When an app is installed and has access to your SD card, can that app access anything on the SD card? Photos, etc.
I am not a developer, but as I understand it the SD cards are a FAT file system which does not allow for file system permissions. This is needed because they are removable and the data needs to be accessible by other apps once inserted into another device. Does this make any data stored on the SD card readable by potentially malicious apps that have access to or are installed on the SD card?

So, the filename for the real sd card is sd-ext, while the internal memory is sdcard, is there any way to correct this and allow the installation of apps to the real sd card?
Device: Moto E 2015
Android: 5.0.2
Coming from android 4.0 I could manage files on my external SD card using Windows Explorer, AirDroid, or any 3rd party file manager.
Now that I'm using 5.0.2 I cannot manage files on the external SD card using any of those methods. The SD card has over 14 gigs free. The card is formatted and works as Google pushed over my photos and music from the internal SD card fine.
Another problem is I can't move any apps to the SD card. With android 4.0 I could push an app like iBird Pro to the external SD card. Now when I try to push that app to the external SD card it claims there is not enough space. Android storage shows there is over 14 gb free and iBird Pro is under 1 gb.
It would appear that 5.0.2 is a total wreck when trying to make use of the external sd card. *sigh* I hear rumors that M may fix this... if the Moto E 2015 happens to get that update.
You can transfer media to your SD, transfer some apps to SD (if they allow it) But SD write permissions have been a PIA since 4.4.X, so hopefully M does sort it all out.

So basically useless right now. I manage my own media content in a structure I like. Sad. Hopefully M will fix this mess.
Still trying to write to the external sd card. Latest developments.
Moto E 2015
Android 5.0.2
Windows 8.1
Trying to transfer files or create folders on the external SD card in my Moto E 2nd Gen. causes the following error:
"The device has either stopped responding or has been disconnected."
What I can do:
Delete folders
Read
Copy from sd card to Windows
What throws the error:
Creating a folder
Copying files to the sd card
On the device itself I cannot get any file manager to write to the external sd card. Apps that try to setup write permissions to the sd card fail. Android itself was able to move photos and music to the sd card when I inserted it into the phone. If I try to move any app to the SD card it says there is not enough space. It has 14gb free.
I finally tried using another computer. The other system is Windows 7 and I was able to created folders and copy files to the external sd card in the phone.
Back to my main system (Windows 8.1) I used USBDeview and cleared ALL usb drivers. Reconnected keyboard and mouse. Then plugged in the phone... same behavior. I have also tried installing Motorola's driver suite and have the same result. I have tried various USB ports on my motherboard both USB 2 and 3.
I'm at loss of what to try next, besides a blunt object to both devices repeatedly.
And I may have just fixed the problem of moving apps to the external SD card.
I erased the card while it was still in the phone. I did this the first time I put it in. I choose NOT to have Android copy over music and photos. Now I can move apps over to the SD card.
However, when trying to create a folder on the SD card from Windows Explorer it just hangs: SD card (Not Responding). It does show "New Folder" after terminating file explorer and looking at the SD card again. And now.... I can rename the folder, create folders, and copy files to the SD card... wtf.
Perhaps the SD card is bad, it is incredibility inconsistent.

I have a 2nd Gen Moto G with Android 5.0.2 and I'm trying to move apps to the SD card as well. I'm a bit confused as to what steps you followed. Are you saying that BECAUSE you erased the SD card and chose not to have Android copy music and photos that you can now move apps to the card? Or are you saying that since reversing your decision and allowing Android to copy over music and photos (and possibly reformatting your erased card?) that you can now move apps to the card? And can you transfer any apps or only certain apps? Are you doing this on your phone or on your computer?
I can transfer certain apps to my SD card on the phone. And using the computer and Windows Explorer I can create a new folder on the SD card. I'm just not sure what steps to take next to transfer the apps to the card, or what impact there might be on data or functionality.
I need to install my app on sd card with data and launcher, so that it can be used on any another android phone/Tab.
How do I achieve this?
I willing pay for an app/ script that will allow me do this or information on how to do it.
You will need to partition external sdcard creating additional ext partition for apps and regular fat partition for media.
Then use link2sd to move apps from internal memory to ext partition.

what you are asking I dont think, in fact I'm sure cannot be done as the actual phone/tab needs to be the 'thing' that installs the app, ie knows it has the app installed. THEN the actual app and data can be moved to sd card. Kind of like a marker, you could install an app on phone/tab A and move to sd card, then put the card into tab/phone B and install it there and move to sd then, I think, the same card can be exchanged between the 2 devices.
I was attempting to root my Alcatel 9007t tablet, so I could move apps to my SD card, unsuccessfully.
So I ended up following some instructions and ended up emulating an SD card on my internal, or something or the other
It renamed my actual SD card to something else
So now, I have rooted my phone, I believe, but using link2sd card I can now move my apps, but I get an error on a certain few apps.
I can't link the data, or what have you, to the SD card, and I think its because of this emulated SD storage
Regardless, I would like to remove the emulated SD storage, and rename my SD card to something normal.
Getting to root this thing was difficult, so I would not want to start this whole thing over.
Or if I could get link2sd to link my data to my SD card , that would be excellent.
I am moderate noob so pls hlp
Footnote: no I cannot link to SD thru my storage settings, maybe is there somehow I can do that. I just want to link or move app data to SD card. This is from a downloaded apk that is making kit difficult. The app seemed to install to SD card, but the data is on the emulated SD on the internal
Halp
You will have issues as apps are not made to be on the sdcard and some apps even block the option.

OK but my tablet is rooted now and I can do it mostly with no problem.
I just want to rename and unemulate false SD card on internal and get it back to normal
Is there any apps that allows us to play Game data/obb on external sd card? i know some apps like Link2sd,foldermount,app2sd. but they seemed to be not working on recent android version. the only option i have now is to format external sd card as internal storage but it's kinda useless cause it cant move game data to external sd card,only the apk file. i also have option to 'Migrate' to external sd card and this one will allow me to move game data/obb to external sd card but my internal sd card will be useless and unaccessible. i have 64b internal storage and i want to keep my apps on internal storage for performance purposes. i just want to put and play some of my game data to external sd card.

Check in Xposed installer. they might have some modules. I'm not so sure. But it should be worth a try
