Finding What the Android Facebook SDK Version Is

Question

How do I find out the version of the current SDK is installed or referenced by my application? I have looked through the class files and the manifest but there is no reference as to what version it is.

Thanks in advance.

You have FacebookSdkVersion class with the current version: https://github.com/facebook/facebook-android-sdk/blob/master/facebook/src/com/facebook/FacebookSdkVersion.java

final class FacebookSdkVersion {     public static final String BUILD = "3.5.2";     public static final String MIGRATION_BUNDLE = "fbsdk:20130708"; } 

Since this class is without modifier and you can't access it from your package, use a reflection. This will return you the sdk version:

private String getFacebookSDKVersion() {     String sdkVersion = null;     ClassLoader classLoader = getClass().getClassLoader();     Class<?> cls;     try     {         cls = classLoader.loadClass("com.facebook.FacebookSdkVersion");         Field field = cls.getField("BUILD");         sdkVersion = String.valueOf(field.get(null));     }     catch (ClassNotFoundException e)     {         // error     }     catch (NoSuchFieldException e)     {         // error     }     catch (IllegalArgumentException e)     {         // error     }     catch (IllegalAccessException e)     {         // error     }     return sdkVersion; }
