I'm trying to get route-me to show an offline map which is bundled or to be downloaded after app installation. I'm using route-me bindings sample project to get the work done just for now. I also use the mbtiles file from the original route-me repo's SampleMap project. I copy the file to project's root directory and set it's build action to BundleResource (that's what I thought would be appropriate). After that I changed to code to this :
public override void ViewDidLoad ()
{
base.ViewDidLoad ();
RMDBMapSource dbSource = new RMDBMapSource ("Philadelphia.mbtiles");
MapView = new RMMapView(View.Frame, dbSource.Handle);
MapView.AutoresizingMask = UIViewAutoresizing.FlexibleDimensions;
if (UIScreen.MainScreen.Scale > 1.0)
MapView.AdjustTilesForRetinaDisplay = true;
Add (MapView);
}
But no luck. App runs in the simulator but showing only a grey background nothing more. So I need someone to help me and tell me what I'm doing wrong. I need to get it done this week since next week is the deadline for project. So any help would be appreciated.
I haven't actually used offline tiles myself, but based on this thread it looks like you might need to put the RMDBMapSource into an instance of RMMapContents instead of directly into the MapView. So I'm thinking it would be something like this with Xamarin:
RMDBMapSource dbSource = new RMDBMapSource ("Philadelphia.mbtiles");
MapView = new RMMapView(View.Frame, new IntPtr());
RMMapContents contents = new RMMapContents (MapView.Handle, dbSource.Handle);
That assumes you have a wrapper binding for RMMapContents too which from the looks of it the bindings project does not have by default. You'd need to throw in a wrapper that at least defines the constructor.
This page looks like it provides similar code (in Obj-C) towards the bottom.

I've been reading a lot of StackOverflow posts that discuss copying data from FileSystemStorage to Storage in CodenameOne, such as described in this answer from Shai, as seen below:
InputStream stream =
FileSystemStorage.getInstance().openInputStream(i);
OutputStream out =
Storage.getInstance().createOutputStream("MyImage");
Util.copy(stream, out);
Util.cleanup(stream);
Util.cleanup(out);`
I've been trying to do the reverse: save from Storage to FileSystemStorage in order to show a PDF in the BrowserComponent (while using iOS), but have not been able to do so. I need to show the PDF within the app (so I don't want to use Display.getInstance().execute()).
Basically, I'm trying to dynamically populate a Container with whatever files the user selects-- I am using the FileChooser library for CN1 from Steve Hannah. (Disclaimer: I have made slight modifications to this library as it used in the app I'm working on-- HOWEVER, when I choose images with this library and pull them from Storage to an Image via InputStream, they display perfectly in an ImageViewer so I know that all files are being saved correctly in Storage.)
Here is my code (with help from Steve Hannah's comment on GitHub):
//fileLocation and fileName are slightly different but both end with file extension
File file = new File(fileToUpload.getFileName());
FileSystemStorage fss = FileSystemStorage.getInstance();
InputStream is = Storage.getInstance().createInputStream(fileToUpload.getLocation());
OutputStream os = fss.openOutputStream(file.getAbsolutePath());
Util.copy(is, os);
ToastBar.Status status = ToastBar.getInstance().createStatus();
String message = file.exists() + " " + file.isFile() + file.getAbsolutePath();
status.setMessage(message);
status.setExpires(3000);
status.show();
NativeLogs.getNativeLogs();
if (Display.getInstance().getPlatformName().equals("ios")) {
//Log.p("in ios !!!!");
BrowserComponent browserComponent = new BrowserComponent();
browserComponent.setURL(file.getPath());
horizontalContainer.add(browserComponent);
}
The ToastBar displays true and true for file.exists() and file.isFile().
