How Can my app know if android device has received a new message

Question

I am new to React-Naive and trying to build an app that sends message through app using react-native-get-sms-android .

I am able to send and read SMS from inbox but there is no Event in the package to know if a new sms has been received.

Is there any Event or API in react native for this? I think I will have to use polling to check if a new sms has arrived.

You can either create your own native module or use react-native-android-sms-listener to listen for the new messages similar to Whatsapp .

Manual Installation is provided in the docs

Usage

import SmsListener from 'react-native-android-sms-listener'

componentDidMount() {
  this.subscription = SmsListener.addListener(message => {
    console.info(message)
  })
}

componentWillUnmount() {
  this.subscription.remove()
}

where the contents are in the format

{
  originatingAddress: string,
  body: string
}

Also make sure that you need specific permissions to read SMS for android, check the permissions docs here
