I have a widget to turn data connection on and off. Since I upgraded my Nexus 4 to Lollipop, I get the message
"widgetsoid needs to be installed as a system app"
So I rooted the phone, moved the apk file from
/system/app. I set the permission to 644. Rebooted the phone.
Still, I get the the same error message. Do I have to uninstall the app, and reinstall it from the apk?
What am I doing wrong? I use a custom launcher, if that matters.
