[help] Trying to compile Eleven music app from LineageOS 14.1 - Android Q&A, Help & Troubleshooting

So currently I'm looking for a decent music app, I recently switched from Lineage14,1 to MIUI and I wanted at least a working music widget for my Nova Launcher and a cool music app, without those crappy ones full of advertisements from the play store (imho)
So I decided to trying to compile by myself the LOS14.1 music app, the apks I found are old and they force close every time.
I'm not a newbie when it comes to programming, but never touched android before, so, my OS is Manjaro Linux, using Android studio 3 from AUR. JRE8-openjdk, openjre etc.
The first thing I did, was downloading this ----> https://github.com/LineageOS/android_packages_apps_Eleven
Then, I imported the project using Android Studio.
Into the .project I've seen that is an eclipse ADT project, but I found that is deprecated.
After trying to solve some problems related to libraries with google (just posting the solutions I found, they were stupid problems) ---->
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
I ended up with this situation, 45 errors. And this is where I'm asking for help
What am I doing wrong? There seems to be that the program is using a non existent method from Canvas, called Release according to the documentation I found on the internet (not just that)
I'm also trying to reinstall eclipse ADT to compile this, I don't really know what to do
Also got a compilation log View attachment log.log
Or just the wrong java vm?

As far as I understand you are trying to build a system application source specifically taken from Lineage OS source tree as a standalone application.
It's possible but application is dependant to Lineage OS, not the Android SDK, so it's coded in a way that it can be compiled with it's dependencies in Lineage OS source.
You may either establish a build environment, download Lineage OS source, compile the package within, and try to install it, or try to resolve errors using Lineage OS sources in currently establish setup.
