我一直在为我的项目编写这个应用程序，我遇到了一个奇怪的情况，需要帮助，因为我找不到错误并且编译时没有错误。此外，该应用程序可以在安装了 Kitkat 4.4.2 的 Nexus 7 (2013) 平板电脑上运行，但不能在安装了 Cyanogenmod 11 M6 的三星 Galaxy S2 上运行。此外，它不适用于带有运行 Android 4.4.2 的原生 ROM 的 Galaxy S4。当我检查 logcat 上的错误时，我在 MainActiviy.java 文件的第 16 行收到错误。您可以在下面找到 logcat 日志、MainActivity.java 文件、activity_main.xml 文件和 android list 。我正在使用 Intellij Idea，但在 Android 开发工具上得到了类似的结果。非常感谢。

非常感谢您的帮助。
最佳答案
如果是 setContentView 的问题，很可能是您的布局文件中的 XML 错误，尽管这可能取决于您在平板电脑屏幕的文件夹中是否有单独的布局，例如布局-sw600dp。
关于java - Android MainActivity.java 错误(适用于平板电脑，但不适用于手机)，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/23982764/
