逆向教程->在APP中添加提示框

在启动页oncreate中添加：


    invoke-virtual {p0, v0}, L当前页面地址;->setContentView(I)V
#v0是当前页面在public中的数值，p0无所谓，L路径要与当前java路径保持一致


    .line 16
    invoke-virtual {p0}, L当前页面地址;->Dialog()V
#p0不管，L路径要与当前java路径保持一致


在当前页面（启动页）下添加虚函数（# virtual methods）：
.method public Dialog()V
    .locals 3


    .prologue
    .line 20
    new-instance v0, Landroid/app/AlertDialog$Builder;


    #v0=(UninitRef,Landroid/app/AlertDialog$Builder;);
    invoke-direct {v0, p0}, Landroid/app/AlertDialog$Builder;-><init>(Landroid/content/Context;)V


    .line 21
    .local v0, "builder":Landroid/app/AlertDialog$Builder;
    #v0=(Reference,Landroid/app/AlertDialog$Builder;);
    const/4 v1, 0x0


    #v1=(Null);
    invoke-virtual {v0, v1}, Landroid/app/AlertDialog$Builder;->setIcon(Landroid/graphics/drawable/Drawable;)Landroid/app/AlertDialog$Builder;


    .line 22
    const-string v1, "提示框标题，记得转U码"


    #v1=(Reference,Ljava/lang/String;);
    invoke-virtual {v0, v1}, Landroid/app/AlertDialog$Builder;->setTitle(Ljava/lang/CharSequence;)Landroid/app/AlertDialog$Builder;


    .line 23
    const-string v1, "提示内容，记得转U码"


    invoke-virtual {v0, v1}, Landroid/app/AlertDialog$Builder;->setMessage(Ljava/lang/CharSequence;)Landroid/app/AlertDialog$Builder;


    .line 24
    const-string v1, "确定按钮内容，记得转U码"


    new-instance v2, L当前页面地址$尾数;
#L路径要与当前java路径保持一致


    invoke-direct {v2, p0}, L当前页面地址$尾数;-><init>(L当前页面地址;)V
#L路径要与当前java路径保持一致


    #v2=(Reference,L当前页面地址$尾数;);
    invoke-virtual {v0, v1, v2}, Landroid/app/AlertDialog$Builder;->setPositiveButton(Ljava/lang/CharSequence;Landroid/content/DialogInterface$OnClickListener;)Landroid/app/AlertDialog$Builder;


    .line 33
    invoke-virtual {v0}, Landroid/app/AlertDialog$Builder;->create()Landroid/app/AlertDialog;


    move-result-object v1


    invoke-virtual {v1}, Landroid/app/AlertDialog;->show()V


    .line 34
    return-void
.end method




插入一个新文件在同目录下：
当前页面地址$尾数.smali（例：MainActivity$1.smali）

#如果出现重名，则递进

该文件内容如下：

.class L当前页面地址$尾数;
.super Ljava/lang/Object;
.source "MainActivity.java"


# interfaces
.implements Landroid/content/DialogInterface$OnClickListener;




# annotations
.annotation system Ldalvik/annotation/EnclosingMethod;
    value = L当前页面地址;->Dialog()V
.end annotation


.annotation system Ldalvik/annotation/InnerClass;
    accessFlags = 0x0
    name = null
.end annotation




# instance fields
.field final synthetic this$0:L当前页面地址;




# direct methods
.method constructor <init>(L当前页面地址;)V
    .locals 0


    .prologue
    .line 1
    iput-object p1, p0, L当前页面地址$尾数;->this$0:L当前页面地址;


    .line 24
    invoke-direct {p0}, Ljava/lang/Object;-><init>()V


    #p0=(Reference,L当前页面地址$尾数;);
    return-void
.end method




# virtual methods
.method public onClick(Landroid/content/DialogInterface;I)V
    .locals 0
    .param p1, "dialog"    # Landroid/content/DialogInterface;
    .param p2, "which"    # I


    .prologue
    .line 29
    invoke-interface {p1}, Landroid/content/DialogInterface;->dismiss()V


    .line 30
    return-void
.end method

小结：从APP中将这个提示框一步一步剥离开来。
