04-17 15:15:47.140: E/Facebook(14515): Error: com.facebook.FacebookException: Failed to     
authenticate the application because of app name mismatch.  Please check the application   
name configured by the dialog.

Answer 1

Go to Facebook developers page

Apps --> "YourApp" --> settings -->

Then change Package name (your application package name) and Class name (your activity class name)

for an example:

Answer 2

This error is occuring due to mismatch of name, may be package name or class name or even application ID.

You need to check the AndroidMainfest.xml and also the dashboard of https://developers.facebook.com/apps/yourAppID/settings/. On the xml check if this is same as on the dashboard

<meta-data
        android:name="com.facebook.sdk.ApplicationId"
        android:value="app_id" />   //the app_id must be same as on the dashboard

    <activity android:name="com.facebook.LoginActivity" >
    </activity>

Also check for the package name, class name of the dashboard is same on your android app.
