反编译smali注入显示LOG的代码，备以后用：

.class public Lnet/iaround/connector/DebugClass;

.super Ljava/lang/Object;

.source "DebugClass.java"

# direct methods

.method public constructor ()V

.locals 0

.prologue

.line 5

调用方法：

invoke-static {p2}, Lnet/iaround/connector/DebugClass;->showLog(Ljava/lang/String;)V
