The only part of internal memory you can write to is your apps designated data folder, which like you said is removed upon app uninstall.

The only place you can persist files indefinitely is the external storage.

If you only want to store "text" so lemme introduce "SharedPreferences"

heer some example code

//save
SharedPreferences prefs = getSharedPreferences("MyPrefs", 0);
SharedPreferences.Editor editor = settings.edit();
editor.putString("key", "value");
editor.commit();

//restore
SharedPreferences prefs = getSharedPreferences("MyPrefs", 0);
String key = prefs.getString("key", "default value");

FYI
please read this tutorial

SharedPreferences are not limited to only text. Any primitive type can be stored there. I was under the impression he wanted a controlled file, not a database that can only accessed with your app, but if I am wrong about this assumption, then this would be a great solution for him/her.

Dear Jonbonazza,

Thank you for your response. But this method-wise we can store text files in internally.

but if my app will uninstall my text files also removed from my device. So I want to store

text files even my app will uninstall.

Thanks&Regards,
