For redlining, a copy of the document will be created and opened for editing in any installed 3rd party application that can handle the "intent".
When the user accepts the change, the creation of a new document object classified as a redlined document will be triggered (as described in "Creating Documents in {{UBIK}} Android").
=== Editing Documents ===
Then, the Content Browser for the Document object provides an "Edit File" action item in the context aware action bar.

==== Editing an already downloaded file ====
If the file was already downloaded, the user is asked to choose any installed 3rd party application for editing the respective file.
In case no such app is installed, editing the document is not possible.

When the editing was finished, the new file is marked as changed and will be committed automatically if Automatic Sync mode is active, else the user can commit manually.
If so, the editing proceeds as described for an already downloaded file.
