android版本的demo点击强制更新，提示undefined

[geeker-cmc]

以下为项目package.json配置 { "name": "Test", "version": "0.0.1", "private": true, "scripts": { "android": "react-native run-android", "ios": "react-native run-ios", "lint": "eslint .", "start": "react-native start", "test": "jest" }, "dependencies": { "react": "18.2.0", "react-native": "0.73.2", "react-native-update": "^9.1.6" }, "devDependencies": { "@babel/core": "^7.20.0", "@babel/preset-env": "^7.20.0", "@babel/runtime": "^7.20.0", "@react-native/babel-preset": "0.73.19", "@react-native/eslint-config": "0.73.2", "@react-native/metro-config": "0.73.3", "@react-native/typescript-config": "0.73.1", "@types/react": "^18.2.6", "@types/react-test-renderer": "^18.0.0", "babel-jest": "^29.6.3", "eslint": "^8.19.0", "jest": "^29.6.3", "prettier": "2.8.8", "react-test-renderer": "18.2.0", "typescript": "5.0.4" }, "engines": { "node": ">=18" } } jdk 17

按照文档的流程集成，使用手动集成的代码，android使用强制更新后有以下提示。 ![Uploading 151705290603_.pic.jpg…]()
