Question

我正在通过Android Studio运行react-native应用程序，并且由于Android支持依赖项而不断遇到构建错误。我已经通过Android Studio安装了必要的SDK平台和工具，但仍然遇到此错误。

Could not find com.android.support:support-v7:26.0.2.

起初我使用的是27.0.3，但是随后我注意到我的所有库都默认为26.0.2，如在构建过程中以下警告消息所述- The specified Android SDK Build Tools version (23.0.1) is ignored, as it is below the minimum supported version (26.0.2) for Android Gradle Plugin 3.0.1. Android SDK Build Tools 26.0.2 will be used.

我已经咨询了各种StackOverflow解决方案，并且每次构建都会失败。对我可能做错的事情有任何想法吗？

app / build.gradle

android {
compileSdkVersion 26
    buildToolsVersion "26.0.2"
defaultConfig {
    applicationId "com.jast"
    minSdkVersion 16
    targetSdkVersion 26
    versionCode 1
    versionName "1.0"
    ndk {
        abiFilters "armeabi-v7a", "x86"
    }
}
splits {
    abi {
        reset()
        enable enableSeparateBuildPerCPUArchitecture
        universalApk false  // If true, also generate a universal APK
        include "armeabi-v7a", "x86"
    }
}
buildTypes {
    release {
        minifyEnabled enableProguardInReleaseBuilds
        proguardFiles getDefaultProguardFile("proguard-android.txt"), "proguard-rules.pro"
    }
}
// applicationVariants are e.g. debug, release
applicationVariants.all { variant ->
    variant.outputs.each { output ->
        // For each separate APK per architecture, set a unique version code as described here:
        // http://tools.android.com/tech-docs/new-build-system/user-guide/apk-splits
        def versionCodes = ["armeabi-v7a":1, "x86":2]
        def abi = output.getFilter(OutputFile.ABI)
        if (abi != null) {  // null for the universal-debug, universal-release variants
            output.versionCodeOverride =
                    versionCodes.get(abi) * 1048576 + defaultConfig.versionCode
        }
    }
}
}

}

Answer 1

检查代码中的以下条件。

检查项目级别的build.gradle中是否有google()。如果不是，请确保jcenter()发生的位置在google()上方jcenter()处。
在应用程序级别build.gradle中，检查gradle-wrapper.properties中defaultConfig中是否具有与appcompat版本和sdkversion有关的gradle版本

Answer 2

将项目级别的gradle依赖关系更新为最新版本：

dependencies {
        classpath 'com.android.tools.build:gradle:3.2.1'
        classpath 'com.google.gms:google-services:4.2.0'

    }
