android sinovoice写权限,Android 在系统中建立文件夹（车机）

//获取外部存储路径

String storage = Environment.getExternalStorageDirectory().getPath() + "/smallIcon2";

File dirFile = new File(storage);

Log.d("dirFile", "" + dirFile);

if (!dirFile.exists()) {

boolean mkdirs = dirFile.mkdirs();

if (!mkdirs) {

Log.e("TAG", "文件夹创建失败");

} else {

Log.e("TAG", "文件夹创建成功");

}

}

该storage即/storage/emulated/0位置。

在xshell中查看emulated下其实无0这个文件夹，原因是该地址是一个链接地址如

root@sabresd_6dq:/storage/emulated # ls

legacy

root@sabresd_6dq:/storage/emulated # ls -al

lrwxrwxrwx root root 2015-12-31 18:00 legacy -> /mnt/shell/emulated/0

root@sabresd_6dq:/storage/emulated # ls -al /mnt/shell/emulated/0

drwxrwx--x root sdcard_r 2019-12-31 10:00 Android
