Again Out of memory with using LoadBitmapSample

[coslad]

Hi ,

I have a customlistview with only 15 items , each item have 3 label and 2 imageview , in some devices (not to all) when a load the CLV tha app crashs with OOM error.

To load the bitmap i use :

immagine1.Bitmap=LoadBitmapSample(folder,appoggio,90,90)

Now it is incredible this error, when the device have more the 400Mb of free ram .
Please help me .
Thanks

Your app cannot use 400MB.
Android restricts you to a lot lesser. There have been constant changes in the handling of bitmaps in the OS.
Last I remember depending on the version your heap size is 64 MB.
What OS are you testing on?
What is the size of your bitmaps?

Note that you should use 90dip instead of 90. 15 images with that size should not consume too much memory. What is the size of the other images?

The customlistview is not on the first activity but before to load the list i need to open 3 activity , and one of these have a sliding panel with many views .
The image i load is attached , his dimension doesn't care becouse LoadBitmapSample redim it .
The technical details of the device are :

- 5.3 inch QHD screen, 960*540 pixel display
- CPU: 1.2GHz MTK MT6589 quad-core, GPU: Power VR SGX544
- 1GB RAM + 4GB ROM

This problem doesn't came out if the app run on a old Galaxy S -

If i can trap the exception , i could not load the image on the device with low memory , otherwise i have to remove all the view before load that layout .

what do you think?

Which version of B4A are you using? Starting from v2.7 the bitmap should be downsampled automatically if there isn't enough memory.

The version is 2.71 see the attach , i have attached a video that show you what appen , please watch it .

Your process is out of memory. You should make sure that all bitmaps are loaded with LoadBitmapSample, the designer images are not larger than they need to be and that you are not loading unnecessary images.
