How to Automatically Uninstall Android App from Device Before Installing a New Version

How do I uninstall and re-run an app on a device using Android Studio?

You can skip the force stop and uninstall step by just hitting run again. Android Studio should prompt you which device to run on and there you can select your connected device.

It will close the app and re-run your changed version.

Apparently, if you in Run -> Edit Configurations..., on the left side there is a expendable list of Android configurations.

Select yours, on the right side of the window are details on the configuration, at the bottom of that section is the Before launch section.

Create a gradle-aware Make, given the task :app:uninstallAll or :app:uninstallDebug whichever suits you. (There is autocompletion to get all the available tasks, app may vary if you have several modules).

Require users to uninstall previous Android app version on update

As far as I know, there is no way to do exactly what you asked for. But, if there are only database changes, you can just rename the database file to make your application to start using a new database file and ignore the old one.

Example:

// in your DatabaseHelper constructor
private DatabaseHelper(Context context) {
  super(context, "new_database.db", null, DB_VERSION);
}
