error: cannot find symbol BuildConfig.DEBUG

Question

我已经从 expo 管理项目退出到裸工作流项目。但是当我尝试运行这个项目时，它发现

错误

E:\Mnor Project 1\ejected\android\app\src\main\java\com\minorproject\MainApplication.java:40: error: cannot find symbol
      return BuildConfig.DEBUG;

这是我在 MainAplication.java

中的进口商品

package com.minorproject;

import android.app.Application;
import android.content.Context;
import android.net.Uri;

import com.facebook.react.PackageList;
import com.facebook.react.ReactApplication;
import com.facebook.react.ReactInstanceManager;
import com.facebook.react.ReactNativeHost;
import com.facebook.react.ReactPackage;
import com.facebook.react.shell.MainReactPackage;
import com.facebook.soloader.SoLoader;
import com.minorproject.generated.BasePackageList;

import org.unimodules.adapters.react.ReactAdapterPackage;
import org.unimodules.adapters.react.ModuleRegistryAdapter;
import org.unimodules.adapters.react.ReactModuleRegistryProvider;
import org.unimodules.core.interfaces.Package;
import org.unimodules.core.interfaces.SingletonModule;
import expo.modules.constants.ConstantsPackage;
import expo.modules.permissions.PermissionsPackage;
import expo.modules.filesystem.FileSystemPackage;
import expo.modules.updates.UpdatesController;

这是我在 MainActivity.java

中的输入

package com.minorproject;

import android.os.Bundle;

import com.facebook.react.ReactActivity;
import com.facebook.react.ReactActivityDelegate;
import com.facebook.react.ReactRootView;
import com.swmansion.gesturehandler.react.RNGestureHandlerEnabledRootView;

import expo.modules.splashscreen.SplashScreen;
import expo.modules.splashscreen.SplashScreenImageResizeMode;

这是我的 package.json

{
  "expo": {
    "name": "minor-project",
    "slug": "minor-project",
    "version": "1.0.0",
    "orientation": "portrait",
    "icon": "./assets/icon.png",
    "splash": {
      "image": "./assets/splash.png",
      "resizeMode": "contain",
      "backgroundColor": "#ffffff"
    },
    "updates": {
      "fallbackToCacheTimeout": 0
    },
    "assetBundlePatterns": ["**/*"],
    "ios": {
      "supportsTablet": true,
      "bundleIdentifier": "com.akshay2739.minorproject"
    },
    "web": {
      "favicon": "./assets/favicon.png"
    },
    "sdkVersion": "38.0.0",
    "platforms": ["ios", "android", "web"],
    "android": {
      "package": "com.akshay2739.minorproject"
    }
  }
}

我曾尝试导入 import com.facebook.react.BuildConfig;，但它随后构建但在我运行应用程序时崩溃。

Answer 1

Breaking changes On Android scoped SplashScreen objects into separate singletons sub-package. (#10294 by @bbarthec) Updated @expo/configure-splash-screen to v0.2.0.

降级很容易：

npm uninstall -g @expo/configure-splash-screen && npm install -g @expo/configure-splash-screen@0.2.0

Answer 2

替换行import expo.modules.splashscreen.SplashScreen; import expo.modules.splashscreen.singletons.SplashScreen; 在 android 文件夹的 MainActivity.java 文件中。

Answer 3

我在 expo repo 上的未解决问题上搜索了它。我发现了这个悬而未决的问题。
