How to upload image to Parse in android?

Question

I have been able to take a picture using a camera or take from a gallery and show it in an ImageView using this code. What I need to do now is to use that picture and upload it to Parse. I have been googling here and there to do this, and I haven't found the right way to do it. Can someone please help me with this? Is it possible to upload the image from the ImageView? Thank you.

protected Button mFromCamera;
protected Button mFromGallery;
protected ImageView mImageView;

private static final int CAMERA_REQUEST = 1888;
private static final int SELECT_PHOTO = 100;

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


//Initialize ImageView
mImageView = (ImageView) findViewById(R.id.ImgPrev);
//Initialize Camera
mFromCamera = (Button) findViewById(R.id.FromCamera);

//use camera
mFromCamera.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
        startActivityForResult(cameraIntent, CAMERA_REQUEST);
    } //use camera end

});

//initialize button
mFromGallery = (Button) findViewById(R.id.FromGallery);

//pick a photo
mFromGallery.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View arg0) {
        Intent photoPickerIntent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
        photoPickerIntent.setType("image/*");
        startActivityForResult(photoPickerIntent, SELECT_PHOTO);
    }
});//pick a photo end
}



//previewing Image
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
    //from the gallery
    case SELECT_PHOTO:
        if (requestCode == SELECT_PHOTO && resultCode == RESULT_OK && null!= data) {
            Uri selectedImage = data.getData();
            String[] filePathColumn = { MediaStore.Images.Media.DATA };

            Cursor cursor = getContentResolver().query(selectedImage,
                    filePathColumn, null, null, null);
            cursor.moveToFirst();

            int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
            String picturePath = cursor.getString(columnIndex);
            cursor.close();

            mImageView.setImageBitmap(BitmapFactory.decodeFile(picturePath));
        }
        break;
    //from the camera
    case CAMERA_REQUEST:
        if (requestCode == CAMERA_REQUEST && resultCode == RESULT_OK) {
            Bitmap photo = (Bitmap) data.getExtras().get("data");
            mImageView.setImageBitmap(photo);
        }
        break;
}
}//Preview Image End

reading your answer :

I already followed the code that you have before. I was able to upload the image to parse. but I dont know how to switch the drawable source to be my image from camera/gallery or imageview. – stanley santoso

I understand that your problem is not parsing your image ?

To try to answer your question :

I dont know how to switch the drawable source to be my image from camera/gallery or imageview.

1 - R.drawable.androidbegin seems to be your problem BUT the fact is that you already have your bitmap to parse in your code :

from gallery ->

mImageView.setImageBitmap(BitmapFactory.decodeFile(picturePath));

from camera ->

Bitmap photo = (Bitmap) data.getExtras().get("data");

2 - So I would suggest to declare a variable of type Bitmap at the beginning of your code

private Bitmap yourbitmap;

3 - then assign the bitmap for the gallery and the camera in your code and use it to parse it.

...
yourbitmap = BitmapFactory.decodeFile(picturePath);
...
yourbitmap = (Bitmap) data.getExtras().get("data");
...

4 - finally you can use your bitmap like so :

//    Bitmap bitmap = BitmapFactory.decodeResource(getResources(),
//                            R.drawable.androidbegin);
    // Convert it to byte
                    ByteArrayOutputStream stream = new ByteArrayOutputStream();
                    // Compress image to lower quality scale 1 - 100
                    yourbitmap.compress(Bitmap.CompressFormat.PNG, 100, stream);
                    byte[] image = stream.toByteArray();
           ...
