我以为肯定是 Toast (原谅 duangsuse 的 Android 开发水平和一年前没大长进) 但不是（我在 trap 了 Toast 类, 纯纯写作在反修改弹窗时没掉进去 😄）

(当然没人回答也可以，我也可以再猜其他类或者使用 layout inspect 应用)

检查的确有是使用 Toast 的, 但不确定

假设是随机决定是否弹出的话，说不定有这个功能会比较好：

让断点针对特定的类路径 regexp, 如果调用者的类路径 match 就正常中断/打印 call stack
否自动继续，只当没有这个断点

这次运气比较好，随便修改一个试试（可惜不是 smalidea, navi 目前能修改的类型很少）

刚才的 toast stacktrace:

      /Toast;:36

drakeet 应该使用了这个类美化 Toast

   -- android.widget.Toast.setView(Landroid/view/View;)V:0
   -- com.drakeet.purewriter.arm.setView(Landroid/view/View;)V:2

这个类之后使用了 Toast#setView

-- com.drakeet.purewriter.arm.show()V:0
// 之后它调用了
-- android.widget.Toast.show()V:0
// Toast#show 调用了
-- android.widget.Toast.getService()Landroid/app/INotificationManager;:0

暂且叫它 BeautifulToast (com.drakeet.purewriter.arm)

另外：

>> ## trace thread <25> RxSingleScheduler-1        (running suspended)
resume   -- android.content.pm.PackageInfo.<init>(Landroid/os/Parcel;Landroid/content/pm/PackageInfo$1;)V:0

-- snip --
   -- com.drakeet.purewriter.tn.Wwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwww(Landroid/content/Context;Ljava/lang/String;)Landroid/content/pm/Pac
      kageInfo;:6

我们看看 RxSingleScheduler-1
这是由 RxJava 管理的异步任务, 它可能要校验包签名

我会 untrap android.widget.Toast, 转而 trap com.drakeet.purewriter.arm
