Version: 8.0.0

Release Date: September 30, 2020

This release of PDFTron for Xamarin brings the core PDF functionality and iOS and Android Tools functionality inline with version 8.0.0 of the iOS and Android SDKs. More information can be found on What's New for iOS and What's New for Android .

• Intuitive UI design and advanced customization APIs with new beta viewer PdfViewCtrlTabHostFragment2 . Check out the integration guide , customization guide and the migration guide

• Theme overhaul, CustomAppTheme is no longer required to be hard coded as-is in your application. All UI components are now mapped to specific attributes that you can define in your application. Then the theme will be passed into the viewer with ViewerBuilder.usingTheme. It is also possible to continue what you are currently doing, see breaking change section for how to upgrade

• Adds border effect to Square annotation, available styles are default line and cloud shape

• Adds support for the xls format
• Adds support for Right-to-left languages within office files
• See all cross-platform changelog here: 8.0.0

• Theme has been reworked so you will no longer need to have a theme called CustomAppTheme in your application. ViewerBuilder now accepts a custom theme with usingTheme API. However, if you are currently overriding CustomAppTheme in your application, to upgrade to this version you will need to change the parent theme of your CustomAppTheme or custom theme to use CustomAppThemeBase. Otherwise you will need to define all the custom attributes described in the theme guide .

Typically, all you need to do is changing the parent theme of CustomAppTheme in your application to CustomAppThemeBase:

<style name="CustomAppTheme" parent="CustomAppThemeBase">
    <item name="colorPrimary">@color/app_color_primary_day</item>
    <item name="colorPrimaryDark">@color/app_color_primary_dark_day</item>
    <item name="colorAccent">@color/app_color_accent</item>
</style>

If you are experiencing issues with upgrading, please don't hesitate to contact us .

The new UI includes an all-new annotation toolbar system. The new UI:

• has better UX and a more attractive UI
• is more easily customizable by APIs
• accommodates more tools
• is user-customizable
• is nearly 100% backward compatible with the existing UI, making migration easy.

The new UI is in beta, and you can learn more about it in our guide . For information on migrating to use the new UI in your project, please see our migration guide .
