Potentially dangerous permissions

  • CALL_PHONE: Allows an application to initiate a phone call without going through the Dialer user interface for the user to confirm the call.
  • CAMERA: Required to be able to access the camera device.
  • PROCESS_OUTGOING_CALLS: Allows an application to see the number being dialed during an outgoing call with the option to redirect the call to a different number or abort the call altogether.
  • READ_CONTACTS: Allows an application to read the user's contacts data.
  • READ_EXTERNAL_STORAGE: Allows an application to read from external storage.
  • READ_PHONE_STATE: Allows read only access to phone state, including the phone number of the device, current cellular network information, the status of any ongoing calls, and a list of any PhoneAccounts registered on the device.
  • RECORD_AUDIO: Allows an application to record audio.
  • WRITE_CONTACTS: Allows an application to write the user's contacts data.

Other permissions

  • SYSTEM_ALERT_WINDOW: Allows an app to create windows using the type TYPE_SYSTEM_ALERT, shown on top of all other apps. Very few apps should use this permission; these windows are intended for system-level interaction with the user.
