Custom Content Provider - openInputStream(), openOutputStream()
<p>The content provider / resolver APIs provide a complicated, but robust way of transferring data between processes using an URI and the openInputStream() and openOutputStream() methods. Custom content providers have the ability to override the openFile() method with custom code to effectively resolve an URI into a Stream; however, the method signature of openFile() has an ParcelFileDescriptor return type and it is not clear how one might generate a proper representation for dynamically generated content to return from this method.</p>

<p>Are there examples of implementing ContentProvider.openFile() method for dynamic content in the existing code base? If not can you suggest source code or process for doing so? </p>
