Android Question Problem with allocating lot of memory RAM

[Luiz Fernando Orlandini]

Hi All.

My APP implements an interface that calls a service to monitor latitude and longitude of ther user by GPS.

My service is implemented with a loop, using StartServiceAt, with a period of 5 seconds. For each 5 seconds the APP calls a web service to register the position of the user.

Well, everything works like a charm, except the consume of memory RAM. After some minutes (30 or 40), the application that has started with approximately 13 Mb, could increase until 90/100 Mb.

How can I identify what piece of code is responsible for this higher consume of memory RAM?

Thanks

Do you get an out of memory error? If not then it is possible that the garbage collector has not released the memory yet.

Yes Erel. I got an out of memory error.

During execution I could note the log message

Downsampling image due to lack of memory.

 

[Erel]

This means that you are loading large bitmaps and running out of memory. Make sure to use LoadBitmapSample when loading images.

 

[Luiz Fernando Orlandini]

Erel, I'm afraid that is not possible to use LoadBitmapSample.

All my layouts are composed by some panels that use a background images.

When I use the APP alternating with all layouts, after about 10 interactions approximately, the out of memory errors occurs.

Any ideia?

 

[Erel]

Not sure that I understand why you cannot use LoadBitmapSample. If the images are included in a layout file then you should make sure that the images are not too large. Otherwise you will run out of memory.

 

[Luiz Fernando Orlandini]

Well.

I have some panels defined in project time in my layouts. This panels use the background image definition.

Some example of image size that I have in my project.

Layout Available.bal
top-background-available - 480x98px - 4,70Kb
background-available - 480x662px - 70Kb
btn-menu - 81x74px - 3kb
btn-menu-pressed - 81x74px - 3kb

Layout NewOrder.bal
background-full - 480x760px - 11Kb
top-background-available - 480x98px - 4,70Kb
btn-back - 81x74px - 3kb
btn-back-pressed - 81x74px - 3kb
btn-accept - 240x102px - 2,96Kb
btn-accept-pressed - 240x102px - 2,96Kb
btn-reject - 240x102px - 2,96Kb
btn-accept-pressed - 240x102px - 2,96Kb

Can you post the code in Activity_Resume? Which line raises the error?
