How to check if a service is running on Android?


How do I check if a background service is running?

I want an Android activity that toggles the state of the service -- it lets me turn it on if it is off and off if it is on.

I had the same problem not long ago. Since my service was local, I ended up simply using a static field in the service class to toggle state, as described by hackbod here

EDIT (for the record):

Here is the solution proposed by hackbod:

If your client and server code is part of the same .apk and you are binding to the service with a concrete Intent (one that specifies the exact service class), then you can simply have your service set a global variable when it is running that your client can check.

We deliberately don't have an API to check whether a service is running because, nearly without fail, when you want to do something like that you end up with race conditions in your code.

I use the following from inside an activity:

private boolean isMyServiceRunning(Class<?> serviceClass) {
    ActivityManager manager = (ActivityManager) getSystemService(Context.ACTIVITY_SERVICE);
    for (RunningServiceInfo service : manager.getRunningServices(Integer.MAX_VALUE)) {
        if (serviceClass.getName().equals(service.service.getClassName())) {
            return true;
    return false;

And I call it using:


This works reliably, because it is based on the information about running services provided by the Android operating system through ActivityManager#getRunningServices.

All the approaches using onDestroy or onSometing events or Binders or static variables will not work reliably because as a developer you never know, when Android decides to kill your process or which of the mentioned callbacks are called or not. Please note the "killable" column in the lifecycle events table in the Android documentation.
