I have created a profile creation page where users fills out a variety of information that gets recorded into parse. In this activity page a list of information from parse will be retrieved like Age, Name, Headline, and picture of many users in list (excluding current user). I have, however, experienced issues in retrieving images. Below is the error I have received from logcat:

startActivity(intent);
} else {
Toast.makeText(getActivity().getApplicationContext(),
"Error finding that user",
Toast.LENGTH_SHORT).show();
}
}
});
}
}
In particular, I think the error derives from the following line:
alProfilePicture.add((Images) userList.get(i).get("ProfilePicture"));
Thanks in advance, and all the best. Update
issues encounter
ParseQuery<ParseObject> query = ParseQuery.getQuery("User");
query.getFirstInBackground(new GetCallback<ParseObject>() {

file.getDataInBackground(new GetDataCallback() {

if (e == null) {

//use this bitmap as you want
