Initializing it with some customization , as it uses OkHttp as networking layer, you can pass custom OkHttpClient while initializing it.
// Adding an Network Interceptor for Debugging purpose :
OkHttpClient okHttpClient = new OkHttpClient() .newBuilder()
.addNetworkInterceptor(new StethoInterceptor())
.build();
AndroidNetworking.initialize(getApplicationContext(),okHttpClient);
Other example : setting custom timeout
OkHttpClient okHttpClient = new OkHttpClient().newBuilder()
.connectTimeout(120, TimeUnit.SECONDS)
.readTimeout(120, TimeUnit.SECONDS)
. writeTimeout(120, TimeUnit.SECONDS)
.build();
AndroidNetworking.initialize(getApplicationContext(),okHttpClient);
