Hey there,
I want to write an App which I want to distribute to different mobile Os. I'd be glad if it worked on iPhone, Windows Mobile, Symbian, Android and if possible otheres.
Now I'm looking for some technology I can use:
What would you recommend? Java, Flash, Javascript-based?
What I need is:
- app-downloadable, so it doesn't require an internet flat using it
- some api to have access to cell id and / or gps for phone tracking
- very easy cross platform publishing without much platform dependant code
I do have good Java knowledge and do code Actionscript 3 since some years. I already found some solutions for cross-platform development, but if there's anybody here with experiance I'd gladly hear some opinions.
I'm anticipating your replies
Hi,
It was not until I started the adventure with Android, but right now I would like to learn a few issues. Suppose that some Chinese have a tablet. Does the official library for Android (Java), there is a possibility of getting into the hardware and GPIO lines suppose to control whether the PWM? If not, you could ask for a sketch of the problem, how to write a library yourself suitable for such things? How do I know, the kernel of Android is simply Linux. Is the structure of the Android file system is similar to classical linux distribution? If so, you can access through the Android API again, to all the common files in the / dev, / sys or / proc? I know there's NDK, which sooner this would be suitable, but unfortunately, terribly lame documentation. Due to the fact that even a little the market is functioning Android application developers write programs mostly in Java, so I thought that such issues are already in library. Thanks for help
Hi Xda developers,
I might get involved in project during internship, where they want me to find way how to connect android device to custom made proprietary radio transmitter-receiver board without bluetooth or wifi, so it has to be direct wired connection.
This radio transmitter-receiver board has its own microchips and firmware so all low level work and functions will be done in this board alone.
Does anyone has idea how this could be done? is it possible to write some drivers (probably C) to communicate with this board over micro usb port present in all android devices? And than how could be data received over radio used in basic java-android application installed on device? (could this be done with use of a binary/text file as a link between these two programs?)
Thanks in advance
If nobody knows or has time to answer my questions, please give me some tips where to start searching for answers (websites, books, magazines .... )
Is it essential to learn Linux architecture properly before modifying anything in android?
I searched xda-developers a lot about IPv6 (Android related) but only questions, no one seamed to get it to work. Now I got IPv6 working on my Android phone and I want to share it.
Of course I can not held any responsibility for anything. I am no developer, just a user, who used Google a lot and who put a lot of single things together. Rather I am not sure why it works, but it does work.
Quick guide:
1. find out if Linux (Debian) is available for your Android phone and learn how to use it
2. find out if a tun module or a kernel with tun support exists for your phone
3. learn how to use IPv6 on Windows (if you are a Windows user) (I was happy with gogo Client at http://gogonet.gogo6.com/page/download-1) and on normal Linux (normal in meaning of running on PC) (I used miredo first)
4. learn what aiccu is and how to use it on PC
5. install Linux (Debian) on your phone
6. load the tun module (or use a kernel with tun support)
8. register aiccu
9. request tunnel at aiccu
10. install aiccu on your rooted Android phone (with tun) inside Debian chroot
11. done, test "ping6 ipv6.google.com" inside console, should work, and test in Android stock browers, it should also work!
Comprehensive guide:
First of all, before you start fiddling with Android and IPv6, which is quite tricky, I highly recommend to learn how to use IPv6 on Windows (only if you are a Windows user) and on some Linux distribution (Debian or Ubuntu recommend, as Debian is imho the most easy to get Linux for our Android phones).
On Ubuntu, which was running in VMware, I installed a package called miredo.(used this guide https://wiki.ubuntu.com/IPv6 look for miredo) It is a great piece of software. I just installed it and afterwards an apache2 webserver and the server was reachable from outside the virtual machine. Furthermore I did run another virtual machine with XP, both virtual machines, XP and Ubuntu where behind NAT (standard network configuration in VMware, setting up port forwardings is quite complicated) and also my router has a NAT and Windows firewall on host computer was also activated. Still... From the XP virtual machine I could access the apache2 running on Ubuntu. Great. You do not need VMware to learn how to use IPv6, of course, you can also use real hardware, but for me, VMware is very convenient.
Also learn what aiccu is and how to use it (https://wiki.ubuntu.com/IPv6#Get_connected_with_SixXS).
After you just learnt how to use IPv6 on normal Linux (normal refers to the normal end user version, no hacked stuff for Android) you have to learn how to use Linux (Debian) on your Android phone.
I used this guide http://forum.xda-developers.com/showthread.php?t=1254283 but you will need another guide for your phone, because this is phone specific. Google the name of your phone in conjunction with chroot, Android, Linux, Debian or search xda. It may not be possible to install Linux on all Android phones. I do not know that and I can not help you with that because I am a Linux noob. Of course, maybe you don't have to use Debian on your phone, I just like Debian because imho you'll find most informations in conjunction with Android about it and because it's more newbie friendly in general compared to other Linux distros. So maybe you prefer some other distro.
Then you need to get a tun module for your phone/kernel or a kernel with tun support for your kernel. Load the module.
You need to register for aiccu and also request a tunnel.
Afterwards, last step, install aiccu. I think I edited aiccu.conf and entered username and password.
ping6 inside Debian chroot is working for me and also in Android stock browser I can access IPv6 websites.
There are quite a lot requirements and things to learn before, I am sorry, because I can not ease this process.
Right now I also can not tell you nothing about how stable this works, how reliable it is or what the benefits are.
Update:
Working - 3g connection on phone (everything only IPv6 of course)
- apache2 webserver
- SSH server - access with Putty
- SFTP - access with FireFTP or WinSCP
Native aiccu for Android
Some time ago, I hacked together a native aiccu port for Android. I only tested it with AYIYA tunnels. It worked greatly both on Android 2.1 in a Xperia X10 mini pro and on Android 2.3 in a Galaxy Tab.
To use, copy the aiccu-android-bin.7z contents to your phone and put your config at /data/aiccu/aiccu.conf.
Please note that you HAVE to use the provided "ip" executable. The one provided with busybox is incomplete for usage with aiccu, and won't work.
The aiccu-android-src.7z contains the source code if someone is interested in hacking deeper. In particular, testing heartbeat tunnels and seeing if any changes are needed to the source would be nice. Also, cleaning up and trying to push upstream would be great.
Nice thx

