Kotlin retrofit Multipart problem with send file on server(server work on laravel)

i have a problem with sending files over using retrofit to my API server. When i send data over using the #Body anotation but without a file the data gets added. When i use #multipart i keep getting response.code()==401, with me using postman sending data with files through my API it works perfectly fine. The issue lies within the kotlin app and retrofit.
i used every possible way. I used multipart without file, same problem. i tried sending just the file and it was the same thing. I don't have a clue where the problem is or what it could be. using body allows me to send data over while with #multipart it looks like as if they just didn't want to transfer over. any recommendations on what to do would be very much appreciated.
myCode:
interface FarmSpaceApi {
#POST("auth/register")
fun RegisterUserApi(#Body user: User):Call<User>
#POST("auth/login")
fun LoginUserApi(#Body user: Userlogin):Call<LoginData>
//#POST("fields/create")
#Headers("Content-Type: application/json;charset=UTF-8")
#POST("fields/show")
fun getFields(#Body userId: UserId,#Header("Authorization")token:String):Call<Field2>
#Multipart
#Headers("Content-Type: application/json;charset=UTF-8")
#POST("fields/create")
fun addfield(#Header("Authorization") token:String,
#Part image:MultipartBody.Part,
#Part("fieldstype") fieldstype: RequestBody,
#Part("field_size_in_ha") field_size_in_ha: RequestBody,
#Part("harvest_in_this_year") harvest_in_this_year: RequestBody,
#Part("user_id") user_id: RequestBody):Call<FieldNewResponse>

Send image and form data at the same time using Retrofit in android kotlin

can you help me guys what's wrong with my code? So I need to send an image and form data into the database with retrofit. it drives me into OnResponse, but there is no change in my database. I tried using multipart and requestbody but it still doesn't work
btn_Verifikasi.setOnClickListener {
val file = File(tv.text.toString())
val requestFile = file.asRequestBody("multipart/form-data".toMediaType())
val body = MultipartBody.Part.createFormData("foto_reseller", file.name, requestFile);
val sharedPreferences = getSharedPreferences("sharedPrefs", android.content.Context.MODE_PRIVATE)
val savednohp = sharedPreferences.getString("nohp",null)
val savedpin = sharedPreferences.getString("pin",null)
val savednama = sharedPreferences.getString("namaReseller",null)
val alamatReseller = sharedPreferences.getString("alamatReseller",null)
val nohpreseller = savednohp!!.toRequestBody("text/plain".toMediaType())
val pinreseller = savedpin!!.toRequestBody("text/plain".toMediaType())
val emailreseller = "".toRequestBody("text/plain".toMediaType())
val namareseller = savednama!!.toRequestBody("text/plain".toMediaType())
val alamatreseller = alamatReseller!!.toRequestBody("text/plain".toMediaType())
val isverified = "".toRequestBody("text/plain".toMediaType())
val apiService = ApiService.getInstance().create(ApiEndpoint::class.java)
apiService.registerReseller(nohpreseller,namareseller,emailreseller,body,alamatreseller, pinreseller,isverified)
.enqueue(object : Callback<ResellerResponse>{
override fun onResponse(
call: Call<ResellerResponse>, response: Response<ResellerResponse>) {
Toast.makeText(this#RegisterFotoResellerActivity, "bisa", Toast.LENGTH_SHORT).show()
Log.d("TAG","bisa yuhhh")
}
override fun onFailure(call: Call<ResellerResponse>, t: Throwable) {
Log.d("TAG","durung bisa kyeeehhh")
}
})
}
#Multipart
#POST("../api/reseller/creates.php")
fun registerReseller(
#Part("no_hp") no_hpreseller:RequestBody,
#Part("nama") nama_reseller:RequestBody,

