AndroidPdfLibrary

A port of Apache's PdfBox 2.0.8 library to be usable on Android. Most features should be implemented by now. You can manipulate and render the pdf. At present rendering only supports bitmap rendering from android pdfrenderer API.

Features

1. Compatible with All Android OS from lollipop
2. Compatible with Android Go as well
3. Split and save the pdf
4. Dynamic pdf rendering from server
5. Working with password protected pdf

Usage

Import the library to your project

Before calls to library are made, it is highly recommended to initialize the library. Add the following line before calling library methods

PDFResourceLoader.init(getApplicationContext());

Save the pdf

            PDFHandler handler = new PDFHandler(Looper.getMainLooper());
            try
            {
                handler.prepareForDroidNative("originalpdfPath", "password of the pdf")
                        .setProgressListener(new OnManipulateProgressListener()
                        {
                            @Override
                            public void onProgress( int i )
                            {
                                Log.d("progress", "pdf progress" + i);
                            }

                            @Override
                            public void onProcessComplete( int i, int numberOfFiles, int numberOfPages )
                            {
                                switch (i)
                                {
                                    case OnManipulateProgressListener.STATUS_COMPLETE:
                                Log.d("download", "number of files generated" + numberOfFiles);
                                    break;
                                }
                            }
                        }).splitAndSave("filepath to store the pdf", "number of pages to split at", "password to encrypt with");
            } catch (IOException e)
            {
                e.printStackTrace();
            }

To open pdf

Intialize the PDFPageExtractor

                    PDFInfo[] pdfInfos = new PDFInfo["number of files generated"];
                for (int i = 0; i < pdfInfos.length; i++) {
                    pdfInfos[i] = new PDFInfo("file path"+ (i + 1) + ".pdf", "password used for encrypting");
                }
                final PDFPageExtractor _extractor = new PDFPageExtractor(number of pages to split while splitting, pdfInfos);
                

Use the extractor instance to render the page

// TO intiate programatically
            PDFPageView pageView = new PDFPageView(container.getContext(),isLandscape);
//  Can also inflate from layout
            PDFPageView pageView = findviewbyid("your id");           

            pageView.setPageWidth(1116);
            pageView.setPageHeight(1546);

// using the below lines will render and set the page image to the pdfpageview
            pageView.setPageIndex(position);
            _extractor.loadPage(pageView);

Progressive Rendering

Progressive rendering

Provide base url in download base link and url to append in the download link. The library will append page number sequentially on its own.

Pre-Requisite

The pdf should not have more than one page.

Example

basedownload url = "http://www.pdfexample.com/"
appendurl = "mypath/pdfname"
final url by library = basedownload url +appendurl +"1.pdf"

            Intent intent = new Intent(this,ProgressiveExtractor.class);
            intent.setAction(IntentActions.ACTION_RENDER);
            intent.putExtra(IntentKeys.ITEM_ID,_issueId);
            intent.putExtra(IntentKeys.DOWNLOAD_LINK,appendDownloadUrl);
            intent.putExtra(IntentKeys.DOWNLOAD_BASE_LINK,baseDownloadUrl);
            intent.putExtra(IntentKeys.TOTAL_PAGE,_totalPages);
            bindservice......
            ...
            ..
            
                ServiceConnection mServiceConnection = new ServiceConnection()
    {
        @Override
        public void onServiceConnected( ComponentName name, IBinder service )
        {
            mExtractor = ((ProgressiveExtractor.ExtractorBinder) service).getProgressiveExtractor();
        }

        @Override
        public void onServiceDisconnected( ComponentName name )
        {
            MagsLogHelper.debugLog("extractorser","service is unbound");
            mExtractor = null;
        }
    };
    
    ....
    ....
    ....
    

           pageView.setPageIndex("pagenumber");
            mExtractor.renderPage(_issueId,pdfpageview);
