[BUG] BrowserFetcher not working on Android about skrape.it

[rbri]

yes please give me a sign, will update the readme and make a release if it works for you

[christian-draeger]

Sure. Could you provide the url you want to scrape from?
Then I will try to build a little demo :)

EDIT: found url in Screenshot. Will try tomorrow or at least on Monday

[christian-draeger]

This is a problem of html-unit library running on Android (which skrape{it} is internally using to implement the BrowserFetcher)

[p4ulor]

@christian-draeger this dude was able to solve it. You said that skrape it used html-unit, maybe if you use the new snap shot he mentioned maybe it fixes it HtmlUnit/htmlunit#444 (comment)

[christian-draeger]

I will try tomorrow. If all tests will succeed we can ask @rbri to make it an actual release since for now it's just a snapshot version release. What means the implementation of this version could change at any time. Therefore we should wait for an official html unit release including the fix. I already asked what's the status of the snapshot / if we can expect an official release soon here :)

But as said, I will try to verify if the snapshot version in general will fix our problems here :)

Looking forward to be able to use the BrowserFetcher on Android soon 🎉

HtmlUnit/htmlunit#444 (comment)

OK but that are great news because it means the fetching and rendering of the site in general is working.

Now it's probably just about finding the correct css selectors.
I can try to support at latest on Monday

i am waiting for HtmlUnit/htmlunit-android#1 to make an official release including the fix to make BrowserFetcher work on android

[christian-draeger]

ok i just checked.
since the values you want to extract rely on javascript you will need to use BrowserFetcher.
since the dropdown will need a click to change numbers to per 100g it will not be possible to do this using skrape{it} for now since it is only html parser. but i have plans to make this possible in the near future.

beside from that i could imagine a solution like this, which will give you a map with the category name as key and a list of entries as value:

data class Entry(
    val name: String,
    val amount: String,
    val unit: String,
    val percentDv: String,
)

fun getNuts() = skrape(BrowserFetcher) {
    request {
        url = "https://nutritiondata.self.com/facts/nut-and-seed-products/3086/2"
        timeout = 20_000
    }
    response {
        htmlDocument {
            "#NutritionInformationSlide .m-t13" {
                findAll {

                            }
                        } to it.div {

Wow! Thank you so much! I will analise your code and try it it out. I'm still pretty new to programming and new to website scrapping and this personal project is very important to me, and you helped me a lot! Have a nice week 💯 👍

HtmlUnit/htmlunit#444 (comment)

[p4ulor]

Ok, so I added implementation("it.skrape:skrapeit:0-SNAPSHOT")
The { isChanging = true } wasn't working the build said it didnt recognize
It build succesfully
On compiling, I have error "2 files found with path 'mozilla/public-suffix-list.txt'."
So I added

packagingOptions {
        exclude 'mozilla/public-suffix-list.txt'
    }

But now I have error NutritionTracker\app\build\intermediates\merged_java_res\debug\base.jar: The process cannot access the file because it is being used by another process.

Then I invalidated caches and restart and then it worked.
Then I had the network on main exception, so I added the suspend keyword and such, and then I got this error:

but I think it was because the website was slow, so it magically disappeared when I increased the timeout to 40s or it was a coincidence idk, but even before the 40s, now I'm having the error bellow. #NutritionInformationSlide .m-t13 is that indicator of that key tag for the 8 nutritional tables
I did a push to my repositor so you can check it out

I've been running the code in several ways and testing diferent stuff, the error bellow is now gone appearently, and the present error is the one above

I also tried just using "clearer m-t13" for the Css selector search thing instead of "#NutritionInformationSlide .m-t13" and also didnt work
