I have been trying to migrate my app to use androidx but I seem to encounter a strange error. From my activity which extends AppCompatActivity when I call getLifeCycle()
it throws the following exception
Caused by: java.lang.NoSuchMethodError: No super method getLifecycle()Landroidx/lifecycle/Lifecycle; in class Landroidx/core/app/ComponentActivity; or its super classes
at androidx.fragment.app.FragmentActivity.getLifecycle(FragmentActivity.java:324)
I believe that AppCompatActivity should be implementing LifecycleOwner but its not. Am I doing something wrong? Here's my gradle dependencies
implementation files("libs/jsoup-1.8.3.jar")
implementation "com.github.philjay:MPAndroidChart:v3.0.2"
implementation 'androidx.gridlayout:gridlayout:1.0.0'
implementation 'androidx.appcompat:appcompat:1.0.2'
implementation 'com.google.android.material:material:1.1.0-alpha01'
implementation "androidx.constraintlayout:constraintlayout:2.0.0-alpha2"
implementation 'androidx.constraintlayout:constraintlayout-solver:2.0.0-alpha2'
implementation 'androidx.cardview:cardview:1.0.0'

You should change the androidx.appcompat:appcompat
version to 1.1.0-alpha04
Just tried it in verision 1.1.0-alpha01
of androidx.appcompat:appcompat
and it is now working.
The LifecycleOwner
interface is now implemented by ComponentActivity
which is extended by FragmentActivity
-> AppCompatActivity
. You should now be able to get the lifecycle
object from your activities.
