React-Native-无法通知项目评估监听器

Question

使用 gradle 4.3 在 Windows 7 上构建 react-native 应用程序，我收到以下错误，不确定问题是什么，我们将不胜感激。

C:\Users\username\AwesomeProject>react-native run-android

Make sure you have an Android emulator running or a device connected and have
set up your Android development environment:

Answer 1

升级你的 build.gradle 项目文件； com.android.tools.build:gradle 版本从 2.2.3 使用如下：

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.3.3'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

您可能会也可能不会遇到此问题，请更新您的构建工具。

The SDK Build Tools revision (23.0.1) is too low for project ':app'. Minimum required is 25.0.0

解决方案：在您的项目中更新 /app/build.gradle 如下：

android {
    compileSdkVersion 25
    buildToolsVersion "25.0.1"
