First, I would temporarily write your bitmap to external storage, and use that to debug your basic share-the-file logic.

Then, implement a ContentProvider, where you override openFile() and serve up your byte[] of PNG (or JPEG or whatever). Then use a content:// Uri pointing at your ContentProvider in your ACTION_SEND Intent, instead of a Uri pointing at external storage.

This sample project demonstrates the basic structure. In my case, I am serving a file from assets, rather than from memory, so you would change that portion of the logic. Also, I am using the ContentProvider for an ACTION_VIEW request instead of ACTION_SEND, so there would need to be changes there.

How well this will work will depend on how quickly the third-party app will read in the contents from your provider and whether you can arrange to hold onto the bitmap in memory that long.
