App not Responding While Playing media from url

Question

I have songs from json in list view, and a play button in each row , after clicking on play Button my app freezes and App not responding dialog box comes, Sometime media player started after freezing sometimes its crashes. Because of App not responsive. This is my Code :

  viewHolder.playButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                    selectedPosition = position;

                    if (selectedPosition != mPlayingPosition) {

                        try {
                            mPlayerforplanet.reset();
                            mPlayerforplanet.setAudioStreamType(AudioManager.STREAM_MUSIC);
                            mPlayerforplanet.setDataSource(song_urls);

                            logger.addRecordToLog("MediaPlayer audio session ID: " + mPlayerforplanet.getAudioSessionId());
                            logger.addRecordToLog("Media Player started " + "Started !");
                            mPlayerforplanet.prepare();
                            mPlayerforplanet.start();

                        } catch (IOException e) {
                            e.printStackTrace();
                        }
                        //  playSongs(position);(i also try with method of playsong but no luck)

                        Toast.makeText(getContext(), "play song" + mPlayingPosition, Toast.LENGTH_SHORT).show();

Answer 1

Please use prepareAsync instead of prepare and handle onPrepared and trigger start from there .

 mPlayerforplanet.prepareAsync();
 public void onPrepared(MediaPlayer mp) {
  mPlayerforplanet.start;
}

sample code :

package com.example.simplemediaplayer.app;

import android.media.AudioManager;
import android.media.MediaPlayer;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.util.Log;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.Toast;

import java.io.IOException;


public class MediaPlayerActivity extends ActionBarActivity {

    private static final String TAG = "tag";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_media_player);

        String url = "http://www.brothershouse.narod.ru/music/pepe_link_-_guitar_vibe_113_club_mix.mp3"; // your URL here
        MediaPlayer myMediaPlayer = new MediaPlayer();
        myMediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
        try {
            myMediaPlayer.setDataSource(url);
            myMediaPlayer.prepareAsync(); // might take long! (for buffering, etc)

        } catch (IOException e) {
            Toast.makeText(this, "mp3 not found", Toast.LENGTH_SHORT).show();
            e.printStackTrace();
        }

        //mp3 will be started after completion of preparing...
        myMediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {

            @Override
            public void onPrepared(MediaPlayer player) {
                player.start();
            }

        });

    }


    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.media_player, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();
        if (id == R.id.action_settings) {
            return true;
        }
        return super.onOptionsItemSelected(item);
    }
}

For seek-bar use a anew runnable :

Starting runnable ,

 public void onPrepared(MediaPlayer player) {
            mPlayerforplanet.start();
            mUpdateSeekBar.run();
        }

Code in runnable

private final Runnable mUpdateSeekBar = new Runnable() {
        @Override
        public void run() {
                   int elapsedtime = mPlayerforplanet.getCurrentPosition();
                  /* update UI with getCurrentPosition*/
                mHandler.postDelayed(mUpdateSeekBar, 1000);
        }
    };
