Android Java.Lang.Verifyerror

Android java.lang.VerifyError?

Android uses a different class file format. Are you running the 3rd party JAR files through the "dx" tool that ships with the Android SDK?

WorkManager: java.lang.VerifyError: Verifier rejected class androidx.work.impl.OperationImpl

The solution was a tad weird, I admit.

My first step was to update the dependency versions for WorkManager as well as Coroutines to the latest versions (as stated in the question details). After that, I updated the provider<> tag in my AndroidManifest.xml file from this:

<provider
    android:name="androidx.work.impl.WorkManagerInitializer"
    android:authorities="${applicationId}.workmanager-init"
    tools:node="remove" />

to this:

<provider
    android:name="androidx.startup.InitializationProvider"
    android:authorities="${applicationId}.androidx-startup"
    android:exported="false"
    tools:node="merge" />

After that, everything just worked fine. /p>
