![]() It is still under active development although most of its features should be implemented by now. Implementation ‘:android-pdf-viewer:3.2.0-beta.1’ PdfBox-AndroidĪbout: PdfBox-Android is a port of Apache’s original PdfBox library that can be used on Android. To navigate to your app’s adle file, make sure that your project view is set to Android and go to Gradle Scripts->adle(Module:YourProjectName.app) and add the given dependency: You can add this library by simpling navigating to your adle file in Android Studio and adding the following dependency. ![]() An APK must contain all these libraries to run on every device available on the market, causing a tad bit hike in the file size. This is because AndroidPdfViewer depends on PdfiumAndroid, which is a set of native libraries (almost 16 MB) for many architectures. However, the only downside of AndroidPdfViewer is that your resultant APK files can be a bit large in size. Therefore, you have two versions to choose from that best suit your needs. The difference between the two versions is that Version 1.x uses a different engine for drawing documents on canvas. AndroidPdfViewer 1.x is separately available on the AndroidPdfViewerV1 repo, where it can be developed independently. One goes with the version names AndroidPdfViewer 1.x and the other goes with AndroidPdfViewer 2.x. There are two versions of AndroidPdfViewer.

Now that we know what PDF and external libraries are, let’s look at three of Android’s most-used PDF libraries. When you’re building an app that exists in multiple APK variations, such as a free and paid version and you need the same core components in both, you can simply add the same libraries for both.When you are using a service whose code has already been written, you can simply add its library as opposed to writing the entire code by yourself.When you’re building multiple apps that use some of the same components, such as activities, services, or UI layouts, you can simply copy-paste the same libraries in your multiple apps.The following are some of the advantages of doing so: Using external libraries in an Android Studio project makes things easier. So when you do not need any android specific resources in a library you should create a java library.īenefits of using external libraries in your Android Studio project But it does not allow you to include Android resources or manifest files, which is very useful for code reuse in Android projects. A JAR file is useful for many projects especially when you want to share code with other platforms. Java Library: Java library builds a Java ARchive file (JAR file).It allows you to add Android-specific components like resources and manifest files, which allows you to bundle in shared resources like layouts and drawables in addition to Java classes and methods. Android Library Module: Android Library Module compiles into an Android Archive (AAR) file that you can use as a dependency for an Android app module.We can use two types of libraries in our Android Studio project: But, instead of compiling into an APK that runs on a device, an Android library compiles into an Android Archive (AAR) file that you can use as a dependency for an Android app module. It can include everything needed to build an app, including source code, resource files, and an Android manifest. What is an external library file in Android Studio?Īn Android library is structurally the same as an Android app module. They are mostly used as standard printable documents. Developed by Acrobat, PDF files are used for saving textual and visual(images) content and hyperlinks. If you’ve ever downloaded a printable form or document from the Web, there’s a good chance it was a PDF file. They are one of the most commonly used file types today. PDF files stand for Portable Document Format files. So let’s get started without further ado. First, we will be covering some basic definitions and then move on to the PDF libraries. This blog will be looking at three of the most used PDF libraries for Android along with a detailed how-to. If you want to develop your PDF reader or were looking to integrate a PDF library into your Android Studio project, look no more! Your search for “Most popular PDF libraries for Android” has landed you in the perfect place.
