Build Daydream app error major version 52 is newer than 51

[Chris Babcock]

Use jdk1.8.0 instead of jdk1.7.0. After you do this, you may see java 1.5 obsolete warnings, but you can ignore these. I also recommend undating Proguard to a version that works with the android-24 jar. Follow these instructions: https://forums.unrealengine.com/show...l=1#post666806

Tried to download the Java SDK 1.18, and updated the Java SDK location in project setting, doesn't help

I'm running on Unreal Windows and want to build a daydream app for android, cannot build it....

Noticed one line, how should I solve this problem? what does the compiler mean in this place? Thanks guys!
