How to start writing an Android app?

Question

Java

Good day.
Need help learning
There is a personal understanding of the structure of the application. It should do
1. it's a Task List
2. have reminders and alarms
3. be able to schedule work shifts (2/2 or scheduled) night day full shift or not and time by
shift 4. display work shifts on the calendar in a different color
5. the ability to accept user data to work (answers to questions) with them and keep statistics
6. play music and display text (simultaneously)
7. for me personally, calculate how old I am with an hourly accuracy and add to the status bar (full status bar is 100 years old)
8. ability to read pdf doc fb2 etc
9. have a dictionary for writing down a word-translation, a word-definition,
well, this is what I would like to see in the application
What we have from me is a strong desire to implement it, a complete lack of understanding in programming what you need to know and be able to do, no knowledge of the English language
What would I I wanted to get a more or less structured structure in the answer
, what to read and recommendations for chewed tutorials (not self-taught copypasteers)
I understand that you need to know Java, only after reading simple questions remain, where to write the code, how to understand what other programmers wrote in the code, and how to build the code correctly,
i.e. so that you can get rid of wandering in Google and waiting to find something understandable
I would be very grateful for the answer.

Answer 1

Start with Hello world. Even the coolest developers start learning any platform from this.
Further complicate, only gradually.
When you pick up a decent porridge and stop understanding anything in it, start all the same, only anew. And at this point it is very useful to start reading theory about application architecture, algorithms, and so on.
Well, then you will understand.
I don't know how without English. English is still needed. Learn in parallel, if possible, even with Google translate, but you will have to read literature in English sooner or later.

Answer 2

1) Come up with a SIMPLE task for yourself.
2) COMPLETELY formulate it.
3) Go to Google and look for implementation examples.
4) Trying to implement.
This is the first option. The second - take the book "android for dummies" (conditionally) and read and make examples. The literature was recommended in other matters.
What you described about the application does not even look like technical specifications. We need better wording for you.
