When PDF file is about 50 MB it doesn't work

[10zgurr]

Hi,

thank you for the library first of all. I have this issue that when I try with a 50 MB file's URL (https://www.learningcontainer.com/sample-pdf-files-for-testing) it doesn't work :/

[ncubes-dev]

I also have this problem but overally the library is awesome

@10zgurr @ncubes-dev i don't understand, i try to upload the 50mp pdf file to my host and i can open it whitout problem. Can you try to load this url pls? https://myreport.altervista.org/sample-50-MB-pdf-file.pdf Also what url you try to open? And can you give me more info, like the behavior or if the lib throw an exception?

[10zgurr]

this is the url im using -> https://www.learningcontainer.com/sample-pdf-files-for-testing even with your URL it still doesn't work, it stucks with the background color and there is no info or error logs in the logcat

[GRizzi91]

This url (https://www.learningcontainer.com/sample-pdf-files-for-testing) is not a pdf resource so it's normal that you cant open the pdf. All in all can you share your code? If you prefer you can upload your project on a private repo and add me has a contributor @10zgurr

val pdfState = rememberVerticalPdfReaderState(
        resource = ResourceType.Remote("https://myreport.altervista.org/sample-50-MB-pdf-file.pdf"),
        isZoomEnable = true
    )
    Box {
        VerticalPDFReader(
            state = pdfState,
            modifier = Modifier
                .fillMaxSize()
                .background(color = Color.Gray)
        )
        pdfState.file?.let { file ->
            Button(
                modifier = Modifier.size(60.dp),
                onClick = {
                    // save file
                    share(context = context, pdfFile = file)
                }
            ) {
                Icon(
                    modifier = Modifier.size(60.dp),
                    painter = painterResource(id = android.R.drawable.ic_menu_share),
                    contentDescription = "share"
                )
            }
        }
    }

Hello @GRizzi91, your lib looks awesome and works fine with PDF files for 2-5 pages, but with bigger files, I have a problem:

On some devices, I have an OutOfMemoryError. (Sony Xperia Z5 Compact)

On a virtual device, Google Pixel 2 (with default memory settings), when I try to load a huge PDF file, it looks like nothing happened, and the loading is stuck.

[GRizzi91]

@ihor-bezeka this sounds me strange, in demo app the remote file is a pdf with more thant 5 page and work well. I also tested with bigger and heavy pdf and i never get OOM. Can you let me have the pdf that you are talking abount?

[ihor-bezeka]

@GRizzi91, sorry for the late response. Here it is: https://www.thebookcollector.co.uk/sites/default/files/the-book-collector-example-2018-04.pdf

I guess the problem is with the page count and not just the size of the file.

[GRizzi91]

@ihor-bezeka can you try to run a build from this branch pls? Test branch i have uploaded the pdf on my space and replaced the url in the test app so you can try to open the pdf by selecting the "Remote resource" section i cannot reproduce the problem.

[ihor-bezeka]

@GRizzi91 The same problem with the assets pdf file (raw/lorem_ipsum.pdf). On Pixel 2 API v.23

I have tested on Samsung s10, s22, and emulators Resizable (Experimental) API v.33 everything works fine. But on Pixel 2 API v.23, OOM throws at the start of loading, and on Pixel 2 API v.29, OOM throws near the end of the loading even if the memory settings of these emulators are the same.

Maybe setting these memory settings will help with catching the OOM:

[GRizzi91]

Ok i found the problem, ill fix the issue as soon as possible

[GRizzi91]

@ihor-bezeka @10zgurr New version is out 1.1.2, now the lib will require only 1/8 of the memory required by the 1.1.1

[ihor-bezeka]

@GRizzi91, it works much better! But now I have OOM when trying to scroll through a PDF document. When the document scrolled to the 3-5 page, I got OOM.

Should I open a new Issue, or can this bug be solved in the scope of this issue?

[ncubes-dev]

When I open local documents that have many pages or bigger size
