        secondPlayer = new MediaPlayer();

        firstPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
        secondPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);

Problem

• I am getting one Strange problem both media player not play in Sync it's having little bit different for play song.if I seek secondPlayer where firstPlayer is play then it's playing in Sync but it's not happend both player playing different.

Note

• I also try to Solve this Issue using any third party Media player but i didn't get luck.I have implement ExoPlayer,VlcPlayer,UniversalPlayer to solve this problem but It's also having same problem.

Requirement.

• I want to play song in Sync in Two different object of MediaPlayer.
• Did anyone know about any powerful media player which is not having this delay issue.

I hardly Try to solve this Sync issue but i Didn't get Luck.I want 100% Sync in My Application.Just Like Seedio app in IOS.I also test this in IOS but in IOS it's Working fine Both Player play song with 100% sync.
