(I'm new at this, any help, or even wild guesses, would be appreciated) I'm using Daneshm90's (very awesome) APK Manager to mess around with my framework-res.apk file. I've sucessfully reskinned some pngs and changed some xml files and stuff like that. But any time I try to add a file to framework-res I get a bootloop. So why does the following cause a bootloop? 1) Decompile Framework-res.apk 2) Make a copy of res\drawable\btn_default_small.xml and rename it btn_default_small2.xml 3) Change the background of something to android:background="@drawable/btn_default_small2" 4) Compile\flash to phone etc, watch it bootloop I can edit existing files just fine, but whenever I try to add and use a new file everything grinds to a halt, even if its just a copy of a working 'stock' file. What am I missing? Is there a list of files somewhere I need to add my new xml file to? Should I be building from source instead of using apk manager?
