3 Implicit broadcast removed:
1: CONNECTIVITY_ACTION Action for broadcast removed:
Mobile devices experience frequent connectivity changes, such as when moving between Wi-Fi and mobile data. Currently, apps can monitor for changes in connectivity by registering a receiver for the implicitCONNECTIVITY_ACTION
broadcast in their manifest. Since many apps register to receive this broadcast, a single network switch can cause them all to wake up and process the broadcast at once.
Apps targeting Android N do not receive CONNECTIVITY_ACTION
broadcasts, even if they have manifest entries to request notification of these events. Apps running in the foreground can still listen forCONNECTIVITY_CHANGE
on their main thread if they request notification with a BroadcastReceiver
.
2: ACTION_NEW_PICTURE Action for broadcast removed:
3: ACTION_NEW_VIDEO Action for broadcast removed:
apps can register to receive implicit ACTION_NEW_PICTURE
and ACTION_NEW_VIDEO
broadcasts from other apps, such as Camera. When a user takes a picture with the Camera app, these apps wake up to process the broadcast.apps can register to receive implicit ACTION_NEW_PICTURE
and ACTION_NEW_VIDEO
broadcasts from other apps, such as Camera. When a user takes a picture with the Camera app, these apps wake up to process the broadcast.
Apps cannot send or receive ACTION_NEW_PICTURE
or ACTION_NEW_VIDEO
broadcasts. This optimization affects all apps, not only those targeting Android N.
4: Point to be taken care :
If your app uses any of these intents, you should remove dependencies on them as soon as possible so that you can target Android N devices properly. The Android framework provides several solutions to mitigate the need for these implicit broadcasts. For example, the JobScheduler
API provides a robust mechanism to schedule network operations when specified conditions, such as connection to an unmetered network, are met. You can even use JobScheduler
to react to changes to content providers.
