How to pass ArrayList object from one Activity to another Activity using Intent?

Question

I have a ArrayList documents and I want to send this file to another Activity. but How to get This value in SecondActivity

What I tried is In First Activity

 private ArrayList<File> documents;
Intent selectLabInt = new Intent(FirstActivity.this, SecondActivity.class);

 selectLabInt.putExtra("patient_name", patientNameStr);
 selectLabInt.putExtra("referal_notes", referalNotesStr);
 selectLabInt.putExtra("fileList",documents);

 startActivity(selectLabInt);

So you want to pass string type of data or object of ArrayList i.e. document? — Mrunal, Mar 04 '16 at 06:28

If your File is serializable,then you can pass the ArrayList like this:

In the sending Activity:

ArrayList<File> documents= new ArrayList<File>();
intent.putExtra("documents", documents);

In the receiving Activity:

ArrayList<File> documents = (ArrayList<File>)getIntent().getSerializableExtra("documents");

File class implements Serializable internally. – Sabya Sachi Mar 04 '16 at 06:31

You need to make File class parcelable so that you can pass arraylist of that class in intent via putParcelable.

here is example of same https://stackoverflow.com/a/6681784/942224
