Android Question Error while trying to run Open method

[AndroidMadhu]

Hello,
I am encountering error while trying to call open method at Razorpay.
Below is my code

Sub Button1_Click
Dim jo As JavaObject
Dim key As String="rzp_test_xxxxxxxx"
jo.InitializeNewInstance("com.razorpay.Checkout", Null)
jo.RunMethodJO("setKeyID",Array(key))
Dim Map1,Map2 As Map
Map1.Initialize
Map2.Initialize
Dim JSONGenerator1 As JSONGenerator
Map2.put("email", "[email protected]")
Map2.put("contact", "9876543210")
JSONGenerator1.Initialize(Map2)
Dim JSONGenerator As JSONGenerator
Map1.put("name", "Lito")
Map1.put("description", "Fare")
Map1.put("currency", "INR")
Map1.put("amount", "100")
Map1.put("prefill", JSONGenerator1.ToString)
JSONGenerator.Initialize(Map1)
Log(JSONGenerator.ToString)
jo.RunMethodJO("open",Array(act,JSONGenerator))

End Sub

The below Error I am getting :

Error occurred on line: 86 (Main)

The below Open method from Android Studio I am trying to call. The open method is running fine at Android Studio:

public void startPayment() {
              /*
                  You need to pass current activity in order to let Razorpay create CheckoutActivity
                */
              final Activity activity = this;

              final Checkout co = new Checkout();
              co.setKeyID("rzp_test_xxxxxxxxxx");

              try {
                      JSONObject options = new JSONObject();
                      options.put("name", "Lito");
                      options.put("description", "Fare");                     
                      options.put("currency", "INR");
                      options.put("amount", "100");

                      JSONObject preFill = new JSONObject();
                      preFill.put("email", "[email protected]");
                      preFill.put("contact", "9876543210");

                      options.put("prefill", preFill);

                      co.open(activity, options);
              } catch (Exception e) {
                      Toast.makeText(activity, "Error in payment: " + e.getMessage(), Toast.LENGTH_SHORT)
                                      .show();
                      e.printStackTrace();
              }
      }

Please advice.

Thanks

see this post

Method not matched

what is wrong when trying to use a jar created with eclipse ? package test1; import javax.swing.*; public final class testclass1 { public static void ShowEclipseLibDialog(String[] arg) { String st="Welcome to eclipse"; JOptionPane.showMessageDialog(null,st); } } //this was exported to jar...

The reason will probably be that you are passing the B4X JSONGenerator object to the underlying Java method and not a java JSONObject type.

 

[agraham]

jo.RunMethodJO("open",Array(act,JSONGenerator))

This passes a String array, it needs an Object array

jo.RunMethodJO("open",Array As Object(act,JSONGenerator))

 

[Erel]

Array = Array As Object.

 

[AndroidMadhu]

jo.RunMethodJO("open",Array As Object(act,JSONGenerator))

@Erel .. I am getting the same error as below :

That error means that JavaObject cannot find a method that matches the name and type of the parameters provided. As Andrew Digitwell points out above a B4X JSONGenerator objetc is not a Java JSONObject type. Although JSONGenerator does internally use a JSONObject it is a private internal field called 'json' and is not exposed. If you know what you are doing you could get at it with a Reflection library object otherwise you would need to instatiate and populate a JSONObject with inline Java or using a JavaObject - none of which I feel up to doing at the moment I'm afraid ?
