Create Folder in usb android non root device?
问题
无法在Android 5.0以上的非Root设备中通过此方法在USB存储上创建文件夹或文件。
File dest = new File("storage/usbotg/usbname/foldername");
dest.mkdir();
我将成功地使用以下NDK C代码在内部存储中创建文件或文件夹。
FILE* fp = fopen("/sdcard/sample.txt", "w+");
但是无法通过应用程序在USB存储中创建。
FILE* fp = fopen("/storage/2F5A-E677/sample.txt", "w+");
