I currently encounter some APK download and install issue.
So I make many copies of my project for any further modification. (xxx-1, xxx-2,…)
But I can’t generate any workable APK file after version 4.
So I go back to first workable version project(xxx-1), and the download the APK again,
the new APK can’t be installed on my Android phone anymore.
The old APK file still can be installed.
I check file size of two APK file is exactly the same.
Did any one encounter this issue before?
