vasu please Use Code Tags when you post a source code. You can edit your message using button and then add code tags to it.

There seems to be a method named setRgbTransparencyBlending as given here. Are you using two sets of libraries?? If yes, make sure that they are compatible with each other. Also make sure that the library is getting packaged in your application so that it's available at runtime...
