React-native-push-notification: failed to post notification on channel null

[manuTro]

Hi,
when my app (android) is on background I cannot see the notification on the notification bar, but I can see the notification on the console and on my simulator I have

I'm using
react-native: 0.55.4
minSdkVersion 16
targetSdkVersion 26
and
com.google.gms:google-services:4.0.1.

I don't want to downgrade to targetSdkVersion 25 since, as Google says from August 2018 for new apps and November for app updates, you will be required to target Android O (API level 26)

I have the same problem.... since I had installed the react-native-fcm.
Can anyone help us?

[xainbutt]

I am also having this problem but i cannot see notification in any case, it just shows this error notification.

@manuTro can you share your code..

[manuTro]

@xainbutt my code is in clojurescript.. however here it is

(defonce app-root
  (r/create-class
   {:component-will-mount
    (fn []
      (let [width (aget (.get Dimensions "window") "width")]
        (dispatch [:width-scale width])
        (.configure PushNot
                    #js {:onNotification (fn [notification]
                                           (println "notification: " notification))
                         :onRegister (fn [token] (println "token-notification" token) (reset! tok token)

                                       (dispatch [:token-notification (.-token token)])
                                       (dispatch [:os (.-os token)]))
                         :senderID "......"
                         :requestPermissions true
                         :permissions #js {:alert true
                                           :badge true
                                           :sound true}})))
    :reagent-render
    (fn [] .......)}))

[Gp2mv3]

Can you try with the last git version of this package ?
Normally Oreo is now supported (using the code from this repo and not npm). We will have to upload a new release to npm.

[manuTro]

@Gp2mv3 I tried but I got this error
````

@Gp2mv3 I solved this error (and another one after this) by upgrading on react-native-push-notification/android/build.gradle this dependencies

def DEFAULT_COMPILE_SDK_VERSION = 26
def DEFAULT_BUILD_TOOLS_VERSION = "26.1.0"
def DEFAULT_TARGET_SDK_VERSION = 23
def DEFAULT_SUPPORT_LIB_VERSION = "26.1.0"
def DEFAULT_GOOGLE_PLAY_SERVICES_VERSION = "+"
def DEFAULT_FIREBASE_MESSAGING_VERSION = "+"

Now It is working fine on Android Oreo. I'll test if it works on Android 7

[manuTro]

@Gp2mv3 I've just tried with Android 7 and notification are not coming at all..

[VincenzoCarlino]

@manuTro I have yours same issue, can you share your build.gradle dependecies? thanks a lot

[VincenzoCarlino]

I'm sorry, I meant this file: react-native-push-notification/android/build.gradle

[manuTro]

With this changes it works with oreo but not with previous versions..

[manuTro]

@Vincenzo1997 did you find a solution?

[VincenzoCarlino]

Not yet , I'm able to make It work in Oreo 8.0, but not for previous sdk

Can you try with the example app ? I did it with Android 7.1.2 and it works perfectly. Same on Android 8.

[myrsapp]

Probably this is the problem
link: https://developer.android.com/guide/topics/ui/notifiers/notifications

[Gp2mv3]

Normally, using the npm package from the git repo, it's corrected. We are just waiting for an npm update.

[manuTro]

It's working. I tried again by importing the library writing on my package.json
"react-native-push-notification": "https://github.com/Dhanraj-bidchat/react-native-push-notification.git" (before I was just cloning the last repository on my node_modules.. I thought it was the same.. ) and by adding on my build.gradle

ext {
    googlePlayServicesVersion = "4.0.1" // default: "+"
    firebaseVersion = "+" // default: "+"


    // Other settings
    compileSdkVersion = 27 // default: 23
    buildToolsVersion = "23.0.1"
    targetSdkVersion = 26 // default: 23
    supportLibVersion = "26.1.0" // default: 23.1.1

Now It is all working fine. I tested it on Android 8 and Android 7. Thanks @Gp2mv3 !
