I'm learning to use the Backup API to backup/restore app data. Then I used bmgr tools to test it and met the following problem.

I typed these commands as below in cmd:

**adb shell bmgr backup com.example.myapp**   ---------------OK
**adb shell bmgr run**                        ---------------Ok

then I enter the settings -> app to clean the data of this app. I continue to type:

**adb shell bmgr restore com.example.myapp**  ---------------Ok

This seems to work fine. But when I uninstall the app and re-install it, nothing happens. There no data is restored automatically.

And when I use adb shell bmgr restore com.example.myapp to force the restoring, I met this response : unable to restore package com.example.myapp.

My env:

  • Emulator: Google API16
  • the Google account has been set
  • check auto backup

Has anyone met this problem ? How should I solve it ?
