1. Get UE4 from GitHub
2. Unzip the ZIP into the directory containing Engine (it should write over old UElibPNG.Build.cs and add libPNG-1.5.27 and BuildForAndroid.bat)
3. Compile UE4 as normal, then your project
4. Package as normal for shipping and upload to Google

BuildForAndroid.bat uses the NDK to compile libpng libs for the 4 architectures. These are already included in the ZIP so you should skip running it.

Thank you so much! It’s WORK!!!
