By mistake I have updated my older files. Is there any way to rollback those transactions. I have executed the update statement from management studio and the script does not have in Begin Trans/rollback/commit.
Switch view to Android in the left part of the Android Studio, right-click the app node, Local History , Show History . Then find the revision you want back, right click it and choose Revert . Your whole project will be reverted to this state.
Introduction. RollbackManager is a system service added in Android Q to support mainline updatability efforts. RollbackManager adds support for rolling back an APK or APEX update to the previous version installed on the device, and reverting any APK or APEX data to the state it was in at the time of install.
Currently there is no direct way with which a downgrade can be done. I managed to do the downgrade by downloading Android Studio 3.0. 1 from here and then running the installer. It will prompt whether to uninstall previous version, and when you allow and proceed, it will remove 3.1 and install 3.0.
In Android studio click to folder that you updated by mistake and open: VCS-> Local History -> Show History
It will open list of changes by time, that was done by you locally. Move to time before you made mistake, and right click on it and click Revent.
