This is a very simple guide on how to install and Play:
HEARTHSTONE®, Blizzard Entertainment’s award-winning collectable card game
The only thing to do is start with a clean install following this guide:
HP TOUCHPAD Optimize for Android with Swap Partition Flash Files
The following screenshots were taken using Android 9 Pie Dirty Unicorns V13.0-20190328-1316-RC.
Install the ROM exactly as posted
Use Open Gapps Pico, the basic to get the Play Store and install the Game.
Enable Developers mode and take a look at the running services:
Wait until the free memory becomes available above 400 MB, that means that most of Android services have finished their process.
Run the App
After the App is install it will required to download over 1 GB of data, make sure your WiFi signal is good and fast!
The finished installation size:
All the screenshots were taken from installation and then the game was played during days, ( I am not a gamer very bad at it )
After you have play the Game for hours and you are done, close it and take a look again at the Free available memory.
It will show over 500 MB, more than when the game started of 400 MB, that shows that most of Android OS was placed on the swap partition to make more RAM to run the App. The System is stable and no process gets Kill or Reboots, never turn off the Tablet, leave it charging when not in use, with the screen off
More Apps can be install in the Tablet, but go easy and install one at a time and monitor the Free Memory in Running Services. If the App stays active in the background using memory it will prevent from running the Game. The Free memory must be close to 400 MB.
I am not the creator of any ROM, Recovery or Kernel mentioned or used. All credits goes to the developers than have worked and provided the best software there is for our Tablet and there are way too many to mentioned, but everyone know who they are! Thanks a lot to all of YOU (Developers for the HP Touchpad)!
Special Thanks @flintman for all his work creating TWRP Recovery and the many customs ROMs, also @shumash for creating the Skz kernel providing higher CPU and GPU frequencies
