• Is the issue reproducible with (the latest) TWRP recovery? (other recoveries are only best-effort)~

~If receiving force closures after Open GApps installation:

• The issue is NOT an error within one of the bundled Google applications itself (verify by e.g. installing the application from the Play Store instead)

• No non-AOSP hacks like privacy guards' permission restrictions etcetera are applied~

Issue description:
I installed the OpenGapps nano package onto my stock ROM (clean AOSP, Android One second gen MTK variant) to update the core apps like Play Store, Google etc. When I booted back into AOSP, my Google Now Launcher was gone, so was Keep and Gmail.

Reproduction Steps:

1. Install OpenGapps nano package over a clean AOSP factory ROM
2. Boot back to find apps mentioned above missing.

Expected behavior:

Only the apps the Installer is adding should have been removed

Observed behavior:

But it did a general cleanup from what I can deduce.

Where you apps installed on /system? Because Open GApps currently doesn't (and can't) differentiate between wanting to remove an app, or not wanting to update an app. So it removes any app on /system that is part of the Open GApps installation options (including the bigger packages).

[msfjarvis]

I'm assuming the "Where you" is a typo that means "Were your". Yes, they were all on /system, and OpenGapps did kill off all Google Apps it found (Thanks for that, I was being a bit lazy to remove the extra Play Movies and other bloat :p )

[msfjarvis]

But I kinda like and use Keep and Gmail, so it's a :( for removing them too...

[msfjarvis]

@opengapps/developers is this something we can expect to be ever added into the installer?

[mfonville]

@MSF-Jarvis indeed I meant 'were'.
I think we will probably change this yes. The current behaviour is according to how PA GApps behaved, but it does not match people's expectations.
I guess we will do this when we are going to revise the current package sets, names and the config.

I will update the description accordingly.

Thanks @mfonville. We should keep this open,no?

[mfonville]

@MSF-Jarvis we keep this open as tracking bug

[msfjarvis]

@mfonville any headstart with this?

[mfonville]

@MSF-Jarvis not yet, some recent health issues have severely slowed down my pace of development :(

[msfjarvis]

Looks like this is fixed :)
