Razor Pay with Xamarin Forms - xamarin

I am trying to add Razor Pay to my Xamarin Form App, Though there is no direct way I created a binding Library from aar file.
as per Razor Pay document I added few line of code which is sufficient to work with test account but I am facing an Error which I am not sure how to solve it
Here is the Exception which is thrown
com.google.android.gms.tasks.OnSuccessListener.onSuccess(java.lang.Object)
here is my call stack
07-12 21:36:07.276 D/com.razorpay.checkout( 9046): java.lang.AbstractMethodError: abstract method
"void com.google.android.gms.tasks.OnSuccessListener.onSuccess(java.lang.Object)"

Here is my Code which i have implemented
public class MainActivity : global::Xamarin.Forms.Platform.Android.FormsAppCompatActivity, IPaymentResultWithDataListener, IOnSuccessListener, IOnFailureListener
{
public App app;
protected override void OnCreate(Bundle savedInstanceState)
{
TabLayoutResource = Resource.Layout.Tabbar;
ToolbarResource = Resource.Layout.Toolbar;
base.OnCreate(savedInstanceState);
Checkout.Preload(this);
Checkout checkOut = new Checkout();
checkOut.SetKeyID("MyAPIKEY");
Forms.SetFlags("IndicatorView_Experimental");
Xamarin.Essentials.Platform.Init(this, savedInstanceState);
global::Xamarin.Forms.Forms.Init(this, savedInstanceState);
CachedImageRenderer.Init(true);
Window.SetStatusBarColor(Android.Graphics.Color.Rgb(13, 141, 190));
app = new App();
LoadApplication(app);
if (IsPlayServiceAvailable() == false)
{
throw new System.Exception("This device does not have Google Play Services and cannot receive push notifications.");
}
CreateNotificationChannel();
LoginWithSocialIconViewModel.AuthenticateAction += OAuthGoogle;
Window.SetSoftInputMode(Android.Views.SoftInput.AdjustResize);
Activity activity = this;
JSONObject options = new JSONObject();
options.Put("description", "My Sample Payment activity");
options.Put("order_id", "order_EAMgUyLXrMfbmL");
options.Put("currency", "INR");
options.Put("amount", "100");
checkOut.Open(activity, options);
}
Can someone figure it out what m I missing

Just pasting this here so we can close the question.
You get this error java.lang.AbstractMethodError: abstract method "void com.google.android.gms.tasks.OnSuccessListener.onSuccess(java.lang.Object)" whenever your google play services packages is not compatible with the library you are trying to add.
So you would either have to change the version of your Google Play Services packages, or change the version of your AAR library file.

Flutter: Using path provider when app is in background

I am currently trying to implement FCM and local notifications into my Flutter app. I have successfully configured FCM and the Local notifications for normal notifications, But i also have a different type of notification that I would like to display with an Image, When my app is in the foreground the notification is displayed without error, However when I terminate the app / move it to background I get an exception when trying to save the image using path provider.
The exception:
MissingPluginException(No implementation found for method getApplicationDocumentsDirectory on channel plugins.flutter.io/path_provider)
I'm assuming this error is occurring because the path provider method channel is closed when the app is not in the foreground, Is there something I can do to fix this? Or if not the flutter_local_notifications plugin requires a filepath to a bitmap, Can I achieve saving the image and getting a path in a different way that will work in background (without path provider)?
(What I actually would like to display is an image from a link like this one: https://is1-ssl.mzstatic.com/image/thumb/WNUBiv2P6YSklHn9eA5nlg/1000x1000bb.jpeg)
Saving the image:
static Future<String> saveImage(Image image) {
final completer = Completer<String>();
image.image.resolve(ImageConfiguration()).addListener(ImageStreamListener((imageInfo,_) async {
final byteData = await imageInfo.image.toByteData(format: ImageByteFormat.png);
final pngBytes = byteData.buffer.asUint8List();
final fileName = pngBytes.hashCode;
final directory = await getApplicationDocumentsDirectory();
final filePath = '${directory.path}/$fileName';
final file = File(filePath);
await file.writeAsBytes(pngBytes);
completer.complete(filePath);
}));
return completer.future;
}
you need to register path provider in Application.java as well.
import io.flutter.plugins.pathprovider.PathProviderPlugin;
...
#Override
public void registerWith(PluginRegistry registry) {
PathProviderPlugin.registerWith(registry.registrarFor("io.flutter.plugins.pathprovider.PathProviderPlugin"));
}
Now that flutter uses Kotlin as the default language for android side, here is the Kotlin code:
override fun registerWith(registry: PluginRegistry) {
io.flutter.plugins.firebasemessaging.FirebaseMessagingPlugin.registerWith(registry?.registrarFor("io.flutter.plugins.firebasemessaging.FirebaseMessagingPlugin"));
PathProviderPlugin.registerWith(registry.registrarFor("io.flutter.plugins.pathprovider.PathProviderPlugin"))
}
This error occured because you did not registered flutter pluging in android MainAcitivity.
Your must change onCreate method of your MainActivity as below:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
GeneratedPluginRegistrant.registerWith(this.getFlutterEngine());
}

