“无法解决:com.android.support:support-v4:26.0.0”和 Gradle 同步上的其他类似错误

新手上路,请多包涵

我刚刚为 Android Mobile wear 创建了一个新的 Android Studio 项目。最初的 gradle 构建失败,因为我收到了几个错误-

Error: Failed to resolve: com.android.support:support-v4:26.0.0

Error: Failed to resolve: com.android.support:percent:26.0.0

Error: Failed to resolve: com.android.support:recyclerview-v7:26.0.0

Error: Failed to resolve: com.android.support:support-annotations:26.0.0

对于每个错误,我都可以选择 Install repository and sync project ,但是当我点击它时没有任何反应。我花了几个小时试图找出为什么会出现这些错误,但我找不到任何解决方案。有谁知道如何解决这些非常令人沮丧的错误?谢谢!

我确定我的 Android Studio 版本已更新,并且已安装所有支持存储库和 API。 在此处输入图像描述

我的项目给我这些错误的原因是因为我为 Android 平台 26 创建了项目。但是,Wear 目前不支持 26,并且必须更改 targetcompile build.gradle 的 wear 模块中的 SDK 版本为 25。

链接到 Android 开发人员文档 - https://developer.android.com/training/wearables/apps/creating.html#setting-up-a-phone

build.gradle(磨损)

 apply plugin: 'com.android.application'

android {
compileSdkVersion 25
buildToolsVersion "26.0.1"

defaultConfig {
    applicationId "com.georgeberdovskiy.findmyphone"
    minSdkVersion 25
    targetSdkVersion 25
    versionCode 1
    versionName "1.0"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'),       'proguard-rules.pro'
    }
    }
}

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.google.android.support:wearable:2.0.3'
provided 'com.google.android.wearable:wearable:2.0.3'
compile 'com.google.android.gms:play-services-maps:11.0.4'
compile 'com.google.firebase:firebase-core:11.0.4'
compile 'com.google.firebase:firebase-database:11.0.4'
compile 'com.google.android.gms:play-services-wearable:11.0.4'

}

apply plugin: 'com.google.gms.google-services'

我只需要在磨损模块中将编译和目标 SDK 版本更改为 25。对于移动模块,我将它们保留为 26。

我没有 Android wear 项目,但是当我想将现有项目的支持库版本升级到 26.0.0 时,我遇到了同样的问题。从 26.0.0 开始,支持库可通过 Google 的 Maven 存储库获得。所以我不得不将存储库添加到我的构建中。渐变文件。

 allprojects {
  repositories {
      jcenter()
      maven {
          url "https://maven.google.com"
      }
  }
}
