upload and deleting files to/from sharepoint document libraries

Hello,

I am having trouble uploading files to document libraries from android platform. I have used the http put method to hit the url. The file is appearing in the doc library but i am unable to view it.Encoding is utf 8. I think there is some trouble with the content type.

This is my url from Uploading a new file:

http://mysite.sharepoint.com/Site/My%20Documents/SAAS3.docx

I also have trouble deleting the files. When i delete it from my android app, its being removed completely and is not moved to recycle bin.I have tried hitting the url both in http delete as well as http post methods.

This is my url for deleting a file:

http://mysite.sharepoint.com/Site/_api/web/lists/getbyid('list id')/Items(item id)/recycle()
