Question

I’d like to share a photo with caption pre-filled from my app via a share intent, on facebook.

I know how to share photo or how to share text, but how do I share them together?

Example code

Intent shareCaptionIntent = new Intent(Intent.ACTION_SEND);
    shareCaptionIntent.setType("image/*");

    //set photo
    shareCaptionIntent.setData(examplePhoto);
    shareCaptionIntent.putExtra(Intent.EXTRA_STREAM, examplePhoto);

    //set caption
    shareCaptionIntent.putExtra(Intent.EXTRA_TEXT, "example caption");
    shareCaptionIntent.putExtra(Intent.EXTRA_SUBJECT, "example caption");

    startActivity(Intent.createChooser(shareCaptionIntent,getString(R.string.share)));

If a set type to image/* then a photo is uploaded without the caption prefilled. If a set it to text/plain only the caption is uploaded without the photo…..

My guess is that the issue is that the Android Facebook App doesn’t look for Intent.EXTRA_TEXT when it filters an ACTION_SEND Intent with type image/* for photo uploading. So this issue could be resolved if the Android Facebook App looked for that value, and if present, inserted it as the caption of the image.

Answer 1

Add this line to your existing codes:

shareCaptionIntent.putExtra(Intent.EXTRA_TITLE, "my awesome caption in the EXTRA_TITLE field");

There is no clearly defined differences among EXTRA_TITLE, EXTRA_SUBJECT and EXTRA_TEXT. So there is no clear share protocol. We could always try them all. 🙂
