问题描述

我的应用程序在模拟器中运行良好，甚至在 android studio 安装的用于调试目的的真实设备中运行良好，但如果使用 apk 文件手动安装，它会崩溃.

My Application is running fine in Emulators and even in real devices installed by android studio for debugging purpose, but it is crashing if installed manually using apk file.

如果需要，我准备粘贴任何其他代码，例如 Activity.

I am ready to paste any other codes, like Activity if required.
