I have written a java code in Android Studio to download and display an image from the internet on a button click. It shows errors
E/libc: Access denied finding property "ro.serialno"
and
Current dex file has more than one class in it. Calling RetransformClasses on this class might fail if no transformations are applied to it!
The log:
