This is my UploadActivity. The app lets me select a file , but crashes as soon as I press upload button. the Toast message of OnFailedListener is displayed everytime. I am choosing the correctimage file with correct naming conventions , but still facing the same problem. I have reffered to the documentation as well as tutorials , and implemented almost the same methods. What am I doing wrong?
