MainActivity has leaked ServiceConnection android.speech.SpeechRecognizer$Connection@414ee400 that was originally bound here

In my app I recognize the user saying "exit" or "close" and the app should close. With this code

SpeechRecognizer sr;
Map<String, Integer> dictionary;
private static final int EXIT = 1;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    populateDictionary();
    SpeechRecognizer sr = SpeechRecognizer.createSpeechRecognizer(this);
    sr.setRecognitionListener(this);
    Intent voiceIntent = RecognizerIntent.getVoiceDetailsIntent(getApplicationContext());
    sr.startListening(voiceIntent);
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}

private void populateDictionary() {
    dictionary = new HashMap<String, Integer>();
    dictionary.put("exit", EXIT);
    dictionary.put("close", EXIT);
}

@Override
public void onResults(Bundle results) {
    ArrayList<String> strList = results.getStringArrayList(SpeechRecognizer.RESULTS_RECOGNITION);
    for (int i = 0; i < strList.size();i++ ) {
        String sentence = strList.get(i).toLowerCase(Locale.getDefault());
        Integer operation = dictionary.get(sentence);
        if(operation != null){
            switch(operation){
                case EXIT:{
                    this.finish();
                };break;
            }
        }
    }
}

I get this runtime error, after the speech recognition.

If I try to destroy the SpeechRecognizer I get another runtime error because sr is null.

@Override
public void onDestroy(){
    sr.destroy();
    super.onDestroy();
}

What should I do?

The problem was the most trivial ever: I declared the SpeechRecognizer two times, one for the class and another inside the onCreate() method. The variable was initialized only in the function scope, so outside the function sr was always null.

So how you solve the ServiceConnectionLeaked error? – Vesuvius 13/4, 2018 at 1:20

I used singleton class to solve it. Don't initialize it with different contexts, instead use singleton :) – Misestimate 30/6, 2018 at 9:28

I think problem may be at line:

sr.destroy();

If sr be null, you get NullPointerException, and

super.onDestroy();

Dont has been called. Try do next:

if(sr!=null)
{
    sr.destroy();
}

or:

try{
        sr.destroy();
} 
 catch (Exception e)
{
 Log.e(TAG,"Exception:"+e.toString());
}

In fact sr.destroy(); throws java.lang.NullPointerException: sr is null so I can't destroy it, but seems that simply calling this.finish() leaves open the speech recognition service. I have no idea how to close it correctly at this point. – Kalle 12/11, 2013 at 14:14

if you in: switch(operation) calling this.finish, why before this.finish you dont call sr.destroy? – Comprador 12/11, 2013 at 14:20

if I call sr.destroy() before this.finish() I get a java.lang.NullPointerException – Kalle 12/11, 2013 at 14:24

Added log for both cases – Kalle 12/11, 2013 at 14:41

try this: sr.cancel; this.finish(); in block switch – Comprador 12/11, 2013 at 14:46

sr is null, so I always get a NullPointerException – Kalle 12/11, 2013 at 14:51

My solution for Dialog:

public void dismiss(){
    speech.stopListening();
    try{
        speech.destroy();
    }
    catch (Exception e)
    {
        Log.e(TAG,"Exception:" + e.toString());
    }
    super.dismiss();
}

initialize your text to speech using application context, not activity context.

val textToSpeech = TextToSpeech(applicationContext)
