I have an android application, I want that application to use in blackberry. Is there any way to convert android application to blackberry application?
Not that i know of. But if you're developing from scratch you can try a cross platform mobile framework such as appcelerator phonegap or adobe air
If your application was build with phonegap then you're in luck. Your application was built using standard web technologies like HTML5 Javascript etc. The phonegamp software is a wrapper that lets you native api calls for your particular phone. All thats left to do is deploy to your targeted device.
The pages below show how it works and what oses are supported
