Question

I am working on android app that receives a broadcast intent for incoming calls and incoming text messages.

It then is supposed to get the incoming number and perform a search on the users contacts using the incoming number.

This is more a less working, but I am having a slight problem. I have it working so that the number is searched in the contact list by, if it starts with + strips the first 3 characters and puts a 0 on the beginning, or just a does a search if it doesn’t contain the +. However, I have a slight problem, that if the user enters spaces in the number then the app doesn’t find the contact. For example, if I have a contact number saved as 07412xxxxxx and the incoming number comes in as 07412xxxxxx or +447412xxxxxx. However, if the contact number is saved as `07412 xxx xxxand the incoming number is07412xxxxxx“ then the number doesn’t get recognised so it doesn’t find the contacts name.

How can I perform the search to take all considerations of the number format. Below is the code I am currently using.

public String getContactNameFromNumber(String number)
    {

        if (number.startsWith("+"))
        {
            number = "0" + number.substring(3);
        }

        String contactName = null;
        ContentResolver contentResolver = context.getContentResolver();

        Uri uri = Data.CONTENT_URI;
        String[] projection = new String[] {PhoneLookup._ID, PhoneLookup.DISPLAY_NAME};
        String selection = ContactsContract.CommonDataKinds.Phone.NUMBER + " = ?";
        String[] selectionArgs = { number };
        Cursor cursor = contentResolver.query(uri, projection, selection, selectionArgs, null);

        if (cursor.moveToFirst())
        {

            contactName = cursor.getString(cursor.getColumnIndexOrThrow(PhoneLookup.DISPLAY_NAME));
            cursor.close();
            return contactName;
        }
        else
        {
            cursor.close();
            return null;
        }
    }

Try:

String selection = "REPLACE (" + ContactsContract.CommonDataKinds.Phone.NUMBER + ", \" \" , \"\" ) = ?";

See replace function.
