okhttp3 ExceptionInInitializerError 異常處理

okhttp3 在Android4.4上出現下面異常

    java.lang.ExceptionInInitializerError
        at okhttp3.OkHttpClient.newSslSocketFactory(OkHttpClient.java:263)
        at okhttp3.OkHttpClient.<init>(OkHttpClient.java:229)
        at okhttp3.OkHttpClient$Builder.build(OkHttpClient.java:1015)

解決方案

Okhttp創建一個分支用OkHttp3.12.x來支持Android4.x設備，所以把版本號改為3.12.x即可

implementation 'com.squareup.okhttp3:okhttp:3.12.x'
