Android WebView 加载失败（net::ERR_CLEARTEXT_NOT_PERMITTED）

解锁正确姿势
首先保证App申明了网络权限

  1. <uses-permission android:name="android.permission.INTERNET" />

解决办法（1）：
在Application中打开一个开关

  1. <manifest ...>
  2.    <application
  3.        ...
  4.        android:usesCleartextTraffic="true"
  5.        ...>
  6.        ...
  7.    </application>
  8. </manifest>
  1. 解决办法（2）：<br />res 下新建 xml 目录，创建文件：network_security_config.xml ，内容如下：

<?xml version=”1.0” encoding=”utf-8”?>

  1. 在 AndroidManifest.xml 的 application 标签添加配置：

… 

  1. 解决办法（3）：【推荐】<br />服务器和本地应用都改用 https
  3. 解决办法（4）：<br />targetSdkVersion 降级回到 27

  3. ### gradle使用dokka插件出现Exception while loading package-list from ExternalDocumentationLinkImp
  5. 请求不到 package-list，翻墙即可解决<br />不翻墙的解决方案如下：

dokka { outputFormat = ‘javadoc’ outputDirectory = javadoc.destinationDir

  1. configuration {
  2.     externalDocumentationLink {
  3.         noJdkLink = true
  4.         noStdlibLink = true
  5.         noAndroidSdkLink = true
  7.         url = new URL("https://developer.android.google.cn/reference/")
  8.         packageListUrl = new URL("https://developer.android.google.cn/reference/package-list")
  9.     }
  10. }

}

  4. ### More than one file was found with OS independent path 'lib/armeabi/xxxx.so'
  6. so 重复

// 在build.gradle(Module: app)里面，加上一句： packagingOptions { exclude ‘lib/armeabi/xxx.so’ // 或者 pickFirst ‘lib/armeabi/xxx.so’ }

  3. ### Go to the documentation to learn how to Fix dependency resolution errors.
  5. 依赖库版本冲突<br />解决方法 1：

subprojects { configurations.all { … resolutionStrategy.eachDependency { details -> if (details.requested.group == ‘androidx.annotation’) { details.useVersion “1.1.0” } … } } }

  5. ### A POM cannot have multiple artifacts with the same type and classifier
  • What went wrong: Execution failed for task ‘:emao-lib:lib-base:uploadToLocalSnapshot’.

    Could not publish configuration ‘archives’ A POM cannot have multiple artifacts with the same type and classifier. Already have MavenArtifact lib-base:aar:aar:null, trying to add MavenArtifact lib-base:aar:aar:null. ```

原因：上传的 artifacts 中包含多个 aar
