Android Studio 3.0 Execution failed for task: unable to merge dex

Question

android studio was getting build error while build execution with following:

Error:Execution failed for task \':app:transformDexArchiveWithExternalLi

Answer 1

1)Please add multiDexEnabled true
2)if you get compilation error then check your app level build.gradle weather same dependencies are implemented with different versions.
3)Remove one if you find same dependencies.

android { compileSdkVersion 28 defaultConfig {

    minSdkVersion 17
    targetSdkVersion 28
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    multiDexEnabled true
}

hope it works fine :) Happy Coding
