I tried to build my project for android with the latest Unity 5.4.0f3. After I import the newest Facebook Unity SDK, it cannot be built anymore and throws this error :

Failed to compile resources with the
following parameters:
-bootclasspath “/Users/jing/Library/Android/sdk/platforms/android-24/android.jar”
-d “/Users/jing/Documents/Git/HexCrash/HexCrash/Temp/StagingArea/bin/classes”

UnityEditor.HostView:OnGUI()

I know this one must be some conflicts among android native jar files but have no idea how to fix it. Does anyone know how to fix this?

I just solved the problem myself. I updated my android sdk and jdk to the latest ones (25.1.7 and 8u102), and after this, build, made it.

Hope this can help someone~
