MediaPlayer Error (1,-2147479552), Error (-38,0)

播放视频时，采用TextureView+MediaPlayer的方案，一切都照旧。可是，在红米3s上却出现了问题。当第一个页面加载了自定义的播放器后，再打开有播放器的第二个页面时，第二个页面的播放器就不能正常播放了。提示如下错误：

MediaPlayer: Error (1,-2147479552), Error (-38,0), stop called in state 0

没道理啊，测试了其他近十几款不同牌子和型号的手机都没问题，而且红米3都没问题，但是红米3s就是不行。为何呢？开始分析日志。

查询错误：Mediaplayer start called in state 0。Stack Overflow上有给出解决办法的，就是在start()之前要调用MediaPlayer.prepraeAsync()，可是prepare已经在设置视频源时调用过了，没有解决，此方案不行。

吭哧吭哧……经过多次的测试与分析发现，对于红米3S等低配手机，当内存中存在多个TextureView时，如果在当前界面onPause()时，会调用onSurfaceTextureDestroyed()，导致下一个界面在初始化MediaPlayer绑定TextureView时出现error (1, -2147479552)的报错，因此需要在onSurfaceTextureDestroyed()时调用将MediaPlayer和Surface解除关系，在SurfaceView调用Update时再关联。另外，关于Surface的valid有些机型也表现的很诡异，按理说在onSurfaceTextureAvailable(SurfaceTexture)回调后获取Surface应该是可以立即使用的，但是有些机型就是一直提示invalid的报错，在此也一定做了兼容处理。详细解决方案见下代码：

    Surface mSurface;

    /**  
     * 标记SurfaceTexture是否销毁。对于红米3S等低配手机，在当前界面onPause()时，会调用
     * onSurfaceTextureDestroyed()，导致下一个界面在初始化MediaPlayer时出现
     * error (1, -2147479552)的报错，因此需要在onSurfaceTextureDestroyed()时调用
     * 将MediaPlayer和Surface解除关系，在SurfaceView调用Update时再关联。

        // 当Surface有效后再绑定MediaPlayer
        Observable.just(true)
                .retryUntil(() -> mSurface.isValid())
