How to get pid of Activity configured to run in distinct process?

I have an Activity that needs to run in a separate process (which I have named :ChildWebView) to workaround an issue with WebViewDatabase. As part of the workaround, after the Activity is finished, I need to kill its process. Right now, I just call android.os.Process.myPid() in that activity and pass the result back to the parent main process inside an Intent. Is there a way for the parent main process to look up the pid of one of its child accessory processes by name?

This didn't require any special permissions. It's pretty straightforward.

public void killProcessNamed(Context context, String processName) {
        ActivityManager activityManager = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
        List<ActivityManager.RunningAppProcessInfo> runningAppProcessInfoList = activityManager.getRunningAppProcesses();
        if (runningAppProcessInfoList != null) {
            for (ActivityManager.RunningAppProcessInfo runningAppProcessInfo : runningAppProcessInfoList) {
                if (runningAppProcessInfo.processName.equals(processName)) {
                    android.os.Process.killProcess(runningAppProcessInfo.pid);
                    break;
                }
            }
        }
    }
