Hi @DenBond7, we received feedback from a FlowCrypt Android user regarding the error in version 1.6.3 after the recent release.

Occurred in FlowCrypt android 1.6.3
User email says:

Hello Mart

thx f your fast reply before easter

Me: Samsung/Android

Your App, incidents message
"
Attempt to invoke
interface method „boolean
java.util.List.contains(java.lang.Object)
on a null object reference
"

This is interesting as it occures in all "folders" and especially the Inbox, but
not in Unread?!? (I lately discovered this, the fresh email disappeared from Unread after opening it a and returns in your >App if I mark as unread via webbrowser handling (this is obvious, but nevertheless what-the)

Got this incident for many days and stayed after an update with the same error message in your app.

Best

I'm a bit confused if this [1.6.3](#3000) version that is currently rolling out is partially affected by this, or if this particular PR is not included, or if it's possible that this issue has reoccurred.

Hello @martgil

I'm a bit confused if this #3000 version that is currently rolling out is partially affected by this, or if this particular PR is not included, or if it's possible that this issue has reoccurred.

I'm a bit confused too. This issue was fixed in 1.6.3. But we've received error logs where I see an interesting stack trace. NullPointerException occurred in a place where it's impossible based on the Kotlin language.

Line 93 in 149541e

return labelIds?.contains(GmailApiHelper.LABEL_TRASH) == true

Maybe it's a compilation issue.

Also, I've found similar error reports. I will fix it soon.

Thanks @DenBond7 for looking into this.
