java.lang.NoClassDefFoundError: java.nio.charset.StandardCharsets in Android API < 19

We have been a long time with an old version of your library. Now, we have upgraded to the latest version and the library crashes on all the devices we have with API 16, 17 and 18. We have also tested your test app and it crashes as well.
The problem is in the org.eclipse.paho.client.mqttv3 library version. Version 1.2.1 and higher do not seem to support API < 19, because they use StandarCharsets and StandarCharsets was added in API 19.
For now we have fixed it by forcing the library version in our build.gradle, while we hope you can release a new version with the problem fixed.
implementation('org.eclipse.paho:org.eclipse.paho.client.mqttv3') { version { strictly '1.2.0' } }
