I wanted to create google like widget. I tried zorglub76 solution, but I wasn't able to get voice the result...

I solved it by creating a dummy transparrent activity that handles the voice recognition end-to-end.

It work as follows: Widget->VoiceRecognitionStarterActivity->RecognizerIntent->VoiceRecognitionStarterActivity.onActivityResult.

My widget class:

public class MyWidgetProvider extends AppWidgetProvider {

@Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager,int[] appWidgetIds) {

    // Get all ids
    ComponentName thisWidget = new ComponentName(context, MyWidgetProvider.class);
    int[] allWidgetIds = appWidgetManager.getAppWidgetIds(thisWidget);
    for (int widgetId : allWidgetIds) {
        RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.widget_layout);

        Intent activityIntent = new Intent(context, VoiceRecognitionStarterActivity.class);
        PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, activityIntent, 0);
        remoteViews.setOnClickPendingIntent(R.id.mic_image, pendingIntent);

        activityIntent = new Intent(Intent.ACTION_VIEW, Uri.parse(context.getString(R.string.search_url)));
        pendingIntent = PendingIntent.getActivity(context, 0, activityIntent, 0);
        remoteViews.setOnClickPendingIntent(R.id.search_box_image, pendingIntent);

        appWidgetManager.updateAppWidget(widgetId, remoteViews);

    }
    }
}

My transparrent activity:

   public class VoiceRecognitionStarterActivity extends Activity
{
    private static final String TAG = "VoiceRecognitionStarterActivity";
    private int SPEECH_REQUEST_CODE = 1;

    @Override

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    sendRecognizeIntent();
}

private void sendRecognizeIntent()
{
    Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
    intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
    intent.putExtra(RecognizerIntent.EXTRA_PROMPT, "Speak to search");
    intent.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS, 10);
    startActivityForResult(intent, SPEECH_REQUEST_CODE);
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
    if (requestCode == SPEECH_REQUEST_CODE)
    {
        if (resultCode == RESULT_OK) {
            Log.d(TAG, "result ok");
            Intent searchIntent = new Intent(Intent.ACTION_VIEW, Uri.parse(getString(R.string.search_url)));
            startActivity(searchIntent);
            finish();   
         } else {
            Log.d(TAG, "result NOT ok");
            finish();
        }

    }

    super.onActivityResult(requestCode, resultCode, data);
    }

}
