pass arraylist via implicit intent

Question

I want to pass my arraylist via implicit intent just because I want to send my data in listview via whatsapp. Here is my code

public void save()
{

   ArrayList<String> arrayList= new ArrayList<String>(Arrays.asList(combination));


    Intent intent= new Intent(Intent.ACTION_SEND);
    intent.setType("text/plain");

    intent.putStringArrayListExtra(Intent.EXTRA_TEXT,arrayList);

    startActivity(intent);
}

save() is a method that gets called when user presses SHARE button. But it actually doesn't pass anything to whatsapp.

Concatenate your strings together into one single string. Then, use that as your EXTRA_TEXT value. No application will be expecting an ArrayList<String> as the EXTRA_TEXT value, and so your existing code will not work.

String string= Arrays.toString(arrayList); and then intent.putExtra(Intent.EXTRA_TEXT,string); . This is what I have already tried . It works but give you a single line ...I want the actual list , not a line – Dhoni Singh May 07 '16 at 17:37
@DhoniSingh: Well, the accepted answer on the question that I linked to shows joining them as separated by tabs. You are welcome to use `\n` instead of `\t` to join them by newlines. Since this is Android, you are also welcome to [use `TextUtils.join('\n', arrayList)`](http://developer.android.com/reference/android/text/TextUtils.html#join%28java.lang.CharSequence,%20java.lang.Iterable%29), if you prefer. Expecting WhatsApp to do that work for you, though, is unrealistic. – CommonsWare May 07 '16 at 17:40
