Answer 1

once refer this tutorials it will be helpful to you http://khurramitdeveloper.blogspot.in/2013/07/capture-or-select-from-gallery-and-crop.html

after cropping you have to convert the image into base64 bit to upload into server. search in google there are many examples on web services in android

Answer 2

Probably your intent is returning null data try this.... for your selectImagefromGallery

Intent intent = new Intent(Intent.ACTION_PICK,
    android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(intent, 2);`

and in OnActivityResult

if (requestCode == 2) {
    Uri picUri = data.getData();
    System.out.println("picUri-----" +picUri);
    String path = getRealPathFromUri(getActivity(), picUri);
    System.out.println("PATH-----" +path);

to resolve imagePath use

public  String getRealPathFromUri(Context context, Uri contentUri) {
    Cursor cursor = null;
    try{
            String[] proj = { MediaStore.Images.Media.DATA };
            cursor = context.getContentResolver().query(contentUri, proj, null, null, null);
            int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
            cursor.moveToFirst();
            return cursor.getString(column_index);
        } 
        finally {
            if (cursor != null) {
                cursor.close();
            }
        }
}

To Upload add file part for your multipartentity

File uploadFile1 = new File(path);
multipart.addFilePart("photo1", uploadFile1);

Answer 3

intent = new Intent();
             intent = new   Intent(Intent.ACTION_PICK,android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
