MediaPlayer not working on some android devices

Question

I am trying to play the mp3 file from web using media player class , on some devices it is working fine but for few devices it is giving following error .

QCMediaPlayer mediaplayer NOT present Unable to create media player error (-38, 0) Attempt to call getDuration without a valid mediaplayer

any help on this will be of great help.

Answer 1

In general error -38 means you are trying to call a function in wrong state for the player.

In your case as error says, you call getDuration() when player is not prepared or started. Set setOnPreparedListener() then start the player mp.start() , then you can call getDuration() .
