android 反编译，逆向，注入LOG

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 <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;

    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;

    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

    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

    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
