android - 如何创建一个新的 Android Wear 项目并在设备上运行它？

Question

这个问题说明了一切。不幸的是，它不像创建一个新项目、连接一个设备并按下运行按钮那么简单。以下是详细信息：

我正在尝试创建一个仅适用于 Wear OS的新应用（即不支持手机或平板电脑）。API 级别设置为 28 (Android 8)，带有空白磨损活动。完成新项目向导后，Android Studio 会以闪亮的红色字母打印以下欢迎消息：

Manifest merger failed : Attribute application@appComponentFactory value=(android.support.v4.app.CoreComponentFactory) from [com.android.support:support-compat:28.0.0] AndroidManifest.xml:22:18-91
    is also present at [androidx.core:core:1.0.0] AndroidManifest.xml:22:18-86 value=(androidx.core.app.CoreComponentFactory).
    Suggestion: add 'tools:replace="android:appComponentFactory"' to <application> element at AndroidManifest.xml:9:5-35:19 to override.

按照建议并添加tools:replace="android:appComponentFactory"到<application>AndroidManifest.xml 中的元素将错误消息更改为：

这并没有让它变得更好......恢复清单修改和谷歌搜索根本原因（清单合并失败）似乎是更好的方法，这导致了这里的答案，建议在以下位置添加以下两行gradle.properties：

android.useAndroidX=true
android.enableJetifier=true

最后它建立了！但是，该应用程序在尝试在手表上运行时会立即崩溃：

所以这也不是正确的解决方法......

您有什么想法吗？创建一个新项目并在设备上运行它应该可以开箱即用，但似乎有些东西严重损坏了。

顺便提一句。使用 Android Studio 版本 3.2.1，带有 SDK 平台工具 29.0.2 和 SDK 工具 26.1.1。安装了 SDK 21 到 29。

任何建议如何让一个空的磨损项目运行表示赞赏，谢谢。

看起来依赖关系有些问题。实际上，我从来没有遇到过这样的问题，第一个建议是更新 andorid studio，然后创建新的 wear os 项目并尝试在不做任何更改的情况下运行它。

如果这没有帮助，其他一些解决方案可能是删除磨损类的使用和所有磨损特定的依赖项，只留下

< 使用功能 android:name="android.hardware.type.watch" />

在清单文件中，然后尝试运行默认的 Android 活动。
