cordova-plugin-foxitpdf npm version

This plugin adds the ability to easily preview any PDF file in your Cordova application

Installation

cordova plugin add cordova-plugin-foxitpdf

It is also possible to install via repo url directly ( unstable )

cordova plugin add https://github.com/foxitsoftware/cordova-plugin-foxitpdf.git

Large files in the plugin may cause your update to fail. If that is the case, please try again following the steps below:

  1. Clone this project
  2. Add plugin from local using this command :
cordova plugin add ~/xxx/cordova-plugin-foxitpdf (This address is replaced by your own)

Integration for iOS

The iOS version of the cordova plugin only needs a few simple steps to deploy

  1. Unzip Foxit PDF SDK for iOS and copy libs folder into the component’s ios folder. (/xxx/platforms/ios/)

Please use foxitpdfsdk_(version_no)_ios.zip from https://developers.foxitsoftware.com/pdf-sdk/ios/

  1. Target -> General -> Embedded Binaries Add dynamic framework "FoxitRDK.framework" and "uiextensionsDynamic.framework" to Xcode’s Embedded Binaries

  2. Target -> General -> Linked Frameworks and Libraries -> + -> WebKit.framework

Note Do not forget to add pdf files You can add the PDF to Copy Bundle Resources directly. Just left-click the project, find 'Copy Bundle Resources' in the 'Build Phases' tab, click on the + button, and choose the file to add. You can refer to any PDF file, just add it to the Xcode’s Copy Bundle Resources. Or,you can use the pdf file under Document directory in sandbox

Now that the preparatory work has been completed,you can use this plugin everywhere in your project.

Integration for Android

  1. Download foxitpdfsdk_(version_no)_android.zip from https://developers.foxitsoftware.com/pdf-sdk/android/ (Please use Foxit PDF SDK for Android 7.1.0)

  2. Unzip foxitpdfsdk_(version_no)_android.zip and copy libs folder into the component’s android folder. /xxx/platforms/android/

How to use this plugin for cordova developer

  1. Initialize
var sn = 'foxit_sn';
var key = 'foxit_key';
window.FoxitPdf.initialize(sn,key);
  1. Open Pdf File
var path = 'Your file path';
var password = 'password'; // If the PDF document is not encrypted by password, just pass an empty string.

window.FoxitPdf.openDocument(path, password);

How to change the UI of PDF viewer control?

For Foxit PDF SDK for iOS. The UI is handled within the "FoxitRDK.framework" and "uiextensionsDynamic.framework." The files that comes with the evaluation package, however, they also comes with the source, which you can compile and replace accordingly. The UI source can be located at "libs\uiextensions_src" You can find the uiextensions.xcodeproj in the same directory. Just open this project with xcode, modified it to your needs, build, and replace them accordingly in step 2 of the instruction at https://github.com/foxitsoftware/cordova-plugin-foxitpdf#integration-for-ios.

For Android, the UI is located at the binary at libs\FoxitRDKUIExtensions.aar. You can find the source for this binary in the package at foxitpdfsdk_XXX_android.zip at libs\uiextensions_src. You can open this project with Android Studio, modified it, and replaced the FoxitRDKUIExtensions.aar file accordingly. Step 2 of https://github.com/foxitsoftware/cordova-plugin-foxitpdf#integration-for-android is where the instructions on the github page indicates that it is being used.

JS API Reference

window.FoxitPdf.initialize

window.FoxitPdf.initialize(sn,key);

  • options: Initialization options.

  • foxit_sn: the foxit_sn string

  • foxit_key: the foxit_key string

foxit_sn and foxit_key are required, otherwise the initialization will fail. rdk_key and rdk_sn can be found in the libs folder of foxitpdfsdk_(version_no)_ios.zip.

iOS Quirks

  1. The first argument in the preview method currently only supports absolute paths for incoming files.

You can obtain the absolute path to the file using the method provided by the [cordova-plugin-file] (https://github.com/apache/cordova-plugin-file) plugin.

Use the following command to add the [cordova-plugin-file] (https://github.com/apache/cordova-plugin-file) plugin to your project

cordova plugin add cordova-plugin-file
  1. Note: in some cases the resource folders are not added correctly and the number of items is the same because of XCode bug.(e.g. Xcode 8.3.3) In that case, remove the added reference from the project tree and add the Resource using the project tree - Add files to "YourProjectName". Remember to enable the option of "copy items if needed" and "create groups" when using this method.

If an error similar to the one in the following picture appears, try the method in step 2

Quick Example

A PDF file needs to be placed in the project beforehand. The location is in the project root by default

var filePathSaveTo = cordova.file.documentsDirectory + 'getting_started_ios_2.pdf'
window.FoxitPdf.setSavePath(filePathSaveTo);

var filePath cordova.file.applicationDirectory + 'getting_started_ios.pdf';
window.FoxitPdf.openDocument(filePath,'');

window.FoxitPdf.addEventListener('onDocOpened',function(data){
console.log('onDocOpened callback ',data);
console.log('onDocOpened callback info',data.info);
if (data.error == 0){
var data_type = 0x0002;
window.FoxitPdf.importFromFDF(cordova.file.documentsDirectory + 'Annot_all.fdf',data_type, [[0, 1]]);
}
});

Attention

  1. The product is still in its early stage of development. We will continue to focus on refining and improving this project.

  2. If your cordova version is 7.0.0, you might encounter this problem: no such file or directory, open 'xxxx/platforms/android/AndroidManifest.xml' this is a cordova bug, and the solution is provided in the link below: https://cordova.apache.org/announcements/2017/12/04/cordova-android-7.0.0.html

However this a major breaking change for people creating standalone Cordova Android projects. This also means that the locations of files have changed and have been brought in line to the structure used by Android Studio. This may affect plugin.xml files and config.xml files that use edit-config, and make it so plugins that use edit-config will not be able to be compatible with both Android 6.x and Android 7.x. To fix this issue, please do the following in your XML files
