[HOW-TO][5.0+] Make "Thomas was Alone" from Amazon APPStore work on 5.0+ topic

So if you bought, or got the app Thomas was Alone from the amazon appstore and tried to install it on your 5.0+ device you would get a rather nice(/s) screen saying "App not Installed", after wanting it to play on my dd (a 5.1.1 nexus 5)i decided to take a look on it, and found how to fix.
What you will need:
- PC
- Apktool: https://ibotpeaches.github.io/Apktool/
- Signapk: https://code.google.com/p/signapk/
- Thomas was alone apk http://www.amazon.com/Bossa-Studios-.../dp/B00LXFHI60
(you can dump it using root, downloading it via appstore, using a root file explorer, then going to /data/data/com.amazon.venezia/files/apks)
How to:
- Decompile the app using a cmd line on a folder where both apktool and signapk are, the command is "java -jar apktool.jar d <apk name>.apk" without quotes (since the apk is named as hash by the appstore, it will differ per device, also its without quotes and <>).
- Navigate to the folder with the same name as the apk, open AndroidManifest.xml and delete
android:installLocation="preferExternal" from the manifest tag(line 2)
before:
<manifest xmlns:android="http://schemas.android.com/apk/res/android" android:installLocation="preferExternal" package="com.bossastudios.twadroid">
after:
<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.bossastudios.twadroid">
- recompile it using "java -jar apktool.jar b <name of folder of decompiled apk>"
- sign it using "java -jar signapk.jar <key>.x509 or .pem key.pk8 <Name of the decompiled apk folder>\dist\<Name Of Decompiled Apk>.apk ThomasFixed.apk
- done, now you can install it via phone or via adb install ThomasFixed.apk
