有opengl对象，但这无法帮助我。

我解决了OpenGL错误EGL_BAD_ALLOC
由于我没有正确处理渲染器的活动生命周期，因此发生此错误。
所以你的Activity's onPause()应该是这样的：
@Override
public void onPause() {
eglSurface.setVisibility(View.GONE);
super.onPause();
...
}
并且你将GLSurfaceView恢复到层次结构而不是来自onResume()但是来自onWindowFocusChanged()：
@Override
public void onWindowFocusChanged(boolean hasFocus) {
super.onWindowFocusChanged(hasFocus);
if (hasFocus && eglSurface.getVisibility() == View.GONE) {
eglSurface.setVisibility(View.VISIBLE);
}
...
}
