I've got an {N} app with an Android specific call.
intent.putExtra( "variable", 123 );
It looks like {N} is using the putExtra(String,double) overload.
How can I force it to the putExtra(String,int) overload.
Thanks.
You can use java.lang.Integer from native code for this
intent.putExtra( "variable", new java.lang.Integer(123) );

I'm developing an app using Xamarin's HCE feature.
The project structure is as follows.
hceSample
hceSample.Android
hceSample.iOS
I am implementing hce simulation code called hceService in hceSample, not hceSample.Android.
A function called Enable_Card exists in the hce service, and you want to use the NfcFCardEmulation.EnableService function in that function.
Activity and ComponentName are requested as parameters of the function.
The ComponentName area was handled easily, but I don't know how to get the Activity. Please advise.
This is the contents of enable_Card function of hceService.
private Activity activity = null;
private bool enable_Card(cardModel card)
{
try
{
sid = card.cardSN;
tag = "Felica";
emulation.EnableService(, componentName); //<- How to get Activity??
emulation.SetNfcid2ForService(componentName, sid);
return true;
}
catch
{
return false;
}
}
This is my first time asking a question on Stackoverflow.
I would appreciate it if you could point out any missing or incorrect parts.
I trying this
activity = Xamarin.Essentials.Platform.CurrentActivity; //<- this function is not found!
Added missing information!
The namespace of the Enable_Card function is located in hceSample.Service.
Are you using the NfcFCardEmulation.EnableService(Activity, ComponentName) Method, right?
The method is an android api from android sdk,you cannot use it directly in xamarin.form(yours is hceSample) project.
If you want to call the function in xamarin form project(hceSample) from native platform(hceSample.Android, or hceSample.iOS),you can use Xamarin.Forms DependencyService to achieve this.
The DependencyService class is a service locator that enables Xamarin.Forms applications to invoke native platform functionality from shared code.
For more information about DependencyService, you can check document Xamarin.Forms DependencyService. And there is a sample included in above document,which is helpful for you to understand DependencyService.
Note:
We recognize that hardware service is the right and ideal way to
implement in each OS project. However, I'm curious if there is a way
to code Android and iOS at the same time
Since the api you used is from android sdk, you can call it in native android or use DependencyService to call it on xamarin.form(yours is hceSample) project.
If you call it on xamarin.form(yours is hceSample) project, you also need to find the the corresponding function or interface in iOS.
I'd like to render GraphQL Playground as a React component in one of my pages but it fails due to missing file-loader in webpack. Is there a way to fix this in docs or do I need to create new plugin with new webpack config?
Is it good idea to integrate Playground and Docusaurus at all?
Thanks for your ideas...
A few Docusaurus sites have embedded playgrounds:
Hermes
Uniforms
In your case you will have to write a plugin to extend the webpack config with file-loader.
Not sure if you found a better way but check out: https://www.npmjs.com/package/graphql-playground-react
You can embed this react component directly in your react app - It looks like Apollo also uses the vanilla JS version of this
I just had exactly the same problem. Basically, Docusaurus with a gQL Playground Integration runs fine in local but won't compile due to errors when running yarn build as above.
In the end I found the answer is in Docusaurus, not in building a custom compiler:
I switched from using graphql-react-playground to GraphiQL: package: "graphiql": "^1.8.7"
This moved my error on to a weird one with no references anywhere on the web (rare for me): "no valid fetcher implementation available"
I fixed the above by importing createGraphiQLFetcher from '#graphiql/create-fetcher' to my component
Then the error was around not being able to find a window component, this was an easy one, I followed docusaurus docs here: https://docusaurus.io/docs/docusaurus-core#browseronly and wrapped my component on this page in like this:
import BrowserOnly from '#docusaurus/BrowserOnly';
const Explorer = () => {
const { siteConfig } = useDocusaurusContext();
return (
<BrowserOnly fallback={Loading...}>
{() => {
const GraphEx = GraphExplorer
return
}}
);
}
This now works and builds successfully
Using xamarin ui test For Android app
"app.Query(c=>c.Id("chkbox").Invoke("isChecked").Value()).First()". Assuming "chkbox" is the id for the checkbox. Is working fine
But for iOS app how to verify check box is checked or not? or Native method of iOS to check box is checked or not?
