It looks to be a great improvement over Eclipse android application development, Especially when you developing android apps for various screen sizes such as phones and tablets. you must be comfortable developing android apps using the android studio.

However, if you are running Windows 7 or Windows 8, you may have faced some issues running the android studio application. Several users have  not been able to run the android studio application after it has been installed.

I have also  faced this same problem in the first time using the android studio. now here I write few solution using the android studio.

Downloading & Install Android Studio :

Android Studio is a new Android development environment based on IntelliJ IDEA. Similar to Eclipse with the ADT Plugin, Android Studio provides integrated Android developer tools for development and debugging.

Flowing this link you will find android studio official bundle download suitable OS version  for your computer operating system

When you finish download android studio before install android studio simply doing flowing this work.

Note:  you must need to install JDK tools on your computer

Downloading & Install JDK :


If you don’t have JDK (java developing kit) install in your computer try to download & install from this link
After Installing JDK (java developing kit)  in your computer you can do flowing this work .

1. Right click on My Computer, and select Properties.

2. Click on “Advanced system settings” and go to the “Advanced” tab.

3. On the bottom, click the “Environment Variables” button. This will bring up the Environment Variables screen, you will see two sections, User Variables (at the top), and System Variables (at the bottom).

4. Add a system variable with the name JDK_HOME, and the value equal to the path to your JDK install.

This Step might differ based on how your system is setup, but as an example, here are the settings that worked for us:

Variable name: JDK_HOME

Variable Value: c:program FilesJavajdk1.7.0_21
Have you set your environment variable correct? If not add in

Control panel -> System -> Advance system settings -> Environment variable:

JAVA_HOME (value = c:program FilesJavajdk1.7.0_21))
Now you have almost done! all . Now install android studio

Having Problem  with starting and opening an android studio. when you install and using android studio you fall some common issue on your computer with the android studio. here I’m showing  and fix this issue to solve.

Error launching android studio

If you get the error with msvcr100.dll you will still be having problems starting Android Studio, even after you add the system variables. The first time I thought I fixed it by adding.

MSVCR100.dll  problem Solution

If after adding the JDK_HOME variable you’re still having an error message related with msvcr100.dll, you have to download Visual C++ package – 32-bit or 64-bit from Microsoft and must install it on your computer.

At the end, you deleted the JDK from the “Path” variable so you would have a clean start. you can installed the C++ package, added the JDK_HOME  or JAVA_HOME variable, and everything it’s working now.

Download Link for Visual C++ package :

Visual C++ package – 32-bit:

Visual C++ package – 64-bit:

Fatal Error :

For the first time start android studio working good.but when you restart your computer and try to open android studio you may face this small problem.

This issue comes from your installing option if you install android studio for administrative only then without run administration mode you will face this problem if you face this problem here you have two solutions one for complete fix issue and two for every session when you open android studio.
