我需要帮助才能在 Windows 上从 Github 运行 React 本机应用程序

Question

我需要帮助才能在我的手机上运行这个 React 本机应用程序。 https://github.com/minhtc/audiobookapp Expo Go 安装在我的安卓手机上。 当我运行以下命令时：

• npm 安装
• npx react-native run-android

这就是我得到的。 你能帮帮我吗？

Answer 1

在这种情况下，我认为您项目中的库使用 21 的 minSdkVersion。而您的项目 minSdkVersion 是 16。 这些版本之间的不兼容导致了这个问题。

我认为如果您将项目 minSdkVersion 增加到 21，问题就解决了。 为此，打开 android 根目录中的根 Gradle 文件，在本节中将 16 更改为 21：

buildscript {
    ext {
        ...
        minSdkVersion = 16 --> minSdkVersion = 21
        ...
    }
}
