Android 9.0（Pie）不支持异步任务

Question

我正在处理我的代码，它在版本8（Oreo）上运行良好。之后，我收到了安卓v9.0（Pie）的更新，应用程序突然停止工作。检查后，我发现我的异步任务出现了以下错误：

有人可以帮我解决这个问题吗？因为之前它一直很正常地工作。谢谢！

Java反射在9.0中受到限制，请查看：https://developer.android.com/about/versions/pie/restrictions-non-sdk-interfaces - Atiq Ur Rehman

错误很明显：java.lang.ClassNotFoundException: Didn't find class "org.apache.commons.logging.LogFactory"，您正在尝试加载一个来自apache commons logging的类，但失败了。检查您的代码，并不再使用此库中的类。 - Robert

Answer 1

我之前也遇到了同样的问题，但在我的清单文件中添加以下代码后，问题得以解决。

您可以参考以下网址： https://developer.android.com/about/versions/pie/android-9.0-changes-28

manifest.xml

<application
        ...
         android:usesCleartextTraffic="true"
       ...>

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

Answer 2

如何在androidx中更新现有项目。

无需添加额外的权限和代码、依赖等。

0.1）：将版本更改为compileSdkVersion 29

0.2）: 重构 -> 迁移到androidX

只需将以下代码添加到项目“ASDF”中：

1）：添加XML目录，

1.1）：在XML中添加以下代码，代码如下：

<application

<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
<base-config cleartextTrafficPermitted="true">
<trust-anchors>
<certificates src="system"/>
</trust-anchors>
</base-config>
</network-security-config>

>

2）：在清单文件中添加以下代码：

2.1）：在应用程序标签（manifest->application）内添加以下代码：

android:networkSecurityConfig="@xml/network_security_config"

2.2): 在应用程序标签(manifest->application)之外添加以下代码：

<application>

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

</application>

开心点，和我分享你的反馈。谢谢！
