No specific way to load from fragments to a layout

[psavarmattas]

📝 Description

I have a fragment in which I want to load the pdf in from storage in the pdf layout I put in the fragment layout xml. The view option I see in your library is only to start from a activity and I don't have the option to use that, therefore is there any option that i'm missing? This might not be a bug but I can't seem to figure it out and really want to use your library as it looks so good for my usecase.

Workaround Description:

Okay so I found a workaround to load the files as URI link which can be rendered directly from a fragment. Thanks for an amazing library. Once my project is public I will give you the appropriate credit.

Code:

PDFViewerFragment.kt

class PDFViewerFragment : Fragment() {

    private var _binding: FragmentPdfViewerBinding? = null
    private lateinit var progressIndicator: LinearProgressIndicator
    private val binding get() = _binding!!

    override fun onCreateView(
        inflater: LayoutInflater, container: ViewGroup?,
        savedInstanceState: Bundle?
    ): View {
        _binding = FragmentPdfViewerBinding.inflate(inflater, container, false)
        return binding.root
    }

    override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
        super.onViewCreated(view, savedInstanceState)

        progressIndicator = view.findViewById(R.id.progressIndicator)

        progressIndicator.visibility = View.VISIBLE
        Log.d("PDFViewerFragment", "Showing progress indicator")

        val pdfPath = getFilePath(context, "paperport_001.pdf")
        Log.d("PDFViewerFragment", "Constructed PDF path: $pdfPath")

        try {
            binding.pdfView.initWithUrl(
                url = pdfPath,
                lifecycleCoroutineScope = lifecycleScope,
                lifecycle = lifecycle
            )
            Log.d("PDFViewerFragment", "PDF Viewer launched successfully")
            progressIndicator.visibility = View.GONE
            Log.d("PDFViewerFragment", "Hiding progress indicator")
        } catch (e: Exception) {
            Toast.makeText(requireContext(), "Error opening PDF: $e", Toast.LENGTH_LONG).show()
            Log.e("PDFViewerFragment", "Error opening PDF:", e)
            progressIndicator.visibility = View.VISIBLE
            Log.d("PDFViewerFragment", "Showing progress indicator")
        } finally {
            Log.d("PDFViewerFragment", "Closing PDF Viewer")
        }
    }

    override fun onDestroyView() {
        super.onDestroyView()
        _binding = null
    }

    private fun getFilePath(context: Context?, filename: String): String {
        return if (context != null && context.filesDir != null) {
            val filesDir = context.filesDir.absolutePath
            "file://$filesDir/$filename"
        } else {
            // Handle cases where context or filesDir is missing:
            "file:///$filename"  // Assume default location or provide alternative strategy
        }
    }
}
