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"

Meybe these information could help to solve this problem?

Packing for Win (32&64) works great. Copy my stuff to a new project even do not solve this problem. Visual Studio is installed and runs. I tryed Version 4.11 and 4.12 from the Epic Game Installer. I did not had this Problem two Weeks before I installed the 4.12.

Best regards BobKing23

After the update to 4.12.1 I tried it again with a new project, but no chance.

  • Are you using a Binary or Source version of the engine?

  • Can I see your Android SDK Settings?

  • Can you package all other platforms?

  • Can you launch onto your device?

Do you have everything installed for UE4 if you're on the Binary version? If you're not sure, you can check by pressing the black arrow beside launch from the launcher and clicking on options. Select everything and apply the changes.

Looking forward to hearing back from you, thanks!

Hello Ms. Sutton,

thanks for your reply.

  • List item I'm using the binary I think.

  • List item The SDK Settings are in the Screenshots below. I wonder why there are no locations in the SDK...

  • List item I only use Android and Win64 so long - Win64 worked after I turned off some plugins in 4.11.2. In 4.12 and 4.12.1 from start up no problems with this.

  • List item I can't launch it on my mobile device (LG V10)

Thank you BobKing23
