you need to post the associated code. the stacktrace is not enough to go on. — Timothy Winters, Jun 30 '18 at 13:20
code is building successfully and running fine.But it fails after clicking the login button instead of opening the next page — Akash, Jun 30 '18 at 13:22
that may be, but we cannot read minds. We can't help you unless we can see the code so we can figure out what is causing your crash. — Timothy Winters, Jun 30 '18 at 13:24
ok, first, that is not of much use there. edit your main question and add the code there. Second, is that all of the code? — Timothy Winters, Jun 30 '18 at 13:26
`Could not find method onClick(View) ` . You have added onClick inside xml . and you have not created this method in your Activity. — ADM, Jun 30 '18 at 13:27

**never** set click listeners in XML, or you will end up with this error. — Vladyslav Matviienko, Jun 30 '18 at 13:59

As @ADM mentioned in a comment to your “answer” @Akash your onClick method does not have the correct onClick method signature hence the java.lang.IllegalStateException: Could not find method onClick(View) in a parent or ancestor Context exception.
