Transfer from device fails when apps with the same title were selected

[anyc]

Hello,

I have a rather old table with Android 7 for the kids and due to the upcoming Amazon Appstore shutdown I wanted to backup some apps (maybe some of them work without the store). I noticed that the download of the apps starts but it always just stops after the same amount of bytes. I "bisected" the issue and noticed it always fails when two games with the same name shall be transferred. If I only transfer one of them, it works. These are games of a series so they actually differ at the end of the name. Also the Android launcher shows the same name for them but different icons.

I was able to backup my apps but I guess a fix might be helpful for others.

Thank you!

Could you provide me with the name of the two games?

For example:

https://play.google.com/store/apps/details?id=se.filimundus.pettsonsinventions
https://play.google.com/store/apps/details?id=se.filimundus.pi2

These are both shown as "Erfindungen". Maybe it would help to append the app id to the name?

I don't extinguish between apps with their app labels.
When you add an app or a file in the app, it assigns each app and file with a unique uuid.

So initially I think the issue might be caused by something else.

Ok, the other two were these:

https://play.google.com/store/apps/details?id=com.headupgames.bridgeconstructor
https://play.google.com/store/apps/details?id=com.headupgames.bridgeconstructormedieval

(but from the Amazon Appstore)

I forgot to say, I also enabled the debug mode but did not get any error message.

But as the APKs in the ZIP file use the app label as filename, I guessed that it causes an issue if two files with the same name are added to a ZIP archive.
