onesignal-push-icon

Automatic android push icon generation for the OneSignal push notification platform as described here: Android Notification Icons

Create an icon in the root folder of your project and use onesignal-push-icon to automatically resize and copy it for the android platform and the SDK you are using.

Installation

$ sudo apt-get install imagemagick
$ # on Mac: brew install imagemagick 
$ # on Windows: http://www.imagemagick.org/script/binary-releases.php#windows (check "Legacy tools") 
 
$ sudo npm install onesignal-push-icon -g

Requirements

• ImageMagick installed

Usage

Create a push.png file in the root folder of your project.

To create the push icons for android native run:

 $ onesignal-cordova-icon

The different sizes of the push notification will then be created with the appropriate paths and filenames.

You also can specify an SDK or a location for the icon file manually:

 $ onesignal-cordova-icon --sdk=cordova --icon=mypush.png

Available values for the--sdk option:

    --sdk=native    Android Native (default)
    --sdk=unity     Unity
    --sdk=cordova   PhoneGap, Cordova, Ionic
    --sdk=ionic     Ionic Package (Cloud Build)
    --sdk=phonegap  PhoneGap Build (PGB)
    --sdk=corona    Corona
    --sdk=xamarin   Xamarin

For good results, your file should be:

• square
• at least 96*96 (512*512px recommended to be future-proof)

Note: Android 5.0+ enforces your icon to only be white and transparent however it still allows tinting on the notification shown in the shade, known as the "accent color" (see Small Icon Accent Color).

Creating a cordova-cli hook

Since the execution of cordova-icon is pretty fast, you can add it as a cordova-cli hook to execute before every build. To create a new hook, go to your cordova project and run:

$ mkdir hooks/after_prepare
$ vi hooks/after_prepare/onesignal-cordova-icon.sh

Paste the following into the hook script:

#!/bin/bash
onesignal-cordova-icon

Then give the script +x permission:

$ chmod +x hooks/after_prepare/onesignal-cordova-icon.sh

That's it. Now every time you cordova build, the icons will be auto generated.
