`implementation 'com.hbb20:ccp:2.3.7'`

```

```
and in `onCreate()` method `ccp.registerCarrierNumberEditText(etPhoneNumber);`

Start with InternationalPhoneTextWatcher.java at line 168, where the stack trace shows the selection update failing during afterTextChanged. Reproduce the crash using CountryCodePicker 2.3.7, ccp_autoFormatNumber="true", and registerCarrierNumberEditText(etPhoneNumber). Done means entering the reported phone input no longer causes the IndexOutOfBoundsException.
