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"

Using JNI interface in Android, missing jni.h

In my effort to use a aar Android library from Unreal game, I stumbled into odd problem.

When I try to include JNI class into my own JNI wrapper class

     ... 
     #if USE_ANDROID_JNI
     #include <jni.h>
     ... 

the editor/android launch compiler simply tells that "Can not open include file 'jni.h: No such file or directory".

So... I am doing something wrong here. Is there some inc path parameter somewhere in UE settings or what?

This is my 1st Unreal project :)

Answering my own question: Pressing "compile" in editor does not seem to make a Target Android compile, but a Windows compile, and there is no jni.h available for Windows compile, thus fail. At least I think so.

Launch to Android device succeeds.Even Play in editor works. Only Compile fails.

Add #if PLATFORM_ANDROID around that include.
