Troubleshooting

In this page you'll learn what are the most common mistakes when implementing the Notificare library for Android.

Misplaced App Keys

When implementing Notificare, the library configuration file (located at /assets/notificareconfig.properties) must contain the Application Key and the Application Secret. In Google Cloud Messaging/Firebase Cloud Messaging there is no separation between development and production environment so you don't necessarily need to create applications in Notificare for both environment, although we strongly recommend that you have a an application for each environment. Please read more about configuration file here.

GCM/FCM Errors

A very common mistake it to confuse the SenderID with Server Key. There's a clear distiction between the two. They both can be found in the Firebase's Developer Console, like shown here. The SenderID is included in the google-services.json file added by Firebase to your app like explained here. The Server Key is generated by Firebase and uploaded to Notificare, like shown here. This will enable our platform to send notifications to your app.

Missing Dependencies / Permissions

One of the most common mistakes when implementing Notificare are missing permissions in your AndroidManifest.xml file. Some of these permissions are required for the library to work. In most cases this will originate crashes when building your application. Necessary permissions are automatically added by the various Notificare modules, so make sure you include all the dependencies your application will need. You can read more about the dependencies here.

Missing Notification Channel

For Android 8 (Oreo) and above, your app needs at least one notification channel to display notifications. Please follow instructions here.

Fingerprints in HMS AppGallery

For HMS to work it is important to set the necessary SHA-256 fingerprints for any environment that you will run the app in, including any development machine that you wanna run a debug build from. These fingerprints can be found in your debug.keystore:

/> keytool -list -v -keystore ~/.android/debug.keystore

You can read more about setting up HMS here.

Google Maps key in Android

Notificare will require access to the Android Maps API in order to display Google Maps. These maps can be included in the content of a notification. Most common mistake when using Android Maps is to forget to get access to the API and to generate an Android Key. You can read more about creating an Android Maps V2 Key, here.
