asimmon / mupdf-for-xamarin-android

A port of the MuPDF Android library for Xamarin Android. With this library, you will be able to read, write, modify PDF files as well as convert pages to images.

I write blog posts about .NET, Azure, other Microsoft technologies and software development in general on https://anthonysimmon.com.

mupdf-for-xamarin-android's Issues

Using MuPDFPageView shows a blank page

I get a blank page when using the library with the following code:

MuPDFCore core = new MuPDFCore(this, path);
Bitmap mSharedHqBm = Bitmap.CreateBitmap(parent.Width, parent.Height, Bitmap.Config.Argb8888);

var pageView = new MuPDFPageView(this, null, core, new Point(parent.Width, parent.Height), mSharedHqBm);
pageView.SetPage(0, new PointF(parent.Width, parent.Height));
parent.AddView(pageView);

Add arm64 version of libmupdf_java.so to libs folder

Can't use the library on my Pixel C:

dalvik.system.PathClassLoader[DexPathList[[zip file "/data/app/com.mypackge-1/base.apk"],nativeLibraryDirectories=[/data/app/com.mypackge-1/lib/arm64, /system/fake-libs64, /data/app/com.mypackge-1/base.apk!/lib/arm64-v8a, /system/lib64, /vendor/lib64]]] couldn't find "libmupdf_java.so"

Thanks!

Password protected pdf

Hi,
I've been looking for an android pdf viewer for more than a year, finally some hope! I was able to load a normal pdf in MuPDFActivity, but when I tried to open a password protected file, the keyboard show up, than the app crash :( So close... The behavior let me think that only a little part is missing. Did I need to configure something or this part haven't been ported yet?

Thanks for your work!

how to build the library

hello my friend,

i want to use mupdf library inside xamarin android project, your binding working very well, thanks a lot for this, but I want to change something inside it, so what I did is I download the source code and change something.

my question is how you build the library and get the .so files?
I want to do that then to make binding for xamarin android

any hint or steps to do it?

thank you

Reflow mode showing blank page with '100%' text

If I use the library in my app with the following code:

MuPDFCore core = new MuPDFCore(this, path);
var reflowView = new MuPDFReflowView(this, core, new Point(parent.Width, parent.Height));
reflowView.SetPage(3, new PointF());
parent.AddView(reflowView);

It only shows a blank page with the text '100%' on the upper left. The same applies if I use MuPDFReaderView:

MuPDFCore core = new MuPDFCore(this, $"{directory}{apiBook.Epub}");
MuPDFReaderView readerView = new MuPDFReaderView(this);
readerView.Adapter = new MuPDFReflowAdapter(this, core);
readerView.SetLayerType(LayerType.Hardware, null);
parent.AddView(readerView);

The type or namespace name 'MuPDFCore' does not exist in the namespace 'Artifex.MuPdf' (are you missing an assembly reference?) (CS0234) (Askaiser.Android.MuPDF)

Error CS0234: The type or namespace name 'MuPDFCore' does not exist in the namespace 'Artifex.MuPdf' (are you missing an assembly reference?) (CS0234) (Askaiser.Android.MuPDF)
