Android Studio 代码不适用于 Android 9.0 版

Question

请我的 Android 应用程序在任何 Android 应用程序版本中都能正常工作，但在 android 9.0 上不能工作？？ 在模拟器上从android studio运行代码时没有错误显示..

当在 android 8.0 或更低版本上运行时，它运行良好...但问题出在 9 或更高版本上？？

Answer 1

只需将以下行放在应用程序标签下的清单中并尝试

<uses-library android:name="org.apache.http.legacy" android:required="false"/>

如果不起作用，请尝试在应用程序标记下添加以下行

android:usesCleartextTraffic="true

，即使它不起作用尝试添加

android:networkSecurityConfig="@xml/network_security_config

在 network_security_config.xml 所在的应用程序标记中

<?xml version="1.0" encoding="utf-8"?> <network-security-config> <base-config cleartextTrafficPermitted="true" /> </network-security-config>

在 res 目录下创建 xml，然后在 xml 文件夹中创建 network_security_config.xml
