Facebook android does not call callback function upon login #29

Ayame · 2013-03-12T22:00:23Z

I have a strange error with your plugin, the biggest problem being there are not errors generated.

The situation is as follows:

When the user clicks login in my application, I call the FB.login() function and he is redirected to either the facebook app if installed or the web browser if not installed
When using the web browser to login, everything works fine, user credentials are returned and the app usage can continue
When the user has the facebook app installed however, after providing credentials the app switches back to my app, but does not call the callback function for the login. It's as if nothing happens.

The other odd thing is that the code I use works on iOS in both cases.

The code I use:

FB.login(
function(response) { console.log("RESPONSE FROM LOGIN");
if (response.authResponse) {
// some code here
} else {
alert('An error has occurred');
}
},
{ scope: "email" }
);

before this I call:

FB.init({ appId: myappid, status: true,
cookie: true,
xfbml: true,
oauth: true,
nativeInterface: CDV.FB,
useCachedDialogs: false
});

The logger returns:
03-12 22:51:28.470: D/CordovaLog(21023): Cordova Facebook Connect plugin initialized successfully.
03-12 22:51:28.470: D/CordovaLog(21023): : Line 1192040477 : Cordova Facebook Connect plugin initialized successfully.

All I get from the moment I call the FB.login() function until it returns me to the app is:
03-12 22:58:45.170: D/DroidGap(21023): Paused the application!
03-12 22:58:45.170: D/CordovaWebView(21023): Handle the pause

03-12 22:58:49.715: D/CordovaWebView(21023): >>> loadUrlNow()

I'm really puzzled with this issue as it does work in the web view and on iOS; I would like to keep the source the same for iOS and android so I hope someone can help me resolve this issue.

Thanks!

Perhaps a follow up on this with an isolated example: I get the same problem with the sample "Simple" application.

I work with cordova 2.1.0 so according to the docs it should work. It appears that the FB.login() callback function is never called. I see the "will login" console.log, but not the "RESPONSE" console.log when the app uses the native FB app to connect on the system.
I have tested this on several devices with different android versions and keep getting the same result.

Any help would be wonderful.

For the sake of reference I have pasted the code below. Naturally I have replaced the appid with myappid here, please replace it with yours.

I had this same problem (callback not being triggered) when trying to login using the Facebook app. In my case the problem was the key hash I've generated with Java's keytool (I was using a wrong version of openssl). I used the instructions in this link to generate the correct key hash: http://stackoverflow.com/a/6665263
