bug: Push Fetch mode fails on Android 16 – Notifications show "Unknown"

[sleeplessnight2]

Describe the Bug

On Android 16, the Rocket.Chat app shows push notifications in fetch mode as "Unknown". Users on older Android versions or other devices do not experience this issue.

Steps to Reproduce

1. Install the Rocket.Chat app (latest version from Google Play)
2. Go to Settings → Push → Enable “Fetch full message content on push receive”
3. Send a Rocket.Chat push → notification shows only "Unknown"
4. Disable fetch mode → name + message content appear correctly

Expected Behavior

Push notification should display name + message content, fetch mode works as intended

Actual Behavior

Push shows only "Unknown", fetch mode is blocked on Android 16

Rocket.Chat Server Version

7.12.1

Rocket.Chat App Version

4.66.1.107670

Device Name

Pixel 7 Pro

OS Version

Android 16 (Stock)

Additional Context

ADB logcat for the notification:

NotificationRecord: pkg=chat.rocket.android user=UserHandle{0} id=<redacted> 
Notification(channel=rocketchatrn_channel_01, importance=4, visibility=PRIVATE)
StatusBarNotification: pkg=chat.rocket.android user=UserHandle{0} id=<redacted>
NotificationChannel: mId='rocketchatrn_channel_01', mName='All', mImportance=4

Manual fetch broadcast:

adb shell am broadcast -a chat.rocket.android.intent.action.FETCH_PUSH_CONTENT
Broadcasting: Intent { act=chat.rocket.android.intent.action.FETCH_PUSH_CONTENT }
Broadcast completed: result=0

Intent is received, but fetch does not execute

Thanks for reporting this! Right now, the app officially supports up to Android 15. Because of that some things may not work correctly on Android 16 yet.

We are currently working on proper Android 16 support, including the new 16 KB memory changes. I will try to prepare a fix for this issue but it won’t be ready this month.

I will keep you updated as things progress and let you know as soon as a fix is available.
