我编写了一个androidApp Widget，它工作正常。一段时间后，我不得不更改它的包名，但它运行良好。我已经有了getPackageName，它会在日志中打印正确的包名称，但有时在我升级应用程序（或者只是在设备上运行它AndroidStudio）之后，小部件就会消失。后来它在另一次升级后又回来了。这是我的日志：06-20 14:59:31.208 23516-23516/？E/InstalledAppDetails：检索包时出现异常：ir.yasin.dordane.rozshomar_widget

android.content.pm.PackageManager$NameNotFoundException: ir.yasin.dordane.rozshomar_widget
