Unable to run on Android (error: package okhttp3 does not exist)

I can't run my project on Android because the error : error: package okhttp3 does not exist import okhttp3.MediaType; keeps showing on run.

I've tried several solutions like adding compile 'com.squareup.okhttp3:okhttp:3.4.1' to my build.gradle file but nothing worked !

RN : 0.39.2
RNFB : 0.10.0

We worked around this by adding okhttp3 react-native-fetch-blob's build.gradle file:

dependencies {
    compile 'com.facebook.react:react-native:+'
    compile 'com.squareup.okhttp3:okhttp:3.4.1'
    //{RNFetchBlob_PRE_0.28_DEPDENDENCY}
}
