Cannot instanciate an array of native type

[stevielavern]

Hi,

How can I instanciate an array of native Java type, say "int" ?
The goal would be to be able to pass it to a method that will write to this array, something similar to this :

var intArray = /* ??? allocate java int array ??? */;
this.fillMethod.call(this, intArray, intArray.length);
send('data', intArray);

Thank you,

You mean a primitive array (int[])?

Use

var intArray = [1, 2, 3];
...

Update:
Could you use a Java method that returns an array?

var intArray = [1,2,3];
intArray = klass.staticFillMethod(intArray);
send('data', intArray);

No, in my case I cannot use a method that return an array, my method only fills the buffer passed as parameter.

As you suggested first, I tried to simply instantiate a JS array (var intArray = new Array(size); or var intArray = [1, 2, 3];) and pass it as is, but it is left untouched.

One possibilty would be to create a wrapper class in Java so you could load it with Java.openClassFile(...).load().

Java.openClassFile('classes.dex').load();
const helperClass = Java.use("....helperClass");

But I think the preferred way would be something like that (but it isn't currently implemented)

const intArray = Java.primitiveArray("int[]", [1,2,3]);
klass.fillMethod(intArray);

Ok, thanks a lot for your answer.
This is indeed not the preferable way, but could be a usable workaround.

I'll update my post later when I use it.
