Help with Android Development - Android Q&A, Help & Troubleshooting

Hi, I am new here on xda, and this is my first thread so I wish that I am on the right section of the forum for this question. If not please explain me where else to move it. Thanks in advance.
So, I don't work as an engineer or somethink affiliated with this matter, moreover I have degrees in completely different fields from IT. But, the software development is a big hobby of mine from some years.
As for now I can program in C+, Python, little of Java, and I am spending these months of quarantine studying cybersecurity and system administration (lots of linux commands, trying dozens of linux distribution/BSD, trying some pentesting on a Metaesploitable I set up on a VM, etc...).
And here comes my problem which I address to you: I want now to start develop on android, trying to descover things etc..., one example above others I have an LG V30 with android Pie 9.0 for which there is no root procedure yet unless you downgrade to android Oreo, so how do I work on my smartphone directories? I do I develop on a Android phone? and what skills are required of me, in terms of programming languages, cybersecurity knowledge etc?
I thank in advance who will take their time to help me.

Thank you. Really helpful, but I need something more specific, this is for building apk, I want to admin my phone directories, like gaining root privilege (not with prebuild app and procedure) and modify things like the firmware.

Typically Android users steer / manage Android by means of ADB ( read: Android Debug Bridge ) . Hence become familiar with ADB.

Thank you so much, that's was exactly the insight I was looking for .
Is there anywhere where I can start with ADB? Like a section here on XDA, Github or somewhere else? Youtuve Video guide (serious and professional ones)?

I think you're smart enough to do the search yourself.
I'm not gonna waste my time: sorry for this.

Hey guys new developer needing help

Hey guys uhm i am a programmer needing to know how the android OS works as a whole im proficient in Java C++ with a little bit of PHP and Python. Now ive been wanting to get into android development for roms and custom mods but i do not have a good knowledge on how android works. i mean i know basic things like ADB, Build.prop, the linux command lines for terminal, linux kernals, and other basic things. But if you point out a file or piece of android files/folders i would probably not know what it does or what it is used for. and i was wanting to know if there is a guide on all this. or a book cause i have looked around an all i see is how to develop apps and not develop for the source code. any help would be greatly appreciated and thats all

[help]

I hope I'm not posting this in the wrong forum, but i'm posting here because i think i am in the right place.. If not mods please move this to appropriate forum..
So I'm on the nexus s 4g and i'm feeling like i'm ready to get into porting and then development.. I really just need help understanding eclipse and how to port in general.. I know eclipse is great for developement and I just installed the adt and the sdks through eclipse and I need to know how to set this up so I can run a logcat through adb so I can see why my port isn't fully booting.. I'm stuck at the boot animation.. I've tried reading some guides but because i'm still a noob i feel like there's always something i'm missing.. I was hoping someone here would be so kind as to help run me through on getting this set up and helping me understand the fundementals..
there are many that know more than me, but i can try to help a little bit...
first off, im going to assume you are porting roms, not apps, because of how you have things worded i was a bit confused at first.
now, eclipse is an amazing IDE, but when it comes to porting android roms from device to device its not going to be much (if any at all) help to you. eclipse is great for application development, and building a full, ready to install android package (apk) for pushing to the market or side-loaded. (installed on data partition)
there dont tend to be many guides or strait line ways do do things. it all comes out of experience and good problem solving skills. learn to read your logcats, understand what they are saying. you will get it!
im more of a source built kind-of-guy, and never did any porting of pre-compiled roms. but i know http://freeyourandroid.com/ is a great resource for getting started with just that.
please also think about looking into the android build system, its complicated, but you will get it eventually, and it will teach you how a rom really works, and is really built, and it gives you complete control to do anything you want.
hope this was a little help.

the only reason i was setting up eclipse for this was because it was to my understanding it had the tools needed to get adb to produce a logcat, i've delt with apps before.. I made myself a lil launcher for miui and a couple others, but i just have no idea on how to do anything with adb and gettings log cats.. I do appreciate your response and i will take a look at that website.

i only know gw basic programming but i know its not useful as android developement requires c++
Anything without programming ?
i am learning c++ but even if I learned where can I start to port
You can always follow tutorials .. it takes long time for u than those with programming knowledge... There is everthing in net what u need to know..... I learned web designing n photoshopping myself without any multimedia or programming knowlege( i'm in medical field)... i always follow specific tutorial for evertime i need to do something.. i had the opportunity to be an admin with full power of a forum which still i'm, and access to do all work for it where i did all work n never given any work for proffessionals..
So best way is actually start doing it rather than trying to learn n then do it... trial n error method is best way for those who dont have any knowledge or experience... Now i'm thinking of touching my hand in Android let me see

You have to dig into it... As google's tutorials say- You start with some .apk in the category of ur interest by modifying n learning to develope to ur ideas.... Dont try first of all to develope an app from scratch.. it meant for Those who have indepth knowledge....

Try this out:

A few simple tutorials should never steer you wrong.
Try a few!
I recommend going to Lynda[dot]com, you may find there all you need to learn about android and anything related to it

How do rooting apps work?

I know that rooting basically gives you SU access, I am learning Java Programming and would like to be a part of the community and help to develop rooting methods, but I am still a noob with much to learn, what exactly does source code for a root exploit do? Is there somewhere I can go through it line-by-line, perhaps with comments in regards to what each section does?
Or is there some way to learn this? I want to learn to develop ROMs, themes and rooting methods but I dont know where to begin other than obviously learning Java programming...
Thanks much! and if I posted this to wrong section please let me know!
anyone?

Starting my journey in Android Development, need your help

Hello guys,

Where to start ? A good course to recommend ?

You need to be a skilled JAVA programmer: Android apps are programmed in JAVA.
