Okhttp3, FileNotFoundException on retrofit2 POST

Question

As i'm showing a part of the code below, i'm trying to POST an image with retrofit2. Android Studio

I really can't understand what is the error, hope someone cud help me with this problem.

Imge service

import okhttp3.MultipartBody
import okhttp3.RequestBody
import okhttp3.ResponseBody
import retrofit2.Call
import retrofit2.http.Multipart
import retrofit2.http.POST
import retrofit2.http.Part


interface ImageUploadService {

    @Multipart
    @POST("uploadfile")
    fun saveImage(
        @Part("description") description: RequestBody,
        @Part image: MultipartBody.Part
    ): Call<ResponseBody>
}

Imge request and retrofit init

import com.code.delegate.RequestDelegateOnSuccessFull
import com.code.retrofit.RetrofitInitialize
import com.code.retrofit.service.ImageUploadService
import com.softwareplace.workout.delegate.Delegate
import okhttp3.MultipartBody
import okhttp3.RequestBody
import okhttp3.ResponseBody
import retrofit2.Call
import retrofit2.Callback
import retrofit2.Response


class ImageRequest(url: String) {

    private val service: ImageUploadService = RetrofitInitialize(url)
        .retrofit
        .create(ImageUploadService::class.java)

    fun postImageFile(delegate: Delegate<ResponseBody>, image: MultipartBody.Part, description: RequestBody) {
        service.saveImage(image = image, description = description).enqueue(object : Callback<ResponseBody> {
            override fun onFailure(call: Call<ResponseBody>, t: Throwable) {
                delegate.onFailure(t)
            }

            override fun onResponse(call: Call<ResponseBody>, response: Response<ResponseBody>) {
                RequestDelegateOnSuccessFull(response = response, delegate = delegate).run()
            }

        })
    }
}

            GlideImageSet(context = this).glideImageSet(imageView = user_image_profile, data = bitmap)
        }
    }
}

When i try to POST this image file, i got this error

As you can see on the error message, No such file or directory, it looks like it can't find the file from the path.

Answer 1

I did many testes, so i got a solution as i will show in code below, but if you know a better solution, show me.

private fun postImage() {
    user_register_button.setOnClickListener {

        if (selectedImage != null) {
            var imageFile = File(baseContext.cacheDir, "${System.currentTimeMillis()}")
            imageFile.createNewFile()

            var arrayOutputStream = ByteArrayOutputStream()
            getBitmapFromUri(selectedImage).compress(Bitmap.CompressFormat.JPEG, 100, arrayOutputStream)
            var outputStream = FileOutputStream(imageFile)
            outputStream.write(arrayOutputStream.toByteArray())
            outputStream.flush()
            outputStream.close()


            var descriptionBody = RequestBody.create(MediaType.parse("image/*"), imageFile)
            val imagePart = MultipartBody.Part.createFormData("file", "${System.currentTimeMillis()}", descriptionBody)

            ImageRequest(getString(R.string.base_url_file_upload)).postImageFile(
                image = imagePart, delegate = object : Delegate<ResponseBody> {
                    override fun onSuccessFull(isSuccessFull: Boolean, response: ResponseBody?, message: String?) {
                        if (isSuccessFull) {
                            Log.i("ResponseBody", response.toString())
                        } else {
                            Log.i("ResponseError", message)
                        }
                    }

                    override fun onFailure(exception: Throwable) {
                        Log.i("Error", exception.message)
                        exception.printStackTrace()
                    }

                })

        }
    }
}

@Throws(IOException::class)
private fun getBitmapFromUri(uri: Uri): Bitmap {
    val parcelFileDescriptor = contentResolver.openFileDescriptor(uri, "r")
    val fileDescriptor = parcelFileDescriptor.fileDescriptor
    val image = BitmapFactory.decodeFileDescriptor(fileDescriptor)
    parcelFileDescriptor.close()
    return image
}
