The most simple way to achieve this is by using SharedPreferences

To detect when the user edits the value of the editText, use addTextChangedListener, and immediately store it using SharedPreferences The code for this is as following,

editText.addTextChangedListener(new TextChangedListener<EditText>(editText) {
        @Override
        public void onTextChanged(EditText target, Editable s) {
            SharedPreferences.Editor editor = save.edit();
            editor.putString("KEY", editText.getText().toString()).apply();
        }
    });

The above code will save the editText value. To retrieve the stored value when the user opens the app later, the following code shall be used,

SharedPreferences editTextPref = getApplicationContext().getSharedPreferences("KEY", Context.MODE_PRIVATE);
editText.setText(editTextPref.getString("KEY"));
