反编译smali注射显示LOG该代码。以后使用：

.class public Lnet/iaround/connector/DebugClass;.super Ljava/lang/Object;.source "DebugClass.java"# direct methods.method public constructor <init>()V    .locals 0    .prologue    .line 5    invoke-direct {p0}, Ljava/lang/Object;-><init>()V    return-void.end method.method public static showLog(Ljava/lang/String;)V    .locals 5    .parameter "log"    .prologue    .line 9    new-instance v2, Ljava/lang/Exception;    invoke-direct {v2}, Ljava/lang/Exception;-><init>()V    invoke-virtual {v2}, Ljava/lang/Exception;->getStackTrace()[Ljava/lang/StackTraceElement;    move-result-object v2    const/4 v3, 0x1    aget-object v1, v2, v3    .line 10    .local v1, traceElement:Ljava/lang/StackTraceElement;    new-instance v2, Ljava/lang/StringBuilder;    invoke-virtual {v1}, Ljava/lang/StackTraceElement;->getClassName()Ljava/lang/String;    move-result-object v3    invoke-static {v3}, Ljava/lang/String;->valueOf(Ljava/lang/Object;)Ljava/lang/String;    move-result-object v3    invoke-direct {v2, v3}, Ljava/lang/StringBuilder;-><init>(Ljava/lang/String;)V    const-string v3, "."    invoke-virtual {v2, v3}, Ljava/lang/StringBuilder;->append(Ljava/lang/String;)Ljava/lang/StringBuilder;    move-result-object v2    invoke-virtual {v1}, Ljava/lang/StackTraceElement;->getMethodName()Ljava/lang/String;    move-result-object v3    invoke-virtual {v2, v3}, Ljava/lang/StringBuilder;->append(Ljava/lang/String;)Ljava/lang/StringBuilder;    move-result-object v2    const-string v3, ":\t"    invoke-virtual {v2, v3}, Ljava/lang/StringBuilder;->append(Ljava/lang/String;)Ljava/lang/StringBuilder;    move-result-object v2    invoke-virtual {v2}, Ljava/lang/StringBuilder;->toString()Ljava/lang/String;    move-result-object v0    .line 11    .local v0, pre:Ljava/lang/String;    const-string v2, "yangjianchao"    new-instance v3, Ljava/lang/StringBuilder;    invoke-static {v0}, Ljava/lang/String;->valueOf(Ljava/lang/Object;)Ljava/lang/String;    move-result-object v4    invoke-direct {v3, v4}, Ljava/lang/StringBuilder;-><init>(Ljava/lang/String;)V    invoke-virtual {v3, p0}, Ljava/lang/StringBuilder;->append(Ljava/lang/String;)Ljava/lang/StringBuilder;    move-result-object v3    invoke-virtual {v3}, Ljava/lang/StringBuilder;->toString()Ljava/lang/String;    move-result-object v3    invoke-static {v2, v3}, Landroid/util/Log;->e(Ljava/lang/String;Ljava/lang/String;)I    .line 12    return-void.end method# virtual methods.method public o()Ljava/lang/String;    .locals 1    .prologue    .line 15    const-string v0, "888888888888888"    .line 21    .local v0, rtn:Ljava/lang/String;    return-object v0.end method

调用方法：

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