Have you initialized FacebookSdk.sdkInitialize(getActivity().getApplicationContext()); ?
Did you try to do anything with this button in java code or did you just insert it and try to see if it shows up?
I belive you imported all the libraries?

after importing the extended calendar view for android into my android project, the xml file for my activity does not seem to load the extendedcalendarview into design view of my activity. After looking around, I found out that maybe I might have made a mistake importing the project, but I dont think that is the issue, as I believe I followed all of the correct steps. Here is the error:
Rendering Problems-
Rendering Problems The following classes could not be instantiated:
- com.tyczj.extendedcalendarview.ExtendedCalendarView (Open Class, Show Exception, Clear Cache)
Tip: Use View.isInEditMode() in your custom views to skip code or show sample data when shown in the IDE

Does anyone have an idea for this one?, the help is appreciated.
I am trying to create a tab layout with swipeable views. To add ViewPager I have created activity_fragments_logs.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent" android:layout_height="match_parent">
<android.support.v4.view.ViewPager xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent">
</android.support.v4.view.ViewPager>
</LinearLayout>
I have added Support Library by following the steps at https://developer.android.com/tools/support-library/setup.html
Now the design tab of this xml file is giving ClassNotFoundException. This is the exception:
