The answer from the poster below is more succinct:

Context context = (Context) AndroidAppHelper.currentApplication();

An alternative hack is to retrieve the current activity (which can be cast to Context) like this:

Class instrumentation = XposedHelpers.findClass(
                "android.app.Instrumentation", lpparam.classLoader);

XposedBridge.hookAllMethods(instrumentation, "newActivity", new XC_MethodHook() {

                @Override
                protected void afterHookedMethod(MethodHookParam param) throws Throwable {

                    mCurrentActivity = (Activity) param.getResult();

                    Log.v(TAG, "Current Activity : " + mCurrentActivity.getClass().getName());
                }
});

Regarding the class loader, if it consists of the main app classloader then you can retrieve it from LoadPackageParam passed to the handleLoadPackage method.

If the app itself creates a new DexClassLoader then you can hook the DexClassLoader constructor to keep a reference to it. That way you have the actual ClassLoader that contains your class and method. No need to get any context.
