Answer 1

I had exactly the same problem. I solve this issue with updating every Google support library to the latest version (27.1.0 in time of writing this solution). Also I updated compileSdkVersion to version 27 and buildToolsVersion to version 27.0.3. I hope that this will solve you problem.

Answer 2

just you have to add multidex true and add one dependency to it. check code:

defaultConfig {
    ...
    multiDexEnabled true
}

add dependency:

dependencies {
 compile 'com.android.support:multidex:1.0.1'
}

and if you want to know multidex in details please lokk into below link : https://developer.android.com/studio/build/multidex.html

Happy Coding...
