Uploading image using Dropbox API, Android

Question

After capturing an image, I'm unsure of how to upload the bitmap as a file. I get the bitmap this way:

    protected void onActivityResult(int requestCode, int resultCode, Intent data) {    
        if(requestCode == CAM_REQUEST_CODE){
             if(resultCode == RESULT_OK){
                  final Bitmap image = (Bitmap)data.getExtras().get("data");
             }
        }
    }

Using Dropbox API, a file is uploaded this way:

File file = new File("working-draft.txt");
FileInputStream inputStream = new FileInputStream(file);
Entry response = mDBApi.putFile("/magnum-opus.txt", inputStream,
                            file.length(), null, null);
Log.i("DbExampleLog", "The uploaded file's rev is: " + response.rev);

Any help on this is greatly appreciated.

The `putFile` method takes an `InputStream` so if you can get the data into an `InputStream` directly, you can avoid writing it to a file in between. — Greg, May 28 '15 at 00:02

Here's one way you could do it:

Create a ByteArrayOutputStream
Call Bitmap.compress() to write the JPEG/PNG bytes to outputstream
Create a ByteArrayInputStream from the byte array you just output
Use that input stream for your putFile() method
Use the array size for your file length

I would be cautious about memory, though. It it was me, I'd try to find a way to return the bitmap source in the activity result instead of the actual bitmap.