Android upload files to s3 bucket - Bad Request

I am trying to upload files to s3 bucket but I am getting 400 Bad Request or file not found.
I have tried various solutions but still no luck.
Solution 1:
I followed this instructions
class InputStreamRequestBody(
private val contentResolver: ContentResolver,
private val uri: Uri
): RequestBody() {
override fun contentType(): MediaType? =
contentResolver.getType(uri)?.toMediaTypeOrNull()
override fun writeTo(sink: BufferedSink) {
contentResolver.openInputStream(uri)?.source()?.use(sink::writeAll)
}
override fun contentLength(): Long =
contentResolver.query(uri, null, null, null, null)?.use { cursor ->
val sizeColumnIndex: Int = cursor.getColumnIndex(OpenableColumns.SIZE)
cursor.moveToFirst()
cursor.getLong(sizeColumnIndex)
} ?: super.contentLength()
}
Used it like
#Multipart
#PUT
fun uploadFile(#Url url: String, #Part file: MultipartBody.Part): Single<Response<Any>>
val file = File(uri.path)
val requestBody = InputStreamRequestBody(contentResolver!!, uri)
val filePart = MultipartBody.Part.createFormData("file", file.name, requestBody)
packageApi.uploadFile(url, filePart)
This results in Bad Request
Solution 2:
Same as previous but this time without Multipart
#PUT
fun uploadFile(#Url url: String, #Body file: RequestBody): Single<Response<Any>>
val requestBody = InputStreamRequestBody(contentResolver!!, uri)
packageApi.uploadFile(url, requestBody)
This also results in Bad Request
Solution 3:
Now I abandoned InputStreamRequestBody class and used the traditional way mentioned here
#Multipart
#PUT
fun uploadFile(#Url url: String, #Part file: MultipartBody.Part): Single<Response<Any>>
val file = File(uri.path)
val requestFile = file.asRequestBody("multipart/form-data".toMediaTypeOrNull())
val body = MultipartBody.Part.createFormData("file", file.name, requestFile)
packageApi.uploadFile(url, body)
This results in java.io.FileNotFoundException: /document/image:95: open failed: ENOENT (No such file or directory)
Any suggestion/solution is appreciated!

i did this in my project like
val key: String = AWS_DIRECTORY + fileFullName
var transferUtility: TransferUtility? = null
private var s3Client: AmazonS3? = null
val region = Region.getRegion(Regions.AP_SOUTH_1)
s3Client = AmazonS3Client(awsCredentials, region)
transferUtility=TransferUtility.builder().s3Client(s3Client).context(activityContext)
.defaultBucket(AWS_BUCKET)
.build()
val uploadObserver = transferUtility?.upload(
AWS_BUCKET,
key,
file,
CannedAccessControlList.PublicRead
)
uploadObserver?.setTransferListener(object : TransferListener {
override fun onStateChanged(id: Int, state: TransferState) {
if (TransferState.COMPLETED == state) {
} else if (TransferState.FAILED == state) {
}
}
override fun onProgressChanged(id: Int, bytesCurrent: Long, bytesTotal: Long) {
}
override fun onError(id: Int, ex: Exception) {
}
})

How can I solve this error :Expected BEGIN_ARRAY but was BEGIN_OBJECT at line 1 column 2 path $

Your json return as JSON object. But you are trying to convert into Json array
Call<List<Loginresponse>> - you try to convert result as JSON Array (list)
Solution
Get the raw json result & convert the pojo using http://www.jsonschema2pojo.org/ and try again

You are trying to store json object in list that's why you are getting error .
check your JSON response start with { curly bracket it means it is object not an array . array start with [ square bracket .
#PUT("/user/profile/{userId}")
fun updateProfile(#Header("Authorization") token: String?, #Path("userId") userID: String, #Part file: MultipartBody.Part): Call<List<Loginresponse>>
replace Call<List<Loginresponse>> with Call<Loginresponse> all over where you using updateProfile method

