【中文标题】将我的应用程序发布到 google playstore 后，我的应用程序无法获取 firestore 数据以回收分页视图【英文标题】：After Publishing my apps to google playstore, my Apps cannot fetch firestore data to recycle pagination view 【发布时间】：2021-06-29 10:12:18 【问题描述】：在发布到 Play 商店之前测试我的应用程序时。我的应用能够从 firestore 获取数据以回收视图。
在第二张图片中，在上传文件之前，应用程序可以从 Firestore 读取数据，但无法将其提取到回收视图中 这是问题的代码：

// @Override

所以这是我用于该活动文件的代码，但在其他 2 个活动中也出现了同样的问题。 所以无法抓住问题 这也是我在 Playstore 中的应用的链接

【问题讨论】：
ibb.co/…这是从playstore上传安装后的图片 您通过Launch Checklist 工作了吗？默认情况下，FirestoreRecyclerAdapter 会记录其查询的任何错误，因此请查看您应用的日志以获取更多信息。
ibb.co/QQdTp5t ibb.co/5kxXbkB 你在说这个吗？
您是否尝试记录错误？也许出了点问题而你不知道。
它崩溃了
【参考方案1】：
这是 pro gruad 中的错误....来自 google 的收缩功能... 禁用它
我没有在网上找到它.....自己排序。
//minifyEnabled true
//shrinkResources true
//proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
【讨论】：
【参考方案2】：这是因为 progaurds minify 在您编译程序时会更改类的名称。
您可以更改构建 gradle 以使 minifyEnabled 为 false，或者您可以在您使用的模型类之前使用 @Keep 来保留它们的 Firestore 命名约定。
