Answer 1

Enable multidex build.

Make below changes in app gradle. Add multiDexEnabled true

android {
    defaultConfig {
       ....
        minSdkVersion 17
        targetSdkVersion 28
        multiDexEnabled true
        versionCode 1
        versionName "1.0"
    }

In dependencies add:

implementation 'com.android.support:multidex:1.0.3'
