maximum number of MediaPlayer variables
<p>I'm doing a very simple app for android but I'm having a problem that I really have no idea how to solve.
My app has a layout with 8 buttons, and every button makes a sound when you click on it.
I have just one activity and within the oncreate method I define 8 MediaPlayer variables which are the 8 different sounds on mp3 format I have on my raw folder. Then I associate them to each button.
When I compile the app on the emulator, everything works fine, but when I compile it on the phone the sound 8 does not work. I mean, when I press a button which has associated the sound 8, the app crashes. I also noticed that if I add more buttons with more sounds only the first 7 sounds work, no more, the others make the app to crash. It seems like I cannot have more than seven MediaPlayer variables. But that doesn't make any sense, does it? </p>

<p>Can anyone help me to solve this??</p>

<p>Thanks in advance.</p>

<p>Here is my java code:</p>
