Change JDK to 1.7 for Android packaging

[anonymous_user_e281dc471]

Hi,
I wanted to add the newest Facebook SDK to my Android game but when packaging I see following error:

E:\Biblioteka\Dokumenty\Unreal Projects\gameDNAstudio\ChasingRobbers\Intermediate\Android\APK\JavaLibs\facebook\src\com\facebook\AccessToken.java:559: error: diamond operator is not supported in -source 1.5
MainFrameActions: Packaging (Android (All)): UnrealBuildTool: [javac] ArrayList<String> permissionsList = new ArrayList<>();
MainFrameActions: Packaging (Android (All)): UnrealBuildTool: [javac] ^
MainFrameActions: Packaging (Android (All)): UnrealBuildTool: [javac] (use -source 7 or higher to enable diamond operator)

It’s happened because of wrong JDK version (1.6 instead of 1.7). I’ve installed JDK 1.7 but this error still occurs.

Could you help me?

Hi did you find a reply to this, I would also like to know how to change this?

AndroidWorks in 4.9 installs JDK 1.7, but you can also change the line to ArrayList<String> permissionsList = new ArrayList<String>(); since <> is a shortcut to do this.

If you don’t want to make the changes and have JDK 1.7, you will also need to add an ant.properties file containing:

java.source=7
java.target=7

You can place this in Engine/Build/Android/Java for all projects or in your project’s Build/Android directory.
