My Activities are randomly crashing due to Resource$NotFoundException and it's always due to one of my custom button's state selector files. And the crashes are completely random, I'll go through the entire app multiple times with no crashes, and then go to an Activity for the nth time, and then it'll throw the exception.
Stack Trace:

07-12 11:12:18.515 1235 1235 W ActivityManager: Force finishing activity com.appname.droid/.send.ConfirmActivity
And line 40 in ConfirmActivity is the piece of code:
setContentView(R.layout.confirm);
And here is res/drawable/btn_green.xml
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:state_enabled="false"
android:drawable="@drawable/green_large_btn_pressed" />
<item
android:state_pressed="true"
android:state_enabled="true"
android:drawable="@drawable/green_large_btn_pressed" />
<item
android:state_focused="true"
android:state_enabled="true"
android:drawable="@drawable/green_large_btn" />
<item
android:state_enabled="true"
android:drawable="@drawable/green_large_btn" />
</selector>
This exception occurs throughout the app and it's always one of my buttons. The same thing happens with my btn_gray and btn_orange.
color_large_btn.png and color_large_btn_pressed.png are all present for all colors.
Android Version: Currently on a Droid2 running Android 2.2 Also happens on a Motorola Blur running Android 2.1 Doesn't seem to happen on HTC Evo running Android 2.3
This issue is essentially an out of memory scenario. After wrapping up my inflating of xml files in try-catch blocks, I was able to get passed this initial error of not being able to load in files/ find them. The resulting behavior is Activities with images just plain missing until finally an actual out of memory exception is thrown.
Fix? Found and removed numerous leaks and down sized a couple image files.
