Initialize addheaders as global in okhttpClient

As I need to initialize add headers as global to get headers in all API call, I have tried but while debug its not sending the headers in API call.
val client = OkHttpClient.Builder()
.authenticator { _, response ->
response.request().newBuilder().addHeader(
"authorization","123").build()
}
.connectTimeout(60, TimeUnit.SECONDS)
.readTimeout(60, TimeUnit.SECONDS)
.writeTimeout(60, TimeUnit.SECONDS)
.build()
AndroidNetworking.initialize(applicationContext, client)

Can you replace your code with mentioned below and try again
OkHttpClient.Builder().add(new Interceptor() {
#Override
public com.squareup.okhttp.Response intercept(Chain chain) throws IOException {
Request.Builder requestBuilder = chain.request().newBuilder();
requestBuilder.header("Content-Type", "application/json");
return chain.proceed(requestBuilder.build());
}
})
.connectTimeout(60, TimeUnit.SECONDS)
.readTimeout(60, TimeUnit.SECONDS)
.writeTimeout(60, TimeUnit.SECONDS)
.build()
AndroidNetworking.initialize(applicationContext, client)

addInterceptor intercept NullPointException. in Retrofit2

I got this error:
Fatal Exception: kotlin.KotlinNullPointerException
com.example.manager.helper.my_api.MyServiceGenerator$createService$$inlined$-addInterceptor$1.intercept (Interceptor.kt:81)
okhttp3.internal.http.RealInterceptorChain.proceed (RealInterceptorChain.kt:100)
okhttp3.internal.connection.RealCall.getResponseWithInterceptorChain$okhttp (RealCall.kt:197)

java.util.concurrent.ThreadPoolExecutor.runWorker (ThreadPoolExecutor.java:1133)
java.lang.Thread.run (Thread.java:762)
And I have no idea why it caused.
What I implemented is:
val logging = HttpLoggingInterceptor()
if (BuildConfig.DEBUG) { // If Build is Debug Mode, Show Log
logging.level = HttpLoggingInterceptor.Level.BODY // Logs request and response lines and their respective headers and bodies (if present).
} else { // Otherwise, show nothing.
logging.level = HttpLoggingInterceptor.Level.NONE // No logs
}
val client = OkHttpClient.Builder()
client.addInterceptor {
val original = it.request()
val request = original.newBuilder()
.header("User-Agent", MyApp.httpUserAgent!!)
.build()
it.proceed(request)
}
client.addInterceptor(logging)
.connectTimeout(30, TimeUnit.SECONDS)
.callTimeout(30, TimeUnit.SECONDS)
.readTimeout(30, TimeUnit.SECONDS)
.writeTimeout(30, TimeUnit.SECONDS)

You are not finished building of your client. That's why it's null. In general you forgot to call build() method.
That's how it have to be implemented.
val client = OkHttpClient.Builder()
.addInterceptor(logging)
.connectTimeout(30, TimeUnit.SECONDS)
.callTimeout(30, TimeUnit.SECONDS)
.readTimeout(30, TimeUnit.SECONDS)
.writeTimeout(30, TimeUnit.SECONDS)
.build()

If you're using !! in your codes you should use it with a null check. Like this
if(MyApp.httpUserAgent != null) {
val request = original.newBuilder()
.header("User-Agent", MyApp.httpUserAgent!!)
.build()
else {
//here do something in case of null
}

I have the same problem when upgrade logging-interceptor from 3.10.0 to 4.7.2
Debug find cause is ssl factory
// old code
builder.sslSocketFactory(sslSocketFactory)
change the code to new code
// new code
builder.sslSocketFactory(sslSocketFactory, x509TrustManager)

RxAndroid + Retrofit callTimeout doesn't trigger onError

I am using RxAndroid + Retrofit to make http request. Code looks like below:
Interceptor headerInterceptor = getHeaderInterceptor();
HttpLoggingInterceptor httpLoggingInterceptor = new HttpLoggingInterceptor();
httpLoggingInterceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
OkHttpClient client = new OkHttpClient.Builder()
.connectTimeout(60, TimeUnit.SECONDS)
.writeTimeout(60, TimeUnit.SECONDS)
.readTimeout(60, TimeUnit.SECONDS)
.callTimeout(5, TimeUnit.SECONDS)
.addInterceptor(headerInterceptor)
.addInterceptor(httpLoggingInterceptor)
.build();
Gson gson = new GsonBuilder()
.setLenient()
.create();
sRetrofit = new Retrofit.Builder()
.baseUrl(BASE_URL)
.addCallAdapterFactory(RxJava2CallAdapterFactory.create())
.addConverterFactory(GsonConverterFactory.create(gson))
.client(client)
.build();
Use it like this:
ApiProvider.provideApi(MyApi.class)
.submit(id, mRequest)
.subscribeOn(Schedulers.io())
.observeOn(AndroidSchedulers.mainThread())
.subscribe(
response -> {
Log.w("tag", "success");
},
throwable -> {
Log.w("tag", "error");
}
);
I set connectTimeout / readTimeout / writeTimeout to be 60 seconds, and set callTimeout to be 5 seconds.
I know this configuration may be not reasonable but I just want to get a timeout exception after 5 seconds, and the Log.w("tag", "error"); could be called.
However, I found this line will never be called for my testing. And if I set connectionTimeout to 1 second, then this line will be called immediately.
So what I should do if I want callTimeout to trigger the log error line?

