i think you are using appcompatactivity(extending from appCompatActivity). if yes. then either changeit to activity or add library to give backward compatibility for 4.4 — Abdullah Raza, Nov 07 '17 at 04:47

do this , do a clean/rebuild project then test , java.lang.VerifyError happens if there is a compiling error in generating byte code.

Make sure all your library dependencies defined in gradle must be of same version.
