As per my experience, you need to create a custom plugin and use your .aar file in your custom plugin.
Follow the below steps to use ur .aar file in Ionic project.
Step 1: Create a plugin.
You can use Plugman to create your custom plugin.
Step 2: Setup All Android dependencies
Setup all required dependency for your .aar file to support native dependencies through Gradle.
Step 3: Configure APIs
Need to define required wrapper API in your .JS file which is exported to the Cordova application.
By these 3 steps, you will get your .aar functionality through custom plugin wrapper and expose all required methods for Ionic app.
