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"

This is with a build of 4.7.0 preview 7 on Tegra K1 hardware, compiled from source. The ES2 build is fine.

So far I haven't reproduced this crash on a Shield Tablet, using the same build of source (4.7 preview 6 from Github).

A couple things:

  • Can you reproduce this using a free UE4 project from the marketplace? Or provide a sample of your crashing project.

  • Can you give more info on your hardware?

  • Most importantly, what investigations have you already tried? If you remove certain features or content from the package (loading movies?) can you figure out a workaround to isolate the issue?

Many thanks

Are there any errors in the log before that crash?

Did you compile the ES31 binaries using the bBuildForES31=True and bBuildForES2=False .ini settings? Also, use separate APKs so that the ES31 executable is the only one in the APK.
