This is issue caused to variation SDK versions.

I think Galaxy 5 runs OS 2.1 and your sdk target your project might be 2.2 or above..

Try setting the <uses-sdk android:minSdkVersion="4" /> in your manifest file of the project.

As Jana said. this may be sdk version problem. But what i think is you have not signed your app. Please check this http://developer.android.com/guide/publishing/app-signing.html
