I would like to compare the calling activity to others to know which one called the current activity. I tried:

getCallingActivity().getClassName().toString().equals(MainActivity.class.toString())

It doesn't work, except by passing a value in the calling Intent, how can we compare classes using getCallingActivity() or getCallingPackage()?

You can compare the calling activity in the following manner if the activity is started for result from another activity.

 if (getCallingActivity().getClassName().equals(MainActivity.class.getName())) { /* here the main activity is calling activity*/ }else{ /*other activity is calling activity*/ }

hey i try this logic but it give me exaption like this: Attempt to invoke virtual method 'java.lang.String android.content.ComponentName.getClassName()' on a null object reference
did u started activity for result?? if not then getCallingActivity() will return null which will cause null pointer
if (getCallingActivity().getClassName().equals(PlayerActivity.class.getCanonicalName())) code = 100; else { code = isPlaylist.equals("True") ? 100 : 200; } setResult(code, in);
use getName() instead of getCanonicalName() see the differences here stackoverflow.com/questions/15202997/…
then the activity is not started for result. start it with startActivityForResult then everything will be fine
