Try something like below. Put below code in your main activity from where you want to pass the data.

Intent i = new Intent("com.your_app_package_name.your_app_name.ActivtiyAlpha");
i.putExtra("KEY_DATA_EXTRA_FROM_ACTV_B", myString);
// add extras to any other data you want to send to b

and in other activity.

Bundle b = getIntent().getExtras;
if(b!=null){
    String myString = b.getString("KEY_DATA_EXTRA_FROM_ACTV_B");
    // and any other data that the other app sent
}

the class must implement parcelable and then you can pass the custom object to another class – Raghunandan Feb 24 '14 at 12:38

Implementing Parcelable might seems like a good fit, but it would cause issues if you ever modify your object structure. Both applications would need to be up-to-date, or the de-serialization would crash.

I would go for a JSON or XML serialization, and pass the String as an Intent extra.
