[jitendra7020]

Hi i'm using your PDF viewer and my goes crash .Please help ASAP. Below is my application crash log.

Hi i implemented a sample eclipse project which reads file using fromFile() you can find the same here https://drive.google.com/file/d/0BwRMp8dK9LMLQmVhZkNMQ19WMUU/view?usp=sharing

My app also crashes all the time at some PDF files (especially the ones created with Word 2010) with following strack trace:

Maybe this works? https://code.google.com/p/vudroid/issues/detail?id=55#c1

It happens when I open a new PDF in the PDFview allready showing a PDF (not when inititally opening the PDF).

Another crash; probably with the same cause:

I seemed to be only happening when you load a second PDF file at my project. It had nothing to do with the type of PDF.

I tried this work-around below and it seems to be working! :smile: Before I load a new PDF, I remove the existing PDFview from its parent and add it again.

I call this function before loading a new PDF:

/**
 * Hack because of a bug in PDFview; It crashes when you load a second PDF
 */
private void reinitPdfView(){
    ViewGroup group = (ViewGroup) mPdfView.getParent();
    group.removeView(mPdfView);
    mPdfView = null;
    mPdfView = new PDFView(this, null);
    mPdfView.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));
    group.addView(mPdfView);
}

[dharmakshetri]

I followed you sample code in your but could display any pdf file, just display out blank:

  public class PDFViewActivity extends Activity implements OnPageChangeListener {

public static final String SAMPLE_FILE = "sample.pdf";

public static final String ABOUT_FILE = "about.pdf";

PDFView pdfView;

String pdfName = SAMPLE_FILE;

Integer pageNumber = 1;

@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    pdfView= (PDFView) findViewById(R.id.pdfView);
}

void afterViews() {
    display(pdfName, false);
}

public void about() {
    if (!displaying(ABOUT_FILE))
        display(ABOUT_FILE, true);
}

private void display(String assetFileName, boolean jumpToFirstPage) {
    if (jumpToFirstPage) pageNumber = 1;
    setTitle(pdfName = assetFileName);

    pdfView.fromAsset(assetFileName)
    .defaultPage(1)
    .showMinimap(false)
    .enableSwipe(true)
    .onPageChange(this)
    .load();
}

@Override
public void onPageChanged(int page, int pageCount) {
    pageNumber = page;
    setTitle(format("%s %s / %s", pdfName, page, pageCount));
}

@Override
public void onBackPressed() {
    if (ABOUT_FILE.equals(pdfName)) {
        display(SAMPLE_FILE, true);
    } else {
        super.onBackPressed();
    }
}

private boolean displaying(String fileName) {
    return fileName.equals(pdfName);
}

}

Guys could you tell me, what is wrong with this code .

Workaround for loading from files:

Copy native libraries to your project. Works for me. Anyway this libvudroid.so is big one :(.

[ashwinbhaskar]

I am getting the same exception when I try to open a file that is stored in Internal Storage. But when I try to open a file from External Storage it works. Why is this happening?

[ashwinbhaskar]

@bholota : What did you mean by "copy native libraries to your project"?

[ghost]

I bet it's totally different issue. My configuration somehow didn't detect .so files inside library (vudroid ones) and I had add those manually. But you can try.

[ashwinbhaskar]

@bholota : I am not sure if including the files manually would solve the issue. Because the problem lies in the PdfPage.open(Native Method) method. This is a native method. I am really not sure what the problem could be.

[ghost]

I'm also thinking that my problem was related with something else. Maybe with older release.

[bakonMa]

Have you solved it

[pzienowicz]

I still have this problem. Loading file from assets works like a charm, but when I try to open the same file by "fromFile" method my app crashes!
