Updated Findings for "Directory Binding"

I guess nobody around here gives a damn that the storage on the Fire TV 2 is seriously gimped. With that said, here are my findings.

NOTE: THIS IS ALL ABOUT THE AFTV2

Directory Bind

https://play.google.com/store/apps/details?id=com.vanpit.android.directorybind

DOES NOT WORK

Folder Mount

https://play.google.com/store/apps/details?id=com.devasque.fmount

Works with some MAJOR limitations on the Fire TV side of the fence.

* First off, Folder Mount has a issue where you can't add your license for the full version onto your Fire TV. This is due to there being no proper Google Play solution. I've already sent an email to the developer so hopefully that person can help me around the issue.

* Secondly, with the free version of Folder Mount you can bind up to three games. Sadly you cant do the whole "Android" folder as well as "data" and "obb" :(

* You can however, bind a game's individual folder WITHIN "data" or "obb". The catch is, you need to have a "stub" (to use a term from the Wii hacking scene) folder in the original location.

For example

​

Let's use Asphalt 8. The meat of this game (BEFORE binding) is within this location: storage/emulated/0/Android/data/com/gameloft.android.AMAZ.GloftA8AS

the folder is 1.56 GB

- before binding, copy/paste this folder onto your desired location within your external USB hard drive.

- Go back to the original folder and erase everything out of it. By doing this, you are creating the "stub" that the Fire TV needs so it can believe that the files are still in the proper location

- head back to Folder Mount and create a binding, giving proper folder locations and...

- Start game and play.

If you check your internal storage within the Fire TV settings, you can clearly see that the space the game used to occupy has now been freed. This alone would be a perfect solution if it wasn't for one thing. We need a place to stick the original APK files. I tried mapping the ASEC folder. - needless to say, it was a f***ing mess! From what I can see, the ASEC folder is used primarily for apps that have been pushed to the SD card. The moment I tried binding that folder, most the apps pushed to SD was in a "not found" state for Fire OS. If someone could figure out where apps are "installed" to, on the Fire TV 2, I would be willing to test a bind.

Speaking of the SD cards Fire OS does this hocus pocus bulls**t with them. Bind the ASEC folder and you might get 2 or three SD removed apps to show but all others will be "not found". Try binding the entire SD card to a folder of your choice and Fire TV will get VERY "sometimey" with you. Sometimes you might have a card at the capacity of whatever card you have (in my case 4GB for testing). Sometimes it will show that you have a card inserted with NO space available. See what I mean? utter bull****! It's as if the Fire TV reads the physical capacity and locks things there.

One more note. The freggin Fire TV 2 is obsessed with stub folders. It makes things a pain in the ass when you're trying to figure out which folder is the "real" one. At one point I had stubs in three locations. Talk about an annoying patchwork system for file management. Ugh!

I'm done for now. Hopefully this will give someone a starting point for helping this community fix the biggest problem with this Android device. Seriously, the team behind the 4K Fire TV should be kicked in the rear end for this screw up! I get wanting to lock things to some degree but at least let me install as many games from YOUR store that I want and not limit me to 5 really good ones at a time.
