Get a book, duh!
If you really are interested in in developing for android, and I don't mean some half hearted effort, then learn how to code in java.
$1 gets you a reply
I would recommend "Introduction to Java Programming - A comprehensive version" by Liang and Pro Android 3.
I seriously recommend to begin with pure Java and then begin with Android development. You get a much deeper understanding in what you do then.

[Q] QR Code...source code for a small app

want to create an app to generate a qr code in the phone itself without connecting to internet..it should be having 3 details..name,phone no,email-id...ny source code or nythng to help me out ..this is my first app .
You want to create such an app? Than you have to start coding I guess, if you dont know how to code it, search for information on the web. Starting with:
http://en.wikipedia.org/wiki/QR_Code
http://www.denso-wave.com/qrcode/qrfeature-e.html
A hint: You have to know what you're doing when you want to code something. So if you don't know how to create an QR-Code, than you can't develop an app. Makes sense right?
EDIT
I use these sites to generate my qrcodes:

[HELP] Decompile APK, fix, Recompile help

Hi, before all, sorry for my poor English.
I have buyed a new Android Watch; the SmartWatch U8. I have found many Android app to run it but nothing have great result.
After few test and search I have found the original APK for my watch, is run good but have some problems and I want improve it.
I have decompiled the APK (APK to ZIP, dex2jar and APK Tool), I have now some .jar files, the .manifest and few assets and others ressources.
Using Android Studio, I have tried to recompile, without modification of code. I have many, many errors.
Some errors is about depriciated, others is for unknown command or class.
I have tried to fix, but no chance, too many errors and my Java skill is realy low (I'm better under PHP). I have also try to copy only few codes using the error tools to known what is needed to add, but I don't known own the default structure was made (all class in same folder ?, or many folder for many class ? less class but with more actions ? not sure)
I have tried all ideas I have found, no valid result, I never build the app with success. I have made few Android App, with help of tutorials and are very basic (Web browser for my website, music player and scanner). I known the basic of Android coding and the new and old way to code them (Eclipse and Android Studio).
I search many solutions;
- [easy] Find another app with all (or the most) of needed change I want; hide the notification text but keep the icon when connected, more control of what is sending to watch (keep notice of call, but not make/answer call over the watch)
- [medium/hard] Find a good tutorial/guide for rebuild a Android app from decompiled APK.
- [hard] Build from scratch a Android app for my watch (with tutorial/guide)
The APK I try to edit: levelkro (dot) com/download/android/KHR1.3.22.apk (not available on Play Store)
Thank for your help

Urgent help please

dear community i hope everyone are doing fine, so am gonna go straight to the point
i have a Magisk on both mobile and emulator with all important plugins installed + Frida well installed + many http interceptors + installed the http interceptors certificates in the root ...
- now i have a game that i want to mod and i want to explore as well. the problem is i spent the last 4 days decompiling it and reading it's source code and i couldn't find any urls i even tried using frida to bypass the ssl pinning and i did bypass the ssl pinning and the root detection and still no links and when i use burpsuite the game show other links that has no relation to the game api.
also to mention that when i use this tool HTTP Toolkit and i setup the tool with adb to intercept the calls the game says that the connection to the server is lost and game freezes .
i tried every possible solution before coming here trust me and the last thing is i found these errors in the output from frida which i couldn't find in the source code because there is no functions named
HTTP.SecureProtocol.Org.BouncyCastle.X509.Store
BestHTTP.SecureProtocol.Org.BouncyCastle.Crypto.Tls
......................................
now my question is : can someone give me any idea on how to get the requests without letting the game freezes
another question : if the links aren't present in the apk source code from where the tool is getting those links to perform the api calls
third question : is this has any relation with libraries .so ?

Game Url : https://play.google.com/store/apps/details?id=com.lockwoodpublishing.avakinlife&hl=en&gl=US

i hope i can get some help from your guys and thanks in advance ^^
