React Native - java.lang.RuntimeException：找不到SDK位置。使用local.properties中的sdk.dir定义位置

Question

React Native入门。我确实安装了Android SDK，Java SDK和Android依赖项。在终端上运行演示应用程序时收到以下错误。

我的Galaxy Emulator正在运行：

~ emulator @galaxy
HAXM is working and emulator runs in fast virt mode
emulator: UpdateChecker: skipped version check

现在我运行它：

~ react-native run-android
Starting JS server...
Building and installing the app on the device (cd android && ./gradlew installDebug)...
Failed to notify ProjectEvaluationListener.afterEvaluate(), but primary configuration failure takes precedence.
java.lang.RuntimeException: SDK location not found. Define location with sdk.dir in the local.properties file or with an ANDROID_HOME environment variable.

Answer 1

在Android Studio中：文件 - ＆gt;项目结构 - ＆gt; Android SDK位置

复制Android SDK路径

1. 在Project_Name中 - ＆gt; Android - ＆gt;创建文件local.properties
2. 打开local.properties。
3. 写sdk.dir = / Users / Ashok / Library / Android / sdk
4. 保存。
来自项目根目录react-native run-android的
5. 。

Answer 2

以下是我在Mac OSX上使用Android进行本地反应的方法：

1. 下载android studio并通过它更新android sdk， https://developer.android.com/studio/index.html#downloads

2. 在.base_profile中添加路径 export ANDROID_HOME=/Users/UserName/Library/Android/sdk export PATH=$PATH:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools

3. 将local.properties文件放在project_name/android/文件夹中。

4. 修改local.properties，然后在其中添加sdk.dir=/Users/UserName/Library/Android/sdk。

5. 运行android命令以更新所需的包。 对于RN 0.32，其

   • tools / sdk build tools 23.0.1
   • Android 6.0（API 23）
   • 附加功能
   • Android支持库

6. 运行android studio或android avd命令以打开模拟器

7. 执行react-native run-android
8. 一旦您在Android中看到应用程序的红色屏幕，请执行react-native start以触发桥接服务器

Answer 3

如果您使用的是Android Studio，请按照以下步骤操作。

• 转到文件＆gt;项目结构＆gt;
• 在“SDK位置”标签中添加“位置路径”，然后重试。

Answer 4

在没有android studio的Linux中：

首先检查：您已经下载并解压缩了android SDK并运行了android命令来安装实际的开发SDK？

在建造和运行时仍未找到它。然后问题可能是文件local.properties需要在gradle内容的同一目录内，以便gradle在构建和运行adb时找到它。

对于我的项目使用我需要将local.properties文件放到Myprojectname / android /文件夹中，它开始工作。

由于我已将SDK解压缩到下载文件中的路径为：sdk.dir = / home / USER / Downloads / android-sdk-linux

Answer 5

将android studio路径添加到您的环境变量

nano ~/.bash_profile 

添加以下行：

 export ANDROID_HOME=/YOUR_PATH_TO/android-sdk
 export PATH=$ANDROID_HOME/platform-tools:$PATH
 export PATH=$ANDROID_HOME/tools:$PATH
