How to implementing START_STICKY for a service?

Before getting into an example, we should know what service is in android. Service is going to do back ground operation without interacting with UI and it works even after activity destroy.

START_STICKY -  If service is started with START_STICKY return type, it going to work in back ground even if activity is not foreground if android forcefully closed service due to memory problem or some other cases, it will restart service without interaction of the user.

This example demonstrates How to implementing START_STICKY for a service.

Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.

Step 2 − Add the following code to res/layout/activity_main.xml.

<?xml version = "1.0" encoding = "utf-8"?>
< xmlns:android = ""
   xmlns:app = ""
   xmlns:tools = ""
   android:layout_width = "match_parent"
   android:layout_height = "match_parent"
   tools:context = ".MainActivity">
      android:id = "@+id/text"
      android:layout_width = "wrap_content"
      android:layout_height = "wrap_content"
      android:text = "Start Service"
      android:textSize = "25sp"
      app:layout_constraintBottom_toBottomOf = "parent"
      app:layout_constraintLeft_toLeftOf = "parent"
      app:layout_constraintRight_toRightOf = "parent"
      app:layout_constraintTop_toTopOf = "parent" />

In the above code, we have taken text view, when user click on text view, it will start service and stop service.

Step 3 − Add the following code to src/

package com.example.andy.myapplication;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.TextView;
public class MainActivity extends AppCompatActivity {
   protected void onCreate(Bundle savedInstanceState) {
      final TextView text = findViewById(;
      text.setOnClickListener(new View.OnClickListener() {
         public void onClick(View v) {
            if (isMyServiceRunning(service.class)) {
               stopService(new Intent(MainActivity.this, service.class));
            } else {
               startService(new Intent(MainActivity.this, service.class));
   private boolean isMyServiceRunning(Class<?> serviceClass) {
      ActivityManager manager = (ActivityManager) getSystemService(Context.ACTIVITY_SERVICE);
      for (ActivityManager.RunningServiceInfo service : manager.getRunningServices(Integer.MAX_VALUE)) {
         if (serviceClass.getName().equals(service.service.getClassName())) {
            return true;
      return false;

In the above code to start and stop service. We have used intent and passed context and service class. Now create a service class in package folder as service.class and add the following code –

package com.example.andy.myapplication;
import android.annotation.TargetApi;
import android.content.Context;
import android.content.Intent;
import android.os.Build;
import android.os.IBinder;
import android.util.Log;
import android.widget.Toast;
public class service extends Service {
   public IBinder onBind(Intent intent) {
      return null;
   public void onCreate() {
   @RequiresApi(api = Build.VERSION_CODES.JELLY_BEAN)
   public int onStartCommand(Intent intent, int flags, int startId) {
      Toast.makeText(this, "Notification Service started by user.", Toast.LENGTH_LONG).show();
      Log.d("","Services is working background");
      return START_STICKY;
   @RequiresApi(api = Build.VERSION_CODES.N)
   public void onDestroy() {
      Toast.makeText(this, "Notification Service destroyed by user.", Toast.LENGTH_LONG).show();

In the above code we have called START_STICKY, now check for service information as shown below –

Step 4 − Add the following code to manifest.xml

<?xml version = "1.0" encoding = "utf-8"?>
<manifest xmlns:android = ""
   package = "com.example.andy.myapplication">
      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">
            <action android:name = "android.intent.action.MAIN" />
            <category android:name = "android.intent.category.LAUNCHER" />
     <service android:name = ".service"/>

Let's try to run your application. I assume you have connected your actual Android Mobile device with your computer. To run the app from android studio, open one of your project's activity files and click Run  icon from the toolbar. Select your mobile device as an option and then check your mobile device which will display your default screen –

In the above result is an initial screen, Click on Text view, it will start Notification service as shown below –

In the above result, service is startd now click on text view, it will stop notification service as shown below -
