VibrateCall depends on the permission to read Android radio log (by executing 'logcat -b radio') to determine whether a outgoing call is answered by the other side.
This permission is for Android debug or development purpose only, so a normal application downloaded from GooglePlay can never be granted this permission automatically. In order to help VibrateCall to work, you have to manually grant the permission following the steps below:
- Enable the developer options of your phone. If you don't know how to so, following the guide on this page: https://developer.android.com/studio/debug/dev-options
- Download Android SDK tools from this page: https://developer.android.com/studio , find them for different platform in section "Command Line Tools Only". Download and install it. And you can use the included SdkManager to download other SDK tools and packages
- Connect your phone with your PC with USB cable, you might see a dialog asking for confirmation to enable debugging this phone with the PC, select YES.
- On your PC, open a terminal command line shell, like cmd or powershell, execute "
adb devices" you can see the connected device listed there. If it complains about command adb is not recognized, please check your command line environment settings. - If all of above are OK, just execute the command line below:
adb shell "pm grant com.robin.huangwei.vibrate250 android.permission.READ_LOGS" - Kill this application (from application settings -> VibrateCall -> force close) or simply reboot your phone, you should get the correct permission.
- Restart this application, the permission check should be OK then.
