Android STT enters permanent true with error_speech_timeout and error_busy state requiring phone restart

[rgopani]

The application enters an infinite loop of Speech-to-Text (STT) resets and error prompts when a permanent error_speech_timeout or error_busy state occurs on Android devices.

Once this state occurs:
• ❌ Closing and reopening the app does not fix the issue
• ❌ Uninstalling and reinstalling the app does not fix the issue
• ❌ Clearing app data/cache does not fix the issue
• ✅ Only restarting the phone restores STT functionality

Application Functionality
• The bot asks questions based on responses received from an API.
• The user replies to each question (via voice STT).
• The user’s response is submitted to the backend using an API call.
• Based on the submitted response, the backend determines and returns the next question.
• This question–answer flow continues until the process is completed.
• The user can move the app between foreground and background during the conversation without breaking the flow.

Request
• Please clarify whether continuous STT is supported on Android
• Is there any way to fully reset the SpeechRecognizer service?
