Android PDFRenderer compiling issue

Question

I am creating an application using PDFRenderer at API 5.0 I had to add pdfrenderer.jar externally also now it show's the following error - "The constructor PDFRenderer(ParcelFileDescriptor) is undefined" Can anyone help... This is new to me..

Answer 1

Use PDFRenderer(ParcelFileDescriptor input) where input is a seekable file descriptor.

Pdf Renderer basically takes a file descriptor as its parameter and you havent supplied any.

Refer the developer page https://developer.android.com/reference/android/graphics/pdf/PdfRenderer.html

private void render() {
    try {
        Log.e("In render()","render");
        imageView = (ImageView) findViewById(R.id.imageView);
        int REQ_WIDTH = 1;
        int REQ_HEIGHT = 1;
        REQ_WIDTH = imageView.getWidth();
        REQ_HEIGHT = imageView.getHeight();
        Log.e("In render2()","render2");
        System.out.println("req_height"+REQ_HEIGHT+" "+"REQ_WIDTH"+REQ_WIDTH);

       Bitmap bitmap = Bitmap.createBitmap(REQ_WIDTH, REQ_HEIGHT, Bitmap.Config.ARGB_4444);


        File file = new File("/home/woigames/Desktop/PDF/DebitCards-tc.pdf");

        PDFRenderer renderer = new PDFRenderer(ParcelFileDescriptor.open(file, ParcelFileDescriptor.MODE_READ_ONLY));

        if(renderer != null)
        {
            Log.i("renderer not null","check");
        }
        else 
        {
            Log.i("renderer is null","check");
        }
        final int pageCount = renderer.getPageCount();

        if (currentPage < 0) {
            currentPage = 0;
        } else if (currentPage > renderer.getPageCount()) {
            currentPage = renderer.getPageCount() - 1;
        }

        Matrix m = imageView.getImageMatrix();
        Rect rect = new Rect(0, 0, REQ_WIDTH, REQ_HEIGHT);
        renderer.openPage(currentPage).render(bitmap, rect, m, PdfRenderer.Page.RENDER_MODE_FOR_DISPLAY);

        imageView.setImageMatrix(m);
        imageView.setImageBitmap(bitmap);
        imageView.invalidate();
        renderer.close();

    } catch (Exception e) {
        e.printStackTrace();
    }

Add api level 21 in you manifest and try .Lolipop pdf renderer requires a min sdk level of 21

<uses-sdk android:minSdkVersion="21" />
