从 react-native 升级0.59.100.60.5我们在构建 Android 时收到此错误:

/workspace/mobile-custom-webview/mobile-custom-webview/android/src/main/java/invisionapp/customwebview/CustomWebViewManager.java:27: error: package com.facebook.react.
views.webview does not exist
import com.facebook.react.views.webview.ReactWebViewManager;
                                       ^
/workspace/mobile-custom-webview/mobile-custom-webview/android/src/main/java/invisionapp/customwebview/CustomWebViewManager.java:36: error: cannot find symbol
public class CustomWebViewManager extends ReactWebViewManager {

自定义 webview 是根据文档创建的:https://facebook.github.io/react-native/docs/custom-webview-android

摘自CustomeWebViewManager.java:

...
import com.facebook.react.views.webview.ReactWebViewManager;
import javax.annotation.Nullable;

import java.util.Map;

@ReactModule(name = CustomWebViewManager.REACT_CLASS)
public class CustomWebViewManager extends ReactWebViewManager {
...

    "react": "16.8.6",
    "react-native": "0.60.5",
    "react-native-webview": "6.8.0"
  },

重现步骤

  1. 按照文档创建一个 Android CustomWebView:https://facebook.github.io/react-native/docs/custom-webview-android
  2. 尝试通过做来构建Androidreact-native run-android

描述您期望发生的事情:Android 应用程序应该像以前一样构建和运行 (0.59.10)

我们能够解决这个问题。这里有几个指针:

  • 仔细阅读自动链接文档!
  • 如果它是一个独立的模块(就像我们的情况一样),那么你需要将 react-native-webview 包含在:build.gradle模块的
implementation project(":react-native-webview")

settings.gradle消费应用程序中

include ':react-native-webview'
project(':react-native-webview').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-webview/android')

即使在消费应用程序中,它也应该是自动链接的。

此外,您需要添加一个react-native.config.js在消费应用程序中调用的文件:

const path = require('path');

  module.exports = {
   dependencies: {
     'mobile-custom-webview': {
       root: path.resolve('../mobile-custom-webview'),
     },
   },
 };

在定义 CustomWebView 的 Java 文件中:替换:

import com.reactnativecommunity.webview.RNCWebViewPackage;

import com.reactnativecommunity.webview.RNCWebViewManager;

最后,一些方法有不同的签名,例如: ReactWebView --> RNCWebView
