Android + Facebook SDK : "Failed to authenticate the application because of app name mismatch."

Question

While trying to use Facebook SDK on my Android App, I got this error:

"Failed to authenticate the application because of app name mismatch. Please check the application name configured by the dialog."

After reading many posts on this subject, from other people getting the same issue and succeeded in correcting it, it's still impossible for me to get the Facebook SDK working… I suppose there is something wrong between the app configuration on Facebook and my Android project, but I don't understand what.

This is my application configuration on Facebook :

• App ID : 752068304844308
• Display name : TestFSdk
• namespace : lbptestfsdk

The configuration for Android on Facebook :

• Package name : fr.laposte.testfsdk
• Class name : fr.laposte.testfsdk.MainActivity
• Key hash : the one i get with key tool + openssl (android debug key)
• Single Sign On : yes
• Deep Linking : no

And my Android project :

• Eclipse project name : TestFSdk (is it important ?)
• Activity class using FB SDK : fr.laposte.testfsdk.MainActivity

• strings.xml contains :

  <string name="app_id">752068304844308</string>
  <string name="app_name">TestFSdk</string>     --> is it usefull ?
  

• AndroidManifest.xml :

  <?xml version="1.0" encoding="utf-8"?>
  <manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="fr.laposte.testfsdk"
      android:versionCode="1"
      android:versionName="1.0" >
      <uses-sdk
          android:minSdkVersion="8"
          android:targetSdkVersion="19" />
      <uses-permission android:name="android.permission.INTERNET" />
      <application
          android:allowBackup="true"
          android:icon="@drawable/ic_launcher"
          android:label="@string/app_name"
          android:theme="@style/AppTheme">
          <meta-data android:name="com.facebook.sdk.ApplicationId" android:value="@string/app_id"/>
          <activity
              android:name="fr.laposte.testfsdk.MainActivity"
              android:label="@string/app_name" >
              <intent-filter>
                  <action android:name="android.intent.action.MAIN" />
                  <category android:name="android.intent.category.LAUNCHER" />
              </intent-filter>
          </activity>
          <activity
              android:name="com.facebook.LoginActivity"
              android:theme="@android:style/Theme.Translucent.NoTitleBar"
              android:label="@string/app_name" />
      </application>
  </manifest>
  

Do you see something wrong ?

Thank you for your help.

Answer 1

According to documents https://developers.facebook.com/docs/android/share?locale=es_ES

and add

.setApplicationName("Display Name")

Answer 2

I had a similar issue. I was using SetApplicationName() in the ShareDialogBuilder to set a name that was different to the facebook Display Name. They must match!

Answer 3

Please check name in app(in your manifest file) and name of application on facebook().
