我正在使用Mac上的离子2构建。

我有一个正在开发的应用程序。当我通过iOS XCode构建应用程序时，一切正常。
但是，当我尝试为Android构建它时，它会生成android-debug.apk文件，但是如果我尝试在模拟器（Android Studio）或我的Android手机上运行此文件，则似乎会加载但冻结。
我有3页。它加载了初始页面，我可以导航到第二页，但是一旦尝试导航到第三页，导航就会冻结。这仅发生在Android中。
结果，我认为我的第三页可能有问题导致导航中断。
如果有人有任何建议，或者可以建议我如何调试，我将感谢您的帮助。
这是第三页（构造函数中的初始警报未被调用）：

update
找到导致它崩溃的原因，但我不知道为什么。
构造函数：
alert('personUserService.ts constructor');
alert('personUserService.ts constructor firebase = '+firebase);
this.fireAuth = firebase.auth();
alert('personUserService.ts constructor this.fireAuth = '+this.fireAuth);
this.auth.subscribe((authState: FirebaseAuthState) => {
this.authState = authState;
});
第一个警报被调用，然后冻结。这意味着firebase对象正在导致其冻结。
这在iOS中起作用，因此不确定为什么它不在Android中。
firebase是node_modules/firebase/server-auth-node/文件夹中引用firebase.d.ts的名称空间。
我做了以下操作，我所有的问题都消失了：
1）ionic platform rm android2）ionic platform add android
