Crash After Login second time

[cafeasia3]

I am using ionic v1, when user login first time its fine, the facebook doesnt ask email and pass it shows popup then its logged in, then I logout using

facebookConnectPlugin.logout(function(){
	          $ionicLoading.hide();
	        });

then when I login again, this time the popup asked email and password, then my ionic app is crashed after log in. facebookConnectPlugin.getLoginStatus(function(response) this status return unknown

any idea whats wrong?

[cafeasia3]

yes, it returned OK, but the second login crash the ionic app.

any work around this? or just dont need to logout the facebook?

Has anyone managed to solve this problem?

@andevit Hi, my PR fixes the crash. I haven't seen any side effects so far, but I'd appreciate @jeduan or someone else checking it.

if the getLoginStatus return unknown you have to login again before doing anything

 this.facebook.getLoginStatus().then((success) => {
        if (success.status === 'connected') {
             // cool
        } else {
            this.facebook.login(['public_profile']).then((response) => {
                 // cool
            }, (error) => {
                 // damn
            });
        }
    }, (error) => {
          // damn
    });

could you give a try @cafeasia3 ?

@peterpeterparker it's still crash. Can not login again with Facebook after logout. when i try to login second time it return "undefined" and try to login again it crash. Any solution.

@A110SHT

there is a lack of details in your question, sorry but I can't give an answer based on "it crash". which os? which os version? which version of the plugin? and important how does your code looks like? could you provide a sample repo? what's the stacktrace? etc.

you could try your luck with the PR #642 if you wish (note: I personally don't plan to merge it, maybe other maintainers will)

@peterpeterparker sorry for incomplete question. I try on Android v - 5.1.1. my code look like this
``$(document).on('click', '#facebook', function () {
login = 'fb';
var facebook = facebookConnectPlugin.getLoginStatus();
if (facebook === undefined) {
loginWithFB();
}
else if (facebook.status === 'connected') {
console.log(facebook);
}
});
function loginWithFB() {
facebookConnectPlugin.login(["public_profile", "email"], function (result) {
facebookConnectPlugin.api("/me?fields=email,name,picture",
["public_profile", "email"]
, function (userData) {
console.log(userData);
feedbackTabs.FacebookLogin(userData)
}, function (error) {
console.log(error);
notification("Cannot login from facebook", null, "Login", Ok);
});
}, function (error) {
console.log(error);
notification("Cannot login from facebook", null, "Login", Ok);
});
}

@A110SHT spontaneously I would say that the first error is in your code, getLoginStatus return a promise (see my above code example). But to me it then looks like a support inquiry, so plz use channels like Stackoverflow or Ionic forum to solve your issue, thx in advance

[peterpeterparker]

Finally @joaquinr submitted a sample repo on the Ionic Forum (https://forum.ionicframework.com/t/unable-to-install-cordova-facebook-4-plugin-with-android-7-0-0/118170/8) and therefore I was able to reproduce the problem of app crashing after a second login on Android

I solved the issue with following commit b594d32

This patch v2.0.1 is now released and available in npm, therefore I close this issue

After a long time, finally got a superb solution.
Thanks @peterpeterparker for your help.

Please check if you have not done yet the following process

1. cordova plugin rm cordova-plugin-facebook4
2. npm uninstall cordova-plugin-facebook4
3. cordova plugin add cordova-plugin-facebook4@2.1.0 --save --variable APP_ID="*********" --variable APP_NAME="your app name"
4. npm install cordova-plugin-facebook4
5. cordova platform rm android
6. cordova platform add android (7.0.0)

It's working fine now. Please try.
