Unable to find method 'org.gradle.api.tasks.testing.Test.getTestClassesDirs()Lorg/gradle/api/file/FileCollection;'.
Possible causes for this unexpected error include:

• Gradle's dependency cache may be corrupt (this sometimes occurs after a network connection timeout.)
  Re-download dependencies and sync project (requires network)
• The state of a Gradle build process (daemon) may be corrupt. Stopping all Gradle daemons may solve this problem.
  Stop Gradle build processes (requires restart)
• Your project may be using a third-party plugin which is not compatible with the other plugins in the project or the version of Gradle requested by the project.

did both the bolded part but unfortunately, to no avail.

with the option to OTP only login will be more good!

Hi!

I'd like to center the views in the screen. Is it possible to modify gravity?

java.lang.NullPointerException: Attempt to invoke virtual method 'void android.support.v7.app.ActionBar.hide()' on a null object reference

Nice Library... It would be awesome if there's a way to add custom edittexts for login and sign up screens and retrieve there values when needed. Thanks

I imported gradle into my project, but when I try to execute app it crashes.
Logcat gives me that error "void android.support.v7.app.ActionBar.hide()' on a null object reference"
on super.onCreate(savedInstanceState);
Manifest and theme are the same of the example.

Any Suggestions ?
Thank you
