As soon as I call mp.start()I get following errorsin my LogCat:
一旦我打电话，mp.start()我的 LogCat 就会出现以下错误：

MediaPlayer player = MediaPlayer.create(this, R.raw.zindgivalaaop);
player.setVolume(50,50);
player.start();
@Override
public void onDestroy() {
super.onDestroy();
player.stop();
player.release();
}
try passing class context instead getApplicationContext()
尝试传递类上下文 getApplicationContext()

Use the code below which answered here. It'll work like a charm.
使用下面回答here的代码。它会像魅力一样发挥作用。
package com.example.hellomoon;
import android.content.Context;
import android.media.MediaPlayer;
public class AudioPlayer {
private MediaPlayer mMediaPlayer;
public void stop() {
if (mMediaPlayer != null) {
mMediaPlayer.release();
mMediaPlayer = null;
}
}
public void play(Context c, int rid) {
stop();
mMediaPlayer = MediaPlayer.create(c, rid);
mMediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
@Override
public void onCompletion(MediaPlayer mediaPlayer) {
stop();
}
});
mMediaPlayer.start();
}
}

Try this: Playing short .wav files - Android
SoundPool is the best way to play short .wav(2-3 sec.) file
SoundPool 是播放短 .wav（2-3 秒）文件的最佳方式

I think your MediaPlayer is working. Check the device 'Media volume' in settings. JNIMediaPlayerFactory: bIsQCMediaPlayerPresent 0this message comes when the device 'Media volume' set to zero.
我认为您的 MediaPlayer 正在运行。在设置中检查设备“媒体音量”。JNIMediaPlayerFactory: bIsQCMediaPlayerPresent 0当设备“媒体音量”设置为零时，会出现此消息。
