i have a broadcast receiver which should be triggered when device is booted but it never gets triggered
when device is booted instead the whole broadcast receiver gets unregistered
.i know this has been asked multiple times before but none of the solutions seem to work

thanks in advance

edit : i am using api 19

Remove android:permission="android.permission.RECEIVE_BOOT_COMPLETED" from your <receiver> element.
