How to start a service from an activity in android?

Question

am too much confused in starting a background service from an activity and am providing the code which i used to start the service from an activity.

private boolean isMyServiceRunning() {
    ActivityManager manager = (ActivityManager) getSystemService(ACTIVITY_SERVICE);
    Log.v("Running activities", manager.toString());
    for (RunningServiceInfo service : manager.getRunningServices(Integer.MAX_VALUE)) {
 if ("com.*.*.service.Service".equals(service.service.getClassName())) {
     return true;
       }
    }
     Log.v("Currently running services in andorid phone", "other services");
    return false;
}

Above code is to check whether the service is running or not.If it is not means am doing this

if(isMyServiceRunning()) {
                          System.out.println("Service is running");
                        } else {
                          System.out.println("Service is not running");
                          Intent serviceIntent = new Intent();
                          serviceIntent.setAction("com.*.*.service.Service");
                          startService(serviceIntent);
                        }

Suggest your answers and solutions to solve this problem.

What is the problem in your code ? Are you getting any exception or error ? — Amit, Sep 08 '14 at 05:00

Intent intent = new Intent(yourActivity.this,yourservice.class); yourActivity.this.startService(intent); — Mr X, Sep 08 '14 at 05:02
If you can start your service then use Intent intent = new Intent(this, YOUR_SERIVICE_NAME.class); startService(intent); and also define in manifest. — Divyang Metaliya, Sep 08 '14 at 05:02
No exception occurring always the code moves to the `else` part. — Sabari Karthik, Sep 08 '14 at 05:04
Then how can I identify whether the service is started or not @PRAKASHUBHADIYA — Sabari Karthik, Sep 08 '14 at 05:06

If you can start your service then use

public class YourService extends Service {

public static boolean isRunning = false;

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

     @Override
     public int onStartCommand(Intent intent, int flags, int startId) {
         isRunning = true;
         return START_STICKY;
     }
}

if(!YourService.isRunning){
    Intent intent = new Intent(this, YourService.class);
    startService(intent);

    Date date = new Date(System.currentTimeMillis());
    SimpleDateFormat sdf = new SimpleDateFormat("hh:mm aa");
    DateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd");
    Date dt = new Date(System.currentTimeMillis());
    String strTime = sdf.format(dt);
    String strDate = dateFormat.format(date);
}

and also define

<service android:name="com.mypackagename.YourService"></service>

in manifest.

If you want check service running or not then use one static variable in service and check before start your service. If that false then start service.

I have added the `` in manifest file. – Sabari Karthik Sep 08 '14 at 05:08
This is possible or not? `Intent service = new Intent(); service.setAction("com.*.*.Service"); startService(service);` – Sabari Karthik Sep 08 '14 at 05:09
@SabariKarthik you give full package name in manifest file ?? if not then give full package name. – Divyang Metaliya Sep 08 '14 at 05:10

And also suggest how to start a receiver after starting a service or before starting service. – Sabari Karthik Sep 08 '14 at 13:15
@SabariKarthik go to http://developer.android.com/reference/android/content/BroadcastReceiver.html and implement receiver in your activity. – Divyang Metaliya Sep 08 '14 at 13:31
I saw that link,that is full of theories @DivyangMetalia I need some examples because am new in Android development. – Sabari Karthik Sep 08 '14 at 13:36