Xamarian - The name 'Resource' does not exist in the current context

I'm aware this question has been asked already - but none provided a resolution.
I have read these links:
Xamarin Forum, Stack Overflow Q and some others.
I have a relatively simple project at the moment and I keep getting the error "The name 'Resource' does not exist in the current context"
I can restart the project & it will work and "resource" is underlined in red and I can still debug the project.
Then after a few tries it goes and complains that it's not in the current context.
I did not make any changes to the project - I have come back to it now from a while ago.
So I'm going to guess that updates to VS 2015 have broken it.
My Code example:
using System;
using Android.App;
using Android.Content;
using Android.Runtime;
using Android.Views;
using Android.Widget;
using Android.OS;
using Android.Views.InputMethods;
using Android.Graphics.Drawables;
using Android.Graphics;
namespace Designer
{
[Activity(Label = "Designer", MainLauncher = true)]
public class MainActivity : Activity
{
// Global Varialble
Button butSignIn;
EditText tbxUsername;
TextView txtErrorMsg;
protected override void OnCreate(Bundle savedInstanceState)
{
base.OnCreate(savedInstanceState);
// Set our view from the "main" layout resource
SetContentView(Resource.Layout.Main);
butSignIn = FindViewById<Button>(Resource.Id.butSignIn);
butSignIn.Click += ButSignIn_Click;
tbxUsername = FindViewById<EditText>(Resource.Id.txtUsername);
txtErrorMsg = FindViewById<TextView>(Resource.Id.txtErrorMessage);
ActionBar.SetDisplayShowTitleEnabled(false);
ColorDrawable colorDrawable = new ColorDrawable(Color.ParseColor("#ff70bc1e"));
ActionBar.SetBackgroundDrawable(colorDrawable);
}
private void ButSignIn_Click(object sender, System.EventArgs e)
{
if (tbxUsername.Text == "Azmodan")
{
Intent intent = new Intent(this, typeof(MenuActivity));
this.StartActivity(intent);
this.Finish(); // this will close the activity and will close app if we try go back
}
else
{
txtErrorMsg.Visibility = ViewStates.Visible;
txtErrorMsg.Text = "inccorect login details, please try again";
}
}
}
}
Any help would be appreciated.

