Out of Memory Error

[Tim]

I received this one today, while testing my app via livesync. I have seen it a couple of times over the last month or so:

"Out of Memory Error"  along with "No Stack available" message. 

I am developing in Platform using an in-browser client and livesync testing on Android and iOS tablets.

Our app uses a lot of images, but I still don't expect this to occur. Is there any way to increase heap/stack allocation for NativeScript apps built using Platform?

 

Cheers

Tim

Hi Tim,

The reasons behind "Out of memory" error can be different so in order to reproduce it the best way is to have a sample project which is throwing that error. Of course, I understand that sometimes sending projects is not an option (due to privacy or other reasons) so another way to provide us with more information is to log this error.
There are several approaches.
1.) Use the application events and specifically the lowMemoryEvent

in your app.js

var application = require("application");

application.on(application.lowMemoryEvent, function (args) {

    if (args.android) {

        // For Android applications, args.android is an android activity class.

        console.log("Activity: " + args.android);

    } else if (args.ios) {

        // For iOS applications, args.ios is UIApplication.

        console.log("UIApplication: " + args.ios);

    }

});

This way you can log additional information about what is causing the memory leak.
