[Cabanon]

Affected app
Name: Green-Got
Package id: com.greengot

Describe the bug
When opening the app, it freezes just after trying to connect with my account

To Reproduce

1. Open the app
2. Click on Connect
3. Enter email
4. Enter the code received by email

Expected behavior
The app should open normally

System
Android Version: 12
Custom ROM: /e/OS 1.16-s

microG
microG Core version: 0.2.29.233013-2 (8c25b3f)
microG Self-Check results: All ticked

Additional context
When logging with ADB, I noticed 2 lines happening right when the application freezes:

11-10 11:22:11.259 D/GmsTapAndPay( 3539): onBind: Intent { act=com.google.android.gms.tapandpay.service.BIND pkg=com.google.android.gms }

11-10 11:54:37.308 W/GmsTapAndPay( 3539): Unknown method 74 in com.google.android.gms.tapandpay.internal.ITapAndPayService, skipping

Also I tried with an emulator with GAPPS installed and the ADB log indicates the following and the app launches correctly

So it looks like the app works correctly even without Tap and Pay support, but doesn't work with microG for some reason

[MagicRB]

The reason for this is probably that the app checks for presence of Google services, if it doesn't see them it bails and takes a different code path. With microG present it takes the default path and rightfully assumes com.google.android.gms.tapandpay.internal.ITapAndPayService is available and functional (which it isn't) and so it crashes. Resolving this is related to #361 but may only require a partial bandaid depending on the details of that service.

Actually fixing this is way beyond my skill set though, sadly.

[ale5000-git]

The reason is probably because he/she is using a very older version of microG.

[MagicRB]

I'm hitting the exact same missing service in google wallet and revolut, just now and im one version behind.

[ale5000-git]

I don't remember exactly but I think it was a recent change so if you don't get the version v0.3.2 of both microG Services and microG Companion probably you won't see improvements.

I am not sure what improvement you suppose to have. I encountered the same error Unknown method 74 in com.google.android.gms.tapandpay.internal.ITapAndPayService, skipping under MicroG 0.3.2.240913 when I try to enable "Google Pay" in BoursoBank app.

[ale5000-git]

There is some minimal support in the code but I guess it isn't complete enough to make app works.

[knocte]

How can we help here?

[ale5000-git]

Mainly two possibilities:

• Learn to code
• or wait it to be implemented by others

[knocte]

I'm a coder, just check my github profile. I'm asking about technical specifics because I've never worked on this project.

[ale5000-git]

I don't know too much about this specific issue, I only looked at the commits and there was changes about this issue.
I think it is @mar-v-in that know more about this.

[ale5000-git]

Usually to get more info about Google Play Services one need to:

• Find specs online (not always available)
• Or deduct specs by inputs/outputs
• Or sniff network traffic of Google Play Services
• Or reverse engineer Google Play Services

As far as I understand, right now, there are only dummies: 91e830b
