Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Signed APK doesn't work 4.8.3 - black screen and no app icone on the desktop


I'm trying to send my build to other friends. Packaging my game without distribution enabled works fine on my phone. But when I send this apk to others phones, it doesn't work (crash on black screen).

So I've signed my game with keystool and packaged it in ETC2 and distribution mode enabled and pakage all in .apk. The build success and the file is now about 211mo.

But, when I install it on my phone, the app doesn't appear on the desktop of my phone, and (when I launch it after intall) it crash (black screen then launch Samsung gear store).

So I have few questions:

  • Is it necessary to sign a build to install it on others phones?

  • Why it works well when not distribution mode is enabled and crash when it's enabled?

  • Is packaging all in one apk (no obb) is the good way for Note 4 phone or S6?

I'm not trying to publish the game through store but just wanted to share it to friends and other developpers.

Thanks if you can help me

Same problem! Though it hasn't been answered in 4 and 1/2 months, so probably no fix yet? I just want to get a signed alpha test for gear vr sent to some people that doesn't show a black screen and then auto load the samsung gearvr app.

By the way Roonan, you can always download the not distributed app on your friends phone if you setup theirs for development and give them an osig. That is what I have done for my local friends, but they have to setup their own phones and install the batch from dropbox if they aren't local.
