Android Intent pass Object between different different apps Code Answer

Hello Developer, Hope you guys are doing great. Today at Tutorial Guruji Official website, we are sharing the answer of Android Intent pass Object between different different apps without wasting too much if your time.

The question is published on by Tutorial Guruji team.

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.

Regards

Answer

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.
