# Customizing page navigation in our Android PDF viewer

After loading a PDF document, you can programmatically interact with it, which allows you to scroll to different pages or zoom in and out. All of the interaction APIs are available on the [`PdfFragment`](https://www.nutrient.io/api/android/nutrient/com.pspdfkit.ui/-pdf-fragment/index.html), which is the core PDF viewer. Furthermore, most methods are also available on the [`PdfActivity`](https://www.nutrient.io/api/android/nutrient/com.pspdfkit.ui/-pdf-activity/index.html).

## Changing the current page

While the user can manually change the current page by doing a swipe gesture on the device, you can also programmatically change pages using [`setPageIndex(int)`](https://www.nutrient.io/api/android/nutrient/com.pspdfkit.ui/-pdf-fragment/set-page-index.html) and [`setPageIndex(int, boolean)`](https://www.nutrient.io/api/android/nutrient/com.pspdfkit.ui/-pdf-fragment/set-page-index.html). You can fetch the current page using [`getPageIndex()`](https://www.nutrient.io/api/android/nutrient/com.pspdfkit.ui/-pdf-fragment/get-page-index.html):

### KOTLIN

```kotlin

val startPage = fragment.getPageIndex()

// Change to page 13 (zero-based page numbers).
fragment.pageIndex = 12

// Go to the last page using a transitioning animation.
val lastPage = document.pageCount - 1
fragment.setPageIndex(lastPage, true)

// Go back to the page where you started off.
fragment.setPageIndex(startPage)

```

### JAVA

```java

final int startPage = fragment.getPageIndex();

// Change to page 13 (zero-based page numbers).
fragment.setPageIndex(12);

// Go to the last page using a transitioning animation.
int lastPage = document.getPageCount() - 1;
fragment.setPageIndex(lastPage, true);

// Go back to the page where you started off.
fragment.setPageIndex(startPage);

```

While [`setPageIndex(int, boolean)`](https://www.nutrient.io/api/android/nutrient/com.pspdfkit.ui/-pdf-fragment/set-page-index.html) gives you complete control of choosing whether or not a page transitioning animation should be performed, [`setPageIndex(int)`](https://www.nutrient.io/api/android/nutrient/com.pspdfkit.ui/-pdf-fragment/set-page-index.html) will intelligently decide whether or not an animation is suitable for the current situation.

### Restore the last viewed page

By default, [`PdfFragment`](https://www.nutrient.io/api/android/nutrient/com.pspdfkit.ui/-pdf-fragment/index.html) will remember the last viewed page of a document and will restore it when loading the document at a later point. This usually provides a better experience when using a document across several sessions. If you would like to disable this mechanism, you can set [`PdfConfiguration#restoreLastViewedPage`](https://www.nutrient.io/api/android/nutrient/com.pspdfkit.configuration/-pdf-configuration/-builder/restore-last-viewed-page.html) to `false`:

### KOTLIN

```kotlin

val config = PdfConfiguration.Builder().restoreLastViewedPage(false).build()

```

### JAVA

```java

final PdfConfiguration config = new PdfConfiguration.Builder().restoreLastViewedPage(false).build();

```
