I’ve been making an attempt to commencement a work once a instrumentality boots ahead connected android, however I can not acquire it to activity. I’ve appeared astatine a figure of hyperlinks on-line however no of the codification plant. Americium I forgetting thing?

AndroidManifest.xml

<receiver android:sanction=".StartServiceAtBootReceiver" android:enabled="actual" android:exported="mendacious" android:description="StartServiceAtBootReceiver" > <intent-filter> <act android:sanction="android.intent.act._BOOT_COMPLETED" /> </intent-filter> </receiver> <work android:sanction="com.trial.RunService" android:enabled="actual" /> 

BroadcastReceiver

national void onReceive(Discourse discourse, Intent intent) { if ("android.intent.act.BOOT_COMPLETED".equals(intent.getAction())) { Intent serviceLauncher = fresh Intent(discourse, RunService.people); discourse.startService(serviceLauncher); Log.v("Trial", "Work loaded astatine commencement"); } } 

The another solutions expression bully, however I idea I’d wrapper all the pieces ahead into 1 absolute reply.

You demand the pursuing successful your AndroidManifest.xml record:

1. Successful your <manifest> component:

   <makes use of-approval android:sanction="android.approval.RECEIVE_BOOT_COMPLETED" /> 
   

2. Successful your <exertion> component (beryllium certain to usage a full-certified [oregon comparative] people sanction for your BroadcastReceiver):
