Question

After adding the facebook dependency in gradle I\'m getting this runtime error:

     compile \'com.facebook.android:facebook-android-sdk:4.6.0\'

Answer 1

You are getting

       java.lang.NoClassDefFoundError: com.squareup.okhttp.internal.Util
        at com.squareup.okhttp.OkHttpClient.(OkHttpClient.java:57)
        at com.venkat.project.http.MyHTTPThread.run(MyHTTPThread.java:127)

NoClassDefFoundError for OkHttpClient

public class NoClassDefFoundError extends LinkageError

Thrown if the Java Virtual Machine or a ClassLoader instance tries to load in the definition of a class (as part of a normal method call or as part of creating a new instance using the new expression) and no definition of the class could be found.

Quote from NoClassDefFoundError

You should use

compile 'com.facebook.android:facebook-android-sdk:4.10.0'

After that you can get this error finished with non-zero exit value 2

Then

defaultConfig {
    ...
    minSdkVersion 14 //lower than 14 doesn't support multidex
    targetSdkVersion //Yours

    // Enabling multidex support.
    multiDexEnabled true
}

dependencies {
 implementation 'com.android.support:multidex:1.0.0'
}

1. Add multiDexEnabled true

2. Call implementation'com.android.support:multidex:1.0.2'

OkHttp perseveres when the network is troublesome: it will silently recover from common connection problems. If your service has multiple IP addresses OkHttp will attempt alternate addresses if the first connect fails. This is necessary for IPv4+IPv6 and for services hosted in redundant data centers.

You can call latest version

implementation'com.squareup.okhttp3:okhttp:3.2.0'

Then

Clean and Re-Build & Sync Your Project . Hope this helps .
