What's wrong with my Retrofit configuration? I'm having this error when I'm adding Basic Authentication with my OkHttpClient but when I used the default client without Interceptor it's working. Or is there something wrong with my Gradle Dependencies..?
E/AndroidRuntime﹕ FATAL EXCEPTION: main
java.lang.IllegalArgumentException

Here is my API Service to be called
@GET("Triu-services-portlet.regaccrdetails/get-all-reg-accr-details-by-num-branch-code/num/{num}/branch-code/{branch-code}")
public Observable<List<RegAccrDetails>> getRegAccrDetails(@Path("num") String num, @Path("branch-code")String branchCode);
My OkHttpClient Interceptor
private static OkHttpClient createOkHttpClient() {
String username = "test@liferay.com";
String password = "TEST";
String credentials = username + ":" + password;
final String basic =
"Basic " + Base64.encodeToString(credentials.getBytes(), Base64.DEFAULT);//no_wrap
OkHttpClient client = new OkHttpClient();
client.interceptors().add(new Interceptor() {
@Override
public Response intercept(Chain chain) throws IOException {
Response response = chain.proceed(chain.request());
Request original = chain.request();
// Customize the request
Request request = original.newBuilder()
.header("Authorization", basic)
.header("Accept", "application/json")
//.header("Authorization", "auth-token")//add token for service A4oslsSXZxfbLdk
.method(original.method(), original.body())
.build();
response = chain.proceed(request);
// Customize or return the response
return response;
}
});
return client;
}
Here is my Call for my API
private void liferayAccess(){
Log.d("liferayAccess", "Entered");
APIService service = ServiceGenerator.createService(APIService.class);
Observable<List<RegAccrDetails>> liferayResponse = service.getRegAccrDetails("004589209", "001");
liferayResponse.subscribeOn(Schedulers.newThread()).map(listResponse -> "response index 0 " + listResponse.get(0).getRegNum())
.subscribe( response-> Log.d("Liferay Num", response),
error -> Log.d("Error", error.toString())
);

You're using 2.0.0-beta2 versions of Retrofit plugins which depend on 2.0.0-beta2 version of Retrofit core which still lives in retrofit package and at com.squareup.retrofit coordinates.
compile 'com.squareup.retrofit:adapter-rxjava:2.0.0-beta2'
compile 'com.squareup.retrofit:converter-gson:2.0.0-beta2'
Then you're importing 2.0.0-beta3 version of Retrofit core which lives in retrofit2 package and at com.squareup.retrofit2 coordinates. Basically, it can be used alongside 2.0.0-beta2 or even 1.x version.
compile 'com.squareup.retrofit2:retrofit:2.0.0-beta3'
You're not really using 2.0.0-beta3 at all, because it's incompatible with 2.0.0-beta2 plugins and you'd get compile time errors. Check your imports to verify.
What happened is (most likely) you use everything from retrofit package except for the @GET class which is from retrofit2 package. Despite their identical name these classes are not the same.
Read more about why this happened.
Update the dependency and fix your imports.
compile 'com.squareup.retrofit2:retrofit:2.0.0'
compile 'com.squareup.retrofit2:adapter-rxjava:2.0.0'
compile 'com.squareup.retrofit2:converter-gson:2.0.0'
