How to determine if an Android Service is running in the foreground?

Question

I have a service which I believe to have running in the foreground, How do I check if my implementation is working?

Answer 1

private boolean isServiceRunning(String serviceName){
    boolean serviceRunning = false;
    ActivityManager am = (ActivityManager) this.getSystemService(ACTIVITY_SERVICE);
    List<ActivityManager.RunningServiceInfo> l = am.getRunningServices(50);
    Iterator<ActivityManager.RunningServiceInfo> i = l.iterator();
    while (i.hasNext()) {
        ActivityManager.RunningServiceInfo runningServiceInfo = i
                .next();

        if(runningServiceInfo.service.getClassName().equals(serviceName)){
            serviceRunning = true;

            if(runningServiceInfo.foreground)
            {
                //service run in foreground
            }
        }
    }
    return serviceRunning;
}

If you want to know if your service is running in foreground just open some others fat applications and then check if service is still running or just check flag service.foreground.

public static boolean isServiceRunningInForeground(Context context, Class<?> serviceClass) {
      ActivityManager manager = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
      for (ActivityManager.RunningServiceInfo service : manager.getRunningServices(Integer.MAX_VALUE)) {
         if (serviceClass.getName().equals(service.service.getClassName())) {
            if (service.foreground) {
               return true;
            }

         }
      }
      return false;
   }

A more efficient variation of answer: https://stackoverflow.com/a/36127260/1275265

public static boolean isServiceRunningInForeground(Context context, Class<?> serviceClass) {
   ActivityManager manager = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
   for (ActivityManager.RunningServiceInfo service : manager.getRunningServices(Integer.MAX_VALUE)) {
      if (serviceClass.getName().equals(service.service.getClassName())) {
         return service.foreground;
      }
   }
   return false;
}

This worked for me in the Coinverse app for crypto news.

It's is the most concise Kotlin solution. Thanks to Abbas Naqdi in this GitHub issue.

@Suppress("DEPRECATION") // Deprecated for third party Services.
fun <T> Context.isServiceRunning(service: Class<T>) =
        (getSystemService(ACTIVITY_SERVICE) as ActivityManager)
            .getRunningServices(Integer.MAX_VALUE)
            .any { it.service.className == service.name }
