Ideas for Google Android Challenge

Hello all,
This post is in regard to the Google Android Challenge put out by Google to create/develop new software for the Google Android shell. If you haven't had a chance to read about it, it's basically a new OS created by Google to run on any type of PDAesque cellular phone. The challenge issued is then to develop new software for this OS (written in Java) so that when it is released it will have software available for it.
My question to all of you is what software would you like to see developed for this new OS? The reason I am asking for ideas is because I am a CS undergraduate student working in a research group to create one of these programs. Ergo, I figured asking you guys what you'd like to see created would be the best way to get ideas that will make sense and benefit the community.
Any ideas you submit here may be used in the creation of new software--if you require idea copyrights that can be worked out.
Thank you all in advance,
Jake

Hello Jake,
We'll I'm a Java programmer too, not thinking of entering the challenge though. Had a quick look at the SDK for Android and it does'nt seem like pure java, more like a hybrid of C and Java does'nt it?
Since I have'nt had a thorough look at it, I'd like to ask you a few questions regarding the freedom to program on the platform.
Since it does'nt use the "normal" JVM but googles Davlik where theres no byte code but script code, does it allow better interaction with the hardware, and is it faster? Also can you implement equallizers and other effects in a media based application, which of course was not possible on J2ME. I was thinking on a All-round mediaplayer for Android, something like Rockbox which maybe found at www.rockbox.org which is a linux based program used on iPods etc.. but has been ported to Linux based EZX phones.

Secure SMS - What platform is best suited?

Hi all!
I want to develop a Secure SMS application for mobile phones. The idea would be to first add some security primitives to the OS and then to use these to write secure applications (such as SSMS).
Now, the thing is that this is experimental, meaning my goal is not (yet) to distribute an application reaching the most people, i.e. I would like to first limit the project to one platform and see how well it works there.
My question to you is: Which platform would be best suited for that (or alternatively: which platform should I avoid...), i.e. which platform has the best SDK for this kind of thing and how easy is it to do?
Thanks for your answers.

Well, to really be honest with you, my experience tells me that secure SMS ans secure-whatever will be best suited to those blackberry people. The reason they do buy a blackberry is for it's security, or so it seems.
Us Windows Mobile users could of course take advantage of an app like this, and it's way easier to program for a WM device, since there's emulators and SDKs everywhere.

Easiest platform actually would probably be java then its portable

[Q] IDE similiar to visual studio for app creation?

I'm wanting to get into making apps, I'm fairly decent with java, although c# is my primary language. I'm used to the way that visual studio accentuates my newbish programming by making windows forms and event handling for things like buttons so easy. For example, just double click a button to start coding the event handler. I would love to do this with making android apps, but correct me if I'm wrong, you cant really do it that easily with eclipse. It seems like you have to either manually right the code to the forms such as button placement and size. I know there is a web app called appinventor and while it is noob friendly the fact that it doesn't give source code is very annoying. Any help making this transistion would be greatly appreciated as i would love to start making apps

You could try something called as basic4android.

here is the official n basic development link:

Basic4android includes a real WYSIWYG visual designer. The performance of Basic4android applications are similar to the performance of applications created with Eclipse/Java.
Basic4android creates Java code under the cover. You can later work with it though it is usually not recommended.

Try IntelliJ IDEA 10: free IDE for Android development -
blogs.jetbrains.com/idea/2010/10/intellij-idea-10-free-ide-for-android-development/
It's much better than eclipse. Also read stackoverflow.com/questions/239732/things-possible-in-intellij-that-arent-possible-in-eclipse

PhoneGap and Corona - how do they work?

PhoneGap and Corona are both cross platform mobile app development environments, but how do they do what they do?
Well I'm a PhoneGap Build user and I recently DLed the PhoneGap add-ons for my Eclipse dev environment. With PhoneGap you code your app in HTML5, CSS£ and JavaScript and it turns it all into an Android app for you.
I think I've worked out that PhoneGap takes your web pages and just wraps them all up into what is essentially a stand-alone website that acts as an app.
It's a nice idea if you want apps that are purely information, like some of the medical apps for healthcare professionals, but it's not so nice for smoothness and transitions or even interface elements e.g. you can simulate a Tabbed layout but it's not as neat or a smooth as a real Eclipse coded Java-xml Android Tabbed layout.
PhoneGap can repackage your web "app" for iOS, Andoird, BlackBerry, Sybian and webOS! That's one big bonus.
Now does anyone know how Corona works? Seems it's only for iOS and Android and I'm wondering what the underlying structure is. Anyone know?

