please help in getting rid of this error...

 

[Deleted User]

Please show all the code for class RegisterActivity.java. Need to see the declaration of variable loadingBar.
The error indicates that either a) There's no method setTitle() defined or b) you're using the wrong method parameters for this method, on the class relevant to variable loadingBar.

Your object loadingBar is ProgressBar. Android ProgressBar does not have methods setTitle() and dismiss();
To "setTitle", If you want to show some title above loadingBar, just add TextView in layout and use setText() method.
To "dismiss", if you want to hide loadingBar, use setVisibility(Visibility.INVISIBLE) method.
