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"

HI SalihBalkan,

  • Does this occur in a clean, blank project with no additional content or is it limited to one project?

  • What steps can I take to reproduce this on my end?

  • Is this limited to a specific device?

  • Are you launching or packaging to the Android device?

Hi everyone,

I was able to reproduce this on my end, however upon further inspection it looks like this is a known issue. You can view this issue here. Additionally, I'm happy to report that the error has been fixed and should be available in 4.13.

I want to report the same issue.

I have done a widget with a text box, like a password, I write a word and I get an action. I play it with mobile preview on PC and it works. It gets the text changed and it plays an action.

Then I play on the android device (packaged) and it can't get the text, so, I can write the word, but it happens nothing.

the Xperia J is below the specs we can support with UE4. Do you have another phone available to test on?

Yes, but I think that's not the problem. Why can I launch the app on Xperia J, but not to run this specific blueprint?

many of the rendering features require a stronger CPU and GPU than what the Xperia J has available. As such, many features will most likely not render or will not correctly render on this device. This is why, if you have another phone available, it would be best to test on a stronger phone, such as a galaxy s4, to see if the error reproduces on phones that can definitely handle UE4 applications.

Same problem with Zenfone 5 A501CG

I have checked with Samsung Galaxy Note 4, and it remains the problem.
