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"

IVoiceCapture Get data return 0 on android , while capturing state is OK

With regard to this Bug UE-58340 , not sure if its related or not, but on Hawuii G8 , IVoiceCapture->GetCaptureState() return 0 and in the same time VoiceCapture>IsCapturing() is returing true , no errors from states at all, while on other devices works fine. I even tested it on another Hawuii G8 device with the same results , is it a low level bug inside engine related to hardware or what ?

I hope to get any answers from Community.

I was sure 100% from all permissions and .ini settings.
