The Crash happens in onPause in SearchSupportFragment

@Override
    public void onPause() {
        releaseRecognizer();
        mIsPaused = true;
        super.onPause();
    }

particularly in releaseRecognizer();

Why's this happening?
When onResume is called the speechRecognizer is initialized but there's never a check whether the SpeechRecognizer is available, meaning

https://developer.android.com/reference/android/speech/SpeechRecognizer#isRecognitionAvailable(android.content.Context)

Inside the onResume function

 @Override
    public void onResume() {
        super.onResume();
        mIsPaused = false;
        if (mSpeechRecognitionCallback == null && null == mSpeechRecognizer) {
            mSpeechRecognizer = SpeechRecognizer.createSpeechRecognizer(
                    getContext());
            mSearchBar.setSpeechRecognizer(mSpeechRecognizer);
        }
        if (mPendingStartRecognitionWhenPaused) {
            mPendingStartRecognitionWhenPaused = false;
            mSearchBar.startRecognition();
        } else {
            // Ensure search bar state consistency when using external recognizer
            mSearchBar.stopRecognition();
        }
    }

There should be a check whether

if(SpeechRecognizer.isRecognitionAvailable(requireContext())
{
initializeSpeechRecognizer(); // copy the function body in onResume
}

Where does this break?
Especially on Amazon TV devices since they lack this speech recognizer.
