java.lang.NoSuchMethodError on specific android device

[Sungyong An]

Currently, we are using `com.google.android.gms:play-services-ads:19.6.0`.

A number of crashes occurred today only on the specific Android device:
- Platform: Android 8.1.0

- NetworkType: Wi-Fi

- Locale: es

- Carrier: TIGO

- CountryCode: pa

So I wonder there is a known issue about this.
