I've seen the "share via" dialogs that are in apps like TFLN (texts from last night). Looks like this: 
I am looking to share text. Can someone point me in the right direction? Is this done with intents?

This is indeed done with Intents.
ReplyDeleteFor sharing an image, like in the example picture, it would be something like this:
Intent share = new Intent(Intent.ACTION_SEND);
share.setType("image/jpeg");
share.putExtra(Intent.EXTRA_STREAM,
Uri.parse("file:///sdcard/DCIM/Camera/myPic.jpg"));
startActivity(Intent.createChooser(share, "Share Image"));
For text you would use something like:
Intent share = new Intent(Intent.ACTION_SEND);
share.setType("text/plain");
share.putExtra(Intent.EXTRA_TEXT, "I'm being sent!!");
startActivity(Intent.createChooser(share, "Share Text"));
Yes. You need to provide an Activity with an intent filter that can handle objects of the MIME Type image/jpeg (say, if you wanted to support sharing JPEG images), and and action of presumably ACTION_SEND.
ReplyDeleteMany of the built-in Android apps are open-source, you can check the manifest file of the Messaging app to see what intent filters it is using.
