Answer 1

Use the below method to get full class name (package+class name) of the current activity and check if it is equal to full class name (package+class name) of activity you want:

 public String getCurrentClass() {

    ActivityManager manager = (ActivityManager) getSystemService(ACTIVITY_SERVICE);
    List runningTaskInfo = manager.getRunningTasks(1);

    ComponentName componentInfo = runningTaskInfo.get(0).topActivity;
    String className = componentInfo.getClassName();
    return className;
 }
