Enhanced annotation toolbar, multi-tab navigation, stamp and signature flows, and more. Upgrade now for a better Starting with Version 7.1.5, Apryse's Android SDK ships with a brand new viewer [`PdfViewCtrlTabHostFragment2`](https://sdk.apryse.com/api/android/javadoc/reference/com/pdftron/pdf/controls/PdfViewCtrlTabHostFragment2.html) which includes an updated user interface containing: improvements to the annotation toolbar, a better multi-tab navigation experience, improvements to stamp and signature flows, and more. `PdfViewCtrlTabHostFragment2` is a drop-in replacement for `PdfViewCtrlTabHostFragment` and steps for migrating from the old viewer can be found in migration guides. `PdfViewCtrlTabHostFragment` will continue to use the existing UI, however this will be deprecated in future versions of Apryse. You can check out the `new-ui` branch in the [Android Samples GitHub repository](https://github.com/ApryseSDK/pdftron-android-samples/tree/new-ui/) to see this new UI in action. ## Annotation Toolbar The annotation toolbar has been completely revamped in order to accommodate our ever expanding set of tools. The Pan tool bas been removed from the toolbar and the toolbar itself is now scrollable. By default when no tools are selected in the toolbar, the pan tool is selected. ![](https://226546913-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F0QItsdFBmuuL9ezHimHy%2Fuploads%2Fgit-blob-c5790d629455a6a7c992a2b42e4492c47f0acd23%2F9c4ee5625625f1966fba3f0beff3082a68a7d16e-600x1067.gif?alt=media) ## Annotation Toolbar Switcher In order to help users find the right tool for the job, we've grouped the tools into specific toolbars. For example some new toolbars are: Annotation Toolbar, Draw Toolbar, Fill and Sign Toolbar, Prepare Form Toolbar, Insert Toolbar, Measure Toolbar, and Pens Toolbar. ![](https://226546913-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F0QItsdFBmuuL9ezHimHy%2Fuploads%2Fgit-blob-e6e77a4bc733fc69e57b89cd5c6105a094be94b4%2Fbfad304bbd895b3138231893ea80d174a0f4c7f5-436x779.png?alt=media) ## Multi-tab Switcher Dialog The tab layout for switching between multiple documents in the viewer has been removed on Phones.
