public class Login extends AppCompatActivity {
String mobile, password;
TextView forgot_password;
EditText mobile_num,pass;
Button log_btn;

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_login);
    Login.this.setTitle("Vendor Screen");
    builder = new AlertDialog.Builder(Login.this);
    forgot_password = findViewById(R.id.forgot_pwd);
    log_btn = findViewById(R.id.login_btn);
    mobile_num = findViewById(R.id.mobile);
    pass = findViewById(R.id.password);
    forgot_password.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Intent i = new Intent(Login.this,Forgot_password.class);
            startActivity(i);
        }
    });

    //Login Page

Answer 1

Вы можете следовать этой основной идее:

if (Integer.parseInt(jobject.getString("status")) == 200 {
    ...
    SharedPreferences preferences = 
        PreferenceManager.getDefaultSharedPreferences(this);
    SharedPreferences.Editor editor = preferences.edit();

    var userData = jobject.getObject("userdata");
    editor.putInt("ID", userData.getInt("ID"));
    editor.putString("FIRM_NAME", userData.getString("FIRM_NAME"));
    // etc...
    editor.commit();
    ...
}

Тогда в вашей другой деятельности:

SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(this);
var id = preferences.getInt("ID", -1);
var firmName = preferences.getString("FIRM_NAME", null);

Где -1 и null выше будут значения, указанные, еслинастройки не найдены.
