重复跑了2万次，出现了crash异常

[ThisZhu]

我封装了一个mx播放器，底层用的是ijkplayer，本质是这样的： mx调用start（）方法时动态创建textureview，并且用addview方法添加到根布局中，mx调用stop（）方法时将textureview从根布局中移除。在onSurfaceTextureAvailable中创建并准备ijkplayer播放器，在onSurfaceTextureDestroyed中停止并销毁ijkplayer播放器。

我在在一个无限循环中 创建mx播放器，用mx播放一个本地视频20s，然后停止播放并销毁mx，期间mx可能在前台也可能是在后台运行。我这样循环了2万多次，直到出现下面的异常。

日志如下： Thread Name:Thread[main,5,main] java.lang.IllegalStateException at tv.danmaku.ijk.media.player.IjkMediaPlayer._prepareAsync(Native Method) at tv.danmaku.ijk.media.player.IjkMediaPlayer.prepareAsync(IjkMediaPlayer.java:515) at com.createled.cxsx.dsapp.player.manager.IjkPlayerManager.onViewAvailable(IjkPlayerManager.java:313) at com.createled.cxsx.dsapp.player.controller.MediaControl.onSurfaceTextureAvailable(MediaControl.java:307) at android.view.TextureView.getHardwareLayer(TextureView.java:368) at android.view.View.updateDisplayListIfDirty(View.java:15157) at android.view.View.draw(View.java:15954) at android.view.ViewGroup.drawChild(ViewGroup.java:3609) at android.view.ViewGroup.dispatchDraw(ViewGroup.java:3399) at android.view.View.draw(View.java:16187) at android.view.View.updateDisplayListIfDirty(View.java:15180) at android.view.View.draw(View.java:15954) at android.view.ViewGroup.drawChild(ViewGroup.java:3609) at android.view.ViewGroup.dispatchDraw(ViewGroup.java:3399) at android.view.View.updateDisplayListIfDirty(View.java:15175) at android.view.View.draw(View.java:15954) at android.view.ViewGroup.drawChild(ViewGroup.java:3609) at android.view.ViewGroup.dispatchDraw(ViewGroup.java:3399) at android.view.View.updateDisplayListIfDirty(View.java:15175) at android.view.View.draw(View.java:15954) at android.view.ViewGroup.drawChild(ViewGroup.java:3609) at android.view.ViewGroup.dispatchDraw(ViewGroup.java:3399) at android.view.View.updateDisplayListIfDirty(View.java:15175) at android.view.View.draw(View.java:15954) at android.view.ViewGroup.drawChild(ViewGroup.java:3609) at android.view.ViewGroup.dispatchDraw(ViewGroup.java:3399) at android.view.View.updateDisplayListIfDirty(View.java:15175) at android.view.View.draw(View.java:15954) at android.view.ViewGroup.drawChild(ViewGroup.java:3609) at android.view.ViewGroup.dispatchDraw(ViewGroup.java:3399) at android.view.View.draw(View.java:16187) at com.android.internal.policy.PhoneWindow$DecorView.draw(PhoneWindow.java:2690) at android.view.View.updateDisplayListIfDirty(View.java:15180) at android.view.ThreadedRenderer.updateViewTreeDisplayList(ThreadedRenderer.java:281) at android.view.ThreadedRenderer.updateRootDisplayList(ThreadedRenderer.java:287) at android.view.ThreadedRenderer.draw(ThreadedRenderer.java:322) at android.view.ViewRootImpl.draw(ViewRootImpl.java:2623) at android.view.ViewRootImpl.performDraw(ViewRootImpl.java:2442) at android.view.ViewRootImpl.performTraversals(ViewRootImpl.java:2075) at android.view.ViewRootImpl.doTraversal(ViewRootImpl.java:1115) at android.view.ViewRootImpl$TraversalRunnable.run(ViewRootImpl.java:6023) at android.view.Choreographer$CallbackRecord.run(Choreographer.java:858) at android.view.Choreographer.doCallbacks(Choreographer.java:670) at android.view.Choreographer.doFrame(Choreographer.java:606) at android.view.Choreographer$FrameDisplayEventReceiver.run(Choreographer.java:844) at android.os.Handler.handleCallback(Handler.java:739) at android.os.Handler.dispatchMessage(Handler.java:95) at android.os.Looper.loop(Looper.java:148) at android.app.ActivityThread.main(ActivityThread.java:5422) at java.lang.reflect.Method.invoke(Native Method) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:726) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:616)

这是我的部分代码： public void onSurfaceTextureAvailable(SurfaceTexture surfaceTexture, int width, int height）{

    surface = new Surface(surfaceTexture);

    init();

    if (ijkMediaPlayer != null) {
        ijkMediaPlayer.setSurface(surface);
        ijkMediaPlayer.prepareAsync();

    }

}

public boolean onSurfaceTextureDestroyed(SurfaceTexture surface) {

    this.surface=null;

    if(ijkMediaPlayer!=null) {
        ijkMediaPlayer.setSurface(null);
        ijkMediaPlayer.pause();
        ijkMediaPlayer.stop();
        ijkMediaPlayer.release();
        ijkMediaPlayer=null;
    }

    return false;

}

private void init(){

   ijkMediaPlayer=new IjkMediaPlayer();

   ijkMediaPlayer.setLooping(true);

   ijkMediaPlayer.setDataSource(context, Uri.fromFile(file));

   ijkMediaPlayer.setOnPreparedListener(new IMediaPlayer.OnPreparedListener() {
        @Override
        public void onPrepared(IMediaPlayer iMediaPlayer) {
            ijkMediaPlayer.start();
            LogUtil.v(TAG,"ijkPlayer  started!");
        }
    });

}

public void start(){ textureView=ViewFactory.getInstance().creViewFromOtherLayout();

  textureView.setSurfaceTextureListener(this);

}

public void stop() {

 if(ijkMediaPlayer!=null) {

        this.surface=null;
        ijkMediaPlayer.setSurface(null);
        ijkMediaPlayer.pause();
        ijkMediaPlayer.stop();
        ijkMediaPlayer.release();
    }

 ViewFactory.getInstance().removeView(textureView);

}

补充下，我是开启了硬解的，运行的设备也是支持的

setLooping(true)能循环播放视频吗?我这不生效,只播放一次
