Troubleshoot

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

or,

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:

• If you don't have openssl, install it for Windows or MAC.
• Be sure you have signed your Android app.

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:

  @Override
  
  public void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
                  
       try {
           PackageInfo info = getPackageManager().getPackageInfo(
                             "{your-package-name}",                  //Insert your own package name.  
                              PackageManager.GET_SIGNATURES);
           for (Signature signature : info.signatures) {
               MessageDigest md = MessageDigest.getInstance("SHA");
               md.update(signature.toByteArray());
               Log.d("KeyHash:", Base64.encodeToString(md.digest(), Base64.DEFAULT));
               }
            } catch (NameNotFoundException e) {
                    
            } catch (NoSuchAlgorithmException e) {
                    
            }
             ...

• Generate a new key hash

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.
