从本机0.59.10升级到0.60.5后,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Web视图是根据以下文档创建的:https://facebook.github.io/react-native/docs/custom-webview-android

CustomeWebViewManager.java的摘录:

...
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 {
...

  npmPackages:

在package.json中,我们有:

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

复制步骤

  1. 按照以下文档创建Android CustomWebView:https://facebook.github.io/react-native/docs/custom-webview-android
  2. 尝试通过执行react-native run-android
  3. 来构建Android

描述您期望发生的事情: Android应用应该像以前(0.59.10)一样构建并运行

0.60 react-native文档页面: doc page

答案 0 :(得分:0)

我们能够解决此问题。这里有一些指针:

  • 仔细阅读Autolinking文档!
  • 如果它是一个独立的模块(像我们这样),那么您 需要在以下位置包含react-native-webview: 模块的import pdfkit, mysql.connector, pprint, json, csv, datetime from exchangelib import Credentials, Account, FileAttachment from exchangelib.folders import Message, Mailbox
    Traceback (most recent call last):
      File "master_email_pdf.py", line 3, in <module>
        from exchangelib.folders import Message, Mailbox
    ImportError: cannot import name 'Message' from 'exchangelib.folders'
    (C:\Users\user\AppData\Local\Programs\Python\Python37\lib\site-packages\exchangelib\folders\__init__.py)

以及正在使用的应用的build.gradle

implementation project(":react-native-webview")

即使在使用该应用的应用中,它也应该是自动链接的。

此外,您还需要在其中添加一个名为settings.gradle的文件。 消费型应用程序:

include ':react-native-webview'
project(':react-native-webview').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-webview/android')
定义CustomWebView的Java文件中的

: 替换:

react-native.config.js

使用

const path = require('path');

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

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