Xamarin.Forms App return data to calling App

So, either I am asking incorrectly, or it isn't possible, let's see which...
If my app (Xamarin.Forms) is launched from another app, in order to get a url from my app, how do I return that data to the calling app? I wrongly assumed SetResult and Finish, I also wrongly assumed StartActivityForResult, but there has to be a way to do this. I know how to get data INTO my app from another app, but not the same in return.
POSSIBLE PARTIAL SOLUTION -- UPDATE, FAILS
So I have to setup an interface in my PCL, and call the method from the listview item selected handler, in the Android app I can then do this:
Intent result = new Intent("com.example.RESULT_ACTION", Uri.parse("content://result_url"));
setResult(Activity.RESULT_OK, result);
finish();
(source: https://developer.android.com/training/basics/intents/filters.html)
Is this looking right, and how would I implement the same thing on iOS?
END
I deleted my previous question because I couldn't explain the problem clearly, so here goes.
I have a Xamarin Forms app, I want to use a section of this app as a gallery. Currently I have images displayed in a list, and I have an Intent filter set that launches this page when you select the app as the source for an image (such as upload image on Facebook).
My issue is that I don't know how to return the data (the selected image) back to the app / webpage that made the request. In android I understand that you would use StartActivityForResult and OnActivityResult to handle this, but I am using Xamarin Forms (Android, iOS, UWP) and can't really find a solution that could be used cross-platform.
Just a link to documentation that covers this would be great, but if you have an example then even better.
Thanks
EDIT
Here is the code used to launch the app, I am interested in getting data back from the Intent.ActionPick after the user has selected an image from a ListView, which is in a ContentPage in the PCL.
[Activity(Label = "", Icon = "#drawable/icon", Theme = "#style/DefaultTheme", MainLauncher = true, LaunchMode = LaunchMode.SingleTop,
ConfigurationChanges = ConfigChanges.ScreenSize | ConfigChanges.Orientation)]
[IntentFilter(new[] { Intent.ActionSend }, Categories = new[] { Intent.CategoryDefault }, DataMimeType = #"*/*")]
[IntentFilter(new[] { Intent.ActionView, Intent.ActionPick, Intent.ActionGetContent }, Categories = new[] { Intent.CategoryDefault, Intent.CategoryOpenable }, DataMimeType = #"*/*")]
public class MainActivity : FormsAppCompatActivity
{
protected override void OnCreate(Bundle bundle)
{
try
{
base.OnCreate(bundle);
CurrentPlatform.Init();
Xamarin.Forms.Forms.Init(this, bundle);
App _app = new App();
LoadApplication(_app);
if (Intent.Action == Intent.ActionSend)
{
var image = Intent.ClipData.GetItemAt(0);
var imageStream = ContentResolver.OpenInputStream(image.Uri);
var memOfImage = new System.IO.MemoryStream();
imageStream.CopyTo(memOfImage);
_app.UploadManager(memOfImage.ToArray()); //This allows me to upload images to my app
}
else if (Intent.Action == Intent.ActionPick)
{
_app.SelectManager(); //here is where I need help
}
else
{
_app.AuthManager(); //this is the default route
}
}
catch (Exception e)
{
}
}
It seems you cannot use remote URI to provide to calling app. Some posts I checked suggest to store the file locally and provide it's path to calling app. To avoid memory leak with many files stored I suggest to use the same file name then you will have only one file at any moment.
One more note. I tested this solution in facebook. Skype doesn't seem to accept that and, again, the posts I checked saying that Skype doesn't handle Intent properly (not sure what that means).
Now to solution. In main activity for example in OnCreate method add the follow.
ReturnImagePage is the name of my page class where I select an image
Xamarin.Forms.MessagingCenter.Subscribe<ReturnImagePage, string>(this, "imageUri", (sender, requestedUri) => {
Intent share = new Intent();
string uri = "file://" + requestedUri;
share.SetData(Android.Net.Uri.Parse(uri));
// OR
//Android.Net.Uri uri = Android.Net.Uri.Parse(requestedUri);
//Intent share = new Intent(Intent.ActionSend);
//share.PutExtra(Intent.ExtraStream, uri);
//share.SetType("image/*");
//share.AddFlags(ActivityFlags.GrantReadUriPermission);
SetResult(Result.Ok, share);
Finish();
});
Above will listen for the message when the image is selected.
Then in XFroms code when image is selected dowload it, store it, get path and send to Activity using it's path. Below is my test path
MessagingCenter.Send<ReturnImagePage, string>(this, "imageUri", "/storage/emulated/0/Android/data/ButtonRendererDemo.Droid/files/Pictures/temp/IMG_20170207_174559_21.jpg");
You can use static public class to save and access results like:
public static class StaticClass
{
public static int Result;
}

How to check internet connection continuously in Xamarin.Android Native?

