ParseObject shop;
final int PHOTO_SELECTED = 1;
ParseFile file;
ParseFile photoFile;
final Context context = this;
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.openshop);  

    btn = (Button) findViewById(R.id.button1);
    Pic = (ImageView) findViewById(R.id.imageView1);
    final int PHOTO_SELECTED = 1;


    Pic.setOnClickListener(new View.OnClickListener() {
        public void onClick(View arg0) {

            Intent i = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);    
            startActivityForResult(i,PHOTO_SELECTED); 

        }
    });

} 

@Override
 protected void onActivityResult(int requestCode, int resultCode, Intent data) {
     super.onActivityResult(requestCode, resultCode, data);

     if (requestCode == PHOTO_SELECTED && 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]);
         final String picturePath = cursor.getString(columnIndex);
         cursor.close();

        final Bitmap bitmap = BitmapFactory.decodeFile(picturePath);
         Pic.setImageBitmap(bitmap);


         btn.setOnClickListener(new View.OnClickListener() {
            @SuppressLint("NewApi")
            public void onClick(View arg0) {
                 EditText name = (EditText) findViewById(R.id.sname);

                shop = new ParseObject("imagetest");

                 // Bitmap bitmap =BitmapFactory.decodeResource(getResources(), R.drawable.ic_launcher);

Bitmap bitmap = BitmapFactory.decodeResource(getResources(), Pic);

                    // Convert it to byte
                   ByteArrayOutputStream stream = new ByteArrayOutputStream();

                    // Compress image to lower quality scale 1 - 100
                    bitmap.compress(Bitmap.CompressFormat.PNG, 100, stream);
                    byte[] image = stream.toByteArray();
                    // Create the ParseFile
                    ParseFile file = new ParseFile(name.getText().toString()+".png", image);

                    // Upload the image into Parse Cloud
                    file.saveInBackground();


                    //Create
                    shop.put("name", name.getText().toString());
                    shop.put("UserOpen",ParseUser.getCurrentUser());
                    shop.put("Image", file);

                    shop.saveInBackground();


                    // Show a simple toast message
                    Toast.makeText(getApplicationContext(), "Created",
                            Toast.LENGTH_SHORT).show();
            }

         });

     }
}
