B4J Question Warning #22 message

Daestrum said:

Should I be concerned at this warning, I am passing an Integer to a sub that expects a javaobject.

I thought a javaobject could take any type of variable.

B4X:

...
Log(Integer_toHexString(1,99)  << warning on this line  "Types do not match. (warning #22)"
...

Because Java is nice - in that case it just uses the class ie Integer for the call as that what it expects to be there

In 'pure' Java you would write Integer.toHexString(99);

I would guess the generated java for the Sub would be like

B4X:

public String name_of_the_sub(Object o, Integer arg){
Class<?> c = o.getClass();
...
return c.toHexString(arg);
}
