Retrieve Contact Phone Number From URI in Android

Question

I am trying to get the contact's phone number after I have retrieved their ID number from the built-in activity. However, whenever I query the database using the cursor in my code below -- I get zero rows returned even though there is a mobile number for the contact I have selected.

Can anyone point me in a better direction or show an example of how to get the contact's phone number AFTER getting their userID?

My code:

    private Runnable getSMSRunnable() {
    return new Runnable() {
    public void run() {
    Intent i = new Intent(Intent.ACTION_PICK,
      ContactsContract.CommonDataKinds.Phone.CONTENT_URI);
    startActivityForResult(i, CONTACTS_REQUEST_CODE);
   }
  };
 }

Returns the Log output

content://com.android.contacts/data/6802

From which i pass the ID (6802) into a method which is designed to return the phone number from the ID with the given type (in this case ContactsContract.CommonDataKinds.Phone.TYPE_MOBILE)

public static String getContactPhoneNumberByPhoneType(Context context, long contactId, int type) {
    String phoneNumber = null;

    String[] whereArgs = new String[] { String.valueOf(contactId), String.valueOf(type) };

    Log.d(TAG, String.valueOf(contactId));

    Cursor cursor = context.getContentResolver().query(
            ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
            null,
            ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ? and "
                    + ContactsContract.CommonDataKinds.Phone.TYPE + " = ?", whereArgs, null);

    int phoneNumberIndex = cursor
            .getColumnIndexOrThrow(ContactsContract.CommonDataKinds.Phone.NUMBER);

    Log.d(TAG, String.valueOf(cursor.getCount()));

    if (cursor != null) {
        Log.v(TAG, "Cursor Not null");
        try {
            if (cursor.moveToNext()) {
                Log.v(TAG, "Moved to first");
                Log.v(TAG, "Cursor Moved to first and checking");
                phoneNumber = cursor.getString(phoneNumberIndex);
            }
        } finally {
            Log.v(TAG, "In finally");
            cursor.close();
        }
    }

    Log.v(TAG, "Returning phone number");
    return phoneNumber;
}

Which returns null for a phone number -- which means it cannot find the row that I am trying to access -- which means that something is wrong with my query -- however if I check a contact that has a mobile phone number -- how could I get a 0 row query?

Any help would be greatly appreciated. Thank you so much!

Answer 1

I found the answer.

The reason I was not getting any rows from the cursor was because I was using the line

ContactsContract.CommonDataKinds.Phone.CONTACT_ID

"The id of the row in the Contacts table that this data belongs to."

Since I was getting the URI from contacts table anyways -- this was not needed and the following should have been substituted. The ID was the one corresponding to the contact in the phone table not the raw contact.

ContactsContract.CommonDataKinds.Phone._ID

Exchanging the lines returned the correct results in the query. Everything seems to be working well at the moment.
