Question

我无法使用Android 9.0
Pie中的Picasso库加载图像。实际上，它适用于以下版本。它没有显示任何错误消息。有人使用共享了他在Github上的日志

Picasso.get().setLoggingEnabled(true);

他有消息日志：

Answer 1

尝试android:usesCleartextTraffic="true"在清单文件的应用程序标记中使用！由于我在使用Android
Volley时遇到同样的问题！

根据Android文档

指示应用程序是否打算使用明文网络流量，例如明文HTTP。适用于应用的默认值，该值目标 API级27或更低的 是"true"。目标
API级别为28或更高的应用 默认为"false"。

当属性设置为时"false"，平台组件（例如HTTP和FTP堆栈，DownloadManager，MediaPlayer）将拒绝应用程序使用明文流量的请求。强烈建议第三方库也采用此设置。避免明文通信的主要原因是缺乏机密性，真实性和防篡改保护：网络攻击者可以窃听所传输的数据，也可以对其进行修改而不会被发现。
