Can not move to external storage from internal storage in some devices

[npes87184]

Hi,

In htc u11, if I try to click ".." in the root of internal storage. It will show "Directory cannot be accessed". I guess it is because the root ("/") can not be read. This will lead to fail to move to external storage through internal storage.

I have worked for it to add a dropdown in dir_picture to direct the current directory to external sdcard without entering "/", look picture.

Any other good ideas?

Thanks.

Hey, That looks pretty awesome, but I can't see where you have put the spinner for this.

Hi, @Angads25

It is not spinner, it is pop-up menu.

My concern is it is too difficult to find from user.

Thanks.

you would need an icon to indicate that: https://www.tutorialspoint.com/android/images/spinner11.jpg

i guess it'a a spinner then :-) make it on the "folder" icon with that little triangle thingy

I think it will be helpful to add multiple roots in next version, what say?

[npes87184]

Sounds great, but how do you present the multiple roots? An option let user select between multiple roots if app define multiple roots?

btw, this commit shows how to do on the demo video. The method is not good enough, because of the targetApi 11.
