Answer 2

At this moment, your app wants you to login by:

• either redirecting you to the Facebook App if the latest is installed,
• or to this actual screen (which shouldn't be blank) if you don't have the Facebook App.

My first guess is that your app can't access to the Internet. Can you make sure you've got this line in your Manifest.xml?

<uses-permission android:name="android.permission.INTERNET"/>

Can you make sure that you successfully entered the Native Android App information in your app settings:

Moreover, did you:

• set <string name="app_id">41234567890</string> in your res/values/strings.xml ,
• and <meta-data android:name="com.facebook.sdk.ApplicationId" android:value="@string/app_id"/> in the AndroidManifest.xml ?

Could you also check that you followed each step of this tutorial .
