Question

我想运行我的第一个React本机项目，我使用linux，我想运行android项目。我安装了最新版本的android studio并安装了android SDK，并在shell配置中导出了PATH。我使用react-native init albums创建了项目，并使用android studio打开了albums/android，android studio自动安装gradle并没有出错。我用android 4.0.3创建一个AVD并运行它。我想使用react-native run-android运行我的项目，但出现错误：

我如何解决此错误？

Answer 1

问题在于您的应用程序的目标是Android的16 API级别，并且您试图在一个较小的API中运行它（15）。尝试更改清单中的API级别，但是，如果您想运行React Native Apps，我认为较小的Android API是16。

Answer 2

根据this页：

Supported target operating systems are >= Android 4.1 (API 16) ...

您打算使用API 15内置到设备中。

Answer 3

将以下方法添加到build.gradle中（在allprojects方法之前）

子项目{ project.configurations.all { resolutionStrategy.eachDependency {详细信息-> 如果（details.requested.group =='com.android.support' &&！details.requested.name.contains（'multidex'））{ details.useVersion“ 28.0.0” } } } }
在package.json中将您的React本机版本更改为0.57.3
