我有一个应用程序，现在我要发布它。 我创建了一个 apk 文件并安装了它，但是当我向服务器发送登录请求时，它返回 null..
奇怪的是，当我使用调试版本启动应用程序时，它工作正常。 该问题仅发生在发布模式下。所以我在阅读这篇文章
后认为问题来自于proguard这是我到目前为止所做的。
如有任何帮助，我们将不胜感激...
这是我的 build.gradle 文件。

这是我的 proguard-rules.pro 文件。

我犯了一个愚蠢的错误。
我错过了一条 proguard 规则。这是奥托巴士的。
-keepattributes *Annotation*
-keepclassmembers class ** {
@com.squareup.otto.Subscribe public *;
@com.squareup.otto.Produce public *;
}
我只搜索了github。没有关于 proguard 的部分。我在 Square 的博客上找到的。
如果您的代码似乎受到 proguard 的影响，请检查两次并进行更多搜索！
我在 gradle.properties 中添加了以下行，之后工作顺利。
android.enableR8 = false
对我有用的解决方案是， 只需在开发者设置中禁用和启用调试选项按钮即可。
我有一个 API，在从启动屏幕导航到其他屏幕之前，其数据是必要的先决条件。这个 API 端点类似于
https://fakesite.com/pseudo-api//https://fakesite.com/pseudo-api/https://fakesite.com/pseudo-api禁用 R8 是一个糟糕的解决方案，它会阻止应用程序代码优化、代码缩减和混淆
要解决这个问题，你必须添加 ProGuard 规则来保留一些类
