Implement BOOT_COMPLETED receiver.  NOTE:  You must manually add the android permission android.permission.RECEIVE_BOOT_COMPLETED to your AndroidManifest -- the plugin has this element in its plugin.xml purposely commented-out.  Also, when the BackgroundGeolocationService is run due to a BOOT_COMPLETED, there's no way to fetch any kind of user info, such as an authentication_token for your server to authenticate an HTTP request (if you've enabled the HTTP feature).  However, the HTTP request will insert the Android UUID which you *can* use to authenticate the request.  It's up to the developer to map the Android UUID to some particular user on your server.  You may fetch the Android UUID using the standard cordova plugin org.apache.cordova.device (see the documentation there on that API)

Http service

Re-implement android background-service.  Migrate control out of the CordovaPlugin and into BackgroundGeolocationService.  This is required for those who may still wish to have the plugin transmit locations to server via HTTP.  Re-implement HTTP layer with same options as free plugin (namely url, params, headers).  There is no persistence layer currently, so when in-plugin HTTP is enabled, the plugin won't re-try when no network is detected.
