.end method
处理很简单，如果输入没有错误的话就调用 aue->g（）方法，然后退出对话框，我们 继续跟踪代码：
.method public static g(Landroid/content/Context;Ljava/lang/String;)V
.locals 3
sput-object p1, Laue;->u:Ljava/lang/String;
invoke-static   {p0}, Laue;->p(Landroid/content/Context;)Ljava/lang/String;  #☻调用 aue-p()方法☻
move-result-object v0  #保存“private_security_token”到 v0
invoke-static  {p0}, Landroid/preference/PreferenceManager;->getDefaultSharedPreferences(Landroid/co ntent/Context;)Landroid/content/SharedPreferences;
move-result-object v1
invoke-interface  {v1}, Landroid/content/SharedPreferences;->edit()Landroid/content/SharedPreferences$E
ditor; #获取一个编辑器
move-result-object v1
const-string v2, "private_password_token" #要写入保存的键值
invoke-static {v0, p1},
 
Lals;->c(Ljava/lang/String;Ljava/lang/String;)Ljava/lang/String;
#☻调用 als-c()方法进行加密
move-result-object v0
invoke-interface {v1, v2, v0}, Landroid/content/SharedPreferences$Editor;->putString(Ljava/lang/String;Ljava/l
ang/String;)Landroid/content/SharedPreferences$Editor; #调用编辑器的方法写入字
符串值
invoke-interface  {v1}, Landroid/content/SharedPreferences$Editor;->commit()Z#提交保存
return-void
.end method
这里将要保存的密码进行加密后保存，关键点就在于分析 aue-p()与 als-c()了。这里 我 再 跟下 去怕 没完没 了 ，说下 aue-p() 吧，它 的作 用是 写 入并保 存 “ private_security_token”， 而 als-c()方法 则 传入“ private_password_token”与 “private_security_token”进行 DES 加密，最后调用 als-a()方法进行位移与运算，最后 写入配置文件中。总结下代码的步骤为
