Realtime collaboration setup

This tutorial only applies to Xamarin.Android.

linkPrerequisites

  • Minimum API: 21
  • Java 8

Visual Studio 2019 is required

<PropertyGroup>
  <AndroidEnableDesugar>true</AndroidEnableDesugar>
  <AndroidDexTool>d8</AndroidDexTool>
</PropertyGroup>

linkStep 1: Integration

  1. Integrate PDFTron core and the tools library as described here.
  2. Open the NuGet package manager by right click on your project, and click Manage NuGet Packages.... Then in Browse tab, search for PDFTron.

Insall:

NuGet for Collab

linkStep 2: Add the viewer

  1. Update your AndroidManifest.xml as described in Step 1 of this guide.
  2. Create the CollabViewerTabHostFragment, and start it like any other Android Fragment.

    private void addViewerFragment(AppCompatActivity activity, Android.Net.Uri fileUri)
    {
        // Create a custom ViewerConfig used to initialize the viewer fragment
        var viewerConfig = new ViewerConfig.Builder()
            .MultiTabEnabled(false)
            .OpenUrlCachePath(this.CacheDir.AbsolutePath)
            .Build();
        // Create the Fragment using CollabViewerBuilder
        var tabHostFragment = (CollabViewerTabHostFragment)CollabViewerBuilder
            .WithUri(fileUri)
            .UsingConfig(viewerConfig)
            .Build(this);
        // Add the Fragment to your activity
        var ft = activity.SupportFragmentManager.BeginTransaction();
        ft.Replace(Resource.Id.fragment_container, tabHostFragment, null);
        ft.Commit();
    }

where R.id.fragment_container is the resource id of a layout in your activity that will contain your fragment:

For example:

<?xml version="1.0" encoding="utf-8"?>
<!-- This FrameLayout will contain our viewer fragment -->
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/fragment_container"
    android:layout_width="match_parent"
    android:layout_height="match_parent"/>
