I've been using Mapbox GL Native (specifically react-native-mapbox-gl). I'm generating my own vector tiles on a server, and I'd like to have the user download them onto their device from the mobile app. Then I want Mapbox GL to use the local tiles, specified via a TileJSON file referenced in the Mapbox GL Style file.
I've got it working on iOS (at least in the simulator). My style.json looks like the following:
{
"version":8,
"name":"Bright",
"sources":{
"mapbox":{
"type":"vector",
"url": "asset:///absolute/path/map/tile.json"
}
},
"sprite":"asset:///absolute/path/map/sprites/mysprite",
"glyphs":"asset:///absolute/path/map/glyphs/{fontstack}/{range}.pbf",
"metadata":{...},
"layers":[...]
}
with the tile.json looking like:
{
"tiles":[
"asset:///absolute/path/map/tiles/{z}/{x}/{y}.pbf"
],
"tilejson":"2.0.0",
// plus lots of other stuff
}
On Android this doesn't work. It appears that asset:// only works on files bundled inside the APK, not on the filesystem.
Is there something I can do on the Android platform to let Mapbox GL load my downloaded tiles from off the device?
Have you tried using the file:/// path? This usually loads from your app's file directory, eg.
"file:///absolute/path/map/tiles/{z}/{x}/{y}.pbf"
I am working on an app in Delphi XE8.
When I run the program on my phone, it gives me an error:
Loading bitmap failed(image.png)
My code works as follows:
if ListBox1.ItemIndex = 0 then
begin
img.bitmap.LoadFromFile('Image.png');
iMin:= Round(iNumber * 1);
iMax:= Round(iNumber *13.24);
iAvg:= Round(iNumber * 2.59);
label7.Text:= inttostr(iMin);
label5.Text:= inttostr(iAvg);
label6.Text:= inttostr(iMax);
label2.Text:= 'Minimum';
label3.Text:= 'Average';
label4.Text:= 'Maximum';
end
else
...
Please note the image is saved in the same folder as my program.
Don't use relative paths. Always use absolute paths.
You need to use the Deployment Manager to deploy the image file to an appropriate folder on the phone, and then use the System.IOUtils.TPath class to locate that folder at runtime:
Standard RTL Path Functions across the Supported Target Platforms
On Android, deploy the image file to the ./assets/internal folder, and then use the TPath.GetDocumentsPath() method at runtime, as documented on this blog:
Deploying and accessing local files on iOS and Android
What the EDN documentation and blog both fail to mention is that you also need to add the System.StartupCopy unit to your app's uses clause.
uses
..., System.IOUtils, System.StartupCopy;
...
img.bitmap.LoadFromFile(TPath.Combine(TPath.GetDocumentsPath, 'Image.png'));
I'm using Dojo 1.10 and i try to solve all the problemas with undescore files (_blabla). related here: https://code.google.com/p/android/issues/detail?id=5343
building/minimizing dojo for specific webkit:
http://dojotoolkig.org/reference-guide/1.10/build/webkit-mobile.html#build-webkit-mobile and everything works fine excepts Carousel and Accordion, this elements loads fine on local webserver.
I try to debug with weinre and this "classes" Carousel, Accordion doesn't exists (object dojox.mobile doesn't contain this)
Anyone can provide me with a glimmers of hope
iOS and webbrowsers works fine, I'm using Cordova 4.0 (only JS, CSS, HTML)
Tested on Physical and virtual devices
Should not have the _ problems, All the widgets you need, including Carousel are compiled into the layer files..(Carousel is inside of mobile-ui-layer.js)
In your www folder there should be either mobile-ui-layer.js and core-web-layer.js
files in either the layers or dojo subdirectory.
and your wlCommonInit has to be referencing these files depending on where they are in your project:
function wlCommonInit() {
require([ "layers/core-web-layer", "layers/mobile-ui-layer" ], dojoInit);
}
Edit, sorry just noticed that you are saying you are using straight cordova and not worklight.
They easiest say to deal with this is to use the dojo build, to condense the dojo files into a layer file.
Download -src.zip package from dojo website
extract new dojo
navigate to /js/dojo-src/util/buildscripts/profiles
use one of the existing profiles as template. insert something like i have below as a layer.
run ./build.sh -p ./profiles/.profile.js
Add Layer file to project and reference it.

I'm using Cordova 3.5 to build an app which contains a menu with pretty standard items in the list (home, contacts, etc.), and I want to use the native menu icons whenever possible. I believe those icons are already on the device as part of the OS, but I don't know if Cordova gives me a way to reference them.
I suppose I'd need to write a Javascript function to choose the right file name based on the platform, e.g.:
// this is pseudocode
var icon = '';
if (platform === 'android') {
icon = 'some/path/home.png';
} else {
icon = 'other/path/icon.home.png';
// or maybe a function such as the following exists:
// icon = cordova.getNativeIcon('icon.home.png');
}
$('.selector').css('background-image', icon);
Alternatively, I may be able to make do by referencing the files in CSS, e.g.:
.android .home-icon {
background-image: url('some/path/home.png');
}
.ios .home-icon {
background-image: url('other/path/icon.home.png');
}
So, how do folks handle this sort of thing in Cordova? Is there a function I can use to access native icons? Are folks just copying them into their projects? What's the best practice?
If you're working with Cordova, then you'll be working inside a web view provided by the host OS and you won't have direct access to any artwork. I've found that using icon fonts and CSS "themes" to work well enough, but that approach will replicate artwork already provided. There's extra work involved with theming for iOS 6 vs iOS 7 or 8, for example, but it's not as bad as it sounds.
IBM does have an article on partitioning your view between native and web controls, but it sounds a bit cumbersome. More details here: https://www.ibm.com/developerworks/community/blogs/worklight/entry/ios_combining_native_and_web_controls_in_cordova_based_applications
I am using AngularJS with Trigger.io to develop a mobile application for both iOS and Android.
When I try to open a link that looks like this:
<a ng-href="#/offers/{{featured_offer.Id}}"></a>
It works perfectly fine on iOS, but on Android I get this message in the trigger console, and the link is not navigated to:
[WARNING] Attempted to open a URL which could not be handled: unsafe:content://io.trigger.forge722b6464a0e211e2ba9d12313d00dc45/src/index.html#/offers/8
How can I get this to work in Android the same as it works in iOS?
Looks like Angular adds unsafe: to url schemes it doesn't recognise, I think you want to include something like:
app.config(function($compileProvider){
$compileProvider.urlSanitizationWhitelist(/^\s*(https?|ftp|mailto|file|tel|content):/);
});
Which adds content: to the accepted url schemes.
I had this same problem, specifically with trying to display an img with a src of a file returned by forge.file.getImage. Angular adds unsafe: to the content: prefix of the local img URL, and as connorhd said, you need to add content: to the url whitelist.
Note that compileProvider's API has changed with recent versions of Angular, so I'm commenting here in case anyone else finds an updated version of this workaround useful.
app.config(['$compileProvider',
function($compileProvider) {
$compileProvider.imgSrcSanitizationWhitelist(/^\s*(https?|ftp|mailto|file|tel|content|blob):|data:image|/);
// note: you'll also have to do imgSrcSanitizationWhitelist if you want to use general links as well as ng-src on images.
}]);
I too had this problem just add sanitizer in you config.xml
var app = angular.module( 'myApp', [] )
.config( [
'$compileProvider',
function( $compileProvider )
{
$compileProvider.aHrefSanitizationWhitelist(/^\s*(https?|ftp|mailto|chrome-extension):/);
// Angular before v1.2 uses $compileProvider.urlSanitizationWhitelist(...)
}
]);
