I tried all the solution answered on this question, none of those worked for me. But after some search I found this post. Using the RxJava to make the debounce worked well for me. Here goes my final solution:

Add RxJava dependencies in the Gradle file:

compile 'io.reactivex:rxandroid:1.0.1'
compile 'io.reactivex:rxjava:1.0.14'
compile 'com.artemzin.rxjava:proguard-rules:1.0.14.2'

Implement your subject:

PublishSubject yourSubject = PublishSubject.create();
    yourSubject .debounce(100, TimeUnit.MILLISECONDS)
            .onBackpressureLatest()
            .subscribe(s -> {
                //Implements anything you want
            });

Use your subject in your TextWatcher:

TextWatcher myTextWatcher = new TextWatcher() {
    @Override
    public void beforeTextChanged(CharSequence s, int start, int count, int after) {
    }

    @Override
    public void onTextChanged(CharSequence s, int start, int before, int count) {
        yourSubject.onNext(s.toString()); //apply here your subject
    }

    @Override
    public void afterTextChanged(Editable s) {
    }
};

Add the TextWatcher in the EditText listener:

my_edit_text.addTextChangedListener(myTextWatcher);
