Start Service at boot
Hello,
Now we are going to learn how to start a service at boot time, i.e. to start our service when device starts up.
First we have to create a BroadcastReceiver which will be started when boot completes as
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
public class MyStartupIntentReceiver extends BroadcastReceiver{
@Override
public void onReceive(Context context, Intent intent) {
}
}
onRecieve will be first called when the BroadcastReceiver MyStartupIntentReceiver starts.
Next make an entry of this receiver in AndroidManifest.xml as
<receiver android:name="MyStartupIntentReceiver"> <intent-filter> <action android:name="android.intent.action.BOOT_COMPLETED" /> <category android:name="android.intent.category.HOME" /> </intent-filter> </receiver>
Here in intent filter we have declared the action as android.intent.action.BOOT_COMPLETED , so that this receiver and intent with action android.intent.action.BOOT_COMPLETED
Now this receiver will be intimated when boot completes
Next if we want to start a service then the procedure is as follows
Create a Service as
import android.app.Service;
import android.content.Intent;
import android.os.IBinder;
import android.util.Log;
import android.widget.Toast;
public class MyService extends Service {
@Override
public IBinder onBind(Intent intent) {
return null;
}
@Override
public void onCreate() {
super.onCreate();
Toast.makeText(this, "Service Created", Toast.LENGTH_LONG).show();
}
@Override
public void onDestroy() {
super.onDestroy();
Toast.makeText(this, "Service Destroyed", Toast.LENGTH_LONG).show();
}
@Override
public void onStart(Intent intent, int startId) {
super.onStart(intent, startId);
Toast.makeText(this, "Service Started", Toast.LENGTH_LONG).show();
}
}
Make an entry of this service in AndroidManifest.xml as
<service android:name="MyService"> <intent-filter> <action android:name="com.wissen.startatboot.MyService" /> </intent-filter> </service>
Now start this service in the BroadcastReceiver MyStartupIntentReceiver’s onReceive method as
public void onReceive(Context context, Intent intent) {
Intent serviceIntent = new Intent();
serviceIntent.setAction("com.wissen.startatboot.MyService");
context.startService(serviceIntent);
}
Next you can write the code that you want to execute when device boots up in the BroadcastReceiver or in the Service
