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?

Android Extendedcalendarview Resource Not Found Error

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:

Android Studio seems to want to use the N Preview renderer if you have the N SDK installed. Use the dropdown to select a stable version.

ClassNotFoundException - android.support.v4.view.ViewPager

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:
