Recently I found out running and debugging large scale Android Application is really slow in Android Emulator. Yes, Slow PC make it even worse.

Here is a quick fix.

Android-x86.org and AndroVM.org has developed a Virtual Machine images which we can use Android as a separate OS within Orache Virtual Box and VMware as well.

Awesome thing is using these VMs we will able to Debug our Android Application as well. Everything just work as it is Android Emulator, But its super fast than the lagging Android Emulator.

Here are the links.

I have used this JellyBean Tablet version of Android VM inside Oracle Virtual Box 4.2.6

How to ADB Connect and configure for debugging.

Hope this helps for Android Developer someone who is looking to get rid of slow Android Debugging.

The most important fact Google Summer of Code taught me is the value of Open Source. And the value developing of Open Source software for the world, for the sake of people who lives on it. Open Source is simply altruism. For whom we code like this? Not for anyone, Just for the well being of ourselves. Simple as that! I was worked for OpenMRS in last summer at GSoC. So the programs I have contributed may be using in actual hospitals, clinics some day. People may love those program. They may get the maximum use out of it. But still those software's are Free. Not commercial ones.  Worth Millions but my Organization OpenMRS giving the Software for Free. See how awesome it is. For the sake of humanity, for the sake of entire world that invaluable software giving for free!

I totally love this concept by now, So I am trying to get involve with Open Source as much as I can. (even at my office time breaks i tend to do it.) Do whatever you can, They dont ask donations or other support. Just simple workforce can effect a lot value for the Community.

Being an Open Source enthusiast, Last week I have attended for an Open Source Event Organized by Computer Engineering faculty of University of Peradeniya, Kandy, Sri Lanka.

There I met lots of former GSoC students and Engineering students who are really interested at Open Source. Glad I met Buddhike Kurera who is the Summer Programs Admin of Fedora Project at the event. He gave a lightning speech about open source and the Fedora's role in open source world.



There were various sessions about Open Source and clarifying the value of them. It was a great pleasure for me I got a 15 mins Session to present the audience about OpenMRS.

In their I introduced the people Whats OpenMRS and where OpenMRS being used today.
Actually they were amazed seeing those. Even the Engineering Faculty of the University where I was talking at are using OpenMRS as a research tool, pretty cool right? :-)

GSoC is a good entry for involve in Open Source. So I taught them why they should select OpenMRS as their Organization in next GSoC (if its gonna happen)

I made below slide to present in my session.






The event was a big success, There were around 75 potential Computer Science and engineering students participation. I think they have gained lot knowledge about OpenMRS, Fedora and Open Source Software at the event. After couple of days, as I mentioned in the presentation I saw few Students who participated have posted welcome messages at OpenMRS mailing lists too. That was my ultimate expectation, More contributors for the OpenMRS community, more beautiful things we can get done collaboratively.

Finally I am really glad I have done this, my contribution which I need to do for the World and for the sake of my Organization, OpenMRS.

Last week I have attended to an Open Source event organized by Computer Engineering Faculty of University of Peradeniya, Sri Lanka. In that event I met Buddhike Kurera, who is the Admin of Summer Programs at Fedora Project. In the 1st session he gave a lightning speech about open source and the Fedora Projects role in open source world. In the latter part he talked about the Google-Code-In program one of the events organized by Google for the young kids ages of 13-17 which is happening these days. 





Its a pretty interesting program. So I also thought to contribute this wonderful event.
Younger people are the future of our world. If they got understand the true meaning and value of open source after they grown up surely they will do their best to contribute open source by means its the development of World and Development of Free and open standards.

Since my GSoC Organization OpenMRS hasn't been selected for the list of Organizations this year, I thought to apply for GCI mentor-ship via Fedora Project. And just 1 day ago I have became a Mentor for Google-Code-In program. So in the coming days I will be mentoring young kids for the sake of Fedora Project :-)




This is just a good and simple way to contribute and show your love toward open source.
If you like to become a mentor you are still not that much late. another 24 days yet available to the program ending.

Good intro slides to understand the Basics.
Slides taken from Pradeeban Ayya's Blog.





So Adult programmers, matured students, former GSoC students should become mentors and support this wonderful open source event.


Steps are follows (these info given thanks to Buddhike Ayya)

1. Create a profile in GCI 2012: 

reg as a mentor using this link..
http://www.google-melange.com/gci/profile/mentor/google/gci2012

2. Ask for the mentorship via GCi 2012

aftr that goto menu > request mentor > fedora > writs something abt u.
ur work and bla bla no more than few 5-10 lines

3.When it is approved monitor some task on the list and review them
with the student (please inform the primary mentor before that)
4. After reviewing 2 tasks you can submit two tasks which are fedora related.
5. Then you need to complete it by instructing the student.
6. Repeat adding tasks.

Thats the procedure. Read more and get more knowledge before proceeding cause this is not just an ordinary event, you are dealing with Professional Open Source communities. Respect each others! , Don't cross your limits, use common sense.

Happy FLOSSing! peace.

Tether your phone to your computer.
You will find the option to create a "portable WiFi hotspot". This will be in the options, under "wireless connections" "internet" or "tethering" (it depends on what version of android you have). Once you have turned on the hotspot (you can use the default name and no password, or press "settings" to configure it), you connect to your phone from your PC as you would to any other hotspot.
EDIT: If your phone cannot make a hotspot (it seems the HTC Hero cannot) you have two options:
1) if your phone is rooted, install WiFiTether (code.google.com/p/android-wifi-tether/)
2) if you are running Windows Vista/7, install Connectify (connectify.me) to turn your PC into a hotspot, and then connect to it with your phone. You will find the phone's IP in Connectify's list of connected clients.
Once you're connected, make sure to set your firewall to allow connections to and from other computers in the network (I don't know how to use your firewall, but if you're running Windows Vista or 7, make sure to set it as a "home" network).
And you're done. Your phone's IP address can be found by going to "network connections" (in network & sharing centre in Vista & 7) and looking at the status of the WiFi adaptor. It will be the IP address labelled "default gateway".

This Project has been done for a partial fulfillment of Distributed Component Based Software Development Subject.

Method 1

First try this!

adb shell
# cd /sdcard/clockworkmod/backup/2010-06-29.20.22.53
# rm nandroid.md5
# md5sum *img > nandroid.md5

Method 2 :

If Method 1 doesn't work try this way! Hard way - manually setting MD5 values!

Download this > MD5 Calculator

• Manually go through all the files in the backup folder and calculate MD5 vals, Add them into nandroid.md5 file
