| <p>Google Play services 5.0 is currently being rolled out to the world. |
| We usually wait to release the Google Play services SDK until the rollout completes. |
| This ensures that your newly-updated apps can run on the most devices as possible.</p> |
| |
| <p>However, if you want to develop for Android Wear now, complete the following steps to get |
| special access to all the things you need to start developing, without waiting for the rollout to |
| complete.</p> |
| |
| <p class="warning"><b>Warning</b>: Do not publish any apps that are built with Google Play services |
| SDK 5.0 until the rollout is completed over the coming days. Your apps will break on most user |
| devices, which will degrade your apps’ user experience. We’ll publish an update to the |
| <a href="http://android-developers.blogspot.com/">Android Developer blog</a> when the rollout is done. |
| </p> |

| and handheld devices. To get the new SDK that is compatible with the Google Play services |
| APK that you just installed, follow these steps: </p> |
| |
| <p class="note"><b>Note:</b> We highly recommend you use Android Studio for Wear development.</p> |
| <ol> |
| <li>Start AVD Manager.</li> |
| <li>Update the Android SDK Tools and Platform-tools to versions 23 and 20 respectively.</li> |
| <li>Click <b>Tools > Manage Add-on Sites > User Defined Sites</b>.</li> |
| <li>Click <b>New</b>, enter |
| <code>https://dl-ssl.google.com/android/repository/addon-play-services-5.xml</code> into the |
