Is it possible to detect when a device enters Doze/Standby? I haven't been able to find anything in the Android documentation about a possible Broadcast Receiver or Listener that I could enable or create in order to receive notifications of these transitions.
I believe the
Intent you're looking for is
ACTION_DEVICE_IDLE_MODE_CHANGED. From the documentation:
Intent that is broadcast when the state of isDeviceIdleMode() changes. This broadcast is only sent to registered receivers.
The documentation for
isDeviceIdlemode is as follows:
Returns true if the device is currently in idle mode. This happens when a device has been sitting unused and unmoving for a sufficiently long period of time, so that it decides to go into a lower power-use state. This may involve things like turning off network access to apps. You can monitor for changes to this state with
Returns true if currently in active device idle mode, else false. This is when idle mode restrictions are being actively applied; it will return false if the device is in a long-term idle mode but currently running a maintenance window where restrictions have been lifted.
This gist is also a good read. Link is now dead.
