upload captured image to Cloudinary directly in An

问题:

I want to capture a picture and upload it to Cloudinary directly. How can I know the name of the pic to set it at the upload statement cloudinary.uploader().upload("nameofthepic", Cloudinary.emptyMap());.

Here is my code:

public class Camera extends ActionBarActivity implements View.OnClickListener {
    Button b;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.camera);

        b= (Button) findViewById(R.id.button);
        b.setOnClickListener(this);

    }
    public static final int TAKE_PHOTO_REQUEST = 0;

    @Override
    public void onClick(View v) {
        Intent takePhotoIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
        startActivityForResult(takePhotoIntent, TAKE_PHOTO_REQUEST);
        Map config = new HashMap();
        config.put("cloud_name", "dkepfkeuu");
        config.put("api_key", "552563677649679");
        config.put("api_secret", "7n8wJ42Hr_6nqZ4aOMDXjTIZ4P0");
        Cloudinary cloudinary = new Cloudinary(config);

        try {
            cloudinary.uploader().upload("", Cloudinary.emptyMap());
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

The order is like this: Take picture->save to file->upload to cloudinary Here is the code:

File photoFile;

     @Override
        public void onClick(View v) {
            Intent takePhotoIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
            if (takePhotoIntent.resolveActivity(getPackageManager()) != null) {
                // Create the File where the photo should go
                photoFile = null;
                try {
                    photoFile = createImageFile();
                } catch (IOException ex) {
                    // Error occurred while creating the File
                }
                // Continue only if the File was successfully created
                if (photoFile != null) {
                    takePhotoIntent.putExtra(MediaStore.EXTRA_OUTPUT,
                            Uri.fromFile(photoFile));
                    startActivityForResult(takePictureIntent, REQUEST_TAKE_PHOTO);
                }
            }
        }
@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        if (requestCode == REQUEST_TAKE_PHOTO) {
            if (resultCode == RESULT_OK) {
                //File to upload to cloudinary
                Map config = new HashMap();
                config.put("cloud_name", "dkepfkeuu");
                config.put("api_key", "552563677649679");
                config.put("api_secret", "7n8wJ42Hr_6nqZ4aOMDXjTIZ4P0");
                Cloudinary cloudinary = new Cloudinary(config);
                try {
                    cloudinary.uploader().upload(photoFile.getAbsolutePath(),          Cloudinary.emptyMap());
                } catch (IOException e) {
                    e.printStackTrace();
                }

            } else if (resultCode == RESULT_CANCELED) {
                // User cancelled the image capture
                //finish();
            }
        }
    }

    private File createImageFile() throws IOException {
            // Create an image file name
            String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
            String imageFileName = "capturedImage";
            File storageDir = Environment.getExternalStoragePublicDirectory(
                    Environment.DIRECTORY_PICTURES);
            File image = File.createTempFile(
                    imageFileName,  /* prefix */
                    ".jpg",         /* suffix */
                    storageDir      /* directory */
            );

            // Save a file: path for use with ACTION_VIEW intents
            return image;
        }

So you are actually uploading photoFile which is the actually captured image.

Its nice to put the upload function along with some image transformations(scale,resize) in AsyncTask because camera images in modern handsets are quite big(in size).

Hope it helps.
