无法创建 nomedia 文件
通过Android SDK和AVD Manager我创建了一个android3.0版本的AVD，大小选项为1024MiB。在我的应用程序类中，我要求创建一个目录，以便可以缓存图像。但我在那里遇到错误，因为
09-07 15:32:31.253: ERROR/AndroidRuntime(380): Caused by: java.lang.IllegalStateException: Unable to create nomedia file.
我的代码是：
File baseDirectory = new File(Environment.getExternalStorageDirectory(), "myapp");
File storageDirectory = new File(baseDirectory, "imagecache");
File nomediaFile = new File(storageDirectory, NOMEDIA);
nomediaFile.createNewFile();
错误出现在第四行。有人可以帮我吗？我是蜂窝新手。提前致谢。

正如其他人所建议的，您应该使用
mkdirs()来确保您的目录路径在那里。您还需要WRITE_EXTERNAL_STORAGE权限。As others have suggested, you should have
mkdirs()to ensure your directory path is there. You also need theWRITE_EXTERNAL_STORAGEpermission.
