It seems as if every Android application I really want to make is impossible to make with the current SDK. It doesn't give me access to certain things I would like to work with. This is an example of one of these things.
I know it is possible since I've seen apps in the market that do things that the SDK cannot do. My basic question is can someone point me in the direction of how to create such an application. I've searched around, but all of the links I've found are for developing with the SDK. A simple link to a tutorial that can show me how to access Android elements that aren't available through the SDK would be great.
Thanks.
You will not find a tutorial on it because the NDK is in flux..
What I have found is ..
One of the Eclipse CDT has blog posts on how to setup NDK projects in Eclipse.
The people who know Android Embedded C and frameworks are usually on certain IRc channel.
Plenty of code documentation..
Google search for android jni wrapper blog posts.
But keep this in mind several areas require state management as hey interact with hardware buffers in a certain way..ie audio..video..etc.

I've searched a lot through the web about this topic (even on StackOverflow), but the questions I was looking at weren't able to help me, so, here it is (Although im very good at it, english is not my native language, so I'm sorry for any mistake made): (SKIP TO EDIT)
I'm making a simple chat program in Java (self learning), and, at first, I wanted to access a file on my computer. I soon found it hard to acomplish, and decided I wanted to access a drive folder on MY account. So, I googled about a possible Google Drive API. And I found it!!!
I downloaded a copy of the API to my PC, and then i went online to know how to use the API, but the README.txt file and the youtube tutorial were not helpful at all, because i could not understand the instructions. I Looked everywhere but still didnt find an easy-to-understand answer.>
So, im asking if any of you could provide a step-by-step tutorial on how i can accomplish my goal. Ive created projects on the API consoles, but im a bit confused on what to do with them (possibly going to delete them).
EDIT/REDO:
I'm making a chat program, and I want EVERY copy of the program to access a folder on my personal Google Drive and get certain files from it, where ever the user is, and without him having to see the OAuth 2.0 Autorization screen(if this last step cant be skipped, I'll work with that too).
The problem is that, although i have checked the README.txt and the youtube tutorial, i still dont understand how to use the API in the way i want.
So, im asking if any of you could provide a step-by-step tutorial on how i can accomplish my goal, i.e, (Some code could be of great use):
1st-Do this;
2nd-Do that;
...
(n steps)-You are ready;
Thank you in advance!!
P.S.: this is my last "free" question, so if this specific question has been answered please comment it out.
To start using Drive API, you may may want to follow and complete the steps given in Java Quickstart.
Then to integrate with the Drive UI, you may want to check the following references:
Enable the Drive Platform - to get started integrating with the Drive UI, you need to enable the Drive API and provide configuration details in your API project. This gives you access to the API as well as access to UI integration features.
Install Your App - Google Drive lets users install an app by approving an OAuth 2.0 access request.
Open Files - this page describes how to integrate your app with these Drive UI features to open files stored in Google Drive
Hope that helps!
I'd like to have advertisements in an android App I've written and built using PGS4A. I've done my research and all, but there doesn't seem to be any online resources that explains how to do that just yet. I haven't much knowledge on Java either, which is clearly why I've written that in Python. Has anyone found a way to achieve that? If not, how difficult would it be to convert the project files into an Android Studio (or even an Eclipse) project? (so then one can just implement the ads following the Java Admob documentation found everywhere)
Thank you in advance.
To access Java already implemented version you can use pyjnius. I tried to use it for something else and I didn't succeed. Well, I yielded pretty quickly because it wasn't necessary for my project.
Otherwise, I am afraid, you will have to implement it yourself from scratch.
I never heard about a finished solution for your problem.
If you succeeded to use PGU, it wouldn't be so hard.
If not, well, I wish you luck, and put your solution online for others.
There is an Eclipse plug-in for Python. I think that Android studio does not support PGS4A. Never needed it. Console is the queen.
Edit - I know there are similar questions to this on SO, but I feel my specific questions are not duplicates at all. If you disagree with me please bring them to my attention before downnvoting or closevoting! If you can prove to me that my question is a true duplicate I will delete this question myself!
My understanding of the GWT is that it provides an SDK and API that allows you to code in Java, and it generates all the client-side HTML, CSS and JavaScript required to run a full-fledged web (or mobile web) app.
My understanding of PhoneGap is that it allows you to code against its JavaScript API and, through configuration, allows you to tell it which native mobile platforms (Android, iOS, Windows Phone, etc.) it should create nativee wrappers for. Hence you "write once, run many" with it, turning your JavaScript code into a native Android app, native iOS app, etc.
