Answer 2

I have fixed by enabling the multiDex in the /android/app/build.gradle file.

android {
  defaultConfig {
    .......
    multiDexEnabled true
  }
  ......
}

Answer 3

Got same error a couple of days back, seems you've got to enable multidex to true and delete the build folder.

Go to android/app/build.gradle and add the line multiDexEnabled true and set minSdkVersion to 21 inside defaultConfig like this

...
android{
  ...
  defaultConfig {
    ...
    minSdkVersion 21
    multiDexEnabled true
  }
  ...
}
...

I solve issue by enabling

        // ...
        multiDexEnabled true
    }
    // ...
}

path : android/app/build.gradle

Add the below line to your android/build.gradle file

    ext {
            googlePlayServicesVersion = "16.0.1"
            // ... rest of ext properties
        }
