I have no difficulty saving to the internal SD card, but Android seems to not want to let me save to the external card. I remember reading that Android restricts access to the external card, but I see that other apps are writing to it, so I assume there is a way.

My Android version is 4.4.2. Looking at the directory "/mnt/" I see two SD cards available on my device: "sdcard" & "extSdCard." I am writing successfully to "/mnt/sdcard/," but get no result when trying to save data to "/mnt/extSdCard/," which is the one that can be inserted into the device.

I thought perhaps that the app needed to be signed and installed as it would from the Play Store, but that didn't work, either. Any ideas about whether it's possible to read and write the external card?

Thanks,

In Standalon application setting, did you check the right permission requests? ("write external storage")
Moreover, is it correct the name you use? Is it "/mnt/sdcard2"?

Yup check the standalone application settings dialogbox

I once wasted two hours because each time I opened the dialogbox my stupid assumption of what I thought was reality prevented me from seeing that I had in fact NOT ticked a particular box - DOH!

Eventually reality beat my assumption into pulp and I could see what had been in front of me all the time...

Thanks for both replies. Yes, I verified again that I have the "Write External Storage" box checked.

However, the names of the sd cards are somewhat confusing, depending on what I use to look at them with. For example, Astro File Manager reports "sdcard0" and "extSdCard." Then, when I use The Folders to list the directories under "/mnt" I get "sdcard" and "extSdCard." I am successfully writing to "sdcard" (not sdcard0), but it seems I can't write to "extSdCard." Nowhere do I see any other names for the external storage device.

I will try "sdCard2," though, and see what happens. It's frustrating, since I see that other apps have proprietary folders and files on the external card.
