I use react-native to develop an app, and I need to connect to braintree (paypal value). The official provides 3 kinds of sdk, js, android, and ios. I try to connect to the native android library, but it doesn't seem to have any effect.After calling the native method in ReactNative, only "react-native-test" is output (No error is reported, and there is no change on the interface. It seems that it should jump to PayPal authorization to be normal). I'm not sure if it's my problem . I also tried to use js library in react-native, but after importing a certain method, my program doesn't start. Or can I only do it in webView? Has anyone connected with PayPal value? Can you give me some advice? Thanks.
Here is the documentation I refer to.
Below is my android codeļ¼
public class BraintreeValueModule extends ReactContextBaseJavaModule implements PayPalListener {
private static ReactApplicationContext reactContext;
private Callback successCallback;
private Callback errorCallback;
private BraintreeClient braintreeClient;
private PayPalClient payPalClient;
public BraintreeValueModule(ReactApplicationContext context) {
super(context);
reactContext = context;
}
#NonNull
#Override
public String getName() {
return "BraintreeValueModule";
}
#ReactMethod
public void test(){
System.out.println("react-native-test");
braintreeClient = new BraintreeClient(reactContext.getApplicationContext(), "sandbox_ykbznr4s_ctmssyj6wz2qcj2g");
FragmentActivity activity = (FragmentActivity) getCurrentActivity();
activity.runOnUiThread(new MyRunnable(activity,braintreeClient));
//The following writing method will report an error: Method addObserver must be called on the main thread
//if(activity != null){
// payPalClient = new PayPalClient(activity, braintreeClient);
// payPalClient.setListener(this);
//}
}
#Override
public void onPayPalSuccess(#NonNull PayPalAccountNonce payPalAccountNonce) {
successCallback.invoke(payPalAccountNonce.toString());
}
#Override
public void onPayPalFailure(#NonNull Exception error) {
if (error instanceof UserCanceledException) {
// user canceled
errorCallback.invoke("use canceled");
} else {
// handle error
errorCallback.invoke("error");
}
}
}
public class MyRunnable implements Runnable, PayPalListener {
private BraintreeClient braintreeClient;
private PayPalClient payPalClient;
private FragmentActivity activity;
MyRunnable(FragmentActivity activity,BraintreeClient braintreeClient){
this.activity = activity;
this.braintreeClient = braintreeClient;
}
#Override
public void run() {
if(activity != null){
payPalClient = new PayPalClient(activity, braintreeClient);
payPalClient.setListener(this);
}
}
#Override
public void onPayPalSuccess(#NonNull PayPalAccountNonce payPalAccountNonce) {
System.out.println(payPalAccountNonce.getString());
}
#Override
public void onPayPalFailure(#NonNull Exception error) {
if (error instanceof UserCanceledException) {
// user canceled
System.out.println("use canceled");
} else {
// handle error
System.out.println("error");
}
}
}
I believe you might have missed out the following few lines:
PayPalVaultRequest request = new PayPalVaultRequest();
request.setBillingAgreementDescription("Your agreement description");
payPalClient.tokenizePayPalAccount(getCurrentActivity(), request);
However, I believe it might still not work as I had similar problem when I was trying to integrate the drop-in.
I'm afraid that you'll need to initialise your clients (in your case, BraintreeClient and PaypalClient) in the onCreate method of your MainActivity.
And then try to call a reference to the client (either by SharedPreference or static variable) in your module to launch the drop in.
Pretty sure it's similar issue to your case.
This only applies to the v4 library.

I have a Blazor app built on .NET Core 3.1 and I need to be able to access USB port resources. I keep getting the error:
JavaScript interop calls cannot be issued at this time. This is
because the component is being statically rendererd. When prerendering
is enabled, JavaScript interop calls can only be performed during the
OnAfterRenderAsync lifecycle method.
