# We cannot implement Main in Java, as this would require to run
# dexmerger (to merge the Dex file produced from Smali code and the
# Dex file produced from Java code), which loops indefinitely when
# processing class 301108855, as this class implements itself. As
# a workaround, implement Main using Smali.