Very nice. This simplifys the process a lot.
Unfortunately this does not work on my x8. Maybe because busybox is preinstalled with my ROM?
When I do acciu test, it complains about the ip executable. But I already copied both.
Can I get ride of the old buybox ip? Should it work on x8 as well?
T-Mobile USA has an beta native IPv6 service for ICS Nexus S and Galaxy Nexus UMTS phones. You can google the details. It is natively supported on the stock ICS software now using the UMTS network.
New solution:
https://code.google.com/p/gogodroid/wiki/GogoDroid
drawback:
needs ROM (kernel) with TUN (but any app could null that dependency)
First of all thanks for your work of putting all these information together!
I am using a Galaxy Nexus which allready has tun built in to the stock rom (ICS 4.0.4).
Unfortunately I cant get gogoDroid working. It seems it doesnt recognize the built in tun functionality.
So I tried it with the tun.ko module - no luck there neither, since there is no compiled version for the IMM76I Build :-(
Any suggestions on how to get it working anyways?
Edit: I also found another app which supports 6to4 tunneling called IPv6Config - you can find it on the Play market. Unfortunately 6to4 doesnt get thru NATted mobile networks...
Hello all !
Sorry to dig out this old thread again but here some infos about running IPv6 tunnels on a rooted Android phone.
I wrote a little app to simplify the installation, configuration and running the binaries posted by thotypous:
The app is called Androiccu and you can find it in the google market. Sorry, I'm not old enough to be allowed to post a link to it.
It's still in an early development stage but it does basically work for me and I would enjoy some feedback about success or failure.
This application downloads and installs the binaries, creates a config file with your login infos and can start and stop aiccu. All from a GUI, no need to play on a terminal.
Cheers and have fun testing.
why tunnel when you can have native ipv6 https://sites.google.com/site/tmoipv6/lg-mytouch

Because most mobile network operators don't provide native IPv6 yet. You're among a few lucky ones that has such an operator. I'm not. When i'm at home i don't need this app as my router provides natively an IPv6 address to my phone over the wifi network. But on my router itself i have to run a tunnel as well as my provider is also not able to provide IPv6.
The biggest aim of this application is to become quickly obsolete when finally all mobile network operators will be able to provide IPv6 natively.
Best regards,
Martin

I have a sixxs tunnel. But how can I route this to wifi tethering? My ipad is connected to the wifi hotspot from the android, but the ipad can not resolve ipv6.google.com, but the android can do this.
Hello all!
Firstly, I would like to thank many people for their inputs on this site. I have been viewing it for quite some time, so I finally created an account. I cant wait to get in the community!
Now, as for the reason for this post. I am trying to get my ALFA USB WiFi AWUS036NHA to work with my Tab 2 7.0. After doing some research I am with the understanding that I must write the drivers into the kernel. I have a decent understanding of how the kernel works with the hardware and software of the device (the theory of it, rather), but I do not know how to actually edit the kernel. I have done some software developing on Linux, Windows, iOS, and the PSP-1000 communities, but I did nothing with their kernels.
My question is, is there a pre-built kernel with the RALINK drivers? If so, I would love a link to that, but I am also interested in learning how to modify the kernel, for I am mainly a Linux/Android fanatic.
Any input would be appreciated,
Thanks!
Edit : Just for informational purposes, my tablet is on Cyanogenmod 4.2.2. The only thing on it are a BlackUbuntu image, and a Backtrack 5 image, which I boot through terminal.
Edit : I am currently setting up the Eclipse IDE on my Ubuntu system. I should be ready to go by morning. I have been reading references and studying source code for the better part of the day.
