Android Intent pass Object between different different apps Code Answer

I have this Activity (the MainActivity, from package package com.example.myapplication) that receives an Intent of class “BeanValidacion“.

protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Bundle willirex = getIntent().getExtras();

        if(willirex!=null)
        {
            BeanValidacion datos = (BeanValidacion) willirex.get("paramIn");

            Toast.makeText(MainActivity.this,datos.getIdNumber(),Toast.LENGTH_LONG).show();


        }

And I want to call it with a different APK (package com.adon.intents) and send an Intent, as I do with String Intents, but this time, I want to send an object of class “BeanValidacion“:

protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        BeanValidacion datos = new BeanValidacion();
        datos.setIdNumber("12345");
        Intent next = new Intent();
        next.setClassName("com.example.myapplication", "com.example.myapplication.MainActivity");
        next.putExtra("paramIn", datos);

        startActivity(next);

    }

When I execute the com.adon.intents APK to send the intent, I got this error on com.example.myapplication:

ClassNotFoundException reading a Serializable object (name = com.adon.intents.BeanValidacion

In this line:

Toast.makeText(MainActivity.this,datos.getIdNumber(),Toast.LENGTH_LONG).show();

This doesn’t happen when sending just a String, but I am having problems solving this one.

You should put the BeanValidacion.java file in the exact package hierarchy com.adon.intents.BeanValidacion on the second app. Also, both classes should have the same serialVersionUID.
