My App was working fine, then i add com.splunk:mint-android-sdk, which required upper version of gradle, so i upgrade the gradle to from 2.1 to 3.3. after that i am facing i
I updated following line of
code: classpath 'com.android.tools.build:gradle:2.3.3'
classpath 'com.google.gms:google-services:3.0.0'
and distributionUrl in gradle-wrapper.properties 'distributionUrl=https\://services.gradle.org/distributions/gradle-3.3-all.zip'
and MOST IMPORTANT is FILE>SETTING>Build,Execution,Deployment>Build Tools>Gradles: Project-level settings: checked :Use default gradle wrapper(recommended)
