android - Application is not installed error, when launched from home screen shortcut

Question

FYI: I have gone through these links already 'App not Installed' Error on Android

Application not installed when i try to autoupdate

My question is little different.

• I released app with default/main activity as XActiivity.java in version 1.0
• I released update with changing default/main activity as YActivity.java
• I find that app opens fine from application meanu, but when I try to launch from home screen shortcut, it throws an error saying "Application is not installed"

I know that its due to shortcut referencing to old XActivity.java, by removing would solve this issue, but if I release app to thousands as an update who already have this app would get annoyed at the first instance of this error message. I would loose on good reviews I got

Please check if you have the property android:exported="false" on an activity that should have been a "android.intent.category.LAUNCHER". This disables the specific activity from being launched on the launcher.
