Re: [android-beginners] Application crashing
Hi,
Your onCreate method is not calling the default:
super.onCreate( icicle );
Also, I would wrap the body of the code in a try{ } catch( Exception ex
) clause.
Hope this helps,
Sy

[android-beginners] Re: Android application not playing sound on phone
Its odd, but one of the MP3 files will play the other just sounds like a
blip, both files sound fine on the PC.
Here is the modified play routine:
private void playSound(int dResource) {
try{
if ( m_objMediaPlayer != null ) {
m_objMediaPlayer.stop();
m_objMediaPlayer.release();
}
m_objMediaPlayer = MediaPlayer.create(getBaseContext(),
dResource);
m_objMediaPlayer.setLooping(false);
m_objMediaPlayer.seekTo(0);
//m_objMediaPlayer.prepareAsync();
m_objMediaPlayer.start();
} catch( Exception ex ) {
Log.e( RacingLights.playSound, , ex );
}
}

Hi,
I have been developing my first Android application which so far works
just fine on the emulator and everything apart from the sounds also
works on the phone.
I have a HTC Tattoo phone and my application is being developed for
Android 1.6.
I have two small MP3 files in my resources:
raw
on.mp3 (3.28kb)
off.mp3 (1.24Kb)
When I try the application on the phone I don't get any sound effects,
here is the code that works on the emulator:
private void playSound(int dResource) {
try{
if ( m_objMediaPlayer != null ) {
m_objMediaPlayer.stop();
m_objMediaPlayer = null;
}
m_objMediaPlayer = MediaPlayer.create(this, dResource);
m_objMediaPlayer.setLooping(false);
m_objMediaPlayer.start();
} catch( Exception ex ) {
Log.e( playSound, , ex );
}
}
Thank you.

Re: [android-beginners] Re: Android application not playing sound on phone
Hi,
Thank you for the reply, both files play on a PC, but only one will play on
the phone.

sometimes you find encoding problems with MP3s, as in they don't use a
standard encoding..not sure what codecs Android supports but maybe
just try and play the file normally through the media player and see
if it works
