我的应用在平板电脑启动时手机崩溃运行良好。它在我的手机上运行良好，运行2.3.7，我姐姐的手机运行4.0.3。但它在我的10.1英寸平板电脑上运行4.0.4崩溃。我在运行4.2的Nexus 7 AVD上尝试了它，它也在那里崩溃。
这是日志

请帮助这是非常令人沮丧的。它曾经在平板电脑上运行良好。它可能与布局有关吗？
答案 0 :(得分：2)
尝试将所有xml文件放在layout文件夹中，如果已存在，则无需将其从其他文件夹中删除。
如果xml文件位于layout-sw600dp这样的文件夹中，那么如果屏幕宽度小于600dp，设备将无法加载指定的xml文件。这只是你的情况下可能不同的例子

我已经阅读了你的日志，找到目录有一个错误，你有没有使用一些目录方法，从特定位置检索文件，平板电脑有内部存储而不是SD卡可能有问题。
但是如果你发布代码，我可以更好地理解。
