App cannot be launched, but seems to have installed

Question

I changed the manifest of my app, and now the app cannot be launched. No icon. However, when I check installed under setting Application Manager, I see it there! Whats going on??? I have used same permissions before. I just changed which app was MAIN and launcher. Now cannot see the app. Does not come up via Studio or show up in Apps device!!!!

Update: created new app with same permissions and launches ok, so it does not really seem to be permissions ...

 Installing com.mycomp.myapp
DEVICE SHELL COMMAND: pm install -r "/data/local/tmp/com.mycomp.myapp"
pkg: /data/local/tmp/com.myapp.
Success

Here is 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 now I can see it under Setting ->Application Manager. But not under Apps on the device.

Answer 1

Make sure that you delete app from device properly: go to Settings -> Applications. If you find your app here then choose it and make "delete for all users" in setting menu. After that try to inslall your app again.

Answer 2

All your activities seem to be in the test directory of your project. Please check in your IDE if it does not recognise this directory as a default directory for tests (would be highlighted in green on the Project view), as it would mean that the classes will NOT be compiled into the app.
