Я пытаюсь сделать медиаплеер для воспроизведения музыки. Но после игры 3-4 песни он останавливается. И дает следующую ошибку. И я получаю ошибку именно в current = mp.getCurrentPosition(); Мой код:Android-Media player Показывает ошибку при current = mp.getCurrentPosition();
public class player extends AppCompatActivity implements View.OnClickListener {
ArrayList<File> mysong;
static MediaPlayer mp;
SeekBar sb;
int position;
Uri u;
TextView tv;
Thread updateseek;
Button btplay, btFF, btBB, btnext, btpreviout;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_player);
sb = (SeekBar) findViewById(R.id.seekBar);
btplay = (Button) findViewById(R.id.button);
btFF = (Button) findViewById(R.id.button3);
btBB = (Button) findViewById(R.id.button2);
btnext = (Button) findViewById(R.id.button5);
btpreviout = (Button) findViewById(R.id.button4);
tv = (TextView)findViewById(R.id.textView2);
tv.setVisibility(View.INVISIBLE);
btpreviout.setOnClickListener(this);
btnext.setOnClickListener(this);
btBB.setOnClickListener(this);
btFF.setOnClickListener(this);
btplay.setOnClickListener(this);
if (mp != null) {
mp.stop();
mp.release();
}
updateseek = new Thread(){
@Override
public void run() {
int total = mp.getDuration();
int current = 0;
sb.setMax(total);
while(current < total){
try {
sleep(500);
current = mp.getCurrentPosition();
sb.setProgress(current);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
super.run();
}
};
Intent i = getIntent();
Bundle b = i.getExtras();
mysong = (ArrayList) b.getParcelableArrayList("mysonglist");
position = b.getInt("pos", 0);
u = Uri.parse(mysong.get(position).toString());
mp = MediaPlayer.create(getApplicationContext(), u);
mp.setAudioStreamType(AudioManager.STREAM_MUSIC);
mp.start();
sb.setMax(mp.getDuration());
updateseek.start();
mp.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
@Override

mp.release();
}
});