I stipulate iOS because as far as I've seen while researching previewing PDFs within an app, I've seen that Android needs to have a different implementation, like adding a NativeInterface with an Android library. I also saw in different answers on the Google Group that this functionality (using browserComponent to view PDFs) is only available for iOS and not on the simulator. In the simulator, I see a blank space. My iPhone just freezes and/or crashes after displaying the ToastBar (and I work on a Windows machine, so not much ability to see native logs....)
What can I do to access the file and show it in the BrowserComponent?
Thank you!
Simple solution -- the file had a space in it (eg. "Test page.pdf") and didn't show! When I used files that didn't have spaces this worked and after removing spaces in the file names, thankfully everything worked. I'll have to add code to handle this scenario.
Thanks for your help!
So I have app where I want to let users to share screenshot of score to facebook etc... I'm using SocialShare widget. In documentation it says to set path to image like this: "image:fileToShare.nativePath", but I'm not really sure how to set it. Another problem is that I need to share picture that has always different name, it saves screenshots with names like tia7828157.png,tia107997596.png... in folder in device internal memory in pictures/enigmania/ I'm new to appcelerator, so I dont know if there is something like wildcard I could use for this? Thanks for any help.
This is my code so far which I know is wrong, I know the widget works because it shares text without problem:
function shareTextWidget(e){
// share text status
var socialWidget=Alloy.createWidget('com.alcoapps.socialshare');
socialWidget.share({status:"Enigmania kvíz",androidDialogTitle:"hoho",image:test.png/pictures/enigmania});
}
You should use Ti.Filesystem class methods/properties to get the path of any file located on internal or external storage.
Also aware of the permissions of reading storage on Android 6+. Use Storage Permissions before accessing any file on Android 6+.
Simple code snippet to create a directory on internal storage at this location: pictures/enigmania and then write an image file of captured view in this directory.
function shareTextWidget(e){
var directory = Ti.Filesystem.getFile(Ti.Filesystem.externalStorageDirectory, 'pictures/enigmania');
!directory.exists() && directory.createDirectory();
var fileToShare = Ti.Filesystem.getFile(directory.resolve(), 'screen.jpg');
fileToShare.write($.SCREENSHOT_VIEW.toImage()); // write the blob image to created file
var socialWidget=Alloy.createWidget('com.alcoapps.socialshare');
socialWidget.share({status:"Enigmania kvíz",androidDialogTitle:"hoho",image:fileToShare.nativePath});
}
This code should work without any issues.
Note that $.SCREENSHOT_VIEW is the View ID for which you will take screenshot, so it depends on you how you maintain your View positions in order to capture correct screenshot, but point is to use Ti.UI.View toImage() method to capture the screenshot of particular view.
Let me know if this works for you or not, else we can look into other methods by getting your exact requirements. Good Luck!!!!
I would like to be able to redirect my logging statements to a file so that I can retrieve them when my app runs standalone (i.e. is not attached to Xcode). I have discovered (thank you Stackoverflow) that freopen can be used to accomplish this.
If I create a new Xcode project and add the code to redirect stderr then everything works as expected.
However, when I add the redirection code to my existing, bluetooth project I am having trouble. The file is being created and I can retrieve it using iTunes or Xcode's Devices window, but it is of size 0. If I explicitly close the file then the text that I wrote actually makes it into the file. It is as though iOS is not flushing the file when the app is terminated. I suspect that the trouble stems from the fact that I have enabled background processing. Can anyone help me to understand this?
Here is my code:
let pathes = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true);
let filePath = NSURL(fileURLWithPath: pathes[0]).URLByAppendingPathComponent("Test.log")
freopen(filePath.path!, "a", stderr);
fputs("Hello, Samantha!\r\n", stderr);
struct StderrOutputStream: OutputStreamType {
static let stream = StderrOutputStream()
func write(string: String) {fputs(string, stderr)}
}
var errStream = StderrOutputStream.stream
print("Hello, Robert", toStream: &errStream)
fclose(stderr) // Without this the text does not make it into the file.
