How to put values in arrays in the watch storage?

Hi,

I would like to have values changed in a widget and stored in an array, even if the widget is closed in the watch storage and recall these values as soon as the widget is startet,

so that the user could continue.

Something like a counter that continues counting from the latest active value, when the widget was used.

How can I do this? Any constraints to consider?

A small example with guidance where to put what would be very helpful...

Thanks!

myArray=new [20] gives you an array that's 20 elements long, with each being element null

myArray=[20] give you an array that's 1 element long and it's value is 20.

myArray=[1,2,3,4,5], and array 5 elements long, with the values 1 to 5

so status=new[20] is an array with 20 elements, and each element is null.

if (status==null) (as you check in your code) it's not an array, so you can't do status[i]=0

if I change it to (status[0]==null) to identify at least the value of the first element, I still receive an error

Is there a possibility to give each element a predefined value right from the initialization (instead of each element being null)?

Add some println calls to see what you're dealing with.

Problem seems to be command line before:

status=Storage.getValue("status");

I try to get values from a store arry (which is not there yet in the first initialization, first storage onStop).

How can I solve this? How do it read in an array?

status will be null if the key doesn't exist, so you can do

if(status==null) {status=new[20];}

which will make status a 20 element array with each element being null.

Great it works! Thank you. I was wandering because I defined the array already outside the class by

var status = new [20];

so it should have already been there or?

When you do

status=Storage.getValue("status");

status is the result of that call, and not the type it was before, and if the key isn't found, that will be null.
