在 Android Studio 中设置 Hello, World 手表应用程序时遇到问题

问题描述

在 Android Studio 中部署包含的 Hello, World 手表应用程序的磨损版本时，我收到此错误:失败 [INSTALL_FAILED_OLDER_SDK]

When deploying the wear version of the included Hello, World watch app in Android Studio I get this error:Failure [INSTALL_FAILED_OLDER_SDK]

更新:从 Reddit 帖子中删除了有关尝试破解 L 版本的详细信息，因为这对我来说不是解决方案，而且可能会造成更多混乱.

Update: Removing details about trying a hacked version of L from the Reddit post as that was not a solution for me and it may have created more confusion.

新项目方向未触及其他所有内容.我使用 Moto Ultra 4.4 和 LG G 手表跑步.

Everything else is untouched from the New Project directions. I'm running on my Moto Ultra 4.4 and the LG G watch.

推荐答案

错误 [INSTALL_FAILED_OLDER_SDK] 是因为我正在将 Wear gradle build 部署到手机(具有不兼容的 api).要将可穿戴 gradle 版本部署到 LG G 手表，您必须启用蓝牙调试并将您的 adb 连接到手表. 然后在选择设备"对话框中选择手表.

The error [INSTALL_FAILED_OLDER_SDK] is because I was deploying the wear gradle build to the phone (which has an incompatible api). In order to deploy the wearable gradle build to the LG G watch, you have to enable bluetooth debugging and connect your adb to the watch. Then select the watch in the Choose Device dialog.
