Binary string XML file # 0: bloating error on class <unknown>

Question

I have an error while starting the quiz. Something like this (with open gaming activity). My application stopped and I got a Binary XML file error in line No. 0. This is a bit strange because I did not see such a problem with line 0, so I need your help, everyone. Thanks!

What is the problem?

Answer 1

The problem is with the library itself, if you attrs.xml :

 <attr name="buttonColor" format="color" /> 

As you can see, buttonColor accepts only the color value, NOT , and the view tries to convert the reference value that you pass in xml to color, and it throws an exception. Therefore, you can only use the color for this attribute (for example: # 000000) or expand the project and modify attrs.xml as follows:

 <attr name="buttonColor" format="color|reference" /> 

Answer 2

Try removing the cornerRadius property, which may be due to a problem with the library.

 fbutton:cornerRadius="10dp" 

Remove all buttons and work well

Answer 3

Not sure what specifically relates to your problem, but I came across something similar, and my problem was that one of the layout files still used the support library after switching to AndroidX. Found that reading the entire stack trace.