Uploading images to server using retrofit

I' trying to upload an image to server using retrofit2. I think that the way I send data is not correct but I haven't figure out yet where is my problem.
I should send the data in this format: {"file": image, "userID": userId}
This is my code in retrofit interace: #POST("avatar")
fun uploadImage(#Body data: Data ) : Call<ResponseBody>
I have created an object Data with file and userID I don't know if this is the right way. I have seen also this example
ublic interface UploadAPIs {
#Multipart
#POST("/upload")
Call<ResponseBody> uploadImage(#Part MultipartBody.Part file, #Part("name") RequestBody requestBody);
}
But I really don't understand well, how can I sen an object with part multipart
This is how I create image file that I get from gallery in my fragment
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
super.onActivityResult(requestCode, resultCode, data)
if (resultCode == Activity.RESULT_OK)
when(requestCode){
GALLERY -> {
val selectedImage= data!!.data
val file = File(selectedImage.path)
val data = Data(file, userID)
val call = api!!.uploadImage(data)
call.enqueue(object: Callback<ResponseBody>{
override fun onFailure(call: Call<ResponseBody>, t: Throwable) {
Toast.makeText(context, t.message, Toast.LENGTH_SHORT).show()
}
override fun onResponse(call: Call<ResponseBody>, response: Response<ResponseBody>) {
val response = response.body()!!.string()
println("Response " + response)
//response says user does not exist because the way I send data is not correct
}
})
}
CAMERA -> {
//code here
}
}
}
This is the class that I create for Data object
class Data (val file: File, userID: Int)
I would be grateful if anyone can help me :)
Updated code:
#Multipart
#POST("avatar")
fun uploadImage(
#Part("userID") user_ID: RequestBody,
#Part image: MultipartBody.Part) : Call<ResponseBody>
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
super.onActivityResult(requestCode, resultCode, data)
if (resultCode == Activity.RESULT_OK)
when(requestCode){
GALLERY -> {
val selectedImage= data!!.data
val bitmap = MediaStore.Images.Media.getBitmap(context!!.contentResolver, selectedImage)
avatar.setImageBitmap(bitmap)
val file = File(getRealPathFromURI(selectedImage))
val id = RequestBody.create(MediaType.parse("text/plain"), userID.toString())
//val reqBody = RequestBody.create(MediaType.parse(activity!!.contentResolver.getType(selectedImage)!!), file)
val reqBody = RequestBody.create(MediaType.parse("image/*"), file)
val body = MultipartBody.Part.createFormData("file", file.name, reqBody)
val call = api!!.uploadImage(id, body)
call.enqueue(object: Callback<ResponseBody>{
override fun onFailure(call: Call<ResponseBody>, t: Throwable) {
Toast.makeText(context, t.message, Toast.LENGTH_SHORT).show()
println("Failure")
}
override fun onResponse(call: Call<ResponseBody>, response: Response<ResponseBody>) {
if (response.isSuccessful){
println("Successful " + response.body()?.string())
}else{
response.errorBody()?.string()
println("Error " + response.headers().toString())
}
}
})
}
CAMERA -> {
//code
}
}
}

override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
super.onActivityResult(requestCode, resultCode, data)
if (resultCode == Activity.RESULT_OK)
when(requestCode){
GALLERY -> {
val selectedImage= data!!.data
val bitmap = MediaStore.Images.Media.getBitmap(context!!.contentResolver, selectedImage)
avatar.setImageBitmap(bitmap)
val file = File(getRealPathFromURI(selectedImage))
val id = RequestBody.create(MediaType.parse("text/plain"), userID.toString())
val reqBody = RequestBody.create(MediaType.parse("image/jpeg"), file)
val body = MultipartBody.Part.createFormData("file", file.name, reqBody)
val api = RetrofitClient.getInstance().apiService
val call = api!!.uploadImage(id, body)
call.enqueue(object: Callback<ResponseBody>{
override fun onFailure(call: Call<ResponseBody>, t: Throwable) {
Toast.makeText(context, t.message, Toast.LENGTH_SHORT).show()
println("Failure")
}
override fun onResponse(call: Call<ResponseBody>, response: Response<ResponseBody>) {
if (response.isSuccessful){
println("Successful " + response.body()?.string())
}else{
response.errorBody()?.string()
println("Error " + response.headers().toString())
}
}
})
}
CAMERA -> {
//code here
}
}
}
And in API interface:
#Multipart
#POST("avatar")
fun uploadImage(
#Part("userID") user_ID: RequestBody,
/*#Part("file") name: RequestBody*/
#Part image: MultipartBody.Part) : Call<ResponseBody>
