Android four components of the Broadcastreceiver boot

As with other broadcastreceiver, you need to configure the received broadcast information, and then configure the permissions

<receiver
Android:name= "Com.example.kaijistart.BootReceiver" >
<intent-filter >
<action android:name= "Android.intent.action.BOOT_COMPLETED"/>
</intent-filter>
</receiver>

<uses-permission android:name= "Android.permission.RECEIVE_BOOT_COMPLETED"/>

And then you can intent jump in the broadcastreceiver.

 PackageCom.example.kaijistart;ImportAndroid.content.BroadcastReceiver;ImportAndroid.content.Context;Importandroid.content.Intent; Public classBootreceiverextendsBroadcastreceiver { PublicBootreceiver () {} @Override Public voidOnReceive (Context context, Intent Intent) {Intent it=NewIntent (context,mainactivity.class); //set up a new task stack, if we go from the system diagram punctuation, the system will create the activity stack,//but we don't have to click to create a task stack by ourselves now.it.setflags (Intent.flag_activity_new_task);        Context.startactivity (IT); System.out.println ("Boot Up"); }}
