Home activity with nav drawer menu does not open after login

Question

I created a Login android app, connected to firebase Real time database and works perfectly (Users has been created successfully).

From LoginActivity, users must go to HomeActivity, which has a navigation drawer menu, but does not work.

I tried to change the activity destination, so after login, I tried to open a TrialActivity and works perfectly.

What could be the problem?

LoginActivity

public class LoginActivity extends AppCompatActivity {
    private EditText InputNumber, InputPaswd;
    private Button LoginBtn;
    private ProgressDialog loadingBar;
    private String parentDBName = "Users";
    private TextView AdminLink, NotAdminLink;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_login);

        InputNumber = (EditText) findViewById(R.id.login_phone_numb_input);
        InputPaswd = (EditText) findViewById(R.id.login_Password);
        LoginBtn = (Button) findViewById(R.id.login_btn);
        loadingBar = new ProgressDialog(this);
        AdminLink = (TextView) findViewById(R.id.admin_panel_link);
        NotAdminLink = (TextView) findViewById(R.id.not_admin_panel_link);

        LoginBtn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                LoginUser();
            }
        });

        AdminLink.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                LoginBtn.setText("Login Admin");
                AdminLink.setVisibility(View.INVISIBLE);
                NotAdminLink.setVisibility(View.VISIBLE);
                parentDBName="Admins";
            }
        });
        NotAdminLink.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                LoginBtn.setText("Login");
                AdminLink.setVisibility(View.VISIBLE);
                NotAdminLink.setVisibility(View.INVISIBLE);
                parentDBName="Users";
            }
        });
    }

    private void LoginUser() {
        String phone = InputNumber.getText().toString();
        String password = InputPaswd.getText().toString();

      //  InputNumber.setText("3791881336");
        //InputPaswd.setText("1234");

            loadingBar.setMessage("Please wait, loading");
            loadingBar.setCanceledOnTouchOutside(false);
            loadingBar.show();
            AllowAccessToAccount( phone, password);
        }
