Android，CLEARTEXT communication not enabled for client

时间：2025-02-13 06:56:06

后台接口使用的是http协议，执行http请求时报错：

W/WebSocketConnection: onFailure()
    java.net.UnknownServiceException: CLEARTEXT communication not enabled for client

        at java.lang.Thread.run(Thread.java:923)

原因：
从Android 9（API级别28）开始，默认情况下禁用明文传输支持。

解决：在创建OkHttpClient的时候添加的连接规范配置，如：

OkHttpClient okHttpClient = new OkHttpClient.Builder()
.connectionSpecs(Arrays.asList(ConnectionSpec.CLEARTEXT))
.build();

然后执行时，报错：

解决：
在文件中的 <application> 标签中添加 android:usesCleartextTraffic="true" 属性，比如：

    <application android:name=".ApplicationContext"
                 android:icon="@mipmap/ic_launcher"
                 android:label="@string/app_name"
                 android:supportsRtl="true"
                 tools:replace="android:allowBackup"
                 android:allowBackup="false"
                 android:theme="@style/"
                 android:largeHeap="true"
                 android:usesCleartextTraffic="true">

再次发起http请求，可以正常执行。

如何在生产环境只使用https，但在debug模式可以使用http

如何在生产环境中只使用https，不可以使用http，但在debug调试模式下允许使用明文？
在中配置：

// Put this in your buildtypes debug section:
manifestPlaceholders = [usesCleartextTraffic:"true"]

// Put this in your buildtypes release section
manifestPlaceholders = [usesCleartextTraffic:"false"]
