Image Size (splash screen)

[TIMAI2]

@ChrisWard

larger screen sizes are around 3120 x 1440 pixels

That would be the native resolution of the device, not what AppInventor scales to, which would be the native resolution divided by the density. So, as a rough guide, say the density is 2.5 perhaps the biggest image needed (for phones) may be 1248x576...

For my phone, with a native resolution of 2400x1080 and a density of 2.625, image size could be 914x411

You should try to do much the same for any images you use, based upon the size of their containing components. Use thumbnails in listviews etc. where you might want to display the same large full image.

To avoid distortion of aspect ratio (most phones have an aspect ratio of @ 1 : 2.2) enjoy reading this:

Here also a reworked universal solution, which has dispensed with the clock and uses a webviewer instead (javascript to calculate the aspect ratio of the image). This should now fit any image, with the correct aspect ratio, centred on the screen, to the screen1 image background, as you will see, no cropping, and no extensions The html file should be in the same directory as the images used. greenCircleUniversalDemo.aia (79.2 KB) BLOCKS SCREENSHOTS
