[Android Software/Hacking General [Developers Only]] M.A.K:
This package contains a few windows batch files to help you get UnifiedNLP working with (or without) Google Play Services on your phone. Extract it anywhere and run the batch files as needed. Everything required is included in the download but you will need root ADB capabilities. Learn more about ADB here:

http://wiki.lineageos.org/adb_fastboot_guide.html

For the record, I use this on Nougat. More specifically, LineageOS 14.1 so I can't say how it will work or what is necessary on other versions or roms.

Included Batch Files

To use these scripts your phone needs to be connected to your computer.

Install.bat - Install apks and addon.d updater script

Patch.bat - Patch framework-res.apk

DisableGoogle.bat - Disable Google location services and permissions

EnableGoogle.bat - Enable Google location services and permissions

Restore.bat - Delete apks, restore stock framework, enable services and permissions

GetDiff.bat - Create new patch file.

Background

UnifiedNlp is a network location provider that can be used instead of the Google network location service that's included in Google Play Services. The version used here is the GApps version that can be used along side Google Play Services.

Installing the Apps

Run Install.bat

UnifiedNLP has to be installed as a system app. This script installs it in /system/app along with some backends. It also installs an addon.d script so it will survive system updates if your rom supports it. Once installed, you can find the app in your app drawer. See the thread on XDA to help set it up.

Patching the Framework

Run Patch.bat

To use a location provider, it's package name has to be included in the "config_locationProviderPackageNames". This script patches framework-res.apk to include the UnifiedNLP package name. I've created a thread on the LOS subreddit asking for this to be included by default but until then we'll have to patch each update.

If patching fails run GetDiff.bat to create a new patch file:

When prompted, open arrays.patched.xml in your text editor (Notepad++ recommended)

Find 'config_locationProviderPackageNames' section

Add a new item 'org.microg.nlp'

Save and continue

Run Patch.bat again

Disabling Googles Location Service

Run DisableGoogle.bat

When you enable network location in settings you also enable Google's location service. There's no simple way to enable one without the other... Bit of a monopoly and totally wrong if you ask me, but that's the way it is. So we have to disable a couple of Google services to get UnifiedNLP working.

So now we should have UnifiedNLP working but we still have Google Play Services stalking us and constantly checking our location. This is what gives us all those NLP related wakelocks. To prevent this we just have to revoke coarse/fine location permissions for Google Play Services. DisableGoogle.bat also does this.

Disclaimer:

Needless to say, if you try this you do so at your own risk. I take no responsibility for anything.

It's always a good idea to make a full backup before doing anything like this to your phone.
