ok so I went to setting and made sure that unknow Sources is on. However it still not showing up on the AVD manger and I guss i should tell you guys i have a pc.

On your phone ensure the following is checked: Settings→Applications→Unknown sources

Download and install the Android SDK and run:

adb -d install "the_name_of_apk"

If you haven't signed your app then you need to enable untrusted apps.

From the home screen press the menu button then

Settings->Applications->Unknown Sources

That should allow you to install your application
