Google cloud translate API crashing for Android API level 19 or lower

My Android App works fine on API level greater than 19. But when i run my app on API level 19 or lower, i crashes while opening. I tried removing Libraries from the gradle from which i concluded that below given libraries are causing the crash.

compile ('com.google.apis:google-api-services-translate:v2-rev47-1.22.0') {
exclude group: 'com.google.guava'
}
compile ('com.google.cloud:google-cloud-translate:0.5.0') {
exclude group: 'io.grpc', module: 'grpc-all'
exclude group: 'com.google.protobuf', module: 'protobuf-java'
exclude group: 'com.google.api-client', module: 'google-api-client-appengine'
}

The specified versions are :
Android Studio Version: 3.1.4
compileSdkVersion: 22
buildToolsVersion: 22
minSdkVersion: 16
targetSdkVersion: 22

These are the logs:

I need to know exactly why is this happening. And what is the solution.
Any help is most appreciated. Thanks.
