Alright, first with the goods:
- Doesn't force close (Droid X2)
- Layout looks relatively thought out (in portrait mode)
Now, for some suggestions (From developer to new developer)
- Add an option to disable sound
- have your quotes scroll from left to right in, instead of fade (see below for example)
- Make a landscape layout (this is very important, it looks very poor in landscape mode, look up how to flip emulator to landscape)
- override the vol up/down buttons on the phone, allow so whenever pressed it changes media volume
- when you flip between landscape and portrait you dont keep where in the array you are, pass this number so you dont restart at first quote every time you flip orientation
Now, quick example for the animation (need to keep you on your feet for the rest, cant do it all for you

)
here is the code for sliding the old quote out (from right to left where left is no longer on the screen)
exit_slide_left_right.xml
Code:
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:shareInterpolator="false">
<translate
android:fromXDelta="0%" android:toXDelta="100%"
android:fromYDelta="0%" android:toYDelta="0%"
android:duration="700" />
</set>
now here is for sliding new one in, where start is not on screen (off to right) to middle of screen where quote is (at the end of animation)
enter_slide_left_right.xml
Code:
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:shareInterpolator="false">
<translate android:fromXDelta="0%" android:toXDelta="-100%"
android:fromYDelta="0%" android:toYDelta="0%"
android:duration="700"/>
</set>
these go in the anim folder, you do however need to do some research on how to use these!
Good luck!
