BroadcastReceiver requires android.permission.RECEIVE_BOOT_COMPLETED -


my android app needs notified boot_completed event. androidmanifest.xml contains <uses-permission android:name="android.permission.receive_boot_completed" /> , inside <application> tag have following receiver definition:

<receiver android:name=".onbootreceiver"            android:permission="android.permission.receive_boot_completed">     <intent-filter>         <action android:name="android.intent.action.boot_completed" />     </intent-filter> </receiver>

is android:permission="android.permission.receive_boot_completed" required? happens if not in place, there risk of application being able simulate boot event , invoking app?

in examples, the receiver contains receive_boot_completed permission , some receiver not. there api level specific differences?

is android:permission="android.permission.receive_boot_completed" required?

no, don't require permission attribute inside <receiver> declaration particular case. docs:

android:permission

the name of permission broadcasters must have send message broadcast receiver. if attribute not set, permission set <application> element's permission attribute applies broadcast receiver. if neither attribute set, receiver not protected permission.

so need attribute if want make sure broadcasters authorized permission can send it. however, boot_completed protected intent can sent system anyway. wouldn't hurt have there not necessary.

edit:

it probably wouldn't hurt leave permission attribute there many android versions , device changes out there, not include attribute sure. don't include in apps.
