React-native 應用程序未在 Android 4.3 上運行

Question

我的 react-native 應用程序具有以下package.json

{
  "name": "Seller",
  "version": "0.0.1",
  "private": true,
  "scripts": {
    "android": "react-native run-android",
    "ios": "react-native run-ios",
    "start": "react-native start",
    "test": "jest",
    "lint": "eslint .",
    "cleanA": "cd android && ./gradlew clean && cd ..",
    "apk": "cd android && ./gradlew assembleRelease && cd .."
  },
  "dependencies": {
    "@react-native-community/async-storage": "^1.10.3",
    "@react-native-community/geolocation": "^2.0.2",
    "@react-native-community/masked-view": "0.1.6",
    "@react-native-community/picker": "^1.4.0",
    "@react-native-firebase/app": "^6.7.1",
    "@react-native-firebase/auth": "^6.7.1",
    "@react-native-firebase/messaging": "^6.7.1",
    "@react-navigation/bottom-tabs": "^5.3.3",
    "@react-navigation/drawer": "^5.6.3",
    "@react-navigation/material-top-tabs": "^5.1.14",
    "@react-navigation/native": "^5.2.3",
    "@react-navigation/stack": "^5.2.18",
    "react": "16.11.0",
    "react-native": "0.62.2",
    "react-native-chart-kit": "^5.5.0",
    "react-native-elements": "^2.0.0",
    "react-native-gesture-handler": "~1.6.0",
    "react-native-image-picker": "^2.3.1",
    "react-native-reanimated": "~1.7.0",
    "react-native-safe-area-context": "0.7.3",
    "react-native-screens": "~2.2.0",
    "react-native-svg": "^12.1.0",
    "react-native-tab-view": "^2.14.0",
    "react-native-vector-icons": "^6.6.0",
    "react-redux": "^7.2.0",
    "redux": "^4.0.5",
    "redux-devtools-extension": "^2.13.8",
    "redux-thunk": "^2.3.0"
  },
  "devDependencies": {
    "@babel/core": "^7.6.2",
    "@babel/runtime": "^7.6.2",
    "@react-native-community/eslint-config": "^0.0.5",
    "babel-jest": "^24.9.0",
    "eslint": "^6.5.1",
    "jest": "^24.9.0",
    "metro-react-native-babel-preset": "^0.58.0",
    "react-test-renderer": "16.11.0"
  },
  "jest": {
    "preset": "react-native"
  }
}

它在 Android 5.0 及更高版本上運行良好。 最低 SDK 版本為 16。但是，它不在 Android 4.3 上運行

異常跟蹤如下：

    at dalvik.system.NativeStart.main(Native Method)

我試圖在android/build.gradle compileSdkVersion 但是在那之后，我在依賴包中獲得了編譯器，因為它們沒有使用 Java 1.6 進行編譯。

解決此問題的步驟是什么？

這可能是一個 multidex 問題，因為在 android 5.0 及更高版本上默認啟用了 multidex。 如果您運行的 APK < 21 並且您的應用程序有超過 64,000 個方法，您需要在 android 中啟用 multidex。 請參閱以下文檔 -
