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"

Android packaging failed

Hello, when I try to package my projet for Android (Shipping) I got an error and I do not know how to fix it. Here is the error log:

The error is porbably coming from ANT because of this line:

 UATHelper: Packaging (Android (Multi:ASTC,PVRTC,DXT,ATC,ETC2,ETC1)): C:\NVPACK\android-sdk-windows\tools\ant\build.xml:871: Can't read [C:\NVPACK\android-sdk-windows\platforms\android-24\android.jar] (Can't process class [dalvik/system/DexClassLoader.class] (Unsupported class version number [52.0] (maximum 51.0, Java 1.7)))

Cheers.

The issue was fixed by downgrading from JDK 8 to JDK 7 and changing CodeWorks suite from R5 to R4.
