Pause background music in Android _android

There are many examples of suspended background music on the internet, most of which are broadcast to suspend music according to a paused instruction. In fact, this way is very unreliable, why? Because other players may not register to listen for that broadcast, most of them don't work.

Here's a more reliable way to manipulate the player state by triggering a button on the media.

Copy Code code as follows:

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>

Copy Code code as follows:

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);
}

Another way for a user to realize

Simple to write down the process

{
 Private Visualizer visualizer = null;//spectrum tester
 Private byte [] mrawvizdata;//Spectrum container


 //Instantiated Visualizer object
 Visualizer = new Visualizer (0); 
 Mrawvizdata = new byte[128];

 The initialization
 if (visualizer!= null) of an object
 {
  if (visualizer.getenabled ()) {
    visualizer.setenabled (false);

   }

    visualizer.setcapturesize (mrawvizdata.length);/Be sure to use
    visualizer.setenabled (true) in the spectral false state; Open Spectrum Access

 }

Here's a thread to loop through the spectrum, and I'll just post the fetch.

int status = Visualizer.error;

 if (visualizer!= null)
 {

  //Music spectrum get
  status = Visualizer.getfft (Mrawvizdata);//Get Waveform graph

  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);}}
