После нажатия кнопки сбой приложения для приложения

Question

Я добавил логин в свое приложение. Теперь моя начальная деятельность - это LoginActivity. Каждый раз, когда я заполнял свои учетные данные для входа в приложение, мое приложение рушится, когда я нажимаю кнопку входа. Это моя ошибка Вход в систему:

это мой MainActivity

общественного класса MainActivity расширяет AppCompatActivity реализует NavigationView.OnNavigationItemSelectedListener, OnMapReadyCallback { личное TextView txtName; частный TextView txtEmail; приватная кнопка btnLogout;

private SQLiteHandler db; 
private SessionManager session; 

private GoogleMap googleMap; 

SupportMapFragment sMapfragment; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    txtName = (TextView) findViewById(R.id.name); 
    txtEmail = (TextView) findViewById(R.id.email); 

    // SqLite database handler 
    db = new SQLiteHandler(getApplicationContext()); 

    // session manager 
    session = new SessionManager(getApplicationContext()); 


    // Fetching user details from sqlite 
    HashMap<String, String> user = db.getUserDetails(); 

    String name = user.get("name"); 
    String email = user.get("email"); 

    // Displaying the user details on the screen 
    txtName.setText(name); 
    txtEmail.setText(email); 

    // Logout button click event 



















    sMapfragment = SupportMapFragment.newInstance(); 

    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar); 
    setSupportActionBar(toolbar); 





    DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout); 
    ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
      this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close); 
    drawer.setDrawerListener(toggle); 
    toggle.syncState(); 

    NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view); 
    navigationView.setNavigationItemSelectedListener(this); 
    sMapfragment.getMapAsync(this); 

    if (ContextCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED) { 
     if (ActivityCompat.shouldShowRequestPermissionRationale((Activity) this, android.Manifest.permission.ACCESS_FINE_LOCATION)) { 
      AlertDialog.Builder alertBuilder = new AlertDialog.Builder(this); 
      alertBuilder.setCancelable(false); 
      alertBuilder.setTitle("Permission necessary"); 
      alertBuilder.setMessage("Fine Location is necessary"); 
      alertBuilder.setPositiveButton(android.R.string.yes, new DialogInterface.OnClickListener() { 

       @TargetApi(Build.VERSION_CODES.JELLY_BEAN) 
       public void onClick(DialogInterface dialog, int which) { 
        ActivityCompat.requestPermissions(MainActivity.this, new String[]{android.Manifest.permission.ACCESS_FINE_LOCATION}, 1234);

      AlertDialog alert = alertBuilder.create(); 
      alert.show(); 
     } else { 
      ActivityCompat.requestPermissions(MainActivity.this, new String[]{android.Manifest.permission.ACCESS_FINE_LOCATION}, 1234); 
     } 

    }
