LibGDX Android project not running properly

Hey, so I’ve been doing LibGDX stuff for a little while now and I wanted to start Android development, so I got an SDK and configured Eclipse and everything. Whenever I run my Android project with an actual plugged-in device, the device doesn’t show up in Eclipse’s listing. Whenever I try to run on an AVD, I just get the never-ending Android splash screen or black screen. After I close the failed program, I get this in the console:


[2015-05-10 21:43:08 - AndroidTest-android] Installing AndroidTest-android.apk...
[2015-05-10 21:43:57 - AndroidTest-android] Installation error: Unknown failure

[2015-05-10 21:43:57 - AndroidTest-android] Launch canceled!

Any idea of what that means? How do I check the logcat?
