世博会建设失败

Question

当前无法建立我的博览会APK，不确定原因。

我刚刚从台式机上获取了最新版本，但以前在笔记本电脑上构建时，它可以正常工作。

无论如何，当我对其进行测试时，该应用程序可以正常运行，并且可以确认我拉出了最新版本的应用程序。

iPhone的构建工作正常，但Android则失败。 这是错误日志：

我对Java不熟悉，因此无法跟踪它出了什么问题。 我的app.json文件如下所示：

{
  "expo": {
    "name": "myApp",
    "icon": "./src/images/myApp.png",
    "version": "1.1.1",
    "description": "myApp description",
    "sdkVersion": "25.0.0",
    "ios": {
      "bundleIdentifier": "com.myApp.myApp",
      "infoPlist": {
        "LSApplicationQueriesSchemes": ["whatsapp"],
        "NSCameraUsageDescription":
          "This app uses the camera"
      }
    },
    "android": {
      "package": "com.myApp.myApp",
      "versionCode": 4
    },
    "splash": {
      "image": "./assets/spashpage.png",
      "resizeMode": "cover"
    }
  }
}

有人知道原因吗？
