People who are facing problem in running ddms need to add the sdk path to your PATH system environment variable.

I was having problems as DDMS was showing the error message: “Failed to get the adb version: Cannot run program “adb”: CreateProcess error=2, The system cannot find the file specified.” Your reply helped me solve it.

For those who don’t understand, open up your System properties (right-click on Computer > select Properties > click Advanced System Settings). Click on Environment Variables. Under the System variables section, find the variable called Path. Double-click on it to edit it.

WARNING: Be careful to not change the variable name or delete the variable value. If you accidentally do anything harmful, click the Cancel button and start again. Deleting the value of the Path variable can seriously damage your system. Proceed carefully.

Press the End key on your keyboard while the text cursor’s focus is in the Variable value box. If your Android SDK is stored in the folder “C:android-sdk-windows” add the following text. If your SDK is stored in a different folder, change the text accordingly and add it.

;C:android-sdk-windowstools;C:android-sdk-windowsplatform-tools

Take note that you must start with a semicolon as shown below to separate the new entries from the rest of the Path variable value. Also, make sure that the above paths actually do exist in your SDK folder. If they don’t, you’re probably doing something wrong.

Click OK to everything once you’re done. Then you can run DDMS again, and you should see your phone listed.

Additional Tip: It’s best to extract the Android SDK to a folder in the root of the drive, such as “C:android-sdk-windows”. Extracting it to a folder deep inside your hard-drive (such as your Documents or Downloads folder) can cause the SDK to not function properly.

I hope the author of this great article will consider including the above information in it.
