Android 3.2 SDK installation problem, “Done. Nothing was installed.”

anmolanand — Sun, 21 Aug 2011 18:31:15 +0000

I was installing Android SDK and was downloading the required packages, and while installing, my Anti-virus, restarted my laptop.

When I rebooted the laptop and tried downloading the remaining packages, I got this error “Done. Nothing was installed.”

I searched for the solution for the problem and found that if we run “sdk manager” as administrator, and, follow the normal steps, then this problem is resolved.

You can start the sdk manager by typing “sdk manager” in the start menu and follow the step mentioned above.

JDK not found, Android SDK installation

anmolanand — Sat, 20 Aug 2011 17:38:22 +0000

My windows had crashed, and, was reinstalling the software.

I was installing Android SDK API revision 12, and the JDK version that I was having on my system was JDK 7.

When I started the Android SDK installer, it said that, it was unable to find the JDK on my system.

I searched for the solution on the net, and, the simple solution for this (if you have a compatible JDK installed) is to just to press the BACK button and then press the NEXT, and you will see that, JDK is found.

This simple solution helped me solve my problem, I hope it helps to solve yours too.

Thanks

PocketSMS and MorseTrainer version 1.1 developed

anmolanand — Sun, 31 Jul 2011 07:06:58 +0000

Hi,

I have developed version 1.1 of PocketSMS and MorseTrainer.

PocketSMS version 1.1, allows you to send a message to the person of your choice by typing in their number, and, apart from that the problem of automatic opening of the keyboard when moving from reading to writing section or vice-versa has been resolved in this version.

MorseTrainer version 1.1, shows the morse code of the alphabet that you want to learn, along with vibrating it. Each dot or dash that is being vibrated is also shown one by one being appended to the text currently present in the textbox.

The app will be available shortly for free download from http://www.bapsi.org/Home/vibrations-series-of-products-for-deafblind

Thanks

Anmol Anand at EFY Design Engineers’ Conference-Innovator’s Talk

anmolanand — Sun, 10 Jul 2011 18:07:23 +0000

I spoke at Electronics For You Design Engineers’ Conference-Innovator’s Talk in EFY Expo, that was held from 17-19th Feb 2011 at Pragati Maidan, New Delhi. I was representing Bapsi in the conference.

I know, I am posting this quite late, but, the reason for posting it now is that I found the video of my presentation at the EFY Design Engineers’ Conference-Innovator’s Talk, and, therefore, I thought that I should write a post on it.

In this video or my presentation I am telling about modules of SKID, that I had worked on in my graduation summer training.

Apart from SKID, I introduced the concept behind the SMS application for Deaf-blind that I had started working on, in this presentation,and, the ideas which have now culminated into an app named PocketSMS, in the five months that followed this presentation.

The link for the video of my presentation at EFY Design Engineers’ Conference-Innovator’s Talk is given below :

Eclipse : Java was started but returned exit code = -1

anmolanand — Sat, 18 Jun 2011 19:05:44 +0000

I was having eclipse on my system (eclipse 3.6 – helios version), and a week ago, I decided to set it up for doing Android programming in Java.

When I opened Eclipse, I got the following error :

Java was started but returned Exit Code = -1

The error was same as shown in this image ( i have taken this image from the world wide web )

I googled this error and found that many people had faced the same error and there were many solutions available to this problem.

Most Common Solution : One of the most common solution that I found was of adding some lines to eclipse.ini file, For example: The path to the javaw.exe file. Adding some arguments to eclipse.ini file was also suggested.

This solution had solved the problem of many people, but, it lead to some other errors in my case( example : unable to find java virtual machine on the specified path).

I tried re-installing eclipse but the problem remained as it is.

Then, I decided to re-install my jdk and jre to the latest versions that were available.

I removed all the older versions and re-installed latest available versions of jdk and jre.

When I tried starting eclipse again, it started.

This solved my problem

If you are facing the same problem, then I suggest you give it a try once to re-install jdk and jre, and, see if it can help.

All the best!!

App Inventor : Blocks editor opens but it’s blank, work lost

anmolanand — Sat, 18 Jun 2011 15:48:59 +0000

Hi!

I making an app that will enable people who are deaf-blind to send and receive sms. I have been using App Inventor for quite some time now, and, I am using it for making an initial version of that app.

In this post I will be discussing about a problem that I faced in App Inventor while making the app, and, I will also discuss it’s solution.

Problem : I designed and programmed the app using web browser Firefox in the afternoon. When I tried to load it at night, the Blocks editor opened, but, it was all blank, and, all the work that I had done had vanished.

Solution : Close the browser in which you tried opening the blocks editor using App Inventor initially, and, try opening using another browser.

In my case, I case I opened the app using Firefox initially, but, after the error occurred, I shifted to Chrome and everything worked fine.

Caution : Don’t open App Inventor in two browsers at the same time, as, you can lose your work in such a situation.

All the best … Happy Learning

Using Derby database in Netbeans IDE

anmolanand — Wed, 15 Jun 2011 19:23:23 +0000

I was working on my project, “Public Distribution System”, and, I needed to use a database to store and retrieve data from the database. I tried the Type 1 connectivity with SQL Server, but, was unsuccessful.

I tried to correct the problem for around 10 days, by trying almost each and every solution given on the internet, but, none proved fruitful.

Some of my batch-mates were also unsuccessful in setting up Type1 connection, and, I am not sure if it was a coincidence or not, but, all of us were having Windows 7 OS (64-bit version) on our laptops.

Then I decided to go with Type 4 connectivity in Java, and, while I was searching tutorials for the same, I came across a tutorial explaining how to use Derby database in Netbeans.

The tutorial link is as follows :
http://netbeans.org/kb/docs/ide/java-db.html

This link was easy to grasp and has explained the using of database in a stepwise manner.

So, if you are also stuck in setting up a database connection, then, I hope my post will help in providing a solution to your problem.

All the best
