If you're using a library like Retrofit to manage your network requests (which I highly recommend), you could easily add the token as header to your request with:

OkHttpClient.Builder httpClient = new OkHttpClient.Builder();  
httpClient.addInterceptor(new Interceptor() {  
    @Override
    public Response intercept(Interceptor.Chain chain) throws IOException {
        Request original = chain.request();

        // Request customization: add request headers
        Request.Builder requestBuilder = original.newBuilder()
            .header("Authentication", "accessToken"); // <-- this is the important line

        Request request = requestBuilder.build();
        return chain.proceed(request);
    }
});

OkHttpClient client = httpClient.build();
