Error while running from Eclipse

I have created a very basic project in Unity for Android and exported, later I imported from Eclipse and run in the ADB, however, I see the error at run as below.

12-18 01:33:55.044: E/AndroidRuntime(912): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.embed.unity1/com.embed.unity1.UnityPlayerNativeActivity}: java.lang.NullPointerException

since it was created in unity, you will surely encounter such problem because of issues in platform compatibility. you won’t be able to run that in an eclipse platform. you can only run your project in unity platform. it is because unity has its own platform that enables it to be able to create different projects in different platforms.
