Try using the .ogg file format for the sound files in your application. I had this same issue, and after a lot of research , i tried the .ogg format and it loops without any gaps in android.

You can easily convert your sound file from .mp3 or what have you, to .ogg using the popular open source app VLC Media Player.

Answer 3

It usually works just fine, unless you have a really slow phone.

I would double check the sound file with an audio editor like Audacity, to verify that it doesn't have any silence at the beginning or end of the file.

Answer 4

Also worth noting is that gapless playback was added with Jelly Bean (API level 16). It allows you to set a secondary mediaplayer that should be used for playing a next audio stream, as long as the primary player hasn't finished playing the current audio yet. This could potentially be used to create a gapless 'loop' too.

public void setNextMediaPlayer (MediaPlayer next)

Obviously this won't be of much help for most of the market (currently < 3% of the devices is running JB), but nevertheless worth mentioning.
