Why is my .putExtra not passing information?

I am creating an app similar to a notes app. I have an activity that is called AddEditUserActivity, and, as its name implies, it adds OR edits a user (the object that I created). When I click on a user on the RecyclerView, I am supposed to go to the AddEditUserActivity and see the 5 fields full with the info of the selected user with the title of the activity as "Edit User". When I create a new user, I am supposed to go to the same activity, but with the fields empty, and "Add User" as the title. Creating a user works fine, but when I try to edit it, the activity appears with "Add User" as a title and all the fields empty.
The strange thing is that I implemented some Toast messages like "User updated" and "User Created", and they show when they are supposed to. I think that the problem is in the MainActivity. When I click on a user, I putExtra to an Intent and then call startActivityForResult(EDIT_USER_REQUEST, intent). In the AddEditUserActivity, inside onCreate, I specified that if the intent has a specific extra (the id) then it means that I am updating the user. But it ignores that part. So I would really appreciate it if you could help me.
Here is my MainActivity:

#arget's comment is correct - you need to change this:
Intent intent = new Intent();
to this
Intent intent = getIntent();
or use it directly instead.
Another thing, why don't you make the user class implement Parcelable, and pass the user around instead of all its properties? It would make the code a cleaner.

This is one activity class of my android project and this activity depends on another utility class....which is mentioned below:
The statement Bitmap bitmap = ((BitmapDrawable)imageView.getDrawable()).getBitmap(); shows an error in "imageView" and the statement boolean result=userChosenTask.checkPermission(Crime.this); shows an error on "checkPermission"...but I don't understand why...because checkPermission is already defined in the utility class....

In your manifests.xml, you need to include permission:

Web service call from android using DataDroid library not returning data to activity

Below I've listed my activity code, call out to the web service, and the json parsing class I created to parse the web service results. I'm trying to pass a user object back to the activity to determine what they can/can't do, however, I'm not getting past the "after execute" log statement. onRequestFinished never gets called which is where I would have expected it to end up. Any help would be greatly appreciated as there doesn't seem to be much activity with DataDroid...
