Android Wear Google Sign-In Sample


Sample demonstrating Google Sign-In implementation on Wear 2.0, as well as a Google Sign-In button matching Wear material design.

The button included in this sample should be used as throwaway code for all Wear integrations until the final version lands in Play Services, and maintained there going forward.


Please have Android Studio installed and configured. If you're not using Android Studio, you can still follow these instructions but will need to adjust them according to your environment.


You can find support by posting up on the Android Wear Developers Community page at the link below:

Getting Started

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 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:

3) Follow the setup instructions for integrating Google Sign-in into an Android app at the link below. Remember to use the package name when configuring your project and credentials, or otherwise modify the sample appropriately if you want to use a different package name.

4) Update the strings.xml file for the string value 'server_client_id' to the value for the OAuth web client id created in step 3).

Special Notes

1) For Wear integrations using Google Sign-In, please use the Wear-styled Google Sign-In button contained in this sample as throwaway code. The final version of this button will be released in a future Play Service version, following the Wear 2.0 final release
