I have done some looking around and have gotten a decent understanding of how to generate a Pdf with the native android tools. I'm still a bit confused on how the xml/view should be structured. Because for me, it never gets loaded. I'll start with the xml. which is shown below

<?xml version="1.0" encoding="utf-8"?>

<FrameLayout android:id="@+id/dh_pdf_viewer_root"

         xmlns:android="http://schemas.android.com/apk/res/android"

         android:layout_width="match_parent"

         android:layout_height="match_parent">



<com.duethealth.lib.pdfviewer.ui.PdfDocumentView

    android:id="@+id/dh_pdf_view"

    android:layout_width="match_parent"

    android:layout_height="match_parent"/>



<TextView

    android:id="@+id/dh_pdf_page_counter"

    android:layout_width="wrap_content"

    android:layout_height="wrap_content"

    android:layout_gravity="bottom|center_horizontal"

    android:layout_margin="@dimen/dh_padding_default"

    android:background="@color/dh_color_background_75"

    android:gravity="center"

    android:padding="@dimen/dh_padding_default"

    android:textAppearance="@style/DuetHealth.TextAppearance.ListLine2"/>



<include layout="@layout/dh_include_loading_50"/>

So the TextView at the bottom is used to display my page counter(if its needed), I dont need to extend ViewPager, its just a place holder.

public class PdfDocumentView extends ViewPager {

public void writePdf(File file) {



    PdfDocument document = new PdfDocument();



    PageInfo pageInfo = new PageInfo.Builder(300, 300, 1).create();



    Page page = document.startPage(pageInfo);



    View content = findViewById(R.id.dh_pdf_view);

    content.measure(800, 480);

    content.layout(0, 0, 800, 480);



    content.draw(page.getCanvas());



    document.finishPage(page);



    try {

        FileOutputStream fileOutputStream = new FileOutputStream(file.getPath());

        document.writeTo(fileOutputStream);

        document.close();

        fileOutputStream.close();

    } catch (IOException e) {

        Timber.e(e, "Error writing PDF");

    }



}

I dont understand what ViewGroup I should be extending for PdfDocumentView or can the whole document just go into an ImageView or something? When I go through the DEBUG, everything seems to be working, the PDF is being successfully pulled from URL into byte stream then written out to a file and then to memory and there are no errors. Seems my problem is somewhere with the View itself.
