App runs on emulator but not on device_问答_开发者

I have a simple app that runs on the emulator, but now that i am trying to run it on a DroidX device it get Forced Closed messages immediately. The debugger logcat says it is "caused by: java.lang.ClassNOtFoundException: com.beam.Beam in loader dalvik.system.PathClassLoader{/data/app/com.beam..."

I have targeted SDKI7, with Min SDK version 7.

Im guessing that the app is either not loading into the device memory or eclipse can't find it in the device to run it.

Here's my Logcat message:

This is one step you can take - if you are using eclipse right click on your project and go to Android. Check the build target or change it to your Phones Platform. Also make sure that Debugging mode is ON on your phone. Hope this helps

i noticed the uppercase B on /data/app/com.Beam is it a mistype or did you copy paste it. Maybe its a casesensitive/windows/linux type of issue.

You could check if you spelled it somewhere with an uppercase B.
