Question

我刚得到一个React本机项目，并且我正在尝试运行它。当我跑步时： react-native run-android ，这是我的输出。

Starting JS server...
Building and installing the app on the device (cd android && gradlew.bat installDebug)...

我已经按照facebook入门页面上的所有指示进行操作，但是此错误不断弹出。当我运行它时，我在AVD 9上运行了我的AVD。从那里开始，我尝试接受许可证。

我不知道该怎么办。我尝试过世博会，那是另一个兔子洞...请有人帮忙！谢谢！

Answer 1

Android Studio>首选项>外观和行为>系统设置> Android SDK

勾选最新的Android版本，然后单击“应用”。

此时，Android会要求您同意其许可证并安装更新的版本。

Answer 2

我读了一个答案（谢谢），可惜它没有用。我现在认为许可证不再是问题。我已经意识到该项目需要android 27，并且我已经安装了android 28，所以我尝试降级为android27。这没有用，所以我只是通过更改android / build中的ext将项目升级到android 28。 .gradle至：

ext {
    buildToolsVersion = "28.0.0"
    minSdkVersion = 16
    compileSdkVersion = 28
    targetSdkVersion = 26
    supportLibVersion = "28.0.0"
}

并将其添加到android / app / build.gradle中的

packagingOptions {
   pickFirst 'lib/x86/libc++_shared.so'
   pickFirst 'lib/x86_64/libjsc.so'
   pickFirst 'lib/arm64-v8a/libjsc.so'
   pickFirst 'lib/arm64-v8a/libc++_shared.so'
   pickFirst 'lib/x86_64/libc++_shared.so'
   pickFirst 'lib/armeabi-v7a/libc++_shared.so'
}

我还安装了Java 10.0.2，并降级为Java8。（不确定是否有所作为）

无论如何，我希望这可以帮助人们更新他们的旧项目！
