RxJava: Unable to create call adapter for rx.Observable error

问题:

What i do:

public interface ApiInterface {     @Multipart         @POST("/android/upload/index.php")         Observable<Response> postImage(@Part MultipartBody.Part image,   @Part("name") RequestBody name); } 

Model:

public interface Model {  Observable<Response> postImage(MultipartBody.Part image, RequestBody name); } 

Impl:

public class ModelImpl implements Model {     ApiModule apiModule = ApiModule.getInstance();  @Override     public Observable<Response> postImage(MultipartBody.Part image, RequestBody name) {         return apiModule.getApi().postImage(image,name);     } } 

Presenter:

RxPhoto.requestUri(context, TypeRequest.GALLERY)         .flatMap(new Func1<Uri, Observable<Response>>() {             @Override             public Observable<Response> call(Uri uri) {                  File file = new File(uri.getPath());                 RequestBody reqFile = RequestBody.create(MediaType.parse("image/*"), file);                 MultipartBody.Part body = MultipartBody.Part.createFormData("upload", file.getName(), reqFile);                 RequestBody name = RequestBody.create(MediaType.parse("text/plain"), "upload_test");                 return model.postImage(body, name);               }         }).subscribeOn(Schedulers.io())                 .observeOn(AndroidSchedulers.mainThread())                 .subscribe(new Subscriber<Response>() {                      @Override                     public void onError(Throwable e) {                          Log.d(tag, "error:" + e);                      }                  }); 

I have error:

error:java.lang.IllegalArgumentException: Unable to create call adapter for rx.Observable for method ApiInterface.postImage

UPD:

I change interface and others to :

Observable<uploadAnswer>       public class uploadAnswer {          @SerializedName("success")         @Expose         private String success;          public String getSuccess() {             return this.success;         }      } 

after that my first error gone, now i have this error:

java.io.FileNotFoundException: /document/image:52214: open failed: ENOENT (No such file or directory)

What to do?

UPD2:

I use this function to get file uri:

public String getRealPathFromURIPath(Uri contentURI) {         Cursor cursor = context.getApplicationContext().getContentResolver().query(contentURI, null, null, null, null);         if (cursor == null) {             return contentURI.getPath();         } else {             cursor.moveToFirst();             int idx = cursor.getColumnIndex(MediaStore.Images.ImageColumns.DATA);             return cursor.getString(idx);         }     } 

After that i have this error (is it mean, that i'm right ?? ):

error:android.os.NetworkOnMainThreadException

UPD3:

My short code:

RxPhoto.requestUri(context,TypeRequest.GALLERY)                 .observeOn(AndroidSchedulers.mainThread())                 .doOnNext(new Action1<Uri>(){                      @Override                     public void call(Uri uri) {                          Log.d(tag, "up => " + uri);                          File file = new File(uri.getPath());                         RequestBody reqFile = RequestBody.create(MediaType.parse("image/*"), file);                         MultipartBody.Part body = MultipartBody.Part.createFormData("upload", file.getName(), reqFile);                         RequestBody name = RequestBody.create(MediaType.parse("text/plain"), "upload_test");                          //model.postImage(body, name);                          GetDataSubscription = model.postImage(body,name)                                 .subscribeOn(Schedulers.io())                                 .observeOn(AndroidSchedulers.mainThread())                                 .subscribe();                      }                  })                 .subscribe(); 

I still have errors:

if i change my interface to:

@Multipart     @POST("/upload/index.php")     Observable<String> postImage(@Part MultipartBody.Part image, @Part("name") RequestBody name); 

I have this trace:

*E/AndroidRuntime: FATAL EXCEPTION: main Process: info.masterskaya.om.near, PID: 8618 java.lang.IllegalStateException: Exception thrown on Scheduler.Worker thread. Add onError

UPD4:

I have some results.

Interface:

@Multipart @POST("/upload/index.php") Observable<Void> postImage(@Part MultipartBody.Part image, @Part("name") RequestBody name); 

Main function:

RxPhoto.requestUri(context,TypeRequest.GALLERY)                 .observeOn(AndroidSchedulers.mainThread())                 .doOnNext(new Action1<Uri>(){                      @Override                     public void call(Uri uri) {                          Log.d(tag, "up => " + uri);                         Log.d(tag, "getPath => " + getPath(context,uri));                          String URL = getPath(context,uri);                          File file = new File( URL+"" );                          RequestBody reqFile = RequestBody.create(MediaType.parse("image/*"), file);                         MultipartBody.Part body = MultipartBody.Part.createFormData("upload", file.getName(), reqFile);                         RequestBody name = RequestBody.create(MediaType.parse("text/plain"), "upload_test");                          GetDataSubscription = model.postImage(body,name)                                 .subscribeOn(Schedulers.io())                                 .observeOn(AndroidSchedulers.mainThread())                                 .subscribe();                      }                  })                 .subscribe();

i find HERE

Now i have server error:

UPD5:

I done this f*cking upload!

php test code:

<?php      error_reporting(E_ALL);     ini_set('display_errors', 1);      define('ROOT_DIR', dirname(__FILE__));      $file_path = ROOT_DIR . "";      $file_path = $file_path . basename( $_FILES['upload']['name']);     if(move_uploaded_file($_FILES['upload']['tmp_name'], $file_path) ){         echo '{"result": "success"}';     } else{         echo '{"result": "fail"}';     }  ?> 

All my problems was with right uri on device. Try API 16,19 and 24 all successfull

回答1:

The problem is in the following part:

Observable<Response> 

Response always needs a specified body type. It looks like your response don't have a body, so you should replace it with this:

Observable<Result<Void>> 

...and request the response using result.response()



回答2:

If the name parameter is only String, I think the api should be called like:

public interface ApiInterface {     @Multipart         @POST("/android/upload/index.php")         Observable<Response> postImage(@Part MultipartBody.Part image,   @Part("name") String name); } 


回答3:

Include call adapter factory, if you forget it.

RxJava2: compile 'com.jakewharton.retrofit:retrofit2-rxjava2-adapter:1.0.0'

RxJava : compile 'com.squareup.retrofit:adapter-rxjava:2.0.0-beta2'

Edit:

Ok, is because you need to convert multipart, not text, so change will be here:

RequestBody name = RequestBody.create(MediaType.parse("multipart/form-data"), "upload_test"); 

Also mediatype should be the same

RequestBody reqFile = RequestBody.create(MediaType.parse("multipart/form-data"), file);` 

For more Informations take a look here.
