How can i send object from one application to another in android

I want to send a list of object form a class that I have created through intent from one application, and get this list in one other.

I tried this :

Intent i = new Intent();

i=getActivity().getPackageManager().getLaunchIntentForPackage(getString(R.string.package_app));

ArrayList<MyClass> list = new ArrayList<MyClass>();

i.setAction(Intent.ACTION_SEND);

i.putExtra(Intent.EXTRA_TEXT, list);

i.setType("text/plain");

And to get it i have done this :

Intent receivedIntent = getIntent();

ArrayList<MyClass> getList = new ArrayList<MyClass>();

getList=(ArrayList<MyClass>)receivedIntent.getSerializableExtra(Intent.EXTRA_TEXT);

startActivity(i);

But i have an exception when i want to get the list

According to your stack trace you need to make the MyClass serializable.

Then you can pass the list of MyClass to second activity.

This can be as shown below:

class MyClass implements Serializable
{
//your implementation
}

In your 1st activity you need to do something like this:

Intent i = new Intent(context,secondactivity.class);

ArrayList<MyClass> list = new ArrayList<MyClass>();
i.putExtra("listdata",list);

In your 2nd activity you need to do something like this:

Intent receivedIntent = getIntent();

getList=receivedIntent.getSerializableExtra("listdata",null);

Hope this helps...
