In Android, if you open tiff using the code below, you can view only one page even if it contains multiple tiffs. How can I show multiple pages like PDF?

        val config = ViewerConfig.Builder().openUrlCachePath(this.getCacheDir().getAbsolutePath())
            .multiTabEnabled(true)
            .build()
        val fileLink = Uri.parse("file:///android_asset/tiff.tiff")
        DocumentActivity.openDocument(this, fileLink, config)

Hi Sean,

Thank you for contacting us about your question.
We don’t support opening tiff files with multiple pages at the moment.

If you don’t mind, could you please let us know what is your use case and why are you interested in this feature?

I have to show you the contract.
Contracts are multiple pages in tiff format.

Then is it possible to adopt a method that can show multi-page tiff format files by converting to pdf?

Multi-page conversion is not supported in the viewer version yet, however you can convert to PDF then pass to the viewer, for example:

        File tiffFile = Utils.copyResourceToLocal(this, R.raw.tiff_sample, "tiff_sample", ".tiff");
        PDFDoc pdfDoc = new PDFDoc();
        Convert.toPdf(pdfDoc, tiffFile.getAbsolutePath());
        File pdfFile = new File(getCacheDir(),"tiff_sample.pdf");
        pdfDoc.save(pdfFile.getAbsolutePath(), SDFDoc.SaveMode.NO_FLAGS, null);
        pdfDoc.close();

Then use pdfFile to pass in to the ViewerBuilder2, i.e. withUri(Uri.fromFile(pdfFile)).

Could you please give it a try? Thanks.