As for as I can see, I think your problem maybe isn't from how many seconds you set for callTimeout(5, TimeUnit.SECONDS), I think your maybe Rx stream have already throw some errors, so stream just break you can get any response from here. However, you reset time seconds to 1s, and then you restart app, this time stream not break and you get error.
So simple re-test it again to make sure your stream won't break even before enter this subscribe.
And I have been test with some stupid implementations:
class MainActivity : AppCompatActivity() {
val delayInterceptor = object : Interceptor {
override fun intercept(chain: Interceptor.Chain): okhttp3.Response {
Thread.sleep(6000L)
return chain.proceed(chain.request())
}
}
val client: OkHttpClient = OkHttpClient.Builder()
.connectTimeout(60, TimeUnit.SECONDS)
.writeTimeout(60, TimeUnit.SECONDS)
.readTimeout(60, TimeUnit.SECONDS)
.callTimeout(5, TimeUnit.SECONDS)
.addInterceptor(delayInterceptor)
.build()
val retrofit: Retrofit = Retrofit.Builder()
.baseUrl("https://en.wikipedia.org/")
.addCallAdapterFactory(RxJava2CallAdapterFactory.create())
.addConverterFactory(GsonConverterFactory.create())
.client(client)
.build();
data class Wiki(
#SerializedName("type")
val type: String
)
interface WikiService {
#GET("api/rest_v1/page/random/summary")
fun getRandomSummary(): Single<Wiki>
}
#SuppressLint("CheckResult")
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
retrofit.create(WikiService::class.java)
.getRandomSummary()
.subscribeOn(Schedulers.io())
.observeOn(AndroidSchedulers.mainThread())
.subscribe({
Log.d("tag", "success")
}, {
Log.e("tag", "error")
})
}
}

I finally find the the cause.
I was using com.jakewharton.retrofit2.adapter.rxjava2.RxJava2CallAdapterFactory, which had been deprecated per its readme: https://github.com/JakeWharton/retrofit2-rxjava2-adapter
This is now DEPRECATED!
Retrofit 2.2 and newer have a first-party call adapter for RxJava 2: https://github.com/square/retrofit/tree/master/retrofit-adapters/rxjava2
After switching to retrofit2.adapter.rxjava2.RxJava2CallAdapterFactory, everything start working nicely.
And BTW for any guy who might be interested in what the differences are between them two? Attach the key info I found below:

Retrofit 2: Setting Timeouts With No Effect

i am using the following:
implementation "com.squareup.retrofit2:converter-gson:2.6.0"
fun getOkHTTPClient(time: Int, interceptor: Interceptor): OkHttpClient {
val client = OkHttpClient.Builder()
.addInterceptor(interceptor)
.connectTimeout(5, TimeUnit.SECONDS)
.writeTimeout(5, TimeUnit.SECONDS)
.readTimeout(5, TimeUnit.SECONDS)
.callTimeout(5, TimeUnit.SECONDS)
.retryOnConnectionFailure(false)
return client.build()
}
retrofit2.Retrofit.Builder()
.baseUrl("$url/")
.addConverterFactory(GsonConverterFactory.create())
.client(okHttpClient)
If i change the timeouts to 10 seconds, 20, 50, 500 etc.... the effect is the same. the call timeout is not obeying these rules.
Am i missing something?
Note: i am using Asynchronous requests if it helps in debugging the case

java.net.SocketTimeoutException occurred after 1s~3s but my ok http timeout set 10s

My app is using Retrofit+okhttp.
Sometimes, it throw SocketTimeoutException just through
1s~3s after request but my okhttp timeout is setting 10s.
It's my code.
private static OkHttpClient getClient() {
OkHttpClient client = new OkHttpClient.Builder()
.connectTimeout(10, TimeUnit.SECONDS)
.writeTimeout(10, TimeUnit.SECONDS)
.readTimeout(10, TimeUnit.SECONDS)
.addInterceptor(headerinterceptor)
.build();
return client;
}
public static XXXX XXXX() {
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(XXXX)
.addConverterFactory(StatusProcessConverter.create(new GsonBuilder().setLenient().create()))
.addCallAdapterFactory(RxJava2CallAdapterFactory.create())
.client(getClient())
.build();
XXXX methods = retrofit.create(XXXX.class);
return methods;
}
Can anyone help me ... why the sockettimeout occur less than 10s...
