How to hide my custom Acount Manager from Settings UI

Question

My requirement is to add contact to my custom account and this is working accordingly.

The Settings -> + Add account screen shows the list of all applications which provides account management; i.e., my application name is also shown there. However, my requirement is not to display my application on that list.

Here are the classes involved:

AccountManagerActivity.java

public class AccountManagerActivity extends AccountAuthenticatorActivity {
EditText etName, etPhone;
Button btnSave;
String strName, strPhone;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    etName = (EditText) findViewById(R.id.etName);
    etPhone = (EditText) findViewById(R.id.etPhone);
    btnSave = (Button) findViewById(R.id.btnSave);
    btnSave.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {

            if (etName.getText().toString() == null|| etName.getText().toString().equalsIgnoreCase("")|| etPhone.getText().toString() == null|| etPhone.getText().toString().equalsIgnoreCase("")) 
            {
                Toast.makeText(getApplicationContext(),"Enter Name And Phone", Toast.LENGTH_LONG).show();
            } 
            else 
            {
                strName = etName.getText().toString();
                strPhone = etPhone.getText().toString();
                addContact();
                etName.setText("");
                etPhone.setText("");
                Toast.makeText(getApplicationContext(), "Contact Added",Toast.LENGTH_LONG).show();
            }
        }
    });


    AccountManager manager = AccountManager.get(this);

    String accountName = "Contact";
    String password = "NULL";
    String accountType = "com.example.contact";

    final Account account = new Account(accountName, accountType);
    manager.addAccountExplicitly(account, password, null);

    final Intent intent = new Intent();
    intent.putExtra(AccountManager.KEY_ACCOUNT_NAME, accountName);
    intent.putExtra(AccountManager.KEY_ACCOUNTS, accountName);
    intent.putExtra(AccountManager.KEY_ACCOUNT_TYPE, accountType);
    intent.putExtra(AccountManager.KEY_AUTHTOKEN, accountType);
    this.setAccountAuthenticatorResult(intent.getExtras());
    this.setResult(RESULT_OK, intent);

}


private void addContact() {
    // TODO Auto-generated method stub

    ArrayList<ContentProviderOperation> ops = new ArrayList<ContentProviderOperation>();
    int rawContactInsertIndex = ops.size();
    ops.add(ContentProviderOperation.newInsert(RawContacts.CONTENT_URI)
            .withValue(RawContacts.SYNC1, null)
            .withValue(RawContacts.SYNC2, null)
            .withValue(RawContacts.SYNC3, null)
            .withValue(RawContacts.SYNC4, null)
            .withValue(RawContacts.ACCOUNT_TYPE,  "com.example.contact")
            .withValue(RawContacts.ACCOUNT_NAME, "contact").build());
    ops.add(ContentProviderOperation
            .newInsert(Data.CONTENT_URI)
            .withValueBackReference(Data.RAW_CONTACT_ID,
                    rawContactInsertIndex)

                                                                // person
            .build());
    ops.add(ContentProviderOperation
            .newInsert(Data.CONTENT_URI)
            .withValueBackReference(ContactsContract.Data.RAW_CONTACT_ID,
                    rawContactInsertIndex)
            .withValue(Data.MIMETYPE, Phone.CONTENT_ITEM_TYPE)
            .withValue(Phone.NUMBER, strPhone) // Number of the person

    try {
        ContentProviderResult[] res = getContentResolver().applyBatch(
                ContactsContract.AUTHORITY, ops);
    } catch (RemoteException e) {
        Log.e("RemoteException", "" + e);
    } catch (OperationApplicationException e) {
        Log.e("OperationApplicationException", "" + e);

Answer 1

It is not possible to modify Setting app directly, as said by @shoe rat if you have access or any link to OEM/ROM maker then it might be possible.

Answer 2

Unfortunately, you can't do that.

Every authenticator needs to be on that list, to keep the user aware to all the services he's connected to, allowing him to disconnect anytime with a standard way (not needing to find the disconnect button on a specific app/service).
