推荐答案

我找到了解决此问题的方法. 您应该简单地致电:

I found the workaround for this issue. You should simple call:

getHolder().getSurface().release();

在活动"的onDestroy()

类似这样的东西:

class MyView {

    ...

    public void release() {
        getHolder().getSurface().release();
    }

    ...
}

class MyActivity extends Activity {

    ...

    @Override
    public void onDestroy() {
         super.onDestroy();
         mMyView.release();
    }

    ...

}
