bug: [Android] Push notifications cause app to crash

[sleeplessnight2]

Describe the Bug

When the app receives a push notification, it crashes completely.

Steps to Reproduce

Simply send a test push message to the client. This even works in the administration via the "Send me a test push message" button.

Expected Behavior

No response

Actual Behavior

No response

Rocket.Chat Server Version

7.10.0

Rocket.Chat App Version

4.64.0.107286

Device Name

Google Pixel 7 Pro

OS Version

latest

Additional Context

No response

[sleeplessnight2]

It works with the experimental version 4.64.0.107162. It no longer works with 4.65.0.107333.

Can you provide more context ?

[sleeplessnight2]

I don't know what exactly is missing.
The app crashes as soon as it's running in the background and you send a message to this client. See screenshot.

Sometimes this happens even without a notification from Android. In any case, push notifications are no longer arriving. However, it works with older versions (as mentioned above).

And it's not just my Android that's affected - everyone I know who has updated the app to the latest release is affected too.

Hi. I'm having the same problem on different Android devices.
Server: 7.7.4
App: 4.63.0 whitelabel (single-server)
Device: Samsung S24+,Samsung S23 Ultra and more another (Oppo, Xiaomi etc)
I have a whitelabel Android app. In Firebase, I see this error:

Fatal Exception: java.lang.NullPointerException: Attempt to invoke virtual method 'int java.lang.String.indexOf(java.lang.String)' on a null object reference

Push works perfectly with the official app 4.63.0.96963.
I don't know if your error has a different cause.

As I said, the app 4.64 and higher is currently unusable. The app crashes as soon as a push notification comes in while I'm writing.
In the experimental app, I can even kill myself directly via the admin panel when logged in as an admin by clicking "Send me a test push notification."

[sleeplessnight2]

I took the trouble to extract a crash log.
Hopefully this will help find a quick solution.

[diegolmello]

@sleeplessnight2 @arpsyapathy I worked on a fix #6667

I'm going to trigger a build and need you to test that version.
Can you do that?
Sending the build here asap.

@diegolmello Cool! I can only do it on Monday

[sleeplessnight2]

@diegolmello
It works with the experimental version 4.65.0.107352 linked there.

Hopefully, this can be released soon as a hotfix for the stable version...

[arpsyapathy]

@diegolmello
Have you figured out how to reproduce this issue manually?
I don't know how to reproduce it manually for testing. The app itself crashes periodically for users.

[diegolmello]

@arpsyapathy install it and use it for a few days #6667 (comment)

Positive feedback from @sleeplessnight2 already 🙏🏼

The idea is to have a release later this week, so I'll wait two days for your feedback here, @arpsyapathy. After that I'm going to merge the PR and start the release process.

Hello! I've pushed the changes from the commit to my whitelabel app.
We'll test it on a few devices today and tomorrow, and I'll let you know the results the day after. Thanks for the quick fixes!
