How to Control BitmapFactory FileNotFoundException with ListAdapter

Question

I'm making an Activity where I show the contact list of the phone by their names and their photos. I use a Cursor and a Managedquery with a ListAdapter to adapt everything to a layout.

It works nice, but I see in Logcat an error related with those who don't have picture and I'd like to control them, showing the android default no-photo icon but I haven't found a way to do it.

Here is an example:

Example of the contact list generated

The blue blur are the names. Hidden to preserve their identities :P

Here's the code:

Contactos.java

protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_contactos);

        //Llamamos función para conseguir todos los contactos.
        Cursor cursor = getContacts();
        startManagingCursor(cursor);
        // Llenamos la ListView con los contactos del teléfono
        try {
            ListAdapter infoContacto = new SimpleCursorAdapter(this,R.layout.contacto,
                    cursor,new String[] {ContactsContract.Contacts.PHOTO_THUMBNAIL_URI,ContactsContract.Contacts.DISPLAY_NAME},
                    new int[] {R.id.foto, R.id.nombreContacto}, 0);
            setListAdapter(infoContacto);
        }catch(Exception e){
            Log.d("Excepcion",e.toString());
        }

    }
private Cursor getContacts() {
            Uri contacto = ContactsContract.Contacts.CONTENT_URI;
            /* Seleccionamos la información que necesitamos. ID SIEMPRE NECESARIO. */
            String[] projection = new String[] {ContactsContract.Contacts._ID,ContactsContract.Contacts.PHOTO_THUMBNAIL_URI,ContactsContract.Contacts.DISPLAY_NAME};
            /* Los ordenamos por nombre */
            String selection = ContactsContract.Contacts.IN_VISIBLE_GROUP;
            String[] selectionArgs = null;
            String ordenarPorNombre = ContactsContract.Contacts.DISPLAY_NAME + " COLLATE LOCALIZED ASC";
            /* Devolvemos los contactos */
            return managedQuery(contacto, projection, selection, selectionArgs,
                    ordenarPorNombre);
     }

Logcat

I guess I should put an if statement somewhere before the projection definition to check if is a valid URI or file and not a directory, but how and where?

And one last question, should I use the current method or better change it to a getContentResolver().query(blablabla...)??

Thanks for your time.

To specify contacts image for those that have none on the phone, you will need to setViewBinder() method of your SimpleCursorAdapter and check if image is null, then place default no-photo image (only Image I can find in Android system resources is android.R.drawable.ic_contact_picture shown below)

enter image description here

Regarding your last question, I think it will not make much difference (your code is already working). But if you will edit the contact data, I think you will have to use a ContentResolver.

Many thanks mate! That was what I was looking for to control the contact images. — arkanos, Jun 09 '13 at 22:26
