java.lang.NoSuchMethodError: No static method dispatch Unhandled KeyEvent Pre

Question

When migrating to androidx I am getting above error when back pressing.

   java.lang.NoSuchMethodError: No static method dispatchUnhandledKeyEventPre(Landroid/view/View;Landroid/view/KeyEvent;)Z in class Landroidx/core/view/ViewCompat; or its super classes (declaration of 'androidx.core.view.ViewCompat' appears in 1/split_lib_dependencies_apk.apk)

I think in ViewCompat class does not have dispatchUnhandledKeyEventPre method. I am using some third party dependency so I don't know which method causing it

Answer 1

check you are using 1.0.0-beta01 version of appcompat library

Answer 2

For me, going to the gradle.build file and making sure that all the dependencies are up-to-date (new versions) fixed this problem.
