Transition of activities with serializable classes (getIntent problem)

Question

I have a problem while passing a serializable class. I insert it into the Bundle as follows.

public void voltarMain(View view) {
    Intent myIntent = new Intent(getApplicationContext(), MainActivity.class);

    myIntent.putExtra("Cliente", cliente);

    startActivity(myIntent);
    finish();
}

When I try to receive it in the second Activity it is in the Bundle but gives me an error of "java.lang.Nullpointerexception: Attempt to invoke virtual method 'int java.math.Roundingmode.ordinal()' on a null Object Reference"

This is how I try to get it.

This is the error obtained

Note: On a tablet Huawei Mediapad T5 (android 8.0) works correctly while this error comes to me in Samsung A7 2018 (android 9.0)

Answer 1

Instead of creating a Bundle and putting in your Input, place your client object with the putExtra function of the Intent class:

Intent intent = (...)
i.putExtra("Cliente", cliente);

P.S.: use the stack overflow code block itself, which will adapt to the screen size, and allows people to copy the text easily.
