First of all, apologies for the xpost...
Question re: weird behaviour on APK files I've edited according to http://forum.xda-developers.com/show...07&postcount=2
I use a couple of apps regularly and have tried modifying them to make the UI suit me a bit better. For what it's worth, one's a Twitter app and one's a keyboard.
I've used apktool to decompile them, edited certain res .xml files to change the interface and then compiled them again with apktool. I've then signed them using Sigare (obviously it's not signed using the original developers key, but a key that I've made)
I've then replaced the apk in data\app with my modified one.
The problem is that, while the new app works for a little white, after a while it just disappears from my app list. When I go to run it directly, I get a message that the app won't load.
TL;DR: apps I've modified work to start with and then don't. Anyone think of a reason?
