NoClassDefFoundError: WearableActivityController$AmbientCallback;

Hello,

I am completely new to Android development and wanted to use ActiveAndroid in my app. I tried to install it following the documentation, like this:

`<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.example.inventorymanagement">

<uses-permission android:name="android.permission.WAKE_LOCK" />
<uses-permission android:name="android.permission.INTERNET"/>
<uses-feature android:name="android.hardware.type.watch" />

<application

    ...

    android:name="com.activeandroid.app.Application"
    >

    <meta-data android:name="AA_DB_NAME" android:value="cardelli_db" />
    <meta-data android:name="AA_DB_VERSION" android:value="5" />

    ...

    <activity
        android:name=".MainActivity"
        android:label="@string/app_name"
        android:theme="@style/Theme.InventoryManagement.NoActionBar">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

I also dragged the .jar to my libs folder and imported the library. Android Studio finds the annotations when I try to use them.

However, when I start the app, I get a "NoClassDefFoundError". Please see below

It looked like a dependency is missing. "AndroidActivityController" is appearently part of AndroidWear. I tried adding the dependency stated there by adding "implementation "androidx.wear:wear:1.2.0-alpha03"" to my build.gradle, but no help.

I searched on the web for this but could not find anything. Any help is much appreciated!

Best regards.
