java - SDK设置失败 : Error:Module 'app' : platform 'Google Inc.:Google APIs:21' not found

Question

Failed to set up SDK: Error:Module 'app': platform 'Google Inc.:Google APIs:21' not found.

完全不知道为什么这不起作用。尝试将我的 SDK 更新到 23 但意识到我不准备处理所有新的弃用等，所以我在 Mercurial 上恢复到旧版本。我几乎没有做任何其他事情，回归应该已经解决了所有问题。不幸的是，我无法连接我的应用程序并构建它。我什至从头开始重新安装了 Android Studio，但我继续收到相同的警告，我的应用程序根本无法构建。可能出了什么问题？

这是我的构建 gradle:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 'Google Inc.:Google APIs:21'
    buildToolsVersion '21.1.2'

    defaultConfig {
        applicationId "com.elgami.customizer"
        minSdkVersion 14
        targetSdkVersion 21
    }

    buildTypes {
        release {
            minifyEnabled false
            //runProguard false
            //proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }
}

repositories {
    mavenCentral()
    maven { url "https://jitpack.io" }
}

dependencies {
    compile 'com.ogaclejapan.smarttablayout:library:1.5.0@aar'
    compile 'com.github.antonyt:InfiniteViewPager:v1.0.0'
    compile 'com.android.support:appcompat-v7:22.2.0'
    // recyclerview
    compile 'com.android.support:recyclerview-v7:23.1.1'
    // google analytics
    compile 'com.google.android.gms:play-services-analytics:8.3.0'
    // pager sliding strip
    compile 'com.astuetz:pagerslidingtabstrip:1.0.1'
    // http library (for using beanstream REST)
    compile 'org.apache.httpcomponents:httpclient-android:4.3.5.1'
    // amaazon S3 uploads
    compile 'com.amazonaws:aws-android-sdk-s3:2.1.+'
    // paypal purchasing
    compile files('libs/PayPalAndroidSDK-2.7.1.jar')
    // Module dependency on ParseLoginUI library sources
    compile project(':ParseLoginUI')
    // Parse libs
    compile files('libs/ParseCrashReporting-1.9.2.jar')
    compile files('libs/Parse-1.9.1.jar')
    compile files('libs/ParseFacebookUtilsV4-1.9.1.jar')
    // android support v4
    compile files('libs/android-support-v4.jar')
    // facebook SDK
    compile 'com.facebook.android:facebook-android-sdk:4.1.0'
    //butterknife
    compile 'com.jakewharton:butterknife:6.1.0'
    // Subsampling-scale-image-view (for templating)
    //compile 'com.davemorrissey.labs:subsampling-scale-image-view:3.1.4'
    compile files('libs/AppRater.jar')
}

您可以使用 compileSdkVersion 21 代替您的。

    android {
    compileSdkVersion 21
    buildToolsVersion '21.1.2'

    defaultConfig {
        applicationId "com.elgami.customizer"
        minSdkVersion 14
        targetSdkVersion 21
    }

    buildTypes {
        release {
            minifyEnabled false
            //runProguard false
            //proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }
}
