在 Android Studio 中编译简单的可穿戴应用程序 - 未找到 WatchActivity

问题描述

我按照此链接中的说明创建了一个简单的移动Android Studio 中的/wearable 应用.但是，它不会识别任何特定于可穿戴 SDK 的类，从而给出错误无法解析符号 ______".此链接上的屏幕截图就是我所看到的.

I followed the instructions at this link to create a simple mobile/wearable app in Android Studio. However, it won't recognize any of the classes specific to the wearable SDK, giving the error "cannot resolve symbol ______". The screenshot at this link is what I am seeing.

以下是我的 build.gradle 文件:

The following is my build.gradle file:

apply plugin: 'com.android.application'
android {
    compileSdkVersion 20
    buildToolsVersion '20.0.0'
    defaultConfig {
         applicationId 'com.example.lsykora.androidwearwidget'
         minSdkVersion 'L'
         targetSdkVersion 'L'
         versionCode 1
         versionName '1.0'
}
buildTypes {
    release {
        runProguard false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-    rules.pro'
    }
}
productFlavors {}
}
dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
// You must install or update the Support Repository through the SDK manager to use      this dependency.
// You must install or update the Support Repository through the SDK manager to use this dependency.
compile 'com.android.support:support-v13:+'
compile 'com.google.android.support:wearable:+'
compile 'com.google.android.gms:play-services-wearable:+'
}

我已经使用 SDK 管理器安装了所有 SDK，并尝试修改 build.gradle 文件中的最小、目标和编译 SDK，将它们设置为 19、20 或 Android-L，但我有相同的结果 - 由于这些无法识别的类，程序将无法编译.任何输入表示赞赏！谢谢

I have installed all SDK's using SDK manager and I have tried tinkering with the minimum, target, and compile SDK's in the build.gradle file, setting them to 19, 20, or Android-L, but I'm having the same results - program won't compile because of these unrecognized classes. Any input is appreciated! Thanks

推荐答案

不要扩展 WatchActivity(该类实际上并不存在).

Don't extend WatchActivity (that class doesn't actually exist).

Android Wear 活动的基类只是标准的Activity.

The base class for Android Wear activities is just the standard Activity.

(此外，如果您使用的是 Android Studio 0.8.0，请更新到 0.8.1 -- 0.8.0 的模板中存在错误，并使用 extend WatchActivity 创建新活动，即实际上无效).

(Also, if you're using Android Studio 0.8.0, update to 0.8.1 -- 0.8.0 has a bug in its templates and creates new Activities using extend WatchActivity, which is actually invalid).
