title: How to upload file to Amazon S3 from Android
body: <p><strong>Hi, I have integrated these codes such that I will be able to upload file rather than photo selected to AmazonS3, but for some parts, they are still part of uploading image suchs as <em>"intent.setType("image/</em>");"* 
  Please let me know if anything can be changed to these codes to have my file uploaded to AmazonS3 successfully. Thank you very much.</strong></p>
