Smali插桩打日志

一、smali目录下新建crack.smali，内容如下：

.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

.end method

.end method

.method public static J(J)V #打印出long类型的值

.locals 2

.prologue

const-string v0, "crack_log_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

二、使用方法（打印String）：

invoke-static {v1}, Lcrack;->log1(Ljava/lang/String;)V

三、有时日志太多，要写入文件分析：

.class public Lcrack2;

.super Ljava/lang/Object;

.source "crack2.java"

.method public static puts(Ljava/lang/String;)V

.end method

#使用方法：invoke-static {vx}, Lcrack2;->puts(Ljava/lang/String;)V
