I am using localization in my android app

while language is set to Arabic, in the file uploading process of okhttp (okhttp:3.12.0) I am getting this error

and my block of code is

final MediaType MEDIA_TYPE_PNG = MediaType.parse("image/*");
            formBody = new MultipartBody.Builder()
                    .setType(MultipartBody.FORM)
                    .addFormDataPart("action", "updateprofile")
                    .addFormDataPart("userfile", file.getName(), RequestBody.create(MEDIA_TYPE_PNG, file))
                    .addFormDataPart("userid", user.getId())
                    .addFormDataPart("name", name.getText().toString())
                    .build();

how can I resolve this issue

Answer 1

try encoding the file name like this :

URLEncoder.encode(file.getName(), "utf-8")

So that your code becomes

final MediaType MEDIA_TYPE_PNG = MediaType.parse("image/*");
        formBody = new MultipartBody.Builder()
                .setType(MultipartBody.FORM)
                .addFormDataPart("action", "updateprofile")
                .addFormDataPart("userfile", URLEncoder.encode(file.getName(), "utf-8"), RequestBody.create(MEDIA_TYPE_PNG, file))
                .addFormDataPart("userid", user.getId())
                .addFormDataPart("name", name.getText().toString())
                .build();
