contains() method not working as expected

I am building a voice assistant for android, here this method retrieves contact names one by one and compares it to to SpeechToText input.

I am successfully getting the contact names, but when I am comparing it with my input text, nothing is happening.

Here is the code

private void callFromContact(String text_received, int index){

    Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,null,null, null);
    while (phones.moveToNext())
    {
        String name=phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
        if(text_received.toLowerCase().contains(name)){
            String phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
            contactNames.add(name);
            contactNumbers.add(phoneNumber);
        }
    }

Here for example I sending “call karan” as input, while debugging the name “Karan” comes up as the value of name variable, but when comparing it in if-statement, nothing happens, I mean the next statement is not executed, what might be the problem, help would be appreciated.

Answer

You need to convert the name variable to lowercase too, because String.contains() method is case sensitive, so call karan doesn’t contain Karan.
