Android: JB 4.2.2

I am trying to launch Android apps from the terminal emulator using the am command. When I tried the phone's terminal emulator application, it gave me an error:-

java.lang.SecurityException: Permission Denial: startActivity asks to run as user -2 but is calling from user 0; this requires android.permission.INTERACT_ACROSS_USERS_FULL

If I go into root mode, then the am command works. Any idea how to get am to launch browser without doing an su in the terminal emulator?

Reset to default

You just need to add the --user 0 option to your am command.

  • Hello, your solution worked perfectly. thank you very much, u see until now i was wooried that all my android apps were being launched by "am" as root. I hope that is not the case right now?

    No, that's not the case. The "user" in the command-line refers to Jelly Bean's user profiles, not to Unix user IDs. When you're using a terminal session, you need to specify which user profile the app should be running in.

  • Very interesting comment. I until now assumed that the user in terminal emulator doesn't have sufficient privileges to use am command.

I was trying to start service from terminal and i got similar output. In my case i just added qoutation marks and that helped.

su -c 'am startservice -n "com.example.app/.YourSe-rvice" -e "extra' "value"'
