    Unclear why you are using JDBC on Android. See: [JDBC vs Web Service for Android](https://stackoverflow.com/q/15853367/295004) – Morrison Chang Oct 08 '19 at 15:42

The reason is MySQL driver has a dependency on protobuf library. See the compile dependency section here

Instead of adding lib from your local, use the following.

// https://mvnrepository.com/artifact/mysql/mysql-connector-java
compile group: 'mysql', name: 'mysql-connector-java', version: '8.0.17'

Leaving that aside, please use an API layer instead of JDBC on DB. You are welcome.
