 No Activity found to handle Intent { act=android.speech.action.RECOGNIZE_SPEECH (has extras) }

What can I do?

import android.os.Bundle;
import android.speech.RecognizerIntent;
import android.view.Menu;
import android.view.View;
import android.widget.ImageButton;
import android.widget.TextView;
import android.widget.Toast;

public class MainActivity extends Activity {

    protected static final int RESULT_SPEECH = 1;

    private ImageButton btnSpeak;
    private TextView txtText;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        txtText = (TextView) findViewById(R.id.txtText);

        btnSpeak = (ImageButton) findViewById(R.id.btnSpeak);

        btnSpeak.setOnClickListener(new View.OnClickListener() {

                intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, "en-US");

                try {

                    txtText.setText("");

                    Toast t = Toast.makeText(getApplicationContext(),
                            "Ops! Your device doesn't support Speech to Text",
                            Toast.LENGTH_SHORT);
                    t.show();
                }
            }
        });

    }

    @Override

    @Override

                ArrayList<String> text = data
                        .getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);

                txtText.setText(text.get(0));
            }
            break;

You need to install onto your emulator an app that contains an Activity that handles the RECOGNIZE_SPEECH-intent. You might be able to find Google's VoiceSearch.apk on the web.

Answer 3

There are certain things you can't test using an emulator. Speech to text is on of them.

I'm not sure about this, but you can't use this android feature with the emulator.

No matter what, you should handle this exception with a try/ catch an give some feedback to the user.

You can check if there is that Activity in current device running your app doing something like:

        PackageManager pm = context.getPackageManager();
        List<ResolveInfo> infoList = pm.queryIntentActivities(new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH), 0);
        if (infoList.size() == 0) {
             /** Show some feedback to user if there is the activity. Something like "Your device is not abl to run this feature..."*/
        }else{
             /**Your current code goes here.*/
        }

Let me know if it helps.

Answer 4

You need to install com.google.android.voicesearch application on target device which has no voice recognition activity like:

Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=com.google.android.voicesearch"));
startActivity(browserIntent);

if you try to install Google's Search app - it won't help since it doesn't contain the VR engine inside and thus it will try to do the same - install com.google.android.voicesearch app but it could fail due to a bug in package name (pname:com.google.android.voicesearch instead of just pure package name). However com.google.android.voicesearch installation might be impossible due to "Not available in your country".

You might need a virtual SD Card. You can refer here
