I set one of the program as default launcher program and default setting program so I cannot change the default programs now, can I change the default programs from android-sdk\android-sdk\platform-tools\adb.exe or remote shell.
How can I do that?
And can I remove the defaults of program in Java code?
you can remove (Uninstall) the default program you set using ADB by doing this :
adb uninstall app.package ..... //for example (com.example.homeapp)
If you don’t want to remove the app .. here is a quick hack to do it:
- adb shell
- am start -a android.intent.action.MAIN
That way you will have a picker with all apps on your devices that listens to Main Action
- Choose any home screen app you want . then go to settings and set it as default.
Answer：
For system apps you can’t uninstall, use pm disable as in
adb shell pm disable com.android.launcher
Answer：
adb shell cmd package set-home-activity “package/activity”
adb reboot
Answer：
The key is adb. Once you know the package name of the app you wish to clear data for, try:
adb shell pm clear package.name.of.app
It’ll clear all data for the app, but I don’t know of a way to only clear the defaults.
