如何发布一个使用Hive存储数据的App ?

Question

我在Play Store上推出了App催钱功能。问题是使用Hive存储数据的部分不能工作。但是当我在发布模式下运行它时，我得到一个错误。我使用Android Studio和Language Flutter。我在google Play主机上发布了这款应用。

这是我得到的错误

adb: failed to install C:UsersNiklasStudioProjectsmoneyreminderbuildappoutputs flap -apkapp.apk: Failure [INSTALL_FAILED_UPDATE_INCOMPATIBLE: Package com.muellerniklas.moneyreminder签名不匹配先前安装的版本;忽略!)

这是我到应用程序的链接

我的项目有更多的文件hive和类名为data。如果你需要的话，我可以寄给你。

Answer 1

不可能。Hive使用的应用程序到商店没有任何特殊要求。我很确定你在程序上做错了什么，但你认为那是因为你发表错了。

解决方案:使用flutter run -— release运行app。并检查是否一切正常。
