Android - Binary XML file line #10: Error inflating class <unknown>

Question

I am trying to go to another activity but the app crashes with these errors. I have 2 activity:

1. Acivity Chat
2. FriendProfileViewActivity

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.mycompany.newchatapp/com.mycompany.newchatapp.Activities.FriendProfileViewActivity}: android.view.InflateException: Binary XML file line #10: Binary XML file line #10: Error inflating class

Ok, I quickly ran your code and got THIS stack trace:

        at de.hdodenhof.circleimageview.CircleImageView.setScaleType(CircleImageView.java:134)

Removing scale type from friendProfilePic fixed the error.

To add to this, they do make a note of this in the documentation of the library: The ScaleType is always CENTER_CROP and you'll get an exception if you try to change it. This is (currently) by design as it's perfectly fine for profile images.

Please make sure to read your stacktraces carefully (if this was the issue) it will save you tons of grief :)
