@evollu in release build getting same issues after install the apk the app dont get token it giving null and then after relaunch the app getting token is there any other thing to do or am i doing wrong any thing, because in debug build its working perfectly fine. Please help

[evollu]

it takes a while to get firebase token. i wonder if it could be a firebase bug

[Seemapadiya]

Okk but now what should I do to handle this condition , can you please help me out

[evollu]

listen on FCM.on('FCMTokenRefreshed', token => { and call FCM.getFcmToken on app start. The token should be there eventually. You can save the token in storage for future compare to see if it actually changed

[Seemapadiya]

Ok i will try it and let you know if its works or not, Thank you for help

[Seemapadiya]

@evollu Thank you very much, its working fine in release build.

@Seemapadiya I am facing the same issue. Could you please share code snippet?

[Seemapadiya]

@Udbhav12 previously i was used this method on my app start and its working fine in debug FCM.getFCMToken().then(token => { console.log("FCM >>>token>>" + token) }); For the release build issues i have to implement this method on app start and saved token in storage FCM.on('FCMTokenRefreshed', token => { console.log('FCMTokenRefreshed',token); }); if we didn't find token in FCM.on method but i have always get token in this method FCM.on('FCMTokenRefreshed', token => {})

@Seemapadiya Did you save parameter token in FCM.on('FCMTokenRefreshed', token => {}) and FCM.getFCMToken() to store?

Example:

FCM.on('FCMTokenRefreshed', token => {
    AsyncStorage.setItem('NOTIFICATION_TOKEN', token);
});

FCM.getFCMToken().then(token => {
   AsyncStorage.setItem('NOTIFICATION_TOKEN', token);
});

[Seemapadiya]

Yes direct store in to my model class
