Hi:

On diferent Iphones we have the message of Low Memory Warning and the device have a lot of memory yet. Is it normal? What can we do? 

Thanks, 

Oihana

How do you know there is lots of free memory?  This memory is the RAM not the storage.

Ok, thanks!





I understand that nothing can be done in this case, right?

Depends. If other apps are consuming too much memory then that is hard to control. If it is your app consuming too much then you need to try to improve your code. You should not retrieve lots of data or in many DataWindows, and don’t forget to destroy objects.

Hi Oihana,

I also had this message a while back, even though I expected too to have "a lot of memory" (at least this is what was displayed by eon_mobile_deviceex::of_getfreememory( )).
In particular, I had the warning before opening the camera app via eon_mobile_cameraex object.

The warning actually comes from iOS, which detects excessive memory consumption by AWS + YourApp.

Anyhow, to tell the truth, the warning disappeared after I did a full deployment (with PS build 2170 and later versions)
Best.

Hi Oihana;

   My latest STD framework for PB2019 MR2170 now tracks application performance, memory space and device usage. If you download the example "OrderEntry" demo APP, and run it on your mobile devices, you can use that to record the actual impact on each type of mobile device. The App, DWO and NVUO stats are logged and a performance file is generated as well. The performance file can then be graghed in the three DWO's  I supply in the framework.

   Hopefully, that might give you an idea of any issues it encounters that might be similar to yours. If not, then the source of the memory consumption could be your App. This could be a quick way of testing AWS as to whether its related to this execution shell.

FYI: http://chrispollach.blogspot.com/2020/04/std-web-service-framework-2020r1.html

Food for thought

Regards ... Chris

PS: The latest "Beta" version of the framework (and demo OrderEntry App) also available for download is for PB2019 R2 MR2328.
