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.有人用Github分享了他的日志

Picasso.get().setLoggingEnabled(true);

他有消息日志:

Answer 1

尝试android:usesCleartextTraffic="true"在Manifest文件的应用程序标记中使用!因为我使用Android Volley面临同样的问题!

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.默认值是true".当属性设置为"false"时,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.强烈建议第三方图书馆遵守此设置.避免明文流量的关键原因是缺乏机密性,真实性和防止篡改:网络攻击者可以窃听传输的数据并在不被检测的情况下对其进行修改. 链接

我知道答案是android:usesCleartextTraffic="true"有效的,但是这将允许所有连接都是http 而不是一切,我想这不是你想要的2018年.

如果您知道您正在进入的域http并且您信任它,那么最好使用网络安全配置.

在中定义一个xml文件 res/xml/network_security_config.xml

<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
    <domain-config cleartextTrafficPermitted="true">
        <domain includeSubdomains="true">secure.example.com</domain>
    </domain-config>
</network-security-config>

cleartextTrafficPermitted="true"只看到secure.example.com它和它的潜艇.

然后在你的AndroidManifest.xml,添加android:networkSecurityConfig="@xml/network_security_config"

您可以添加多个域,具有多个配置,确保其中一些域为https或相反.看起来更安全恕我直言.
