Alaways goin in onFailure in retrofit2.0 - retrofit2

Question

I am trying to hit the api : www.xyz.com/abc_cc/cc/userregister/newuser
This is my Code :
public class MainActivity extends AppCompatActivity {
public static final String BASE_URL = "abc.com/abc_cc/cc/";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(BASE_URL)
.client(getUnsafeOkHttpClient())
.addConverterFactory(GsonConverterFactory.create())
.build();
Endpoints endpoints= retrofit.create(Endpoints.class);
endpoints.newuser("{\"full_name\":\"sss\",\"states_id\":\"20\",\"mobile\":\"9876543210\",\"password\":\"******\",\"accept_terms\":true,\"Userid\":\"0\",\"refer\":\"\",\"ip-address\":\"1.2.3.4\",\"device_type\":\"samsung J5\",\"os-version\":\"5.0.1\",\"client\":\"app\",\"secret_key\":\"44\"}")
.enqueue(new retrofit2.Callback<Items>() {
#Override
public void onResponse(retrofit2.Call<Items> call, retrofit2.Response<Items> response) {
System.out.println("onResponse : "+response.message());
System.out.println("onResponse : "+response.body());
System.out.println("onResponse : "+response.code());
System.out.println("onResponse : "+response.errorBody());
System.out.println("onResponse : "+response.isSuccessful());
System.out.println("onResponse : "+response.raw());
System.out.println("onResponse : "+response);
}
#Override
public void onFailure(retrofit2.Call<Items> call, Throwable t) {
System.out.println("onFailure"+call);
}
});
}
public static OkHttpClient getUnsafeOkHttpClient() {
try {
// Create a trust manager that does not validate certificate chains
final TrustManager[] trustAllCerts = new TrustManager[] { new X509TrustManager() {
#Override
public void checkClientTrusted(
java.security.cert.X509Certificate[] chain,
String authType) throws CertificateException {
}
#Override
public void checkServerTrusted(
java.security.cert.X509Certificate[] chain,
String authType) throws CertificateException {
}
#Override
public java.security.cert.X509Certificate[] getAcceptedIssuers() {
return new java.security.cert.X509Certificate[0];
}
} };
// Install the all-trusting trust manager
final SSLContext sslContext = SSLContext.getInstance("TLS");
sslContext.init(null, trustAllCerts,
new java.security.SecureRandom());
// Create an ssl socket factory with our all-trusting manager
final SSLSocketFactory sslSocketFactory = sslContext
.getSocketFactory();
OkHttpClient okHttpClient = new OkHttpClient();
okHttpClient = okHttpClient.newBuilder()
.sslSocketFactory(sslSocketFactory)
.hostnameVerifier(org.apache.http.conn.ssl.SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER).build();
return okHttpClient;
} catch (Exception e) {
throw new RuntimeException(e);
}
}
}
Interface :
public interface Endpoints {
#POST("/userregister/newuser")
#FormUrlEncoded
Call<Items> newuser(#Field("Data") String Data);
}
POJO class :
public class Items {
#SerializedName("Response-Status")
#Expose
private Boolean responseStatus;
#SerializedName("Response-Validate")
#Expose
private Boolean responseValidate;
#SerializedName("Response-Message")
#Expose
private String responseMessage;
#SerializedName("Response-Data")
#Expose
private ResponseData responseData;
public Boolean getResponseStatus() {
return responseStatus;
}
public void setResponseStatus(Boolean responseStatus) {
this.responseStatus = responseStatus;
}
public Boolean getResponseValidate() {
return responseValidate;
}
public void setResponseValidate(Boolean responseValidate) {
this.responseValidate = responseValidate;
}
public String getResponseMessage() {
return responseMessage;
}
public void setResponseMessage(String responseMessage) {
this.responseMessage = responseMessage;
}
public ResponseData getResponseData() {
return responseData;
}
public void setResponseData(ResponseData responseData) {
this.responseData = responseData;
}
}
I am getting this response :
{protocol=http/1.1, code=404, message=Not Found, url=www.xyz.com/userregister/newuser}
I have given the proper url then why is it taking only half of it?
I have tried the example from https://code.tutsplus.com/tutorials/sending-data-with-retrofit-2-http-client-for-android--cms-27845. This example and the link given in the example are working fine, but if I do the same with my url then I get the above error

Answer 1

I Hope kindly check your parsing issues may occurred.
#Override
public void onFailure(retrofit2.Call<Items> call, Throwable t) {
System.out.println("onFailure"+call);
//add this lije you got exceptions.
t.printStackTrace();
}

Answer 2

Change your Endpoints interface for this:
public interface Endpoints {
#POST("userregister/newuser")
#FormUrlEncoded
Call<Items> newuser(#Field("Data") String Data);
}
Note that I removed the trailing slash /. This way Retrofit appends the path you defined to the BASE_URL.

Answer 3

refer to the docs for Retrofit.Builder for a more detailed explanation, but pay particular attention to these bits:
Base URLs should always end in /.
A trailing / ensures that endpoints values which are relative paths
will correctly append themselves to a base which has path components.
...
Endpoint values which contain a leading / are absolute.
Absolute values retain only the host from baseUrl and ignore any
specified path components.
as presently written, the path referenced in your call to Endpoints.newuser() is absolute, and therefore the path segments after the host in your base URL are dropped (as this is the documented behavior).
therefore, you should change your Endpoints interface to use relative paths instead, like so:
public interface Endpoints {
#POST("userregister/newuser")
#FormUrlEncoded
Call<Items> newuser(#Field("Data") String Data);
}
