Pdf Viewer library for Android

Hello, I am getting a url of the location where the PDF is stored. I want to open the pdf with the pdfviewer. Can I get the guideline to open it as currently I am saving the url in string and then I am passing the string as the path of the pdf to the Activity through the intent

final Intent readPdf = new Intent(getApplicationContext(), PdfViewerActivity.class);
readPdf.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
readPdf.putExtra(PdfViewerActivity.EXTRA_PDFFILENAME, path);
startActivity(readPdf);

It shows me PDF does not exists but the pdf is available. please guide.

Hi, i was trying to use your library to show a pdf in my app ant it gives me that error...

E/APV.PDFRenderer﹕ null java.lang.NullPointerException at android.graphics.Canvas.drawBitmap(Canvas.java:1195) at com.sun.pdfview.PDFRenderer.drawImage(PDFRenderer.java:390) at com.sun.pdfview.PDFImageCmd.execute(PDFPage.java:654) at com.sun.pdfview.PDFRenderer.iterate(PDFRenderer.java:685) at com.sun.pdfview.BaseWatchable.run(BaseWatchable.java:101) at com.sun.pdfview.BaseWatchable.execute(BaseWatchable.java:263) at com.sun.pdfview.BaseWatchable.go(BaseWatchable.java:197) at com.sun.pdfview.PDFPage.getImage(PDFPage.java:237) at segesa.catalogo.VisorPDF$2.doInBackground(VisorPDF.java:117) at segesa.catalogo.VisorPDF$2.doInBackground(VisorPDF.java:73) at android.os.AsyncTask$2.call(AsyncTask.java:287) at java.util.concurrent.FutureTask.run(FutureTask.java:234) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1080) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:573) at java.lang.Thread.run(Thread.java:856)

Its gives me the correct number of pages, but it dosent show anything.

The pdf im trying to open is in that url http://www.cealsa.com/folletoiphone/folletoiphone.pdf But im trying to open it locally, from my internal storage.

Thanks

i add a pdf file with pdfpassword in that class it gives Stackoverflow issues to me.

at line 56

@Override
public void init(int mode, SecretKeySpec keySpec, IvParameterSpec Iv) {
    init(mode, keySpec, Iv); //why recursion?
}

How i can decrease image size without changing image's width and height. (I use curl page project on github). and also sun's pdf reader reads pdf so slow it affects page curl. So i use thread's to handling this problem. But there is a problem here, i must have 10 image to apply this algorithm. But Java's vm breaks project (out of memory error). I found only way change width and height, but page's can not readable (so small). Any idea for that problems?. Thanks for everything, and also sorry for bad English.

If i use the getPage method i get the incorrect page. For example if there is a 10 page pdf file. getPage(0, true) - returns page 1 getPage(1, true) - returns page 1 getPage(2, true) - returns page 2 getPage(3, true) - returns page 3 ... getPage(9, true) - returns page 9 getPage(10, true) - java.lang.ArrayIndexOutOfBoundsException: length=10; index=10

How do i get page 10?

Hello Joe,

I have implemented this library, and It was working as expected Thanks!!, however it does not work well with the latest Android 7 OS (Nougat); the PDF file keeps loading, I have tried a direct path (file:///android_asset/) to the PDFs files, but it did not work. please advise.

Thank you

I have updated a method to get bitmap of pdf page which i want to use. but i am unable to get new jar .Please somebody could help me with this issue. how I am using it..txt

I'm using the PDFViewer library and I have the next System.err:

The code is:

@Nullable
    private static Bitmap renderToBitmap(InputStream inputStream) {
        Bitmap bitmap = null;
        try {
            byte[] decode = org.apache.commons.io.IOUtils.toByteArray(inputStream);
            ByteBuffer byteBuffer = ByteBuffer.wrap(decode);
            PDFPage mPdfPage = new PDFFile(byteBuffer, null).getPage(0);
            float width = mPdfPage.getWidth();
            float height = mPdfPage.getHeight();
            RectF clip = null;
            bitmap = mPdfPage.getImage((int) (width), (int) (height), clip, true, true);
        } catch (IOException ex) {
            ex.printStackTrace();
        }
        return bitmap;
    }

and has been found here.

The exact line that the Androir Monitor says the problem is, is the next: PDFPage mPdfPage = new PDFFile(byteBuffer, null).getPage(0);

Any suggestion? Thank you very much.
