Basic Android background Service

Running sample program for background service

Step 1 :
Create sample service class

package com.javaorigin.android.sample.service;

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 {
 
   String tag="TestService";
   @Override
   public void onCreate() {
       super.onCreate();
       Toast.makeText(this, "Service created...", Toast.LENGTH_LONG).show();      
       Log.i(tag, "Service created...");
   }
 
   @Override
   public void onStart(Intent intent, int startId) {      
       super.onStart(intent, startId);  
       Log.i(tag, "Service started...");
   }
   @Override
   public void onDestroy() {
       super.onDestroy();
       Toast.makeText(this, "Service destroyed...", Toast.LENGTH_LONG).show();
   }

   @Override
   public IBinder onBind(Intent intent) {
       return null;
   }
}

Step 2 :
Create sample Activity class

package com.javaorigin.android.sample.service;

import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.util.Log;
import android.widget.TextView;
import android.widget.Toast;

public class SampleAction extends Activity {
   @Override
   protected void onCreate(Bundle savedInstanceState) {      
       super.onCreate(savedInstanceState);
       TextView view = new TextView(this);      
       view.setText("Service Test");
       Intent i = new Intent();
       i.setClassName( "com.javaorigin.android.sample.service",
        "com.javaorigin.android.sample.service.MyService" );
       bindService( i, null, Context.BIND_AUTO_CREATE);
       this.startService(i);      
       setContentView(view);
   }
}

Step 3:
Configure AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
   package="com.javaorigin.android.sample.service" android:versionCode="1"
   android:versionName="1.0">
   <application icon="@drawable/icon" label="@string/app_name">
       <service class=".MyService" name=".MyService">
         <intent-filter>
           <action android:value="com.javaorigin.android.sample.service.MY_SERVICE"
                   android:name=".MyService" />

           </intent-filter>
       </service>
      <activity android:name=".SampleAction"
                 android:label="@string/app_name">
           <intent-filter>
               <action name="android.intent.action.MAIN">
               <category name="android.intent.category.LAUNCHER">
           </intent-filter>
       </activity>

   </application>
   <uses-sdk minsdkversion="8">

</manifest>
