Well you have two solutions:
First:
- Open the Apk using Winrar/7zip, go to res/raw/ and extract spenboardswitcher.png to a folder.
- Rename the spenboardswitcher.png to spenboardswitcher.apk
- Use a root capable browser to move it to /system/priv-app/ (solid explorer is awesome!)
- Give it permissions of 644, and ownership of root:root
Second:
- Let the app crash
- Send me a logcat
Tried your first solution, but I have to say I don't understand that. After I did that, what now ? Its not installed that way, at least I dont find it in the App drawer after that. Thats correct right ?
Sorry, not good at these things.
