Android程序在第一个语句后崩溃

我有一个Android应用程序。我使用安卓工作室。在我添加与崩溃位置无关的代码之前，该应用程序正在运行。我在前几行上放置断点。当我正确启动调试器时，调试器在前两行停止，但在进入下一条语句之前崩溃。由于这部分代码没有改变，我不知道它为什么会崩溃。有人能推荐一些要找的东西吗

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_login);
    // Set up the login form.
    mEmailView = (AutoCompleteTextView) findViewById(R.id.email);
    populateAutoComplete();

以下是XML：

我将尝试使用以下代码更改代码，将EditText的任何实例封装到单个TextInputLayout中，因为您将获得以下stacktrace行：

android.view.InflateException:二进制XML文件行#73:我们已经有了一个EditText，只能有一个 在android.view.LayoutInflater.充气（LayoutInflater.java:551）

向我们显示您的日志粘贴您的XML文件和带有崩溃stracktrace的日志，以便我们为您提供帮助。错误消息是什么？您是否缺少onCreate方法末尾的结束括号？我们需要查看错误日志-如果我们不知道问题是什么，我们无法调试问题，并且“it crash”不是问题描述。我展示了逻辑。如何获取stacktrace？我将粘贴XML，但我看不出这有什么帮助。错误消息是标准崩溃消息。。。“不幸的是，Mynt已经停止”。顺便说一句，不要因为你帮不上忙就贬低别人。我没有要求任何人调试这个问题。我只是想问一个人如何看待这个问题（教育）。谢谢，我会试试的。正如我所说，我是Android编程新手，可能犯过愚蠢的错误。我为Nexus 7000编写了Cisco的收发器库，我是这些领域的专家，但在Java和XML方面真的很愚蠢。没有愚蠢，而是一条真正令人愉快的学习曲线，你过去所做的总结是synergy，不管怎样，如果你喜欢我，如果它有效，你也可以接受我的回答。希望它能工作，好运气坏了我的电脑，所以我不得不等几天tjem来修复它
