在sdcard目录下面创建了一个文件提示下面的错误

android.system.ErrnoException: open failed: ENOENT (No such file or directory)

2 分析

错误代码是如下

String path = Environment.getExternalStorageDirectory().getAbsolutePath();try {File dir = new File(path + "/***/***/***/");if (!dir.exists()) {dir.mkdir();}File file = new File(path + "/***/***/***/", fileName);if (file.exists()) {return file;}if (file.createNewFile()) {return file;}} catch (Exception e) {return null;}return null;}

String path = Environment.getExternalStorageDirectory().getAbsolutePath();try {
