We are developing a markdown editor plugin for eclipse. My colleagues who are using Windows 10 encounter a bug that causes keys to stop working. The most common key is delete, other times it is ctrl + s.
Here is the code for the editor extension:
public class MarkdownEditor extends AbstractTextEditor {

public MarkdownEditor() throws FileNotFoundException {
setSourceViewerConfiguration(new TextSourceViewerConfiguration());
setDocumentProvider(new TextFileDocumentProvider());
// Activator manages connections to the Workbench
activator = Activator.getDefault();
markdownRenderer = new MarkdownRenderer();
}
private IFile saveMarkdown(IEditorInput editorInput, IDocument document, IProgressMonitor progressMonitor) {
IProject project = getCurrentProject(editorInput);
String mdFileName = editorInput.getName();
String fileName = mdFileName.substring(0, mdFileName.lastIndexOf('.'));
String htmlFileName = fileName + ".html";
IFile file = project.getFile(htmlFileName);
String markdownString = "<!DOCTYPE html>\n" + "<html>" + "<head>\n" + "<meta charset=\"utf-8\">\n" + "<title>"
+ htmlFileName + "</title>\n" + "</head>" + "<body>" + markdownRenderer.render(document.get())
+ "</body>\n" + "</html>";
try {
if (!project.isOpen())
project.open(progressMonitor);
if (file.exists())
file.delete(true, progressMonitor);
if (!file.exists()) {
byte[] bytes = markdownString.getBytes();
InputStream source = new ByteArrayInputStream(bytes);
file.create(source, IResource.NONE, progressMonitor);
}
} catch (CoreException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return file;
}
private void loadFileInBrowser(IFile file) {

IWorkbenchPart part = site.getPart();
site.getPage().activate(part);
} catch (IOException | PartInitException e) {

}
#Override

Before adding viewmodel & livedata , i successfully implemented infinity scroll with retrofit. But after adding viewmodel & livedata with Retrofit, My can't update recyclerview with new data call or viewmodel observer not update the list.
I simply want to infinite scrolling as my code does before. I add a global variable to reuse next page token. Am i missing anything or any sample to implement infinite recyclerview with viewmodel & retrofit will be awesome.
public static String NEXT_PAGE_URL = null;
I coded like that.
My Activity -> PlaceListActivity
placeRecyclerView.addOnScrollListener(new RecyclerView.OnScrollListener() {
#Override
public void onScrollStateChanged(RecyclerView recyclerView, int newState) {
super.onScrollStateChanged(recyclerView, newState);
LogMe.d(tag, "onScrollStateChanged:: " + "called");
// check scrolling started or not
if (newState == AbsListView.OnScrollListener.SCROLL_STATE_TOUCH_SCROLL) {
isScrolling = true;
}
}
#Override
public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
LogMe.d(tag, "onScrolled:: " + "called");
super.onScrolled(recyclerView, dx, dy);
currentItem = layoutManager.getChildCount();
totalItems = layoutManager.getItemCount();
scrolledOutItems = ((LinearLayoutManager) recyclerView.getLayoutManager()).findFirstVisibleItemPosition();
LogMe.d(tag, "currentItem:: " + currentItem);
LogMe.d(tag, "totalItems:: " + totalItems);
LogMe.d(tag, "scrolledOutItems:: " + scrolledOutItems);
if (isScrolling && (currentItem + scrolledOutItems == totalItems)) {
LogMe.d(tag, "view:: " + "finished");
isScrolling = false;
if (ApplicationData.NEXT_PAGE_URL != null) {
LogMe.d(tag, "place adding:: " + " onScrolled called");
ll_loading_more.setVisibility(View.VISIBLE);
// todo: call web api here
callDataFromLocationAPi(type, ApplicationData.NEXT_PAGE_URL, currentLatLng);
} else {
LogMe.d(tag, "next_page_url:: " + " is null");
}
}
}
});
private void callDataFromLocationAPi(String type, String next_page_url, LatLng latLng) {
if (Connectivity.isConnected(activity)) {
showProgressDialog();
model.getNearestPlaces(type, next_page_url, latLng).

I precise code due to question simplicity.
Though you already use android-jetpack, take a look at Paging library. It's specially designed for building infinite lists using RecyclerView.
Based on your source code, I'd say that you need PageKeyedDataSource, here is some example which includes info about how to implement PageKeyedDataSource -
7 steps to implement Paging library in Android
If talking about cons of this approach:
You don't need anymore to observe list scrolling (library doing it for you), you just need to specify your page size in the next way:
PagedList.Config myPagingConfig = new PagedList.Config.Builder()
.setPageSize(50)
.build();
From documentation:
Page size: The number of items in each page.
Your code will be more clear, you'll get rid of your RecyclerView.OnScrollListener
ViewModel code will be shorter, it's will provide only PagedList:
#NonNull
LiveData<PagedList<ReviewSection>> getReviewsLiveData() {
return reviewsLiveData;
}

I am using OSMdroid to display both online and offline data in my app. The offline data are stored in a .zip file with the required structure.
Is it possible to have these offline tiles stored in a directory (extracted .zip file with the same structure)?
Could somebody please tell me how could I achive this?
Thank you.
I am sorry. I should try more before asking. But I am leaving this question here, somebody could find it useful.
Solution:
New MapTileFileProvider. I called it MapTileFileFolderProvider, it is a lightly modified MapTileFileArchiveProvider. It is using folders instead of archives. The modifications are not perfect, it is a "hot solution" that needs someone more experienced in Java/Android to make it properly.
Benefits from loading Tiles from folders:
Faster loading of tiles (I know, I won't recognize the difference).
Easier updates focused only on changed tiles not whole map plans.
Application can download tiles when is in "online mode" and then use the downloaded Tiles offline.
MapTileFileFolderProvider - only modifications

Well, as far as I understand what you are trying to get... this is more or less what the standard XYTileSource is already doing.
So if you simply use a ready-to-use tile source like this one:
map.setTileSource(TileSourceFactory.MAPNIK);
you will see downloaded tiles files stored in /sdcard/osmdroid/tiles/Mapnik/
The main difference is that it adds a ".tile" extension at the end of each tile file (probably to prevent tools like Android gallery to index all those images).
If you have a ZIP file with tiles ready to use, you could extract them in this directory, and add .tile extension to each tile (355.png => 355.png.tile)
And TileSourceFactory.MAPNIK will be able to use them.

This part of code in your app will get executed - if device acts as client
and
final File f = new File(Environment.getExternalStorageDirectory() + "/"
+ "Wifidirect" + "/" + fileName);
this part of code in your app will get executed - if device acts as server (in this case GO) but fileName is always null
Since filename is initialized to "null" , on the server device this will be null.
FileServerAsyncTask is created only on GO( server ) as per the code.
In android sample code file transfer is working only from client to server. In this code user can do file sharing in both directions i.e client to server as well as server to client.
You can see this link.
How can I transfer files between Android devices using Wi-Fi Direct?
