adding frame animations android stack overflow error

Question

hello can anybody help me please? I've created a layout with four image buttons and a text view under each image, the image buttons used to be images at res/drawables and added to android:src="eg" and it worked perfectly, until.. i recently learnt how to create frame by frame animations (I'm still quite new to this) so i added an animation to the background of the image buttons (removed android:src="eg") and used touchevent from android developer tutorials but later changed that so the image ran on start, and it worked beautifully so i wanted the other image buttons to follow suit. I'm using a .xml animation list and I've added each animation one at a time i added the second and it also ran fine but adding the third gives me a stack over flow error, i read here it could be because of nested viewgroups but changing the xml to display the animated imagebuttons accomplishes nothing, I've also tried taking all other code out and aggressively scaling back my images to no avail and trying to interpret my logcat leads me to believe its a java issue so im listing my logcat, xml layout, drawable xml (animationlist) and java file, thank you for any and all help.

Answer 1

The only thing I can think of is that you're recursively referencing the same drawable XML here: <item android:drawable="@drawable/movingdogmoves" android:duration="150"/> .

Is this inside the movingdogmoves.xml? That would cause a stack overflow
