Android app - crashes all the time

[Wojciech_Sz]

Hi!

My users are furious. The app crashes all the time on their Lenovo tablets.

I have an app with a lot of images. They were loading all at once. Support said that this is not okay. So I reduced the number of loaded images via security filters to 8k (info from the side menu)  max. And still the same!

What Can I do more? I thought that Lenovo devices were bad but on my private S20 Fe is still the same. Maybe not so often but it happens.

@Steve - please escalate. The customer is in a very bad mood!

You'll need to continue to work with Support. They can escalate to Development.

If the resolution of images is not really serious, try saving image with lower resolution (like 1200x900, 800x600, 640x480).

I suspect that the file size (related to very high resolution) may be one of the reasons causing the problem.

[Swoopy]

For your info, I've my apps containing over 40,000 rows of data, each of them has image. The apps run fine even on the 4 years old Android phones. My setting in 'UX > Options > Inputs > Image upload size' is 'Default'.

With this huge amount of rows, although the apps are not blasting fast but they do not crash.

Good point. 

But I use the XY with own background images which need to be in the full, high resolution. Also, available in offline mode.

Normal images could be in the lower resolution.

What's the XY image size in pixel and what file format used?

[Wojciech_Sz]

PNG. 5000x5000px

I'd say that's too high resolution, which I think 'might not' be necessary.

If the crash happens on the view having images with this resolution, try to reduce the pixel down to 2000x2000 pixels (or less) in JPG file format. You need to use the same image files for doing this and maintain their aspect ratio to keep XY shown at the same locations.

I'm using XY map as well. The JPG map image is 2000x1235 pixels, it's pretty enough and never produces problem.

[Wojciech_Sz]

I will try. BTW why JPG?

[Swoopy]

I think JPG format give you smaller file size (at the same resolution). Also you can trade off the file size with color quality. If I don't need anything benefit from PNG (like transparency), JPG is the best for me.
