I am doing in this code: message receiving,filtering and getting then sending data to a sql server. I need the category_id from mysql database. Then i will use it in CallAPI as ide . I took the data from my mysql database but i couldn't transfer the data one class to another. So how can i transfer the data from one class to another?
I solved my problem and updated it i hope it can help to another peoples.

hi you can send parameters class A to class B is so way...
you can use constructor like this
public class test {
public test(String p){...}
}
and you can use intent
you can use shared preference in
learn with this site Shared preference save data from class A and read class B
and you must be careful because when you give data from server thread is different Ui thread !
private SharedPreferences mPreference;
mPreference = getSharedPreferences("Share", Context.MODE_PRIVATE);
// save data
mPreference.edit()
.putBoolean("test", category_id)
.apply();
// read data
mPreference.getString("test", defaultSTR);
You can use transfer your data in different class by using database , shared preference and intents.
If You want to transfer data from class A to B by intent then
In class A
Intent intent = new Intent(getApplicationContext(), SecondActivity.class);
intent.putExtra("key_name", value);
startActivity(intent);
and In class B for getting the transferred data
Intent intent=new getIntent();
String s=intent.getExtras().getString("key_name");
