MapActivity ClassDefNotFoundException at runtime

Question

My Activity extends from MapActivity, I have descried it correctly in the manifest, I have put the <uses-library> tag inside the <application> tag I am building with goole apis library and the maps.jar is there only one time(no duplicates) and the app runs and works perfect on most devices. However I got a crash report with ClassDefNotFoundException which occurred on ZTE Blade device with Android 2.1. I am building with google apis 2.1 Does anyone have suggestions for that?

I am providing the stack trace too:

com.testing.asd.android.ui.InfoActivity extends MapActivity. The problem is only on one device so far. I tested it on Android 2.3 and 4.2 and it is ok there.

I'm not sure if this is the case with the ZTE Blade, but there are some devices (such as the Kindle Fire) that don't have the Google APIs. I think these phones will show a NoClassDefFoundError if your app uses MapView.
