I'm having a little problem here. From months, I edited and compiled some SystemUI APKs and those APKs were fully working, but now I'm trying to use those old APKs and they are not working!! As usual, I've put the SystemUI.apk in /system/app, I've given the right permissions (RW-R-R) and rebooted the phone. The status bar has vanished!!! The strange thing is that those APKs were working before.
The APKs were not signed before, but they were working without signing them.
Okay. Can anybody help me?
