Cross platform support by Telegram Messenger

Today, we are releasing the fifth and final developer preview for Android Wear 2.0. In this release, we have added iOS support and included a number of bug fixes and enhancements. Apps compiled with this preview are now ready for final submission to the Google Play Store, so it’s time to publish your apps. As Android Wear 2.0 approaches its final release in early February, we would like to thank you for your continued feedback during the developer preview program. Your input has helped us uncover bugs as well as drive critical product decisions. Thank you!

iOS Support

Since 2015, you’ve been able to pair Android Wear watches with iPhones, and now you can distribute your apps to iPhone-paired watches as well. To do so, just set the standalone=true flag in your watch app manifest. This lets the Play Store know that your watch app doesn’t require an Android phone app, and therefore can appear in the Play Store on watches paired to iPhones. To pair your watch to an iPhone and test, just follow these steps.

The available network bandwidth for standalone apps can be lower than expected, as the platform balances battery savings vs network bandwidth. Make sure to check out these guidelines for accessing the network, including accessing Wi-Fi and cellular networks on watches paired with iPhones.

Also with this developer preview release, Android Wear apps running on watches paired with iOS devices will be able to perform phone hand-off flows such as OAuth and RemoteIntent for launching a web page on a paired iOS device.

Uploading Your App to the Google Play Store

The final developer preview includes an update to the Wearable Support Library. Apps compiled with API level 25 and this support library are considered ready for deployment in the Google Play Store. Please note that there are no updates to the preview watch image or emulator in this developer preview release.

Other Enhancement and Bug Fixes

  • Navigation Drawer: Flip a flag to toggle to the single-page, icon-only action drawer, which provides faster, more streamlined navigation to different views in your app.
  • NFC HCE support: NFC Host Card Emulation FEATURE_NFC_HOST_CARD_EMULATION is now supported.
  • ProGuard and Complication API: New ProGuard configuration means complication data container classes will no longer be obfuscated. This fixes a ClassNotFoundException when watch faces are trying to access data supplied by a complication data provider.

Countdown to Launch

Thank you for the fantastic level of feedback we have gotten from you as developers. Check out g.co/wearpreview for the latest builds and documentation, and be sure to publish your apps before the Android Wear 2.0 consumer launch in early February. As we work towards the consumer launch and beyond, please continue filing bugs or posting comments in our Android Wear Developers community. We can’t wait to see your Android Wear 2.0 apps!
