here log

 uploading file local path: c:\projects\myproj\app\build\outputs\apk\app-debug.apk remote path: /data/local/tmp/com.mycomp.myapp installing com.mycomp.myapp device shell command: pm install -r "/data/local/tmp/com.mycomp.myapp" pkg: /data/local/tmp/com.mycomp.myapp success 

so can see under setting ->application manager. not under apps on device.

all activities seem in test directory of project. please check in ide if not recognise directory default directory tests (would highlighted in green on project view), mean classes not compiled app.
