Top Android PDF Viewer Libraries.

PDF Viewer libraries for Android allow developers to integrate PDF viewing capabilities into their applications. These libraries provide various features like zooming, scrolling, text search, annotations, and more. They make it easy to render PDF files and provide a seamless reading experience for users.

1. AndroidPdfViewer​

AndroidPdfViewer is a popular library that enables the rendering of PDF documents in Android applications. It uses the PdfRenderer API available in Android SDK 21 and above, making it efficient and reliable.

Installation​

To add AndroidPdfViewer to your project, you need to include the following dependency in your app-level build.gradle file:

implementation 'com.github.barteksc:android-pdf-viewer:2.8.2'

Usage Example​

To display a PDF file using AndroidPdfViewer, you first need to add a PDFView widget to your layout XML file:

<com.github.barteksc.pdfviewer.PDFView
    android:id="@+id/pdfView"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

Then, in your activity or fragment, you can load a PDF file using the following code:

val pdfView: PDFView = findViewById(R.id.pdfView)
pdfView.fromAsset("sample.pdf")
    .load()

Here, fromAsset("sample.pdf") loads the PDF file from the assets folder. You can also load PDFs from other sources like a file path, URL, or byte array.

For more advanced usage, AndroidPdfViewer provides additional options like password-protected PDF support, custom rendering, and text selection.