If these two assumption are incorrect, please begin by correcting me! And, if there are any caveats to these assumptions, please let me know!
Assuming my understanding on GWT and PhoneGap are more or less correct, I want to try and use them together for an app that would be available as (1) a web app, (2) a mobile web app, (3) an Android app and (4) as an iOS app.
I want to "daisy-chain" these two in my Ant build, whereby my pure Java code is converted (via GWT) into JavaScript (that complies to the PhoneGap API), and then a second build process uses PhoneGap to create and deploy:
A Java WAR (web and mobile web app)
An Android APK
An iOS binary (I believe this is an IPA file, but I may be wrong)
So with those as the "givens", here are my questions:
Is this possible? If not, why? Any way to hack- or juryrig-together a solution that forces this to work?
I've noticed something called gwt-phonegap - will I need this in order for my proposed solution to work, or would this library just be a "nice to have"? Why or why not?
Any other considerations I am not thinking of here? Other libraries or tools that would behoove me?
Note: I have heard (but am not asserting!) that Titanium is superior to PhoneGap. Titanium, however, is not free. And I am quite broke. Thanks in advance for any help here!
There is an open source project out there combining GWT & Phonegap to build mobile apps:
mgwt - http://www.m-gwt.com
There are many people out there using it to build mobile apps and there is quite a lot on documentation including videos there, especially this one:

I know similar questions have been asked before but i think this is slightly different. for about a year Ive been learning Java. I have been building a few applications on the desktop using my-eclipse and swing GUI. Now i want to start programming for the android. I understand how to do what i want in Java but it all seems very different on android. Does anyone know of any good tutorials or videos out there with step by step instructions showing examples of android applications so that i can learn and build off of them? Most of my programs are simple and for the most part i just need to understand how to interact with the interface (IE the buttons, label or text views i think they call them and so on). I've searched all day and I cant find anything good.
I found this quite use full apart from the tutorials from the developers site.
If you are looking for advanced tutorials , you can try here.
for the most part , once you are trying a specific application , a google search could get you a relevant tutorial.
goodluck.
ps. It helps to read dev guide before you begin to write programs for android.
You should have a look at the Android API demos. They include a lot of simple examples which access special problems/tasks.
A more complex 'productive' application is the Android app for the I/O conference. It's Open Source - so you can have a look 'inside'.
the Android developers site has a great dev guide and tutorials to try out. the dev guide can be found here. The tutorials can be found here.
I highly recommend "Android Programming Tutorials" by Mark Murphy - http://commonsware.com/AndTutorials/. I found the step-by-step tutorials to be very helpful, and it does focus on teaching Android development rather than Java.
I have a general old-fashioned phone that has no special app system and uses Java (I assume ME) for the few applications you can use on it.
This is still a decent userbase and I'd like to start programming for this type of phone. I already know basic Java theory and syntax, so.. where do I get started for programming for non-smartphones?
Best programming environment for Java ME IMO is Eclipse with EclipseME. Includes lots of built-in stuff about packaging your midlets etc. The SonyEricsson wireless toolkit is great for PC-based testing and debugging, but don't forget on-device testing!
If you don't know much about Java ME's lifecycle, then get reading as widely as you can, and try lots and lots of examples. Start with the JSR-118 (MIDP2) javadocs; you'll want these open on your desktop at all times while coding.
Don't waste too much time with the form-based user-interface; I recommend either rolling your own using Canvas, or read about LWUIT.
You can do all sorts in Java ME and target a very broad range of handsets. HTTP capability is guaranteed, so you can hook up to a public web service, or create your own using something like Google Appengine.
Finally, you can release your app very easily on somewhere like Get Jar. Don't be put off by those who say "no owners of Java ME handsets want apps", you'll find the most popular user bases on this site will be users in countries such as India and Indonesia.
Good luck!
I would start with a book on J2ME and work from there.
Try Beginning J2ME: From Novice to Professional.
You could also download the J2ME SDK and play around with the example they give.
For tutorials have a look at the stackoverflow question https://stackoverflow.com/questions/584923/do-you-know-a-good-j2me-tutorial as mention in my comment.
I started with writing simple Flashlight application (choose how much seconds screen will remain lit) in NetBeans ME. And other app which I mange was Countdown with some graphics and sound. After that I found limitations too much annoying and now I'm waiting for my Android phone.
in short:
If you want to try it out - you don't need to buy books. There are plenty of tutorials around.
But, if you want to start deep development - don't waste time.
