How to restart the service when application closed?

Question

I am using the service for sending notifications every 30 sec. When my application is in background mode it is working fine. Every notification receives properly. But when I kill/close my application the service stops and I am not receiving any notification.

Anybody have an idea on how to run the service when application is closed or killed?

here is my manifest file`
``

<uses-sdk
    android:minSdkVersion="11"
    android:targetSdkVersion="21" />

<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" />
<uses-permission android:name="android.permission.GET_TASKS" />
<uses-permission android:name="android.permission.KILL_BACKGROUND_PROCESSES" />

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name" >
    <activity
        android:name=".MainActivity"
        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=".MainService"
        android:enabled="true"
        android:exported="false"
         >
    </service>
    <service android:name=".NewService" >
    </service>

    <activity
        android:name=".MainActivity2"
        android:label="@string/title_activity_main_activity2" >
    </activity>
</application>

If you want to continue your service even after killing application from Recent app's list, set stopWithTask as false in manifest:

<service
    android:enabled="true"
    android:name=".MyService"
    android:exported="false"
    android:stopWithTask="false" />

And your Service should be sticky.

@Override
public final int onStartCommand(Intent intent, int flags, int startId) {
    Log.i(TAG, "onStarCommand(): Received id " + startId + ": " + intent);
    return START_STICKY; // run until explicitly stopped.
}

Refer this question for all details.

And if you want to perform some additional action when application gets removed from recent list, you can override method onTaskRemoved

Hope this helps.
