I'm a beginner, I tried to make this simple dice app, created 6 fragments and in each fragment included an imageview that would display the image for every turn of dice....After compiling the code, I am getting errors stating " java.lang.IllegalArgumentException: No view found for id 0x7f0800c4 (com.example.rollingdice:id/frag_three) for fragment Three{cff507d}" and the app is crashing adruptly.
