The problem probably is happening because you are not stoping the media player that you create in your Songs_Single activity, then when you go to main activity, you are creating another Media Player instance and playing another song, it will play both media player simultaneously.

To solve this problem you have to use the same MediaPlayer to manage your songs in background, you can use a Servive or Intent Service to do it.

For work with services please read this answer

i want to song continue playing until i hit the play button for the second song – mahdi azarm Dec 10 '15 at 18:08
You just need to `stop()` and `release()` your `MediaPlayer` that was playing the song, then you start your media player with the new song, `mediaPlayer.setDataSource(newsong); ` `mediaPlayer.prepare();` – diogojme Dec 10 '15 at 18:16
Make sure you was stopped the MediaPlayer instance that you create to play the first song, also considers you have the access to that media player from the main activity. – diogojme Dec 10 '15 at 18:22
tnx but i'm pretty new in android and i don't know a lot about service in android. i have to create a new class called BackgroundSoundService or just change my Songs_Single class as it said in that answer? – mahdi azarm Dec 10 '15 at 18:27
Yes, you have to create a Service separate then inside of the service you put your Media Player and methods that manage your songs. Please read about services and check the link i put in the answer, there have a example to how do a media player using service, and you can take a look here http://stackoverflow.com/a/21223481/1879661 to how you connect your activity to your service. Also considers the best and the right way using service to manage songs in the background. – diogojme Dec 10 '15 at 18:36
tnx a lot for your help it's work perfect.but it show stop and wait window after first start what is the problem? – mahdi azarm Dec 10 '15 at 19:16
how can i make it cache songs and play it from memory at the second time instead of load it from url again? – mahdi azarm Dec 10 '15 at 19:35

Service run in the UI Thread , if you are doing a lot of work in the service probably your app will show this popup, create and add this hard work inside a Thread or AsyncTask in your service. Learn about the concepts of Background Services. http://developer.android.com/training/run-background-service/index.html – diogojme Dec 10 '15 at 19:43
tnx i added mediaPlayer.setDataSource() and player.prepare() to the service on create method is it the problem? and if it is how can i add it from outside? – mahdi azarm Dec 10 '15 at 19:50

Yes, thats the problem, both have to be in a method outside of the onCreate and you have to call this method using an instance of the service in your activity. When you press the button play you access this method by this service instance in the activity. – diogojme Dec 10 '15 at 19:55

mp is your mediaplayer.

if (mp != null) {
    mp.stop();
    mp.release();
    mp = null;
}