No one knows?
It's be useful for developers to have insight into this. Afaik Phone gap don't have this info in their docs, I've just worked it out.

Corona is more of a Game Engine I think
It's basically it's own API/SDK/Engine. You code works within that. It looks like it uses lua script but I'm not sure.

Phonegap and other cross platform tools
Hi pizza_alarm
There are basically 3 types of multi-platform approaches:
1) the super-simplistic. These are not really programming at all, but simple tools to auto-generate an app using rss feeds, and other fairly generic settings.
2) browser-hybrid. Most of the serious contenders would fit this category, even though some claim to be in the 3rd. They use html + css to describe page layout, and some (like phonegap) allow full access to any browser-supported scripting, like javascript. At build time, a pre-compiled "player app" is bundles with your web app
3) native compiler. These let you build your app in a intermediate coding language, which then gets recompiled for each platform. Many of these still use the techniques described in item 2.
We have recently published a free comparison between all the serious contenders (items 2 and 3 in my list). Tell us what you think:
(I don't have permission to post the URL - but if you google "triballabs cross platform" you will find it)

Sorry - I meant to add that we use phonegap. One of the bits we like most about it is that you get all the source code, so if you need to enhance the basic "player" app it is very easy to do. Obviously you need to code these native, in Java or Objective-C or whatever your platform calls for

I use Corona since 2013. I have made this game Stronghold. It's easy to use, but there is a lot of limit, no multi threading, few plugin, few quantity of documentation, the app always do imagesheet in 32bits. We have to pay for many things. Like remove the launcher image (actualy it's write corona sdk XD)

Do I need to learn Java to program in Android Studio?

Do I need to learn Java to program in Android Studio? Or I can just jump straight into it? If I must learn it, can u guys show me a great way of learning Java? (I have a Pascal basic BTW).

You definitely must. Java is the main language for android development and without knowing it you can't do anything advanced.
To start learning you can use docs.oracle.com/javase/tutorial/. But learning is nothing without practice so start your own project and use Java in it. It's relatively easy language so you can start quickly.

You are welcome. To be honest I don't know any video tutorial and personally I think the best way to learn programming is practice. So just use any Vogella's tutors and code your apps but always try to make them more complex.

Java is important for Android studio
Yes, you need to learn Java properly before visiting android studio.
Because Java is key to do programming in android studio for Android developers.

I learned from a YouTube series called "mybringback" 5 years ago. It's still a good place to start. Also, a great website that interactively teaches you to code is Codecademy.com. They are mainly a web-development website, but recently added java to their courses. It may be worth trying as well.

I have collected many good tutorials for Java and Android here.
Hope it helps

It best to learn Java, but today you can also use Xamarin to develop cross platform apps using .net (Visual Studio 2015).

java is main language to android studio
if you are using android studio, Java is a must. But you don't have to learn core java, you can just jump in to android programming, coz there are lots of different library there.
i would suggest using android studio instead of others, beside they are free, they are directly from google

Yes, java is must in order to develop android apps. Android virtual machine runs java codes. So android apps needs to be in java.
Now a days, there are so many frameworks and tools available which allow you to develop android apps in other languages and convert the apps developed in other languages to java code to deploy and run on android.
I think it is a good idea to directly code in java as you can easily understand concepts involved in android os and develop apps that perform well proving best user experience.. It is not difficult to learn java and android framework to develop android apps.

As others have pointed out, yes you must. However, if you have Pascal/Delphi background, that helps a lot! So loops/ifs/functions are no stranger to you. You "only" need to learn about classes, interfaces and such stuff, not very hard.
Luckily for you, there's literally thousands of Java tutorials, books, videos, anything you can think of. I always like to stick with books from respected authors and/or the language authors. So for Java, I'd go with https://docs.oracle.com/javase/tutorial/java/nutsandbolts/index.html (just an example, there's tens of other valuable books/tutorials).