I have a pretty simple Blazor component wrapping the Blazor.Extensions.WebUSB library
public partial class Recordings : ComponentBase
{
[Inject] private IUSB _usb { get; set; }
[Inject] private ILogger<Recordings> _logger { get; set; }
[Inject] private IJSRuntime _runtime { get; set; }
private bool _initialized = false;
protected override Task OnAfterRenderAsync(bool firstRender)
{
if (!_initialized)
{
this._usb.OnConnect += OnConnect;
this._usb.OnDisconnect += OnDisconnect;
this._usb.Initialize();
this._initialized = true;
}
return Task.CompletedTask;
}
protected async Task GetDevices()
{
var devices = await this._usb.GetDevices();
if (devices != null && devices.Length > 0)
{
_logger.LogInformation("Device list received");
}
}
private void OnConnect(USBDevice device)
{
this._logger.LogInformation("Device connected");
}
private void OnDisconnect(USBDevice device)
{
this._logger.LogInformation("Device disconnected");
}
}
And even though I'm doing the JS interop in the OnAfterRenderAsync as suggested I still get the same error. I've tried delaying the call to _usb.Initialize until a button is pressed (meaning the component should definitely have finished rendering.
I've tried disabling prerendering by setting the render-mode attribute in _Host.cshtml to Server instead of ServerPrerendered but nothing changed.
Your code should be like this:
protected override Task OnAfterRenderAsync(bool firstRender)
{
if (firstRender)
{
this._usb.OnConnect += OnConnect;
this._usb.OnDisconnect += OnDisconnect;
this._usb.Initialize();
this._initialized = true;
}
return Task.CompletedTask;
}
Note: When the firstRender variable is true, which occurs only once, you can use JSInterop. Before that you can't. This is the right time and place to initialize your JavaScript objects.
The OnAfterRender(Boolean) and OnAfterRenderAsync(Boolean) lifecycle methods are useful for performing interop, or interacting with values recieved from #ref. Use the firstRender parameter to ensure that initialization work is only performed once.
Hope this helps...
I am having one Application based on XamarinForms.
One background service I have created in Android project and that service would like to send data to ContentPage(which is in PCL) which is displayed to user.
How could I pass data to ContentPage(From xx.Droid project to PCL)?
One solution is:
To Create class in PCL with static variable(e.g. var TEMP_VAR), which will be accessed from xxx.Droid project.
Update value of that static variable(TEMP_VAR) from the service class from the xxx.Droid project.
Need to create Notifier on that static variable(TEMP_VAR)
Update the content page using MessageCenter Mechanism if require.
If there is any better solution, could you please provide me?
This can be achieved using the concept of C#
Dependency service
Event
Need to have 4 classes for such an implementation:
Interface in PCL(e.g. CurrentLocationService.cs) with event handlers defined in it.
namespace NAMESPACE
{
public interface CurrentLocationService
{
void start();
event EventHandler<PositionEventArgs> positionChanged;
}
}
Implementation of interface of PCL in xxx.Droid project (e.g. CurrentLocationService_Android.cs) using Dependency service
class CurrentLocationService_Android : CurrentLocationService
{
public static CurrentLocationService_Android mySelf;
public event EventHandler<PositionEventArgs> positionChanged;
public void start()
{
mySelf = this;
Forms.Context.StartService(new Intent(Forms.Context, typeof(MyService)));
}
public void receivedNewPosition(CustomPosition pos)
{
positionChanged(this, new PositionEventArgs(pos));
}
}
ContentPage in PCL - which will have object of implementation of interface.
