android-remote-notifications

A Google GCM/Amazon SNS alternative using pull instead of push.

Main features

Independent user notifications (no Google GCM or Amazon SNS), just put a JSON file in the cloud
Framework will update available notifications automatically in defined time intervals (now, daily, weekly, bi-weekly, monthly)
Flexible parameters:
- start date for notification (distribute early, show later)
- amount of times the notification should be shown
- interval between showing notifications (always, every day, every week, every month)
- specify on which app version (versionCode) the notification should be shown
Show notifications as AlertDialog or Toast message (defined by the remote JSON file)
- AlertDialog: Specify button captions and actions: Open Store-Action, Open URL-Action, Exit App-Action, all defined by a JSON file on your server
perfect to inform your users about discounts on one of your other apps or premium version
pro tip: as some users don't always update to the latest app versions you should integrate this framework in an early phase if you plan to use it at a later time.

How to integrate

You can find the source code of the example app here: MainActivity

The easy way

Call RemoteNotifications.start(context, url, UpdatePolicy.NOW); in your onCreate() or onResume() method

this will

start an update of the notifications (use UpdatePolicy.WEEKLY in production environment to update once a week)
show due notifications to the user

For more control

RemoteNotifications rn = new RemoteNotifications(context, url);
rn.updateNotifications(UpdatePolicy.NOW);
rn.showNotifications(); // if update still runs, event will be queued and carried out later

// -or, register a listener on update completion-
rn.updateNotifications(UpdatePolicy.NOW, finishListener);

How to build a JSON notification file

First: You don´t have to write the JSON file by hand. Just use the API to initialize a Notification object and then create JSON from it: NotificationCreatorUtil

Example of a Toast Notification

[
  {
    "type": "ToastNotification",
    "notificationConfiguration": {
      "startShowingDate": null,
      "executionPolicy": "ALWAYS",
      "numberOfTotalViews": null,
      "versionCodePolicy": null
    },
    "message": "This is a Toast Notification",
    "duration": 1
  }
]

Example of an AlertDialog Notification

[
  {
    "type": "AlertDialogNotification",
    "notificationConfiguration": {
      "startShowingDate": null,
      "executionPolicy": "ALWAYS",
      "numberOfTotalViews": null,
      "versionCodePolicy": null
    },
    "title": "Title",
    "message": "This is an AlertDialog notification",
    "negativeButtonText": "Exit App",
    "neutralButtonText": "Open web page",
    "positiveButtonText": "Open Play Store",
    "positiveButtonAction": {
      "type": "OpenStoreButtonAction",
      "packageName": "de.vorlesungsfrei.taekwondo.ads"
    },
    "negativeButtonAction": {
      "type": "ExitAppButtonAction"
    },
    "neutralButtonAction": {
      "type": "OpenUrlButtonAction",
      "link": "https://github.com/kaiwinter/android-remote-notifications"
