react-native run-android build error语言 - 无法解决:com.android.supp

Question

我正在通过Android Studio运行react-native应用程序，并且我一直遇到android支持依赖项的构建错误。我通过Android Studio安装了必要的SDK平台和工具，但我仍然遇到此错误。

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

起初我使用的是 27.0.3，但后来我注意到我的所有库都默认为 26.0.2，如构建过程中的以下警告消息所述 - 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.

我咨询了各种StackOverflow解决方案，每次构建都失败。关于我可能做错了什么的任何想法？

    abi {
        reset()

        universalApk false  // If true, also generate a universal APK
        include "armeabi-v7a", "x86"
    }

}
// 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:

        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。

• 检查您的项目级别 build.gradle 中是否有google()。如果没有，请确保jcenter()发生的位置google()高于jcenter()。
• 在应用级 build.gradle 中检查gradle-wrapper.properties是否具有与 appcompat 版本和 sdk defaultConfig version 相关的相应 gradle 版本
。

Answer 2

将项目级 gradle 依赖项更新到最新版本：

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