Object can be obtained by
public CurrentLocationService LocationService
{
get
{
if(currentLocationService == null)
{
currentLocationService = DependencyService.Get<CurrentLocationService>();
currentLocationService.positionChanged += OnPositionChange;
}
return currentLocationService;
}
}
private void OnPositionChange(object sender, PositionEventArgs e)
{
Debug.WriteLine("Got the update in ContentPage from service ");
}
Background service in xxx.Droid project. This service will have reference of implementation of dependency service CurrentLocationService.cs
[Service]
public class MyService : Service
{
public string TAG = "MyService";
public override IBinder OnBind(Intent intent)
{
throw new NotImplementedException();
}
public override StartCommandResult OnStartCommand(Android.Content.Intent intent, StartCommandFlags flags, int startId)
{
Log.Debug(TAG, TAG + " started");
doWork();
return StartCommandResult.Sticky;
}
public void doWork()
{
var t = new Thread(
() =>
{
Log.Debug(TAG, "Doing work");
Thread.Sleep(10000);
Log.Debug(TAG, "Work completed");
if(CurrentLocationService_Android.mySelf != null)
{
CustomPosition pos = new CustomPosition();
pos.update = "Finally value is updated";
CurrentLocationService_Android.mySelf.receivedNewPosition(pos);
}
StopSelf();
});
t.Start();
}
}
Note : PositionEventArgs class need to be created as per usage to pass on data between service and ContentPage.
This works for me like charm.
Hope so this would be helpful to you.
I'm trying to use my first Action within a controller method with Play (2.1.x) but I get an InstantiationException error that don't really helps me understanding the problem.
Here is my method declaration inside my main controller :
public class Api extends Controller {
public class CORSAction extends Action.Simple {
public Result call(Http.Context ctx) throws Throwable {
Logger.info("Calling CORSAction for " + ctx);
Result result = this.delegate.call(ctx);
Http.Response response = ctx.response();
response.setHeader("Access-Control-Allow-Origin", "*");
return result;
}
}
#With(CORSAction.class)
#Transactional
public static Result login() {
// .... some code
return ok(Json.toJson(response));
}
}
Where did I made a mistake ?
I use IntelliJ Ultimate Edition for coding.
Thanks
Found by myself, the Action Class MUST be declared in a separated file otherwise it generates an InstantiationException.
I've been trying for ages to figure this our. when i try to bind my class with an interceptor i'm getting the following exception on the line
Kernel.Bind<MyClass>().ToSelf().Intercept().With<ILoggerAspect>();
Error loading Ninject component IAdviceFactory. No such component has been registered in the kernel's component container
I've tried with and without LoadExtensions, With about with using a Module to set up my bindings and my last attempt looks like this
internal class AppConfiguration
{
internal AppConfiguration( )
{
var settings = new NinjectSettings() { LoadExtensions = false };
Kernel = new StandardKernel(settings);
Load();
}
internal StandardKernel Kernel { get; set; }
public static AppConfiguration Instance
{
get { return _instance ?? (_instance = new AppConfiguration()); }
}
private static AppConfiguration _instance;
private void Load()
{
Kernel.Bind<ILoggerAspect>().To<Log4NetAspect>().InSingletonScope();
Kernel.Bind<MyClass>().ToSelf().Intercept().With<ILoggerAspect>();
}
internal static StandardKernel Resolver()
{
return Instance.Kernel;
}
}
My Logger Attribute looks like this
public class LogAttribute : InterceptAttribute
{
public override IInterceptor CreateInterceptor(IProxyRequest request)
{
return request.Context.Kernel.Get<ILoggerAspect>();
}
}
And my interceptor like this
public class Log4NetAspect : SimpleInterceptor, ILoggerAspect
{
protected override void BeforeInvoke(IInvocation invocation)
{
Debug.WriteLine("Running " + invocation.ReturnValue);
base.BeforeInvoke(invocation);
}
public new void Intercept(IInvocation invocation)
{
try
{
base.Intercept(invocation);
}
catch (Exception e)
{
Debug.WriteLine("Exception: " + e.Message);
}
}
protected override void AfterInvoke(IInvocation invocation)
{
Debug.WriteLine("After Method");
base.AfterInvoke(invocation);
}
}
Most likely you didn't deploy Ninject.Extensions.Interception.DynamicProxy or Ninject.Extensions.Interception.Linfu alongside your application [and Ninject.Extensions.Interception]. You have to pick exactly one of them.
