安卓逆向之smali代码插桩打印日志操作步骤
1.将以下代码复制并保存到你本地并命名为"log.smali"，文件名可任意，后缀名必须为“smali”。
2.将“log.smali”加入到工程的“smali”文件的根目录下。.class public Lcrack;
.super Ljava/lang/Object;
.source "crack.java"
.method public static log1(Ljava/lang/String;)V #打印出info 1字符串
.locals 1
.prologue
const-string v0, "TAG"
invoke-static {v0, p0}, Landroid/util/Log;->d(Ljava/lang/String;Ljava/lang/String;)I
return-void
.end method
.method public static log2(Ljava/lang/String;)V #打印出info 2字符串
.locals 1
.prologue
const-string v0, "info 2"
invoke-static {v0, p0}, Landroid/util/Log;->d(Ljava/lang/String;Ljava/lang/String;)I
return-void
.end method
.method public static log3(Ljava/lang/String;)V #打印出info 3字符串
.locals 1
.prologue
const-string v0, "info 3"
invoke-static {v0, p0}, Landroid/util/Log;->d(Ljava/lang/String;Ljava/lang/String;)I
return-void
.end method
.method public static I(I)V #打印出int型值
.locals 2
.prologue
const-string v0, "info_int"
invoke-static {p0}, Ljava/lang/String;->valueOf(I)Ljava/lang/String;
move-result-object v1
invoke-static {v0, v1}, Landroid/util/Log;->d(Ljava/lang/String;Ljava/lang/String;)I
return-void
.end method
.method public static J(J)V #打印出long类型的值
.locals 2
.prologue
const-string v0, "info_long"
invoke-static {p0, p1}, Ljava/lang/String;->valueOf(J)Ljava/lang/String;
move-result-object v1
invoke-static {v0, v1}, Landroid/util/Log;->d(Ljava/lang/String;Ljava/lang/String;)I

return-void
.end method复制代码3.在你要打印变量的地方加上如下红框内语句，注：“V1”是你要打印的寄存器。
invoke-static {v1}, Lcrack;->log1(Ljava/lang/String;)V #V1是你想打印得值，需要替换你想打印得寄存器复制代码