My application is completely based on internet and it does not work without it, when the internet is not available or it is slow my application is getting stopped unfortunately.
I tried to implement try, catch but it is not helping me out as it is not throwing any exception, then I thought that I have to check the internet connectivity continuously till the app is running and stop any activity from performing and set a popup to connect to the internet.
I am able to get the popup whenever I call a method which has the following code inside it,
ConnectivityManager connectivityManager = (ConnectivityManager)GetSystemService(ConnectivityService);
NetworkInfo networkInfo = connectivityManager.ActiveNetworkInfo;
if (networkInfo == null)
{
AlertDialog.Builder alert = new AlertDialog.Builder(this);
alert.SetTitle("Network");
alert.SetMessage("Please turn of your Wifi or Mobile Data From Settings");
alert.SetPositiveButton("OK", (senderAlert, args) => {
Intent intent = new Intent(Android.Provider.Settings.ActionSettings);
StartActivity(intent);
});
alert.SetNegativeButton("Cancel", (senderAlert, args) => {
Toast.MakeText(this, "Cancelled!", ToastLength.Short).Show();
Finish();
});
Dialog dialog = alert.Create();
dialog.Show();
But I am unable to get the connection checked continuously, So Can some one Please help me to complete get this functionality in my application.
You need to use a BroadcastReceiver to monitor network changes.
[BroadcastReceiver(Enabled = true)]
[IntentFilter(new[] { "android.net.conn.CONNECTIVITY_CHANGE" })]
[Android.Runtime.Preserve(AllMembers = true)]
public class ConnectivityChangeBroadcastReceiver : BroadcastReceiver
{
public override void OnReceive(Context context, Intent intent)
{
if (intent.Action != ConnectivityManager.ConnectivityAction)
return;
//Check if is connected and raise a custom event or store
//the current in a static global variable
}
}
}
In Android 7.0, you need to remove IntentFilter from the class and register the receiver.
var receiver = new ConnectivityChangeBroadcastReceiver();
Application.Context.RegisterReceiver(receiver, new IntentFilter(ConnectivityManager.ConnectivityAction));
Another option is to use the ConnectivityPlugin https://github.com/jamesmontemagno/ConnectivityPlugin , which is easier to use.
CrossConnectivity.Current.ConnectivityChanged += HandleConnectivityChanged;
void HandleConnectivityChanged (object sender, ConnectivityChangedEventArgs e)
{
// You can check the network status in
//e.IsConnected
}
Note that The ACCESS_NETWORK_STATE and ACCESS_WIFI_STATE permissions are required.

Create a Share button on Windows Phone 8, 8.1 and 10 (Mobile)

How can I create a Share button (that share a defined mesage to another player contact) as the below image on Windows Phone 8, 8.1 and 10 (Mobile):
To create this script to share on Android Device I use the following code:
public class ShareScript : MonoBehaviour {
string subject = "Subject";
string body = "Body";
public void OnAndroidTextSharingClick()
{
StartCoroutine(ShareAndroidText());
}
IEnumerator ShareAndroidText()
{
yield return new WaitForEndOfFrame();
//execute the below lines if being run on a Android device
#if UNITY_ANDROID
//Reference of AndroidJavaClass class for intent
AndroidJavaClass intentClass = new AndroidJavaClass ("android.content.Intent");
//Reference of AndroidJavaObject class for intent
AndroidJavaObject intentObject = new AndroidJavaObject ("android.content.Intent");
//call setAction method of the Intent object created
intentObject.Call<AndroidJavaObject>("setAction", intentClass.GetStatic<string>("ACTION_SEND"));
//set the type of sharing that is happening
intentObject.Call<AndroidJavaObject>("setType", "text/plain");
//add data to be passed to the other activity i.e., the data to be sent
intentObject.Call<AndroidJavaObject>("putExtra", intentClass.GetStatic<string>("EXTRA_SUBJECT"), subject);
//intentObject.Call<AndroidJavaObject>("putExtra", intentClass.GetStatic<string>("EXTRA_TITLE"), "Text Sharing ");
intentObject.Call<AndroidJavaObject>("putExtra", intentClass.GetStatic<string>("EXTRA_TEXT"), body);
//get the current activity
AndroidJavaClass unity = new AndroidJavaClass ("com.unity3d.player.UnityPlayer");
AndroidJavaObject currentActivity = unity.GetStatic<AndroidJavaObject>("currentActivity");
//start the activity by sending the intent data
AndroidJavaObject jChooser = intentClass.CallStatic<AndroidJavaObject>("createChooser", intentObject, "Share Via");
currentActivity.Call("startActivity", jChooser);
#endif
}
}
Call DataTransferManager.ShowShareUI to show the sharing pane.
Handle the DataTransferManager.DataRequested event to provide the data when the user choses to share.
private void DataRequested(DataTransferManager sender, DataRequestedEventArgs e)
{
DataRequest request = e.Request;
request.Data.Properties.Title = "Share Text Example";
request.Data.Properties.Description = "An example of how to share text.";
request.Data.SetText("Hello World!");
}
See the Share data docs on MSDN for more info.
In Unity you can call these in an #if NETFX_CORE block so it runs only when using the Windows Runtime and not Mono. See Windows Store Apps: WinRT API in C# scripts. If you target Windows 10 then there are plug-ins at https://github.com/microsoft/unityplugins which include sharing. For earlier targets there are commercial plugins.
