Uploading to S3 signed URL's with a file as an origin works without problems, but trying to do it with an Uri I get from my ActivityResult is not working for me.
Here is what I try:
I'm using a InputStreamRequestBody class like described here: https://commonsware.com/blog/2020/07/05/multipart-upload-okttp-uri.html
class InputStreamRequestBody(
private val contentType: MediaType,
private val contentResolver: ContentResolver,
private val uri: Uri
) : RequestBody() {
override fun contentType() = contentType
override fun contentLength(): Long = -1
@Throws(IOException::class)
override fun writeTo(sink: BufferedSink) {
val input = contentResolver.openInputStream(uri)
input?.use { sink.writeAll(it.source()) }
?: throw IOException("Could not open $uri")
}
}
My Retrofit UploadAPI interface:
interface UploadAPI {
@PUT
suspend fun uploadFile(
@Header("x-amz-acl") contentType: String,
@Url uploadUrl: String,
@Body file: RequestBody
): Response<Unit>
companion object {
const val BASE_URL = "https://....com"
}
}
And here my Retrofit Singleton in AppModule:
@Provides
@Singleton
fun provideUploadApi(): UploadAPI {
return Retrofit.Builder()
.baseUrl(UploadAPI.BASE_URL)
.addConverterFactory(GsonConverterFactory.create())
.build()
.create(UploadAPI::class.java)
}
And then calling the InputStreamRequestBody class with my Uri (in my repository) and calling the retrofit instance and upload function:
val resolver = context.contentResolver
val type = ("image/jpeg").toMediaType()
val contentPart = InputStreamRequestBody(type, resolver, content)
uploadAPI.uploadFile(
"public-read",
mySignedUrl,
contentPart
)
this is what my logginInterceptor tells me:

I have the strong feeling that I cannot just pass the instance of InputStreamRequestBody as a requestBody eventhough this class inherrits from RequestBody.
