Android ANR

What Triggers ANR?

In Android, application responsiveness is monitored by the Activity Manager and Window Manager system services. Android will display the ANR dialog for a particular application when it detects one of the following conditions:

  • No response to an input event (e.g. key press, screen touch) within 5 seconds
  • A BroadcastReceiver hasn't finished executing within 10 seconds
