Android: How to prevent resumeRecording if phone call in progress?

[GautierT]

Currently, when trying to resume recording during a phone call on Android, the recording appears to work but produces empty audio during the call portion. This creates a misleading experience for users who might think the recording is working properly.

Expected behavior:

• Recording should not resume if there's an ongoing phone call
• User should be notified that recording cannot be resumed during calls

Current behavior:

• Recording can be resumed during calls
• Recording produces empty/silent audio during call portion
• No warning is shown to users

Possible solutions:

1. Check phone call state before allowing resumeRecording
2. Show an error message if user attempts to resume during a call
3. Disable resume button/functionality when call is detected
4. Expose a isPhoneCallInProgress to let the developper decide what to do ?

Questions:

• Is this behavior due to geographic/legal restrictions? (fix: improve audio recording interruption handling and consistency #98 (comment))
• What's the best way to detect ongoing phone calls on Android?

Additional context:
This issue aims to improve user experience by preventing silent recordings when calls are in progress.
