hi developing app shares picture in via share contract in windows phone 8.1. code is

datatransfermanager datatransfermanager = datatransfermanager.getforcurrentview(); datatransfermanager.datarequested += new typedeventhandler<datatransfermanager, datarequestedeventargs>(this.datarequested);

and

private async void datarequested(datatransfermanager sender, datarequestedeventargs args) {     datarequest request = args.request;     request.data.properties.title = "unscramble this";     request.data.properties.description = "";     request.data.settext(string.format("scrambled word {0} , clue {1}. me unscramble \r\n(via unscramble plus windows phone)",scrambledstring.toupper(),selectedmeanings.toupper()));     datarequestdeferral deferral = request.getdeferral();      // make sure call complete on deferral.     try     {         //storagefile logofile = await package.current.installedlocation.getfileasync("assets\\logo.png");          storagefile imagefile = await knownfolders.pictureslibrary.getfileasync("pic.png");         list<istorageitem> storageitems = new list<istorageitem>();         storageitems.add(imagefile);         request.data.setstorageitems(storageitems);     }         {         deferral.complete();     }  }

where show share contract below (including facebook, mail apps) enter image description here

but if see in sendtiment app windows phone (http://www.windowsphone.com/en-us/store/app/sendtiment-cards/9c389cc5-5c00-4f8e-8bd4-e6fbb5040c24) shows many apps viber, whatsapp, twitter.

enter image description here

edit: (addition) when remove request.data.settext(string.format("scrambled word {0} , clue {1}. \r\n(via unscramble plus windows phone)",scrambledstring.toupper(),selectedmeanings.toupper())); line, shows onedrive.

this might help, make sure kind of data sharing, app show if content type matches,

for example whatsapp show if sharing video,images not phone contact.
