Android: check if wear app is installed on paired watch

Question

I have two android apps(mobile/watch), and I want to check on the mobile app if the wear app is installed on the watch or not.

Any thoughts?

I searched but no results.

It's described in Detect your app on another device, there is also a sample in Github.

In a nutshell, you should:

1. Add res/values/wear.xml file to your watch module, specifying your app's capability:

<resources xmlns:tools="http://schemas.android.com/tools"
        tools:keep="@array/android_wear_capabilities">
    <string-array name="android_wear_capabilities">
        <item>your_custom_app_capability</item>
    </string-array>
</resources>

2. On the phone app, add a listener to CapabilityClient:

        val capabilityClient = Wearable.getCapabilityClient(this)

        capabilityClient.addListener({ capabilityInfo -> {
            // the watch with the wear app that contains
            // your custom capability can be retrieved from:
            capabilityInfo.nodes
        } }, "your_custom_app_capability")
