To achieve startup execution, the first thought is to use a broadcast. When the broadcast receiver receives the boot - completed broadcast, the onReceive() method is executed, and we can write the required operations in this method.
Using Android Studio to create a broadcast: Right - click the package name –> New –> BroadcastReceiver.
If you follow the above steps, the code in the red - boxed area will be automatically generated in the manifest file.
For static registration, we need to register the boot - completed broadcast in the action.
<receiver
android:name=".BootReceiver"
android:enabled="true"
android:exported="true">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED"/>
</intent-filter>
</receiver>
Also, add the permission for boot completion.
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/>
Modify the onReceive() method of the broadcast to make it pop up a notification bar after startup for easy observation.
@Override
public void onReceive(Context context, Intent intent) {
Notification.Builder builder = new Notification.Builder(context);
builder.setTicker("开机启动");
builder.setAutoCancel(true);
builder.setContentTitle("通知");
builder.setContentText("我已经开机启动了");
builder.setSmallIcon(R.mipmap.ic_launcher);
Notification notification = builder.build();
NotificationManager manager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
manager.notify(1,notification);
}
This completes the setup.
