java.lang.NoSuchMethodError: No super method

Question

Trying to use CameraX in Android.I am using code link .But i am facing Error
java.lang.NoSuchMethodError: No super method getLifecycle()Landroidx/lifecycle/Lifecycle; in class Landroidx/core/app/ComponentActivity; or its super classes

Answer 1

The problem is in the appcompact dependency. If you check the source code of the version you are using 1.0.2, there is no super method in the ComponentActivity class and the FragmentActivity is trying to call that method.

To fix this you need to upgrade the version to 1.1.0-rc01. In this version FragmentActivity use a LifecycleRegistry to get the LifeCycle

implementation 'androidx.appcompat:appcompat:1.1.0-rc01'
