[G Pad 8.3 Android Development] annoyingduck:
This is currently only for Stock G-pad's running the current US firmware V50020d (not aosp or V50020b). US only at this time. OP will be updated if other firmwares become functional. These mods will enable full splitwindow support to your G-pad and allow you to selectively choose what apps are displayed in the splitwindow "menu". Also, please note that this is a collection of other users work combined together for the ultimate Mod!! I did not create anything here, I just put the pieces together and tested if it all worked (which it does 100%).

Prerequisites:

-You must be on firmware version V50020d

-You must be rooted

-You must have a custom recovery

-Root and recovery can be achieved using ioroot 25 and [MENTION=3210378]id10terror[/MENTION]'s recovery script both located here: http://xdaforums.com/showthread.php?t=2698267 . Please note that you must open the runme.bat script and manually change the firmware version from V50020b to V50020d in order for the recovery script to work. Then flash an updated TWRP from here: http://xdaforums.com/showthread.php?t=2551499

-Please keep questions about root and recovery out of this thread!!

Step 1: Get Splitwindow Working

-Download and flash the V500d splitwindow mod from [MENTION=3605892]hensonlf[/MENTION] located at the bottom of this post

-Boot device and using your preferred file manager add these 2 lines to the bottom of your build.prop:

ro.lge.capp_splitwindow=true

persist.splitwindow.support_all=true

-Save and reboot device

-Please read his thread here: http://xdaforums.com/lg-g-pad-83/themes-apps/split-window-g-pad-t2796066 for more detailed information, and don't forget to thank him for converting [MENTION=2941286]xdabbeb[/MENTION]'s mod to our device

-You are now running splitwindow on your tablet, but wait whats this mess?......every single app I have installed appears in the splitwindow menu in a random order!! Unacceptable!! Or if you want all apps to appear there, you can stop here.

Step 2: Enable Individual App Selection

-First we must disable all installed apps from appearing in splitwindow menu. Using your preferred file manager open your build.prop and change one line we added in step one here:

persist.splitwindow.support_all=true

to:

persist.splitwindow.support_all=false

-Save and reboot device - now your running the default LG value for splitwindow

-Download and install [MENTION=653239]XabdullahX[/MENTION]'s G-Flex splitwindow mod apk from his thread here (I am not providing the download, as he has a free and donate version - the donate version alphabetizes your apps): http://xdaforums.com/showthread.php?t=2707310

-Open app and grant it root permission

-When root is given, a list of all applications will be shown. Select the desired apps you want to appear in the menu when activated

-Click Apply

-Click Reboot to save (if you don't reboot from within the app, the settings will NOT stick - use the option he has provided)

-Done!! Enjoy your custom splitwindow without any crap you don't want shown
