Pause the background music in android

There are many examples of pausing background music on the Internet, and the most common one is pausing the music by broadcasting the pausing command. In fact, this approach is not reliable, why? Most of the time it doesn't work because other players aren't registered to listen to the broadcast.

There is a good way to manipulate the player's state by triggering a button on the media.

sendMediaButton(context,<span style="font-size:9pt;line-height:1.5;color:#2B91AF;">KeyEvent</span><span style="font-size:9pt;line-height:1.5;">.KEYCODE_MEDIA_PAUSE);</span>

private static void sendMediaButton(Context context, int keyCode) {

    KeyEvent keyEvent = new KeyEvent(KeyEvent.ACTION_DOWN, keyCode);

    Intent intent = new Intent(Intent.ACTION_MEDIA_BUTTON);

    intent.putExtra(Intent.EXTRA_KEY_EVENT, keyEvent);

    context.sendOrderedBroadcast(intent,null);

 

    keyEvent = new KeyEvent(KeyEvent.ACTION_UP, keyCode);

    intent = new Intent(Intent.ACTION_MEDIA_BUTTON);

    intent.putExtra(Intent.EXTRA_KEY_EVENT, keyEvent);

    context.sendOrderedBroadcast(intent,null);

}

Net friend realizes another kind of method

Simplify and write down the process

{
 private Visualizer visualizer = null;// Spectrum tester 
 private byte [] mRawVizData;// Spectrum of the container 


 // instantiation  Visualizer  object 
 visualizer = new Visualizer(0); 
 mRawVizData = new byte[128];

 // Initialization of an object 
 if(visualizer != null)
 {
  if (visualizer.getEnabled()) {
    visualizer.setEnabled(false);

   }

    visualizer.setCaptureSize(mRawVizData.length);//1 It has to be in the spectrum false State use 
    visualizer.setEnabled(true);// Open spectrum acquisition 

 }

I'm just going to loop through 1 thread to get the spectrum information, and I'm just going to post it

int status = Visualizer.ERROR;

 if(visualizer != null)
 {

  // Music spectrum acquisition 
  status = visualizer.getFft(mRawVizData);// Acquisition waveform 

  if(status != Visualizer.SUCCESS)
  {
  Log.i("answer", "getWaveFail");
  }
  else
  {             
  int j = 0;

  for(int i = 0; i < 128; i++)
  {

    if(mRawVizData[i] == 0)
    {
      j++;
    }
  }

    Log.i("answer", "getWave j = " + j);
  }
 }
}
