Android Studio AsyncTask get Result to other Activity

Question

I have an Activity where I want to show my received date from a Database. Showing my result in a TextView, that's no problem. But I also want to save my received Data in an String value. My Code: Main Activity:

db3 = new DatabaseC529(C529chooseActivity.this,tvC529Cthirdoccupied,tInt3);
db3.execute(methode, date, timeId3);

DatabaseC529: Constructor:

public DatabaseC529(Activity activity, TextView textView, String myValue){  
        this.activity = activity;
        this.ctx = activity;
        this.textView = textView;
        this.myValue = myValue;}

...

protected void onPostExecute(String result) {super.onPostExecute(result);
this.textView.setText(result);
this.myValue = result;
 }

After AsyncTask is completed, the Result is shown in the TextView. But I also want to have the Value stored in my String "tInt3". I created a button (just to check if the Value is stored) to get the content of tInt3 after AsyncTask is completed, but it always shows "null". Code Button:

public void button1 (View view){if(view.getId() == R.id.button1){
        Toast.makeText(this, " " +tInt3, Toast.LENGTH_SHORT).show();
    }

Can somebody please help me???

You can use shared preference to store your string data and then use it.

Saving values:

SharedPreferences.Editor editor = getSharedPreferences(yourpref, MODE_PRIVATE).edit();
 editor.putString("tInt3", Result);
 editor.apply();

Getting Values:

SharedPreferences prefs = getSharedPreferences(yourpref, MODE_PRIVATE);
 String value= prefs.getString("tInt3", "null");
