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”。

.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

2.将“log.smali”加入到工程的“smali”文件的根目录下。

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。
