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"

Augmented Reality crashing on Android

I have opened the AR template and made no changes to the template at all. When I get the app packaged and installed on the device (Samsung S8) the app crashes on the Unreal logo and will not open.

I have had trouble compiling with Gradle but when using Ant it works fine. Other Android Apps build and open fine, just the AR does not work. I have ARCore installed on my phone and have the plugins configured in the project.

This seems to be a common problem for people but no straight forward answer seems apparent. Is there a problem with AR template?

Product Version: UE 4.21

Hello, I have the exact same problem:

The app crashes on android either instantly or shortly after the splash screen is shown:

  1. I have tried various versions: 4.20-4.22. Note that 4.19 does work for me! But the problem is the AR Core plugin in there is a really early one, there is no image recognition (augmented images) for example.

  2. I have tried various Samsung devices (S7 and Tab S3) the same result.

  3. I tried reinstalling NV pack, nothing

  4. Tried the UE4 source version forked by Google that is on their github repo, same result.

By the way I also could not deploy with Gradle, it keeps moaning about not having accepted all SDK licences, which is not true. I also used Ant.

I obtained the logcat and it says "UnsatisfiedLinkError: dlopen failed: library "libarcore_sdk_c.so" not found.

Have you checked your logs?

I have wasted 10 hours looking for a solution, would be pretty neat if somebody had an idea.

I had the same problem. I found that if you have Unreal Studio plug in activated can get trouble on android package. Worked for me.
