3. Now create a new Class and Named it As source url MyService.java extend that class with Service and Implement some abstract Methods or Add Below Code into That

 package com.targetandroid.info.myservice;  
   
 import android.app.Service;  
 import android.content.Intent;  
 import android.os.IBinder;  
 import android.os.Vibrator;  
 import android.support.annotation.Nullable;  
 import android.widget.Toast;  
   
 /**  
  * Created by Faizan on 16-11-17.  
  */  
   
 public class MyService extends Service {  
   
   //create time variable to count how much time the service in running  
   int time=0;  
     
   //this will start and stop our service  
   boolean stop=false;  
   
   public MyService() {  
   }  
   
   @Nullable  
   @Override  
   public IBinder onBind(Intent intent) {  
     return null;  
   }  
   
   
   //this method Will Start Our Service  
   @Override  
   public int onStartCommand(Intent intent, int flags, int startId) {  
   
     Toast.makeText(this, "Service Started at " + String.valueOf(time), Toast.LENGTH_SHORT).show();  
   
   
     Thread t=new Thread(){  
   
       @Override  
       public void run() {  
         while (!stop) {  
             
           try {  
             //to run the thread every second  
             sleep(1000);  
   
   
           } catch (InterruptedException e) {  
   
             e.printStackTrace();  
   
           }  
           //increase value of time by one  
           time++;  
             
           //phone will vibrate after every 5 second  
           if (time % 5 == 0) {  
   
             Vibrator v = (Vibrator) getApplicationContext().getSystemService(VIBRATOR_SERVICE);  
             v.vibrate(500);  
   
           }  
   
         }  
       }  
     };  
     t.start();  
     return START_NOT_STICKY;  
   }  
   
   //this method we call when we stop our Service  
   @Override  
   public void onDestroy() {  
     super.onDestroy();  
     stop=true;  
     Toast.makeText(this, "Service Destroyed after " + String.valueOf(time)+" Second", Toast.LENGTH_SHORT).show();  
   }  
 }  

4. Now Open Our go to site MainActivity.class and Add Below Code

package com.targetandroid.info.myservice;  
   
 import android.content.Intent;  
 import android.support.v7.app.AppCompatActivity;  
 import android.os.Bundle;  
 import android.view.View;  
 import android.widget.Button;  
   
 public class MainActivity extends AppCompatActivity {  
     
   private Button bt_startservice,bt_stopservice;  
     
   @Override  
   protected void onCreate(Bundle savedInstanceState) {  
     super.onCreate(savedInstanceState);  
     setContentView(R.layout.activity_main);  
   
     bt_startservice=(Button)findViewById(R.id.bt_startservice);  
     bt_stopservice=(Button)findViewById(R.id.bt_stopservice);  
           
       
       
     bt_startservice.setOnClickListener(new View.OnClickListener() {  
   
       @Override  
       public void onClick(View v) {  
         startservice();  
       }  
     });  
   
     bt_stopservice.setOnClickListener(new View.OnClickListener() {  
       @Override  
       public void onClick(View v) {  
         stopservice();  
   
       }  
     });  
   
   
   }  
   
   //Start Our Service  
   private void stopservice() {  
   
     stopService(new Intent(getBaseContext(), MyService.class));  
   
   }  
   
   //Kill or Destroy our Service  
   private void startservice() {  
   
     startService(new Intent(getBaseContext(),MyService.class));  
   }  
 }  

5. Before running Your Project add this two Set of Code into  source url AndroidManifest.xml

  • Add a Permission Above Application Tag for Vibration
 <uses-permission android:name="android.permission.VIBRATE" /> 
<service  
       android:name=".MyService"  
       android:enabled="true">  
     </service>  

 

This is My AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>  
 <manifest xmlns:android="http://schemas.android.com/apk/res/android"  
   package="com.targetandroid.info.myservice">  
   
   <uses-permission android:name="android.permission.VIBRATE" />  
   
   <application  
     android:allowBackup="true"  
     android:icon="@mipmap/ic_launcher"  
     android:label="@string/app_name"  
     android:roundIcon="@mipmap/ic_launcher_round"  
     android:supportsRtl="true"  
     android:theme="@style/AppTheme">  
     <activity android:name=".MainActivity">  
       <intent-filter>  
         <action android:name="android.intent.action.MAIN" />  
   
         <category android:name="android.intent.category.LAUNCHER" />  
       </intent-filter>  
     </activity>  
   
     <service  
       android:name=".MyService"  
       android:enabled="true">
