<p>I am not able to understand why the error is coming again and again?
I want to implement glide palette to have more effective UI.
I tried to invalidate caches/restart,rebuild project,clean project etc.
Please help me...stuck with this not able to debug further.Deadlines approaching..
Thanks in advance!</p>
