How to package a WatchFace only App for Google Play publishing

Question

So far

I am developing a watch face app for android wear.

I have created 2 modules:

1. Wear - The Watch face that works fine on development
2. Mobile - An empty module with no activity as suggested by the comments

I have added the wear module to the mobile as a dependancy as described in packaging wear apps for the playstore

The app is in alpha in the playstore. I have uploaded the mobile-release.apk.

The app installs fine on my mobile but the wear module, the WatchFace will not install on my wear device. This is my problem.

What am I doing wrong?

Here are my manifests and Gradle configs

Mobile Manifest

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.dimitrioskanellopoulos.athletica">

<uses-permission android:name="android.permission.BODY_SENSORS"/>
<uses-permission android:name="android.permission.VIBRATE"/>
<uses-permission android:name="android.permission.WAKE_LOCK" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>

<application android:allowBackup="true" android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name" android:supportsRtl="true"
    android:theme="@style/AppTheme">

</application>

Wear Manifest

<service
  android:name="com.dimitrioskanellopoulos.athletica.WatchFaceService"
  android:label="@string/app_name"
  android:permission="android.permission.BIND_WALLPAPER">

  <meta-data
    android:name="android.service.wallpaper"
    android:resource="@xml/watch_face" />

  <meta-data
      android:name="com.google.android.wearable.watchface.preview"
      android:resource="@drawable/preview_rectangular" />

  <meta-data
      android:name="com.google.android.wearable.watchface.preview_circular"
      android:resource="@drawable/preview_circular" />

  <intent-filter>
    <action android:name="android.service.wallpaper.WallpaperService" />
    <category android:name="com.google.android.wearable.watchface.category.WATCH_FACE" />

Any help would be much appreciated!

Answer 1

Well after some time it installed. Took several uninstalls/installs.

The updated manifests are result of the comments and thanks for that.