Thanks in advance
I belive that you want to check the isOn property of UISwitch, so something like below should work:
app.Query(c=>c.Id("chkbox").Invoke("isOn").Value()).First()
This actually works, returning 1 or more AppResults if successful:
To check if set:
app.Query(c => c.Switch("chkBox").Property("isOn",true))
To check if NOT set:
app.Query(c => c.Switch("chkBox").Property("isOn",false))
You could use the query part in a WaitForElement if you wanted the test to fail at this point:
app.WaitForElement(c => c.Switch("chkBox").Property("isOn", true), "chkBox is unchecked!");
We are implementing a server for app distribution and we need restrict the access to the apps by:
mac address
ip
At the moment I have not found any module that can obtain this data from the device in nativescript, so i don't know if there's a plugin or how else can I achieve this.
In nativescript you can access native apis of device
so if there isn't any module/plugin for it you can use this option for accessing native apis.
https://docs.nativescript.org/core-concepts/accessing-native-apis-with-javascript
for example there is solution for mac adress here
in JAVA:
WifiManager wifiManager = (WifiManager) getSystemService(Context.WIFI_SERVICE);
WifiInfo wInfo = wifiManager.getConnectionInfo();
String mac = wInfo.getMacAddress();
we can write it in javascript like this:
first we should fine where is this getSystemService:
after searching in documentation of android we found:
getSystemService is in android.content.Context
for accessing context in nativescript http://docs.nativescript.org/cookbook/application
we can do:
import app = require("application");
app.android.context;
so let's write it in javascript:
we don't have types in javascript so we use var instead;
var context = android.content.Context;
var wifiManager = app.android.context.getSystemService(context.WIFI_SERVICE);
var wInfo = wifiManager.getConnectionInfo();
var mac = wInfo.getMacAddress();
NOTE1 : as mentioned in above java solution link you should add this permision <uses-permission android:name="android.permission.ACCESS_WIFI_STATE"></uses-permission> to app/App_Resources/AndroidManifest
NOTE2 : the above solution was for android,for ios you should find the solution with objective_c and convert to javascript with help of nativescript documentation.
NOTE3:In android 6 you might need request permision
You can also use this method to create a plugin for nativescript.
I am working on a Xamarin Forms app and all is going well with the Windows Phone building and running. However when I try and run the Android version, it build OK and then fails and I get an exception when calling the ServiceLocator to resolve ViewModel in the ViewModelLocator.
Breaks on the line in the ViewModelLocator
return ServiceLocator.Current.GetInstance<MainViewModel>();
with
System.Reflection.TargetInvocationException
Source "mscorlib" string
StackTrace "at System.Reflection.MonoMethod.Invoke (object,System.Reflection.BindingFlags,System.Reflection.Bind…"
and hovering over the 'GetInstance' shows
Could not resolve type: global::Microsoft.Practices.ServiceLocation.ServiceLocator.Current.GetInstance<global::hms.BillSplitter.ViewModel.PCL.MainViewModel>
My ViewModel's only constructor looks like
public MainViewModel(INavigationService navigationService, ICountryTippingService countryTippingService, AppSettings appSettings)
{
_navigationService = navigationService;
_countryTippingService = countryTippingService;
ThisAppSettings = appSettings;
ThisBillDetail = new BillDetail();
ThisBillDetail.TotalOnBill = 0;
}
All dependencies are registered ahead of this in the ViewModelLocator e.g.
SimpleIoc.Default.Register(() => new HmsPublicCoreMobileServiceClient(HmsCommonSettingConstants.HmsPublicCoreServiceUrl, HmsCommonSettingConstants.HmsPublicCoreServiceAppKey));
var prefService = ServiceLocator.Current.GetInstance<IPreferenceService>();
SimpleIoc.Default.Register(() => (SettingsHelper.GetCurrentSettings(prefService)));
SimpleIoc.Default.Register<MainViewModel>();
and some platform specific ones in the MainActivity.cs (Android) and AppDelegate(iOS) e.g.
SimpleIoc.Default.Register(() => new PreferenceService(this));
What I don't get is that it work beautifully in Windows Phone? What is it about Android that's different? Has anyone used SimpleIoc in Xamarin 1.3+?
Should I use a factory to create he ViewModel?
Any help would be great and much appreciated. I am using all the latest versions for MVVMLight (5.1.0.1) and Xamarin (1.3.3).
I finally worked out what the problem was and it's pretty basic and nothing to do with MvvmLight and/or Xamarin Forms updates!
I made the mistake of Registering a concrete class in a factory and then attempted to GetInstance on an Interface. SimpleIoC was not able to reconcile it.
from the code above
SimpleIoc.Default.Register(() => (SettingsHelper.GetCurrentSettings(prefService)));
should have been
SimpleIoc.Default.Register<IPreferenceService>(() => (SettingsHelper.GetCurrentSettings(prefService)));
so that the line
var prefService = ServiceLocator.Current.GetInstance<IPreferenceService>();
would know what I was talking about.
Anyhow, if you get errors like this, you'll know what to look for!!
