Blank pages + JS error (getPaginationInfo)

[fzaiatz]

Just cloned the latest versión of the SDK launcher for Android, built it, and everything seems to be working as expected.

ePubs are being loaded (I can see the TOC loaded for a couple of ebooks), but they never show (I'm sending data through Intent to WebViewActivity). All I see is a blank page, the prev and next buttons at the bottom, and when I click on them, this error appear in LogCat:

• Uncaught TypeError: Cannot call method 'getPaginationInfo' of undefined at file:///android_asset/readium-shared-js/js/views/reader_view.js:192

Before that, here's some output from the logs:

• Trying to load lib APP_PATH/libepub3.so 0xa641dc80

@fzaiatz can you try the build of the SDKLauncher that I uploaded to my fork of the project and see if it has the same problem?

Also, if you could share the file you are testing with it would be appreciated! (not sure where to put it though) You can also use the epub validator to make sure it is an EPUB that conforms to the specification.

@datalogics-bhaugen thanks for the quick response :)

I've downloaded your fork, and compared with the source from the latest version in git, and I couldn't find any differences at all (at least in the SDKLauncher-Android project, as the references to the other modules are empty).

I've downloaded the apk from your fork, and it's working as expected in the simulator/device with the ebooks I'm trying to show in my app (they are passing epub validation successfully).

Here's how I'm trying to load and show each ebook:

Intent in = new Intent(getActivity(), WebViewActivity.class);
Container bookContainer = EPub3.openBook(Environment.getExternalStorageDirectory().getAbsolutePath()+ "/Download/TEST.epub");
ContainerHolder.getInstance().put(bookContainer.getNativePtr(), bookContainer);
in.putExtra(Constants.CONTAINER_ID, bookContainer.getNativePtr());

NavigationTable navigationTable = getNavigationTable(bookContainer);
List navigationElements = flatNavigationTable(navigationTable, new ArrayList());
NavigationPoint point = (NavigationPoint) navigationElements.get(0);
try {
String jsonData = OpenPageRequest.fromContentUrl(point.getContent(), navigationTable.getSourceHref()).toJSON().toString();
in.putExtra(Constants.OPEN_PAGE_REQUEST_DATA, jsonData);
} catch (JSONException e) {
e.printStackTrace();
}

in.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(in);

...

private NavigationTable getNavigationTable(Container container) {
NavigationTable navigationTable = null;
if (container.getDefaultPackage() != null) {
navigationTable = container.getDefaultPackage().getTableOfContents();
}
return (navigationTable != null) ? navigationTable : new NavigationTable("toc", "", "");
}

private List flatNavigationTable(NavigationElement parent, List list) {
for (NavigationElement ne : parent.getChildren()) {
list.add(ne);
flatNavigationTable(ne, list);
}
return list;
}

Sorry if I made it sound like my fork was different. It should be exactly the same.

This is what I was trying to point you at so I am glad you found it. Does the SDKLauncher when you build it for yourself work?

Is this just a problem when you try and use the Readium code in your application?

[fzaiatz]

@datalogics-bhaugen solved!

I forgot to copy the contents of the assets folder (readium-shared-js) from the SDKLauncher project to mine. I'm using the launcher project as a library, so basically the assets didn't exist in the generated apk.

Thanks again for your help :)

@fzaiatz is this issue ready to be closed then?

[fzaiatz]

@datalogics-bhaugen that's right :)
