Thanks I will try that

if you know anything about variables and values, if and switch statements, and booleans you could use appinventor. No java experience needed. You cant upload the apps to the app market, yet, but you can test and run on your own device. I'm pretty sure you can send a link to folks you know to download the app too.

You can use the Google App Inventor. It's kinda like the old visual basic, etc, but it should give you a head start...

Now we need Devs!

I'm willing to test any and all roms, themes etc. for any devs. Just let me know. I'll be getting a different phone so I'll just use the Zio as a testing ground!
okay guinea pig... since the rom seems to be deodexed. see if any of the blackbar mods for froyo work
I'm already a step ahead of you. Ill post what works tomorrow.

I would also know how that worked. I would love to have a black bar instead of this grey one.

Sorry for the late reply. I've tested three of the black status bars without any success. Still learning.

Where is the status bar located within the file system? I want to see if there is anything I can do.

I found the location of the status bar. Check my thread for more info. I think we just need to do a little work.

Well Im going to teach myself Java because supposedly it is prerequisite for learning to develope for android. I came across good 101 Java tutorials online. I just really want to mod roms for my zio and maybe even start creating an app.
Any ideas?
I'm currently taking Linux+ so I should be of some help.
Sent from my Zio using XDA Premium App
Yeah I'm not going to start taking OS classes for my major until I start taking core classes. In either case Im going to start early with Java. My school library has older editions of Java textbooks I think but I'm to check them out AZ well.

You can develop full apps with java and xml for the layout. Being familiar with linux is also a must, since android is just a linux flavor.
http://www.thenewboston.com/ is a great place for a beginner or guru. Tons of video java lessons as well as android development.
Linux has helped me with the file system. Although I still have alot to learn before I am any kind of guru.

everything of importance on android phones is written in java.
But the kernel and file system is Linux based. You have more on your phone that you wouldn't think you would have on a phone.
Sent from my Zio using XDA Premium App
Yes, the OS is linux based, however all the apps are java based.
Here, read this
Its from cyanogen himself. Good place to start if you want to get involved with android.

The Android platform is basically a linux flavor. It contains more then a linux the file system and kernel. Yes exactly what I posted, Java may be used in android development. That is not the only language, There are a few others including C.
Thanks for claryfing the different programming languages and their relevance to the cell phone structure and android OS.
Java and linux are both important for exploiting and developing in other words.

I got a game that there is not a single clone of it on the market.
Quoridor but with online play like words with friends or wordfeud, where opponents have unlimited time to play a move or a certain daily limit. Also would have chat and multiple games at one at least 2 players but 4 players would be awesome.
Let me know if your interested.

[Q] KFHD App.

Hello. I was wondering if one of you could put your huge brains to work on making an apk run on KFHD7. The app is for a local news station in Portland, Oregon.
GooglePlay link:
https://play.google.com/store/apps/...sMSwyLDEsImNvbS5rcHR2LmFuZHJvaWQud2VhdGhlciJd
It just doesn't work on the KFHD7 yet. Or at least I'm not able to download it from the market. I've tried to find it online, but the links all take me to the market or the 1 or 2 apk's I find don't run. I hope that this app just needs a few tweaks. But I am part noob, so what do I know.
There's no way that I would expect someone to do this. If it's a pain in the rear, then I would forget about it. If the process can be explained easily, then maybe someone could tell me how to do it. If not then, oh well.
Many thanks for even taking the time to read this.
If you have it installed on another android device, go to your Data/app folder and get the .apk yourself.

I tried that too. It didn't work. That's why I figured it would need some tweaks to get it to work on Kindle. It's pretty cool app for what it is.

Learning java

What books or pages of Internet do you recommend me? (if it's in spanish better but it doesn't care me if it's in English)
Go to the new Boston tuts on YouTube

Check Head First Java book if you want to have a hard copy you can check any time
Are you using that to learn java? Is working for you?

In Spanish i use Oracle Java 7, it's great
Get all the documentation you need, on line straight from the horse's mouth.
http://www.oracle.com/technetwork/java/javase/documentation/index.html
Sun originally developed Java, before Oracle bought them out.
The "Java resources" panel to the right contains some pretty useful stuff.
Like C# and the .NET framework, Java has thousands of objects you can use, to the point of almost total confusion.
You will need to keep one eye on the API definitions, unless you have a specific IDE that is aware of the version that you are trying to code, and can prompt you for the parameters to methods etc.
It is currently only in English, Chinese or Japanese.
Tutorials: http://docs.oracle.com/javase/tutorial/index.html
Bruceeckel.com. the best

IMO it would be better to buy a book that teaches Java... it is not a simple language so you'll have to study it very hard
Use roseindia website. Java mentals and genious group there. All tutorials are there.
Use console dont use IDE for beginning. Good luck.
Sent from my GT-S5360 using xda app-developers app
Also this site here is great! I've taken a look at it and it teaches the basis of the language, very well done.

Google is my master for programming.
Sounds cheesy, but I am serious. I usually look for ebooks and youtube tutorials through google. I think someone above has already suggested this, but boston tuts is great. Other than that, I use stackoverflow for any questions i have. they are a very professional community that is able to provide very clear and detailed answers to any problem you are having.
Just make sure that you program while you learn. Just watching 3 hours of youtube tutorials will not help you. You will definitely have to spend a considerable amount of time actually writing programs and debugging them(80% of that time will be you banging your head on the keyboard : P )
Stackoverflow good for android too. Main is usage of our own brains. Even oracle may not help in many cases.

it depends on which part of android you want to develop java is a very small part of android, basically apps... xml is pretty much everywhere... but i would recommend to study C because you need it for kernels and many other stuffs
Look I am not interested in kernel right now but want to develop apps & port mods too ? Any idea what I should focus on ?

Java it is.
But learning C won't be a time waster because its the kindergarten class when a student wants to become a programmer. But for the sake, learning Java is more than enough to develop apps.

I as well am just entering the world of developing. I have never used java or any code for that matter. Ive read alot and id like to start modifiying or porting small android apps and widgets. I have as far as i know, everything required (android sdk, jde, eclipse..) but im still somewhat in the dark about decompiling, changing content and eventually recompiling. Any tips for a Newbie making his way?
