android java picasso

2022-09-03 03:11:43

我无法使用Android 9.0 Pie中的毕加索库加载图像。实际上，它适用于以下版本。它没有显示任何错误消息。有人在Github上分享了他的日志，使用

Picasso.get().setLoggingEnabled(true);

他有消息日志：

答案 1

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

根据安卓文档

指示应用是否打算使用明文网络流量，如明文 HTTP。面向 API 级别 27 或更低的应用程序的默认值为。以 API 级别 28 或更高版本为目标的应用默认为。"true""false"

当该属性设置为时，平台组件（例如，HTTP 和 FTP 堆栈、DownloadManager、MediaPlayer）将拒绝应用使用明文流量的请求。强烈建议第三方库也遵守此设置。避免明文流量的关键原因是缺乏机密性，真实性和防篡改保护：网络攻击者可以窃听传输的数据，并在不被检测到的情况下对其进行修改。链接"false"

答案 2

我知道作品的答案，但这将允许所有连接都是http而不是所有东西，我想这不是你在2018年想要的。android:usesCleartextTraffic="true"

如果您知道要进入的域并且信任它，则最好使用网络安全配置。http

在中定义 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>

查看唯一 for 及其子项。cleartextTrafficPermitted="true"secure.example.com

然后在您的，添加AndroidManifest.xmlandroid:networkSecurityConfig="@xml/network_security_config"

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