Q:

Uploaded an Application to the play store but it won't open

So I recently uploaded my Android application to the Google Play store and it published successfully. This is the application here: https://play.google.com/store/apps/details?id=com.kyoudai.sudioku
The problem is, when anyone installs thiis application, they cannot open it i.e. the open option does not appear on the playstore, only the uninstall option. This application also cannot be found in the application drawer on any device, or in the list of installed applications. I've tried editing my manifest and included everything necessary but I have no idea why this happens. I generally believe if there was an issue with my code that should not be possible for an android application, the play store would flag it. When I was developing this, it showed up on the emulator application drawer so I assumed it was fine. I'm not sure why this happens, and I'm not even sure where to contact google regarding this. Any help is appreciated.
Given people are gonna jump on the manifest configuration, here it is: https://github.com/BerserkerLan/Sudoku-Android/blob/master/app/src/main/AndroidManifest.xml

So basically, the issue was that I just had too many category elements in my intent-filter and thus somehow that was interfering with the MAIN, VIEW and LAUNCHER elements, so now I only have those three in it and it launches fine.
