Push notifications from the PushNotification tool are never delivered to the Android device, even though all settings appear correct.

Confirmed working:

Remote Control shows "Verbunden" (Connected) in green in the Android app
Claude Code CLI reports "Terminal notification sent. Mobile push requested."
Android notification permissions fully enabled (Allow ✓, Sound & Vibration ✓, Lock screen ✓, Banner ✓)
Battery optimization for Claude set to "Unrestricted" (tested both before and after this change)
App was running in the background (not force-closed) during all tests
User inactivity confirmed >60s before each push attempt (CLI threshold is 60s)

Description

Push notifications from the PushNotification tool are never delivered to the Android device, even though all settings appear correct.

Confirmed working:

Remote Control shows "Verbunden" (Connected) in green in the Android app
Claude Code CLI reports "Terminal notification sent. Mobile push requested."
Android notification permissions fully enabled (Allow ✓, Sound & Vibration ✓, Lock screen ✓, Banner ✓)
Battery optimization for Claude set to "Unrestricted" (tested both before and after this change)
App was running in the background (not force-closed) during all tests
User inactivity confirmed >60s before each push attempt (CLI threshold is 60s)

Steps to Reproduce

Open Claude Android app — session shows "Connected" (green) under Remote Control
Send app to background via Home button (not force-closed)
Run a long task in Claude Code CLI on desktop that triggers PushNotification
Wait >60s of user inactivity — CLI confirms "Terminal notification sent. Mobile push requested."
No notification appears on the Android device

Expected Behavior

A push notification banner appears on the Android device when the CLI reports "Mobile push requested."

Actual Behavior

No notification is delivered. The CLI confirms the push was requested but nothing arrives on the phone. The session shows as Connected in the Android app throughout.

Additional Notes

All other apps (Chrome, WhatsApp, Email) deliver notifications normally on this device
Tested 6+ times across one session with varying conditions
Battery optimization set to "Unrestricted" after initial tests — no improvement
Samsung S23, standard Android (no custom ROM, no special notification blockers)
The 60s inactivity threshold was consistently exceeded before each push attempt

extent analysis

TL;DR

Check the Firebase Cloud Messaging (FCM) or Google Cloud Messaging (GCM) configuration and ensure the Claude Android app is correctly registered to receive push notifications.

Guidance

Verify that the Claude Android app has the correct package name and API key configured for FCM or GCM.
Check the AndroidManifest.xml file for the necessary permissions and services related to push notifications.
Ensure that the Claude Code CLI is sending the push notification to the correct FCM or GCM registration token associated with the Android device.
Review the device logs for any errors related to push notification delivery.

Example

No code snippet is provided as the issue does not contain sufficient information about the implementation.

Notes

The issue may be related to the configuration of the push notification service or the registration of the Android app. Without more information about the implementation, it is difficult to provide a more specific solution.

Recommendation

Apply workaround: Verify the FCM or GCM configuration and registration of the Android app to ensure correct push notification delivery. This is recommended as the issue seems to be related to the configuration rather than a code-level problem.
