Auto start a service with Intent of "android.intent.action.BOOT_COMPLETED" action

Last exercise "Start a service to send Notification" show how to start a service by user clicking in a activity. In this exercise, a BroadcastReceiver will be implemented to receive Intent of "android.intent.action.BOOT_COMPLETED" action after power-up, no interactive with user.

"android.intent.action.BOOT_COMPLETED" is Broadcast Action, is broadcast once, after the system has finished booting. It can be used to perform application-specific initialization. You must hold the RECEIVE_BOOT_COMPLETED permission in order to receive this broadcast.

Create a new class AutoStartNotifyReceiver.java, extends BroadcastReceiver. Simple do the same thing as that in Start button OnClickListener in last exercise "Start a service to send Notification", start a service.

package com.exercise.AndroidNotifyService;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;

public class AutoStartNotifyReceiver extends BroadcastReceiver {
 
 private final String BOOT_COMPLETED_ACTION = "android.intent.action.BOOT_COMPLETED";

 @Override
 public void onReceive(Context context, Intent intent) {
  // TODO Auto-generated method stub
  
  if(intent.getAction().equals(BOOT_COMPLETED_ACTION)){
   Intent myIntent = new Intent(context, com.exercise.AndroidNotifyService.NotifyService.class);
   context.startService(myIntent);
  }

 }

}

In order to receive Intent of "android.intent.action.BOOT_COMPLETED", modify AndroidManifest.xml to add <receiver> for AutoStartNotifyReceiver, also grant permission of "android.permission.RECEIVE_BOOT_COMPLETED".

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.exercise.AndroidNotifyService"
    android:versionCode="1"
    android:versionName="1.0">
  <uses-sdk android:minSdkVersion="7" />
  <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"></uses-permission>

  <application android:icon="@drawable/icon" android:label="@string/app_name">
      <activity android:name=".AndroidNotifyService"
                android:label="@string/app_name">
          <intent-filter>
              <action android:name="android.intent.action.MAIN" />
              <category android:name="android.intent.category.LAUNCHER" />
          </intent-filter>
      </activity>
  <service android:name=".NotifyService"/>
  <receiver android:name=".AutoStartNotifyReceiver" android:label="@string/app_name">
   <intent-filter>
    <action android:name="android.intent.action.BOOT_COMPLETED" />
    <category android:name="android.intent.category.LAUNCHER" />
   </intent-filter>
  </receiver>
  </application>
</manifest>
