这是我的 Gradle 文件

    apply plugin: 'com.android.application'

android {
    compileSdkVersion 19
    buildToolsVersion "23.0.0 rc2"

    defaultConfig {
        applicationId "lk.lankahomes.baman.srilankatemples"
        minSdkVersion 16
        targetSdkVersion 21
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    compile 'com.android.support:appcompat-v7:21.0.1'
    compile 'com.android.support:recyclerview-v7:21.0.1'
}

谁能帮我解决这个问题，谢谢。

Answer 1

我认为 buildToolsVersion "23.0.0 rc2" 行导致了问题。

改为buildToolsVersion "21.0.1"

或尝试

compileSdkVersion 21
buildToolsVersion "22.0.1"

和

compile 'com.android.support:appcompat-v7:22.2.0'

是的，sharj 所说的也是正确的，您可能缺少构建工具

Answer 2

这是因为21.0.1 支持库 不存在 .

您可以在 build.gradle 中使用其中之一：

dependencies{

  //it requires compileSdkVersion 23
  compile 'com.android.support:appcompat-v7:23.2.0'
  compile 'com.android.support:appcompat-v7:23.1.1'
  compile 'com.android.support:appcompat-v7:23.1.0'
  compile 'com.android.support:appcompat-v7:23.0.1'
  compile 'com.android.support:appcompat-v7:23.0.0'

  //it requires compileSdkVersion 22
  compile 'com.android.support:appcompat-v7:22.2.1'
  compile 'com.android.support:appcompat-v7:22.2.0'
  compile 'com.android.support:appcompat-v7:22.1.1'
  compile 'com.android.support:appcompat-v7:22.1.0'
  compile 'com.android.support:appcompat-v7:22.0.0'

  //it requires compileSdkVersion 21
  compile 'com.android.support:appcompat-v7:21.0.3'
  compile 'com.android.support:appcompat-v7:21.0.2'
  compile 'com.android.support:appcompat-v7:21.0.0'

}

同样的考虑也适用于 com.android.support:recyclerview-v7

Answer 3

我遇到了类似的问题并安装了 android SDK 构建工具 -v23.0.1 并参考了 Android 安装指南 https://facebook.github.io/react-native/docs/android-setup.html#content

但无法找到 "Android support repository"，对于最新版本的 SDK 管理器-选项已更改为 "Local maven repository for support libraries"。
