有没有人知道为什么会被抛出？这是我的视频和XML

public class OpenByApiActivity extends Activity implements Callback { 


MediaPlayer mp = new MediaPlayer(); 
@Override 
public void onCreate(Bundle savedInstanceState) { 
super.onCreate(savedInstanceState); 
requestWindowFeature(Window.FEATURE_NO_TITLE); 
setContentView(R.layout.video); 
StringBuilder log = new StringBuilder(); 
    String[] clearLogcat = new String[] { "logcat", "-c",}; 
    try { 
     Runtime.getRuntime().exec(clearLogcat); 
    } 
    catch (IOException e) { 
     e.printStackTrace(); 
    } 
       File location = new File("/sdcard/MediaTestFiles/sample.mp4"); 
    Uri path = Uri.fromFile(location);  
    SurfaceView surfaceView; 
    SurfaceHolder surfaceHolder; 
    getWindow().setFormat(PixelFormat.UNKNOWN); 
    surfaceView = (SurfaceView)findViewById(R.id.surfaceview); 
    surfaceHolder = surfaceView.getHolder(); 
    surfaceHolder.addCallback(this); 
    surfaceHolder.setFixedSize(176, 144); 
    surfaceHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS); 
    mp.setAudioStreamType(AudioManager.STREAM_MUSIC); 
    mp.setDisplay(surfaceHolder); 
    mp= MediaPlayer.create(this, path);   
    if(mp!=null){ 
    mp.start(); 
        }}} 
       @Override 
public void surfaceChanged(SurfaceHolder arg0, int arg1, int arg2, int arg3) {

} 

@Override

@Override

Answer 1

代码，你可以试试这个，告诉我，如果你仍然有同样的问题

final File location = new File(Environment.getExternalStorageDirectory(), "/MediaTestFiles/sample.mp4"); 

我想这个问题可能是您的路径。

UPDATE

你能移动此行

@Override 
public void surfaceCreated(SurfaceHolder arg0) { 
    //mp.setDisplay(surfaceHolder); 
    mp.setDisplay(arg0); 
} 

的onSurfaceCreated内。
