Default [Q] Galaxy Tab 3 7.0 Debugging issue

I'm having a problem running apps that I developed inside eclipse onto Galaxy Tab 3 (SM-T210) 4.1.2. Whenever I run the app, the device list shows up saying that the tablet it online and everything seems fine, but the application doesn't show up on the device anywhere. I've successfully been able to run and test apps using my Galaxy SIII running kitkat 4.4.3 and even the android device emulator. I've tried switching the target API and updating the sdk but still no luck.. Any solutions?
