android - Wrong output of ActivityManager.getRunningAppProcesses?

Question

I'm trying to check if the specific process is running by using getRunningAppProcesses inside of BroadcastReceiver.onReceive(Context context, Intent intent). But when that specific application is completely closed method getRunningAppProcesses tells me that it's running and have foreground importance (proc.importance == 100). How is it can be? Is it i'm getting an old context?
