I'm developing a speech recognition android plugin for a Phonegap application. I am actually new to Phonegap. Below is the important sections from my Java code. From this code, I need to call the Javascript function test.
public class CoolPlugin extends CordovaPlugin {
public static final String TAG = "Cool Plugin";
private SpeechRecognizer speech = null;
private Intent recognizerIntent;
private String LOG_TAG = "VoiceRecognitionActivity";
private List<String> previousInterim;
private List<String>adapterList = new ArrayList<String>();
private static final String INITIALIZE = "init";
private static final String PLAY = "play";
private static final String STOP = "stop";
private AudioManager mAudioManager;
private int mStreamVolume = 0;
private Context context;
public boolean execute(final String action, JSONArray args, final CallbackContext callbackContext) throws JSONException
{
if(PLAY.equals(action))
{
cordova.getActivity().runOnUiThread(new Runnable() {
public void run() {
play(callbackContext);
}
});
}
return true;
}
public void play(CallbackContext callbackContext)
{
//Start listening
speech.stopListening();
speech.cancel();
speech.destroy();
createRecog();
speech.startListening(recognizerIntent);
//adapter.clear();
}
private class RecognitionListenerClass implements RecognitionListener
{
CallbackContext callbackContext;
void onStartOfSpeechTimeout(CallbackContext callbackContext)
{
this.callbackContext = callbackContext;
};
@Override
public void onPartialResults(Bundle arg0) {
Log.i(LOG_TAG, "onPartialResults");
final ArrayList<String> matches = arg0.getStringArrayList(SpeechRecognizer.RESULTS_RECOGNITION);
final float[] scores = arg0.getFloatArray(SpeechRecognizer.CONFIDENCE_SCORES);
receiveWhatWasHeard(matches, scores);
}
}
private void receiveWhatWasHeard(ArrayList<String> matches, float[] scores)
{
//CALL THE JAVASCRIPT FUNCTION!!
}
}
From the method receiveWhatWasHeard, I need to call a javascript function. Since this is a speech application, please note that this call be will be called everytime it hear something.
Below is a part of my JavaScript code..
var exec = require('cordova/exec');
function CoolPlugin() {
console.log("CoolPlugin.js: is created");
}
CoolPlugin.prototype.startRecognition = function(){
console.log("CoolPlugin.js: showToast");
exec(function(result){
/*alert("OK" + reply);*/
},
function(result){
/*alert("Error" + reply);*/
},"CoolPlugin","play",[]);
}
CoolPlugin.prototype.test = function(){
//Do something and return information
}
var coolPlugin = new CoolPlugin();
module.exports = coolPlugin;
No need to say that most of the phonegap tutorials are totally outdated and I am struggling for this for the past few days. Any idea about how to implement this Java to Javascript callback?
