我是Android开发的新手，我还在学习。我正在尝试创建一个基本的应用程序来显示到达的公共汽车路线时间（带有公交路线的导航抽屉的简单文本）。
我正在使用Android Studio导航抽屉模板。
适用于我的HTC Desire（Bravo）API 10，但拒绝使用华为Media Pad 7 Lite（API 11）。
这是logcat

我不知道如何正确检测错误在哪一行，我在几个地方读到了我应该寻找“引起”的行，但它并没有给我提供很多信息或者我不知道如何正确识别它们。
任何帮助都会受到赞赏，我尝试在所有地方搜索，但我找不到任何与我的问题有关的内容，也没有解释为什么会发生这种情况。
在HTC Desire（API 10）上，logcat没有显示错误。
如果您需要任何源代码，请告诉我，我不知道要粘贴什么，我仍然想要了解所有内容并了解实际情况。

编辑：评论以下部分使其适用于API 11+，确认这是问题所在。
