How to check if a service is already running or not in android?

Question

In my project I am starting a service when a button is clicked. But I don't want to start that service again when that button is clicked unless the previous one is already stopped. So I need to check first whether the service is running or not. I used the following method

private boolean isMyServiceRunning() {
    ActivityManager manager = (ActivityManager) getSystemService(ACTIVITY_SERVICE);
    for (RunningServiceInfo service : manager.getRunningServices(Integer.MAX_VALUE)) {
        if ("com.example.MyService".equals(service.service.getClassName())) {
            return true;
        }
    }
    return false;
}

But its not working for me, it doesnt give any exception but always returns false. what should I do now?

I took that method from your link before, but its not working — Reyjohn, May 30 '12 at 13:42
If you debug through the code, is your service being picked up in the `for` loop? ie Is your service actually being found by `manager.getRunningServices()`? — wattostudios, May 30 '12 at 13:43
This didn't work for my Intent Service, the below solution worked https://stackoverflow.com/questions/7060793/how-to-check-if-an-intentservice-was-started — Code_Yoga, Jun 21 '17 at 07:18

I think the reason why your service is not listed in running services is the way you start your service. The following proposal is the same thread you took your method from.

You MUST call startService for your service to be properly registered and
passing BIND_AUTO_CREATE will not suffice.

Like the following:

Intent bindIntent = new Intent(this,ServiceTask.class);
startService(bindIntent);
bindService(bindIntent,mConnection,0);

Try this and see if it works for you too.

Your method return false because after stop, process is destroyed by system if there are no any clients bound to service.
