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"

Please make sure that you've deleted your Intermediate and Saved files. I would also suggest checking with a new, blank template and seeing whether or not you're able to package for Android. Verify that you can launch onto an Android device. After you've checked all of that, I would also test with 4.13.1 and see if you're still having the issue with your project.

Thank you!
