Android Question Image Size /Resolution/format

[shashkiranr]

Hi All,

I have finally completed an app for a client. It basically displays around 300 to 400 images of products manufactured by my client. my client wants the app to be offline so i have to save all the images in the app itself. Google allows a maximum of 50 MB per application. I am saving all the images in db3(sqlite 3). I have a few question regarding the images.

1. What can be the optimum resolution of the image so that it can be shown in all the devices.(eg 300 X 300)

2. Currently it is in JPG. Should i convert all the images into PNG

3. Are you aware of any compression software which can compress bulk images at once.

Kindly let me know your suggestion and inputs regarding this. Will be awaiting for your responses.

Regards,
SK

1. There isn't any optimal resolution. You should make sure to use LoadBitmapSample to avoid loading large images.
2. If size is the most important factor then JPG compression (which is configurable) is better.

Hi Erel,

Thank you for your reply. The reason i asked the resolution is there are few images which are more than 800 X 1000 and has more size. so what can be the minimum approximate size needed so that the entire application does not exceed 50 MB. Without these images currently the size of the app is 2.5 MB.

You will need to test it. It is not possible to say.
