title: Facebook SDK instruction not making sense about app id
body: <p>I have taken a picture of the Facebook instruction below. What is wrong with it? My app keeps crashing with exception concerning ApplicationId should not be null. But I have added my app id as <code>&lt;meta-data android:name="com.facebook.sdk.ApplicationId" android:value="@string/facebook_app_id"/&gt;</code> in the manifest; that is after adding it as a string in the <code>strings.xml</code> resource as <code>&lt;string name="facebook_app_id"&gt;0000000000&lt;/string&gt;</code></p>
  
  <p>So I figure the instructions is wrong because it does not say which <code>uses-permission</code> to add and it says to call the string resource key <code>com.facebook.sdk.ApplicationId</code> with value <code>Facebook_app_id</code>.
