我的应用程序在平板电脑上启动时手机崩溃时运行良好。它在我运行 2.3.7 的手机和我姐姐运行 4.0.3 的手机上运行良好。但它在我运行 4.0.4 的 10.1" 平板电脑上崩溃了。我在运行 4.2 的 Nexus 7 AVD 上尝试过它，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？

尝试将所有 xml 文件放在layout文件夹中，如果它已经存在，则无需将其从其他文件夹中删除。

如果 xml 文件位于类似文件夹中，layout-sw600dp那么如果屏幕宽度小于 600dp，设备将无法加载指定的 xml 文件。这只是您的示例，可能会有所不同

我已经阅读了您的日志，查找目录时存在错误，您是否使用某种目录方法从特定位置检索文件，平板电脑具有内部存储而不是 sd 卡可能是问题所在。

但是，如果您发布代码，我会更好地理解。
