Google play APKs supporting Android Wear must have

I have tried to upload new Android wear app to google play developer console and I've got the following message:

Upload failed APKs that use the 'android.hardware.type.watch' feature must have minimum SDK version of at least 23, and this APK has 20. If you are embedding a watch APK inside a phone APK, the phone APK does not need to use the 'android.hardware.type.watch' feature.

my app is configured to sdk 20. I need it to be available for android 5.1. my app is designed for wear only and not for both wear and phone/tablets.

things I have tried and didn't help:

1.remove

android:name="android.hardware.type.watch"

-the app is abled to be uploaded but I couldn't run it on a virtual watch device, it says:

missing uses-feature watch, non-watch apks cannot be launched on a watch

2.instead of removing

android:name="android.hardware.type.watch"

I have tried changing it to:

<uses-feature
    android:name="android.hardware.type.watch"
    android:required="false" />

-the app is abled to be uploaded but I couldn't run it on a virtual watch device, it says:

missing uses-feature watch, non-watch apks cannot be launched on a watch

tried changing the minimum sdk from 20 to 23 -the app won't work on 20-22 sdk devices.

My manifest file:

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

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

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@android:style/Theme.DeviceDefault">
        <activity
            android:name=".MainActivity"
            android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

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

</manifest>

回答1:

There are no Android Wear devices with an API-Level below 23. You are not restricting the customer base when uploading the App with a minimum SDK Version of 23.

回答2:

Android Wear 2.0 Developer Preview 4 has extensive documentation for your question, see the App Distribution topic.

To paraphrase:

Android Wear 2.0 apps need a minimum API level of 24
If you want to use the old distribution model (of using an embedded APK), you may use API level 23

It seems like you want to distribute a standalone Android Wear 2.0 app, so you should set the API level to 24.

Also, you must set up targeting for watches by providing <uses-feature android:name="android.hardware.type.watch" /> and mark the app as standalone (see this part of the docs) by specifying <meta-data android:name="com.google.android.wearable.standalone" android:value="true" />
