2 days ago XML Layout ran perfectly, now (with no structural change) it gives me errors?

Question

Two days ago, I posted the following question. While there were issues, it still ran - I could test the code on my phone still. However, with no major changes to the code (and definitely no structural changes), the program will refuse to run when I get to my Second Activity and crashes.

Luckily, I had posted all of my XML code for that Activity in the linked question.

Error (Warnings actually)

Element fragment is not allowed here
Element ImageView is not allowed here

How can this be?? This was working code that I ran on my phone, and now it is giving me a long list of error messages and I cannot run my second Activity, but I can run my first Activity.

Detail

This inspection highlights unallowed XML tags in Android resource files and AndroidManifest.xml

Extra Information

I updated my IDE from Android Studio 1.3 preview 4 to preview 5 since posting the linked question

One very obvious difference is the non-working xml contains the opening declaration line, a requirement of [well-formed xml](http://www.w3.org/TR/REC-xml/#dt-valid). Not at all familiar with android development but browsers even mobile ones can render xml files differently even ones not well-formed. — Parfait, Jun 20 '15 at 00:59
`` This?? This line is in all my layout resource files. All of them. I must not have copied that into the "working" xml — Christopher Rucinski, Jun 20 '15 at 01:03
Try Inavlidate caches and Restart Android Studio by FIle > Invalidate Caches and restart — Rajesh Batth, Jun 20 '15 at 04:51
Invalidate Caches / Restart - did not work. I will post onCreateView — Christopher Rucinski, Jun 20 '15 at 05:00
This is the cause of your inflation error: 'Bad class: class java.util.GregorianCalendar'. Why this bad class error suddenly occurs, I don't know. Try googling that. — Streets Of Boston, Jun 20 '15 at 05:17

ummm...the issue was a copy-paste issue. I should have had the correct XML `R.layout.fragment_movie_detail` ㅡㅡ — Christopher Rucinski, Jun 20 '15 at 05:57
I think you should check **atcom.udacity.rucinskic.spotify_streamer.SecondaryActivity.onCreate(SecondaryActivity.java:21)** — Iamat8, Jun 20 '15 at 06:34

I had the same problem. Try exchanging the ImageView to an android.support.v7.widget.AppCompatImageView. It solved the problem for me!

Did you have an error before doing this with my code? – Christopher Rucinski Jun 20 '15 at 16:43
i had allready set my project to new build tools before i add yr code – ceph3us Jun 20 '15 at 17:13

No I didn't. The error and warnings are separate issues. This question was on the XML warnings. I fixed the errors, not the warnings. Your fixes did not work. – Christopher Rucinski Jun 26 '15 at 00:42
