Sample demonstrating OAuth authentication on Wear 2.0.
The sample demonstrates the flow between a Wear app and the Android Wear companion app for handling OAuth authentication.
The flow starts by tapping the Google+ authentication button on the app, and the OAuth consent web view on the Android Wear companion app. Once the user accepts and provides consent, flow is returned back to the watch. The watch makes a direct HTTP call to exchange the authorization code for OAuth tokens, and then makes a follow-up authenticated call to the Google OAuth 2.0 API.
Please have Android Studio installed and configuredi

This sample uses the Gradle build system. To build this project, use the "gradlew build" command or use "Import Project" in Android Studio.
Patches are encouraged, and may be submitted by forking this project and submitting a pull request through GitHub. Please see CONTRIBUTING.md for more details.
Setup steps:
1) Download and install Android Studio if you haven't already.
2) Note that Android Studio should already have the Wear-related support libraries and Play Services packages available in the SDK manager and should be able to resolve them by doing the following:
a) Right-click on the app module and select Open Module Settings... b) Click on the Dependencies tab c) Resolve the libraries referenced as compile targets in the app/build.gradle file and add them as dependencies to the module
In case you're unable to find the relevant Wear support libraries from the Android Studio SDK manager, you can also download and setup the libraries from the Wear 2.0 Developer Preview 4 developer docs:
https://developer.android.com/wear/preview/start.html
3) Download and install the latest Android Wear companion app also available at the preview link above.
4) In the Google API console, select an existing or create a new project and register it as an OAuth 2.0 client following the first set of instructions at the link below:
https://developers.google.com/identity/sign-in/web/server-side-flow
Note there is no need to progress beyond setting up the project as an OAuth client and obtaining the client_id and client_secret keys.
Also, make sure to register https://android.com/wear/3p_auth/
4) Update the WearOAuthActivity.java file to include the client_id and client_secret from the Google API project you previously selected to configure your OAuth client.
In this sample, the Wear app makes the direct HTTP call to exchange the authorization code for auth tokens, and thus the client_id and client_secret are both exposed in the Wear APK.
This IS NOT the standard practice, and you would normally want to
set the redirect URI to your own server URL, where the server can
perform the authorization code token exchange and then redirect the
user to the special https://android.com/wear/3p_auth/
For the purposes of this sample, the watch is handling the token exchange.

Demonstrates the OAuth flow on Android Wear. This sample currently handles the callback from the Android Wear companion app after receiving user consent, and the follow-up call to perform the OAuth token exchange before making authenticated API calls. * The sample uses the Google+ and Google OAuth 2.0 APIs, but can be easily extended for any other OAuth 2.0 provider.
This method should be called with any OAuth 2.0 URL scheme and for any provider. The callback object is called after the user provides consent on the authorization screen on the Android Wear companion app.
Helper method to update display with fetched results on the activity view. * @param text Returned text to display
Handles the callback from the Android Wear phone app after user consents to the OAuth authorization screen. Currently this callback performs both the token exchange for the authorization code, and a follow test authenticated call to the Google OAuth 2.0 API.
