The following are commonly encountered problems and solutions for the Facebook Login for Android.

I get a login dialog error.

I get the native login dialog permissions, but the person is not authenticated. The logcat exception error returned looks like:

...W/fb4a:fb:OrcaServiceQueue(504): com.facebook.orca.protocol.base.ApiException: 
   remote_app_id does not match stored id


I see a non-native login dialog that includes an error that looks like:

...App is Misconfigured for facebook login...

If you are having trouble with your login dialog, here are some things to try:

My key hash is invalid.

If you are having trouble with your key hash, here are some things to try:

  • When you add a new key hash to the App Dashboard be sure to Save Changes.
  • The password you entered is incorrect. The default Keystore password: "android".
  • Copy and paste the key hash you sent to Facebook to the App Dashboard and Save Changes and make this change to onCreate() in your main activity:
    public void onCreate(Bundle savedInstanceState) {
         try {
             PackageInfo info = getPackageManager().getPackageInfo(
                               "{your-package-name}",                  //Insert your own package name.  
             for (Signature signature : info.signatures) {
                 MessageDigest md = MessageDigest.getInstance("SHA");
                 Log.d("KeyHash:", Base64.encodeToString(md.digest(), Base64.DEFAULT));
              } catch (NameNotFoundException e) {
              } catch (NoSuchAlgorithmException e) {

I get a Keytool error.

  • If you get a Command not found error, add the path to your global PATH or go to the folder to run the following command:
    On Windows: C:\Program Files (x86)\Java\jdk1.6.0\bin
    On MAC: /usr/bin
  • If Keytool could not find your debug.keystore location. Check for the correct path. Keytool always ask for a password when it has the correct location.
