Public Methods

public abstract Task<Void> startSmsRetriever ()

Starts SmsRetriever, which waits for a matching SMS message until timeout (5 minutes). The matching SMS message will be sent via a Broadcast Intent with action SMS_RETRIEVED_ACTION. The Intent contains Extras with keys EXTRA_SMS_MESSAGE for the retrieved SMS message as a String, and EXTRA_STATUS for Status to indicate SUCCESS, DEVELOPER_ERROR, ERROR, or TIMEOUT.

Note: Add SEND_PERMISSION while registering the receiver to detect that the broadcast intent is from the SMS Retriever. Be aware that this detection only works on devices using Google Play services v19.8.31 and later.

The possible causes for errors are:

  • DEVELOPER_ERROR: the caller app has incorrect number of certificates. Only one certificate is allowed.
