The question says it all. Unfortunately it's not as simple as creating a new project, connecting a device and pushing the run button. Here are the details:
I'm trying to create a new Wear OS only app (i.e. no phone or tablet support). API Level is set to 28 (Android 8), with a Blank Wear Activity. After finishing the new project wizzard, Android Studio prints the following welcome message in shiny red letters:
Manifest merger failed : Attribute application@appComponentFactory value=(android.support.v4.app.CoreComponentFactory) from [com.android.support:support-compat:28.0.0] AndroidManifest.xml:22:18-91
is also present at [androidx.core:core:1.0.0] AndroidManifest.xml:22:18-86 value=(androidx.core.app.CoreComponentFactory).
Suggestion: add 'tools:replace="android:appComponentFactory"' to <application> element at AndroidManifest.xml:9:5-35:19 to override.
Following the recommendation and adding tools:replace="android:appComponentFactory" to <application> element at AndroidManifest.xml changed the error message to:

That did not make it any better... Reverting the manifest modification and googling the root cause (Manifest merger failed) seemed to be the better approach, which lead to this answer here at SO that suggests to add the following two lines at gradle.properties:
android.useAndroidX=true
android.enableJetifier=true
And finally it builds! However, the app instantly crashes when trying to run it on the watch:

So this isn't the right fix neither...
Do you have any ideas what could be wrong here? Creating a new project and running it on a device should work out of the box, but it seems there's something seriously broken.
Btw. Android Studio Version 3.2.1, with SDK Platform Tools 29.0.2 and SDK Tools 26.1.1 is used. SDKs 21 til 29 are installed.
Any advise how to get an empty wear project running is appreciated, Thank you.
