    invoke-virtual {v0}, Landroid/widget/EditText;->getText()Landroid/text/Editable; //获取文本框内容

    move-result-object v0

    invoke-virtual {v0, v1}, Ljava/lang/String;->equals(Ljava/lang/Object;)Z//比较V0,V1是否相等 

    move-result v0 //结果给V0 

    if-eqz v0, :cond_0// V0等于0就跳转到 cond_0 (不相等) 删除此句即可爆破

    if-eqz v0, :cond_0 ，把这种删除了就可以了。

    .line 32
    new-instance v0, Landroid/app/AlertDialog$Builder;

    iget-object v1, p0, Lcom/example/crackme/MainActivity$1;->this$0:Lcom/example/crackme/MainActivity;

    invoke-direct {v0, v1}, Landroid/app/AlertDialog$Builder;-><init>(Landroid/content/Context;)V

    .line 33
    const-string v1, "\u63d0\u793a"
