I have developed the Google map application in android using Eclipse and AVD. Is it possible to run the application on device or I need any development certificate to install application on device (just like iPhone).
Kindly guide me so that I can test my application on my device.
You do not need a certificate you need a phone with debugging enabled. Read this article: http://developer.android.com/guide/developing/device.html
After an successful installation of your app, you might want to read this article: http://developer.android.com/guide/developing/tools/adb.html
Although you might want to ask at stackoverflow.com for programming related questions.
