I run to this error when trying to import FacebookSDK to android platform.

-compile:
[javac] Compiling 151 source files to /Users/duyduong/Dev/tns/lib/Android/FacebookAndroidSDK/bin/classes
[javac] warning: [options] source value 1.5 is obsolete and will be removed in a future release
[javac] warning: [options] target value 1.5 is obsolete and will be removed in a future release

[javac] final Set permissions = new HashSet<>();
[javac] ^

The FacebookSDK version is 4.1.2.

Hi @duongnhatduy
In order to set your version of JAVA to 1.7, you have to set your JAVA_HOME environment variable to point to you jdk 1.7:
Can you try this:

export JAVA_HOME=jdk-install-dir
export PATH=$JAVA_HOME/bin:$PATH

Hi @rosen-vladimirov ,
I have 1.8 on my mac os.
/System/Library/Frameworks/JavaVM.framework/Versions/Current/Commands/java -version
java version "1.8.0_40"
Java(TM) SE Runtime Environment (build 1.8.0_40-b27)

Does this problem relates to the compiler?

Hi @duongnhatduy ,
Can you send us the output of

echo $JAVA_HOME

[duongnhatduy]

@rosen-vladimirov
It is /Library/Java/JavaVirtualMachines/jdk1.8.0_40.jdk/Contents/Home

as @rosen-vladimirov said the JAVA_HOME should point to jdk folder:
JAVA_HOME=/user/folder/jdk