With the code as you have it right now (LoadExtensions=false) it will fail to pick up the specific interception library - you should remove that and the normal extensions loading should wire the extension into the Kernel on creation for the interception bits to pick it up.
In addition to Remo Gloor's answer which pointed me toward adding the nuget package for Ninject.Extensions.Interception.DynamicProxy, I kept getting the same exception as the OP, until I manually loaded a DynamicProxyModule - the FuncModule is manually loaded as well, to work around a similar error involving the factory extension:
_kernel = new StandardKernel(
new NinjectSettings{LoadExtensions = true},
new FuncModule(),
new DynamicProxyModule()); // <~ this is what fixed it
I have a service proxy class that makes asyn call to service operation. I use a callback method to pass results back to my view model.
Doing functional testing of view model, I can mock service proxy to ensure methods are called on the proxy, but how can I ensure that callback method is called as well?
With RhinoMocks I can test that events are handled and event raise events on the mocked object, but how can I test callbacks?
ViewModel:
public class MyViewModel
{
public void GetDataAsync()
{
// Use DI framework to get the object
IMyServiceClient myServiceClient = IoC.Resolve<IMyServiceClient>();
myServiceClient.GetData(GetDataAsyncCallback);
}
private void GetDataAsyncCallback(Entity entity, ServiceError error)
{
// do something here...
}
}
ServiceProxy:
public class MyService : ClientBase<IMyService>, IMyServiceClient
{
// Constructor
public NertiAdminServiceClient(string endpointConfigurationName, string remoteAddress)
:
base(endpointConfigurationName, remoteAddress)
{
}
// IMyServiceClient member.
public void GetData(Action<Entity, ServiceError> callback)
{
Channel.BeginGetData(EndGetData, callback);
}
private void EndGetData(IAsyncResult result)
{
Action<Entity, ServiceError> callback =
result.AsyncState as Action<Entity, ServiceError>;
ServiceError error;
Entity results = Channel.EndGetData(out error, result);
if (callback != null)
callback(results, error);
}
}
Thanks
Played around with this a bit and I think I may have what you're looking for. First, I'll display the MSTest code I did to verify this:
[TestClass]
public class UnitTest3
{
private delegate void MakeCallbackDelegate(Action<Entity, ServiceError> callback);
[TestMethod]
public void CallbackIntoViewModel()
{
var service = MockRepository.GenerateStub<IMyServiceClient>();
var model = new MyViewModel(service);
service.Stub(s => s.GetData(null)).Do(
new MakeCallbackDelegate(c => model.GetDataCallback(new Entity(), new ServiceError())));
model.GetDataAsync(null);
}
}
public class MyViewModel
{
private readonly IMyServiceClient client;
public MyViewModel(IMyServiceClient client)
{
this.client = client;
}
public virtual void GetDataAsync(Action<Entity, ServiceError> callback)
{
this.client.GetData(callback);
}
internal void GetDataCallback(Entity entity, ServiceError serviceError)
{
}
}
public interface IMyServiceClient
{
void GetData(Action<Entity, ServiceError> callback);
}
public class Entity
{
}
public class ServiceError
{
}
You'll notice a few things:
I made your callback internal. You'll need to use the InternalsVisisbleTo() attribute so your ViewModel assembly exposes internals to your unit tests (I'm not crazy about this, but it happens in rare cases like this).
I use Rhino.Mocks "Do" to execute the callback whenever the GetData is called. It's not using the callback supplied, but this is really more of an integration test. I assume you've got a ViewModel unit test to make sure that the real callback passed in to GetData is executed at the appropriate time.
Obviously, you'll want to create mock/stub Entity and ServiceError objects instead of just new'ing up like I did.
