Here is my code: First to get a list of running Apps do the following

public void RunningApps() {
        final PackageManager pm = getPackageManager();
        //Get the Activity Manager Object
        ActivityManager aManager = 
        (ActivityManager) this.getSystemService(ACTIVITY_SERVICE);
        //Get the list of running Applications
        List<ActivityManager.RunningAppProcessInfo> rapInfoList = 
                          aManager.getRunningAppProcesses();
        //Iterate all running apps to get their details
        for (ActivityManager.RunningAppProcessInfo rapInfo : rapInfoList) {
            //error getting package name for this process so move on
            if (rapInfo.pkgList.length == 0)
                continue; 

            try {
                PackageInfo pkgInfo = pm.getPackageInfo(rapInfo.pkgList[0],
                PackageManager.GET_ACTIVITIES);

                if (isSystemPackage(pkgInfo)) {
                    //do something here
                } 
                else {
                    //do something here
                }

            } catch (PackageManager.NameNotFoundException e) {
                e.printStackTrace();
                Log.d(TAG, "NameNotFoundException :" + rapInfo.pkgList[0]);
            }
        }
    }

The actual function to check if the running application is system app, and used in the previous method is given below

 /**
     * Return whether the given PackgeInfo represents a system package or not.
     * User-installed packages (Market or otherwise) should not be denoted as
     * system packages.
     *
     * @param pkgInfo The Package info object
     * @return Boolean value indicating if the application is system app
     */
    private boolean isSystemPackage(PackageInfo pkgInfo) {
        return (pkgInfo.applicationInfo.flags & 
                ApplicationInfo.FLAG_SYSTEM) != 0;
    }

I hope it helps.

This is not returning running system process `val rapInfoList = aManager.runningAppProcesses` This returns only app processes. Do you know how to get running system process list? — Kushal, Apr 11 '20 at 07:51

As per this documentation, it seems you can use FLAG_SYSTEM_PROCESS to identify a process is System process or not. Here is SO discussion on this.

Thanks for the reply. But I think FLAG_SYSTEM_PROCESS is for the RunningService not for RunningProcess . I need to check for Currently RunningProcess. – Dinesh Sharma Jan 24 '12 at 05:21

public static boolean isAppRunning(Context context, String packageName) {
    ActivityManager am = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
    List<ActivityManager.RunningTaskInfo> list = am.getRunningTasks(100);
    if (list.size() <= 0) {
      return false;
    }
    for (ActivityManager.RunningTaskInfo info : list) {
      if (info.baseActivity.getPackageName().equals(packageName)) {
        return true;
      }
    }
    return false;
}
