java应用程序在测试设备上调试时工作正常,但在发布版apk中没有,它没有获得post。来自firebase的类变量

我的应用程序在活动中有帖子,帖子有一个图像和类似按钮,还有星星计数和共享按钮。当调试到测试设备时,一切正常,但在发布的版本中不正常。 在GoogleStore上发布应用程序后,所有变量都会显示在post下。类未被接收/显示(使用post.get的所有内容,例如post.getimage()未从firebase数据库获取值。另一方面,接收存储在post之外的值(例如,我有一个单独的starcount节点,我得到了childcount的值,它工作正常)。 我已经尝试了所有可能的解决方案,但没有任何效果: 使用SHA发布密钥(上载密钥)更新应用程序,然后生成已签名的apk(aab),所有三个SHA(调试、发布和应用程序签名密钥)都保存在我的firebase项目指纹下。 我还检查了firebase数据库规则。 我在帖子中更改了一些变量。从公共课到私人课

我直接在设备上下载了APK,而且它不工作。它在测试设备上运行良好。如果有人能提供帮助,我将不胜感激

    经过两天的搜索,我找到了问题的答案: 造成这个问题的是Proguard。创建签名的APK时,Proguard会清除所有未使用的代码或类。。就我的情况而言,这是一篇博文。Proguard错误地删除了类:

    解决方案:

    • 我把它放在柱子上。类和其他类,我希望确保Proguard不会在一个包(模型)下删除它们,您可以将它们放在不同的包下,但您需要在Proguard规则下列出所有这些类,如下所示:

    • 在5月份的android studio项目中,我打开了proguard rules。pro

    • 当Proguard创建签名的APK(或aab)时,我将下面的一行放在列表中,并防止类被删除

      -keepclassmembers class com.mydomain.app.models.** {*;} 
      

    在哪里。领域app是包的名称

    希望这能节省某人的时间
