Question

I am using google speech recognizer for integrating voice services in Android but while pressing on mic button this annoying toast message is showing. Please suggest me a way to

You can make a custom speech recogniser which will give you more control over the UI. MainActivity opens a new DialogFragment which implements RecognitionListener .

public class MainActivity extends AppCompatActivity implements VoiceRecognizerInterface {
    Button button ;
    TextView textView;
    String string;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        button = findViewById(R.id.button);
        textView = findViewById(R.id.textView);
        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                FragmentManager fragmentManager = getSupportFragmentManager();
                if (fragmentManager != null && fragmentManager.findFragmentByTag("dialogVoiceRecognizer") == null && !isFinishing()) {
                    VoiceRecognizerDialogFragment languageDialogFragment = new VoiceRecognizerDialogFragment(MainActivity.this,MainActivity.this);
                    languageDialogFragment.show(fragmentManager, "dialogVoiceRecognizer");
                }
            }
        });
    }

    @Override
    public void spokenText(String spokenText) {
        textView.setText(spokenText);
    }
}

An interface to signal the main activity after stt.

public interface VoiceRecognizerInterface {
    void spokenText(String spokenText);
}

The custom SpeechToText Dialog.

public class VoiceRecognizerDialogFragment extends DialogFragment implements RecognitionListener{

    ImageView micImage;
    TextView stateTV;
    TextView displayTV;

    private SpeechRecognizer mSpeechRecognizer;
    private Intent mSpeechRecognizerIntent;
    private Context context;
    VoiceRecognizerInterface signal;

    @SuppressLint("ValidFragment")
    public VoiceRecognizerDialogFragment(Context context, VoiceRecognizerInterface signal) {
        this.context = context;
        this.signal = signal;
    }

    public VoiceRecognizerDialogFragment(){

    }

    @Nullable
    @Override
    public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.voice_recognizer_custom_layout ,container, false );

        //Mic tap to listen again
        micImage = view.findViewById(R.id.micImageView);
        //Displays Listening.. when recognizer is listening
        stateTV = view.findViewById(R.id.stateTV);
        //Displays message if error
        displayTV = view.findViewById(R.id.displayTV);

        mSpeechRecognizer = SpeechRecognizer.createSpeechRecognizer(context);
        mSpeechRecognizerIntent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
        mSpeechRecognizerIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
                RecognizerIntent.LANGUAGE_MODEL_WEB_SEARCH);
        //Customize language by passing language code
        mSpeechRecognizerIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE,"en");
        //To receive partial results on the callback
        mSpeechRecognizerIntent.putExtra(RecognizerIntent.EXTRA_PARTIAL_RESULTS,true);
        mSpeechRecognizerIntent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE,
                context.getPackageName());
        mSpeechRecognizer.setRecognitionListener(this);
        mSpeechRecognizer.startListening(mSpeechRecognizerIntent);
        micImage.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                startListening();
            }
        });
        return view;

    public void startListening(){
