smalidea官网其实有提到,IDEA的版本必须14.1或以上,才能单步调试,否则是按照行号(.line)执行而非smali指令。
原文:
Single-instruction stepping is only supported in IDEA 14.1 and greater, and any future version of Android Studio based on IDEA 14.1 or greater. In earlier versions, attempting to single step will step to the next .line directive, instead of stepping to the next instruction.
