I have a RecyclerView which needed to be sent/shared with external apps like WhatsApp etc. Using ShareActionProvider to achieve this. Have created a menu and inflated in the overflow area in ToolBar using SharedActionProvider.
sample code.
public void prepareShareIntent() {
shareIntent = new Intent();
shareIntent.setAction(Intent.ACTION_SEND);
shareIntent.putExtra(Intent.EXTRA_TEXT, "Sample Text.");
shareIntent.setType("text/plain");
startActivity(Intent.createChooser(shareIntent, getResources().getText(R.string.share)));
}
If data sharing between internal activities, we usually pass objects/object list by serialising/ Parcelable or using gson , no issue here since we can easily parse the data in the receiving activity. But in case, if I need to share a list Object to external apps what should be done. Does the external apps interpret as only specific types?
Appreciate the possible approaches. Thanks in advance.

That is not possible. First, you cannot pass a View to another process. Second, WhatsApp and other apps would not know what to do with it.

You cannot convert a RecyclerView into a Serializable, a Parcelable, or JSON. You might be able to convert the model data that the RecyclerView uses into one of those things, but third-party apps (e.g., WhatsApp) may not know what to do with it.

Correct. The MIME type of the ACTION_SEND Intent needs to be the MIME type of the content shared via EXTRA_TEXT or EXTRA_STREAM.
I recommend that you spend some time thinking about what exactly you expect WhatsApp to do when you share content with it, where that content is somehow tied to a RecyclerView. For example, if you want WhatsApp to send a screenshot of the RecyclerView to somebody, then you should be sharing a screenshot of the RecyclerView, not the RecyclerView itself.
