PLEASE HELP GUYS PLEASE

It took me three days to figure out what's the problem in my code. After knowing my mistake i am feeling very ashamed as well as happy that i figured, it out.
the mistake is in the adapter code,
in.putExtra(" videourl", post.getVideourl());
String ttr = in.getStringExtra("videourl");
the difference between above two code line is the, in first line there is space before the videourl and in the second line there is no space before videourl, and that's a problem. :-)

My Quiz App is crashing when I load Categories from Firebase Firestore but able to recieve users data to firestore from App

When I try to load categories in any activity the quizapp is getting crashed when i load. But when i send users data to firestore, its working.
All the data set in DbQuery.java matches the names entered with Firestore data. But There is something wrong in this that whenever I load this data in login Activity, signup activity or splash activity the app is getting crashed.
Here is my code:

Both screens are in different Classes.
But it simply crashes before LoginScreen can reach to Category Screen. Any clue why this is not working? I have been trying to figure out and i used different variations of codes but all led me to to nothing. I have also tried on a different project but that also led me to nowhere. Thanks in advance

There are several problems with your code. You should check for error returned by setLanguage. You cannot call speakOut until onInit has been called. One way you can insure this is to disable the talk button in the xml layout file and enable it in onInit.
