Android Studio Delete contact

Question

So basically i have a function which deletes the contact from the phone:

String[] args = new String[]{number};

    try {

        ArrayList ops = new ArrayList();
        // if id is raw contact id
        ops.add(ContentProviderOperation.newDelete(ContactsContract.RawContacts.CONTENT_URI).withSelection(ContactsContract.RawContacts._ID + "=?", args).build());
        // if id is contact id
       // ops.add(ContentProviderOperation.newDelete(ContactsContract.RawContacts.CONTENT_URI).withSelection(ContactsContract.RawContacts.CONTACT_ID + "=?", args).build());
        getContentResolver().applyBatch(ContactsContract.AUTHORITY, ops);
        Toast.makeText(this, "Contact Deleted", Toast.LENGTH_SHORT).show();


    } catch (Exception e) {

        Log.e("$$$$", "ERRORDELETE#133");
    }

I tried both options, if raw contact or if contact id, both doesn't work/

When i run the APP and the function activates the 'Contact Deleted' Shows and in the log:

05-24 15:40:16.444 6540-6540/com.assistme.meirovichomer.assistme E/ViewRootImpl: sendUserActionEvent() mView == null
05-24 15:40:16.464 6540-6679/com.assistme.meirovichomer.assistme V/RenderScript: Application requested CPU execution
05-24 15:40:16.474 6540-6679/com.assistme.meirovichomer.assistme V/RenderScript: 0xa14a7e00 Launching thread(s), CPUs 4

I am not sure if i just don't understand the log or i missed anything but when i enter the contact list on the phone the contact is still no it, therefore wasn't deleted. Would love to get some help, Thank you very much in advance!

try this.

for delete.

public static void deleteContact(ContentResolver contactHelper, String 
number) {
ArrayList<ContentProviderOperation> ops = new 
ArrayList<ContentProviderOperation>();
String[] args = new String[] { String.valueOf(getContactID(contactHelper, 
number))};
ops.add(ContentProviderOperatio.newDelete(RawContacts.CONTENT_URI).withSelecti
  on(RawContacts.CONTACT_ID + "=?", args).build());
 try {
  contactHelper.applyBatch(ContactsContract.AUTHORITY, ops);
  } catch (RemoteException e) {
  e.printStackTrace();
 } catch (OperationApplicationException e) {
e.printStackTrace();
}
}

and getid

private static long getContactID(ContentResolver contactHelper,String 
number) {
Uri contactUri = Uri.withAppendedPath(PhoneLookup.CONTENT_FILTER_URI, 
Uri.encode(number));
String[] projection = { PhoneLookup._ID };
Cursor cursor = null;
try {
cursor = contactHelper.query(contactUri, projection, null, null,null);
if (cursor.moveToFirst()) {
int personID = cursor.getColumnIndex(PhoneLookup._ID);
return cursor.getLong(personID);
}
return -1;
} catch (Exception e) {
e.printStackTrace();
} finally {
if (cursor != null) {
cursor.close();
cursor = null;
}
}
return -1;
}

It works well, thank you! wanted to ask if you could maybe explain why my code didn't work and this one does, would love to expend my knowlage, thx! — OHM, May 26 '17 at 09:51
