Android Question help with library jar and java inline

[kkkpe]

Erel Help me

To do a test with an external library .jar I wrote a class:

package com.example;
public class MyClass {
private String nome;

public void setNome(String nome) {
this.nome = nome;
}

public String getNome() {
return nome;
}
}

with Android Studio As Padre.jar

B4A:
#AdditionalJar: padre
Sub Activity_Create(FirstTime As Boolean)
Dim d As String
jo.InitializeStatic("com.example.MyClass")
d=jo.RunMethod("setNome",Array("test"))
End Sub

but when I fill out my returns this error:
Installing file.
** Activity (main) Pause, UserClosed = false **

Don't use InitializeStatic. Initialize an instance of the class MyClass using

jo.InitializeNewInstance("com.example.MyClass", Null)

ok thanks, now works

Also, it should be pointed out that your Java method "setNome" returns void but in your B4A JavaObject usage, you're assigning its return value to a String.
