2 days ago XML Layout works fine, now (no structural changes) is it giving me errors?

I posted the following question two days ago . While there were problems, it still worked - I could check the code on my phone. However, without any major changes to the code (and certainly no structural changes), the program will refuse to run when I get to my second activity and crashes.

Luckily, I posted all my XML for this activity in a related question.

Error (actually warnings)

  • Element fragment is not allowed here

  • Element ImageView is not allowed here

How can it be? ... This was working code that I ran on my phone and now it gives me a long list of error messages and I cannot start my second activity, but I can start my first activity.

Detail

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

Additional Information

  • I updated my IDE from Android Studio 1.3 preview 4

    to preview 5

    after posting the linked question

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

TRY:

  • SET NEW BUILD TOOLS IN GRADLE IN APP MODULE
  • INSTALL NEW PLUGIN IN PROJECT
  • CHECK SUPPORT LIBRARIES DEPENDENCE
  • INVALIDATE CACHE

project enter image description here
