Not working with okhttp 3.12.8 and hence not working with android lower than 21

[abhishekgargx]

To support lower android version < 21, we required to use okhttp version 3.12.X

when we using this version of okhttp as mentioned above with yourvwo version : 2.8.0

code snippet

 implementation("com.squareup.okhttp3:okhttp:3.12.8") {
        force = true
    }

   implementation 'com.vwo:mobile:2.8.0@aar'
    implementation ('io.socket:socket.io-client:1.0.0') {
        // excluding org.json which is provided by Android
        exclude group: 'org.json', module: 'json'
    }
    // Skip this if you are already including support library in your app.
    implementation 'com.android.support:support-core-utils:28.0.0'

we are getting this error

Now if you use latest version of okhttp which 4.x.x for eg. 4.9.0. there is no error.

But as your readme file , you library support Android 4.0 (API 14) or later

Hey @abhishekgargx , We'll get this checked and will let you know once we have any updates. Thanks for reporting this.

hey @softvar so i found solution to fix this while looking into your code, so basically if we want to use

okhttp version 3.12.X

while your library com.vwo:mobile:2.8.0@aar

we need to set socket.io version to io.socket:socket.io-client:2.0.1 instead of version 1.0.0

Hope this finding help someone else, and they will be not force to moved to min sdk 21 , as we are about to.
