Android Select pictures or photos to upload to the server (including upload parameters)

in the 9ria forum see, haven't tested, first mark to share with you. Recently, to get a project, you need to upload a photo album and photos, not negative, finally finished! However, it is necessary to explain, in fact, many of the online pictures of the tutorial, are thumbnails are not very clear, so you need to call the camera, in advance to generate an address, to identify the image of the picture Uri Specific upload code:

2. Choose the image interface, mainly related to two ways: select pictures and timely photo pictures
