I have an application in Xamarin crossplatfrom. I created a solution for localize strings and it is working perfect. I am setting:
StringResources.Culture = DependencyService.Get<ILocalize>().GetCurrentCultureInfo();
But I have a problem with image resoruces. I created folders in android app:
drawable, drawable-pl-rPL, drawable-pl-rPL-hdpi, drawable-pl-rPL-ldpi, drawable-pl-rPL-mdpi
But I have no idea how to set global culture for app. I was trying to put in MainActivity class:
var ci = new System.Globalization.CultureInfo(lastLanguage);
Thread.CurrentThread.CurrentCulture = ci;
Thread.CurrentThread.CurrentUICulture = ci;
Where lastLanguage is a code for lasdt selcted language (en or pl-PL). But it is not working, image is always taken from drawable folder, no from drawable-pl-rPL
Can you help me somehow?

Im trying to do this for a shared application in Xamarin. In the iOS section is looks like:
var window = UIApplication.SharedApplication.KeyWindow;
var vc = window.RootViewController;
var user = await auth0.LoginAsync(vc, withRefreshToken: true);
but for android I have no idea how to implement the view controller 'vc' to pass to LoginAsync().
You can always refer to https://auth0.com/docs/quickstart/native/xamarin. In Android referring this will give the current context you are in. this context is very much similar to window.RootViewController for iOS. So all you need to do is calling
var user = auth0.LoginAsync(this, withRefreshToken: true);
If you want to show the login in other window for android, get the context and assign it to a Android.App.Application.Context type variable and replace this with the variable in the previously mentioned code.
I have an native iOS sample app installed in my iPad and also my sample xamarin.Forms App installed. I want to open native iOS app from Xamarin.forms when clicked on button. I have set URL schema in my native iOS app in info.plist.
How do I open native app from xamarin.forms on click of a button. I already tried
var request = Device.OnPlatform(
string.Format("native app url"),
string.Format("native app url"),
string.Format("native app url"));
Device.OpenUri(new Uri(request));
but its not working.
It's basically how you are doing it.
var url = Device.OnPlatform(iOSUrl, androidUrl, winPhoneUrl);
Device.OpenUri(new Uri(request));
Be aware that each platform have some requirements in the way to url is configured and parameters are sent.
Let say to get the maps app open in each platform you would use these urls schemes:
// iOS doesn't like %s or spaces in their URLs, so manually replace spaces with +s
var iOSUrl = string.Format("http://maps.apple.com/maps?q={0}&sll={1}", name.Replace(' ', '+'), loc);
var androidUrl = string.Format("geo:0,0?q={0}({1})", string.IsNullOrWhiteSpace(addr) ? loc : addr, name);
var winPhoneUrl = $"bingmaps:?cp={loc}&q={name}";
var url = Device.OnPlatform(iOSUrl, androidUrl, winPhoneUrl);
Also you cannot open any arbitrary app unless you know its Url scheme.
Anyway, if the Device.OpenUri() doesn't fulfill your requirements you are good to create your own implementations using the native APIs.

I am using below code in xamarin forms
NSUrl request = new NSUrl("Camera://");
var canOpen = UIApplication.SharedApplication.CanOpenUrl(new NSUrl(request.ToString()));
if (!canOpen)
{ Task.FromResult(false); }
else
{
Task.FromResult(UIApplication.SharedApplication.OpenUrl(new NSUrl(request.ToString())));
}
I'm trying to use https://developer.xamarin.com/api/member/Xamarin.Forms.Application.OnAppLinkRequestReceived/p/System.Uri/ but can't seem to get it to be called in any way.
Did anyone ever tried to implement this new method?
I've tried several ways to implement different deeplinks, all of them open the app fine so they're correctly configured but that method never gets called.
Thanks.
This is how I set it up in Android.
Put this above your MainActivity.cs
[IntentFilter(new[] { Android.Content.Intent.ActionView },
Categories = new[]
{
Android.Content.Intent.CategoryDefault,
Android.Content.Intent.CategoryBrowsable
},
DataScheme = "http",
DataPathPrefix = "/tesla/",
DataHost = "exrin.net")]
This registers the activity when the app is installed. Change the URL to your desired URL.
For Android only (no need to do this with iOS) you need to also install the Nuget Xamarin Forms AppLinks
In your OnCreate make sure you do this after your Xamarin Forms Init
AndroidAppLinks.Init(this);
Then when you load the URL in a browser (in my example http://exrin.net/tesla) you will get this:
Then if you open the app it will enter here with the full URL as the URI parameter. This is in the App.cs (Xamarin.Forms.Application)
protected override void OnAppLinkRequestReceived(Uri uri)
{
base.OnAppLinkRequestReceived(uri);
}
You can then decode the URI as you see fit to move to the specific page in your app that the URL relates to/
More details at Xamarin Forms AppLinks
Also, your MainActivity must be derived from FormsAppCompatActivity for it to work. Once I changed it to that from FormsApplicationActivity, it started working.
I want the user to choose his language in my app so if he chooses a different Language (because he wants to test his skills in other languages) than the Phone default language, I want all my globalized Strings to be changed during runtime.
Is there the possibility to override the culture Info in c# for wp7 or wp8 for the runtime of current app?
In App.xaml.cs, in the InitializePhoneApplication method:
private void InitializePhoneApplication()
{
Thread.CurrentThread.CurrentCulture = new CultureInfo("fr-FR");
Thread.CurrentThread.CurrentUICulture = Thread.CurrentThread.CurrentCulture;
.......
}
Be sure to edit you .csproj project file to set support for the languages you want to use in the SupportedCultures tag:
<SupportedCultures>en;fr-FR</SupportedCultures>
I've been trying to implement this example using C# and Monodroid, but am having difficulties reading and writing an Asset file:
http://docs.xamarin.com/android/advanced_topics/using_android_assets
I am using the emulator, not a device.
First of all, I am having trouble finding the namespace for Assets.Open. What I ultimately found was
const string lfn = MyAssetFile.txt;
System.IO.StreamReader(Android.Content.Res.Resources.System.Assets.Open(lfn);
Is this the correct namespace?
Second of all, my Asset file is marked as AndroidAsset and "Copy Always" in the VS "Properties" pane, but my attempts to read the file always fail (File Not Found) using this statement:
string settings = "";
using (StreamReader sr = new System.IO.StreamReader (Android.Content.Res.Resources.System.Assets.Open(lfn))) settings = sr.ReadToEnd();
Do I have my VS settings wrong so that the asset file not being copied onto the emulator, or is it being copied OK but my code to open/read it is wrong?
You must use:
const string lfn = "MyAssetFile.txt";
string settings = string.Empty;
// context could be ApplicationContext, Activity or
// any other object of type Context
using (var input = context.Assets.Open(lfn))
using (StreamReader sr = new System.IO.StreamReader(input))
{
settings = sr.ReadToEnd();
}
If I remember correctly, as I haven't got an IDE at the moment, Android.Content.Res.Resources.System.Assets references the Android assets not your project assets. You want to use your projects assets so you need to use the AssetManager from your Activities or Contexts.
For example: the Activity class has a property called Assets. This is what you use. OR you use a View's Context.Assets property.
Or just simply add at the top:
using System.IO;
and it will work.
Xamarin team forget sometimes to mention using stuff.
