Apps Frame Animation - Too many frames?

[Pabrick]

Hi,

I'm making an app with several animations, with 480x320 PNG Frames.

I've got a XML for each animation.

Then I call each animation this way:
capa_sangre.setBackgroundResource(R.anim.sangcorta);
anim_sangre = (AnimationDrawable) capa_sangre.getBackground();
anim_sangre.start();

The problems is that if the animation has more than 5 frame my app close itself.

not sure but maybe something to do with setting the bg drawable instead of the source?

just a wild guess though
