Sample app isn't working

I'm having all sorts of issues with the example app.

I'm posting this here as I'm not sure if the issues are related to nativescript-image-picker or nativescript-background-http or both.

I've attached a video that shows the process of selecting an image(s) on Android 6.0.1. The image picker becomes very unresponsive and I see a black screen. When the picker does eventually close there is no image thumbnail for the file being uploaded.

It looks as though the progress console logs are being duplicated and the final eventName is 'error'

...

On iOS there are no folder preview thumbnails. Once you exit a folder, the picker automatically closes after a couple of seconds meaning that you can't navigate to another folder to pick other images. Uploading seems fine.

Hi @3rror404, I tested that case and found that the issue with a black screen on Android has been related to ImageSource saveToFile method and the way it is called in the sample project - just after we getting the image source of the selected image. You could do something like the attached code below and to set setTimeout, which will trigger image save after we navigate back to the app.

setTimeout(function() {
                        let saved = imagesource.saveToFile(path, "png");

                        if(saved){
                            var task = sendImages("Image"+counter+".png", path);
                            var item = new observable.Observable();
                            item.set("thumb", imagesource);
                            item.set("uri", "Test"+counter+".png");
                            item.set("uploadTask", task);

                            imageItems.push(item);
                        }
                    }, 100);

Regarding the returned error, this is seems to be related to the android-upload-service which has been exposed inside the nativescript-background-http plugin, however this error should not prevent from the image upload.

About iOS could you provide some more info about the problem and the way you expect it to work?

I look forward to hearing from you.
