應用程序連續崩潰java.lang.ClassNotFoundException

Question

Senerio就是這樣，我的帶有Version.1 的應用程序存在於priv-app文件夾中，並且工作正常，現在我要用新的Version.2更新它。 應用程序從LauncherActivity.java啟動 ，運行時沒有崩潰。 NullPointerException會在程序的某個位置發生崩潰，然后退出應用程序，當我嘗試打開它時，它開始崩潰。 我正在使用外部庫，並檢查了Order and Export PackageName中的所有庫均為com.example這是LOG-

Answer 1

我認為應該是com.example.AppApplication.LauncherActivity

而不是清單中的com.example.LauncherActivity 。