I'd leave this as a comment, but have you looked into NSFileHandle? It sounds like you just need a way to append data to the end of a text file, correct?
Once you have a handle with something like NSFileHandle(forWritingToURL:), you can use .seekToEndOfFile() and .writeData(_:). As a side note, you'll need to convert your String to Data before writing it.
Admittedly, this will probably end up being more lines of code, and you'll almost certainly need to take threading into consideration.
We have a strange behavior with the WinRT Geolocator in one of our app. The user clicks on a button in the app to get the current position. Works fine the first time but all subsequent click on the button returns the same coordinates even tough we move for more than one kilometer.
The application runs on a ThinkPad and we've installed an application called "GPS Satellite" and if we switch to this application, get a coordinates, and return to our app then the Geolocator returns the correct coordinates. So we know the GPS is working fine, but seems like the coordinates are kept in cache even tough we've set a expiration of a few millisecond.
private async void ExecuteObtenirCoordGPSCommand()
{
try
{
Geolocator geolocator = new Geolocator();
geolocator.DesiredAccuracy = PositionAccuracy.High;
// Make the request for the current position
Geoposition pos = await geolocator.GetGeopositionAsync(new TimeSpan(0,0,0,0,200), new TimeSpan(0,0,5));
Place.Latitude = pos.Coordinate.Latitude;
Place.Longitude = pos.Coordinate.Longitude;
}
catch
{
GPSMsgErreur = "The GPS is unavailable";
}
}
We've tried to put a expiration on the method GetGeopositionAsync but it didn't solved the problem.
We've tried to put the Geolocator var at the class level with the same result.
Any ideas?
Not sure if this is your issue but the API you are using is tagged has obsolete in this post:
http://msdn.microsoft.com/en-us/library/windows/apps/windows.devices.geolocation.geocoordinate
Try using:
Place.Latitude = pos.Coordinate.Point.Position.Latitude;
Place.Longitude = pos.Coordinate.Point.Position.Longitude;
You may also use:
double someVar = pos.Coordinate.Accuracy
to figure out what is the margin of error on the device. May be you where not far enough from your first location and your second location was within the margin of error...
I can also tell you that I have a software built with Visual Studio 2013 Windows (WinRT) that runs on a ThinkPad using the same objects you are using and it works fine.
The main difference between mine and yours is that I am using the API showed above and that I did not use the following statement:
geolocator.DesiredAccuracy = PositionAccuracy.High;
And that I did not pass any parameters to the GetGeopositionAsync method.
I hope this helps.
Cheers, Hans.
Why do I get a black screen when I generate Lua code from the newest version (1.4.7) of LevelHelper My Old Level files work with my code and it generated only one lua file. The new one generates a set of 10-12 files, and leaves me with a black screen on the Corona simulator.
Am I doing anything drastically wrong?
Has the use of Level Helper changed with the new version?
All the tutorials and blogs I checked are showing the use of the old LevelHelper. any repositories / github links you would like to point me to?
For everybody else who has this problem, your config.lua file must look something like this
application =
{
content =
{
fps = 60,
width = 320,
height = 480,
scale = "letterbox",
imageSuffix =
{
["-hd"] = 2
}
},
LevelHelperSettings =
{
imagesSubfolder = "Images",
levelsSubfolder = "Levels",
directorGroup = nil
}
}
Have you seen this?
http://www.levelhelper.org/?page_id=1596
And also the latest tutorial for Corona SDK that talk LevelHelper 1.4
http://www.levelhelper.org/?p=1821
While the old LevelHelper was generating only one lua file - the new one generated multiple files because it added many complex features that could not be encapsulated in only one lua file.
Also, i want to stress that if you want fast response you should mail me or write to the LevelHelper forum.
I can help you out with your code and what you're doing wrong if you show me how you load the level.
Since you probably load it as the old way you should read the Getting Started chapter in the API Documentation.
You are probably missing the config.lua settings.
