问题
I have to update app which is present under /system/priv-app/ using adb install -r "APK path ".After installation version name is changing to latest in setting app.but once i open app first time it crashes and then runs with old code.I added only one line log in new version, result was same app crashed with ResourceNotFound Exception.
After long struggle i tried rebooting phone then it is working fine.One more thing I would like to add is previous app was built on Eclipse and update is built on Android studio.
Attached logs-
