Android应用在某些设备上无法使用(Android app won't work in some of the devices)

Android应用在某些设备上无法使用(Android app won't work in some of the devices)

我创建了一个显示Firebase孩子的应用程序。 它在我的手机（nexus 6）中工作，并在另一个（一加3）中工作，但是当我将其安装在其他设备（如红米注释3）中时，应用程序部队关闭，我不知道为什么会发生这种情况。

这里是卡片视图布局，里面没有任何按钮，因为我昨天已经删除了按钮，并用ImageViews进行了更新

I created a app which displays firebase childs. It's working in my phone (nexus 6) and works in another (one plus 3), but when I installed it in other devices like a redmi note 3, the app force closes, I am not sure why this is happening.

最满意答案

有时候，在IDE中会出现问题，他们会让分配的id变得乱七八糟，并且项目需要需要重建，清理甚至使缓存无效并在某些情况下重新启动。 同样，在这种情况下，代码看起来很好，干净，重新构建，然后再次在小米上运行您的应用程序。

Sometimes, issue arises in IDEs that they make mess of assigned ids and project needs need to be rebuilt, clean and even invalidate cache and restart in some cases. As in this case, as well, code looks ok, clean, re-build then run your app on Xiaomi again.
