Error when trying to compile app for new version of android required by google

[CristianoSiqueira]

Hello Everyone, when having to recompile my app for Android 12, otherwise I would lose my developer account, I come across the following error mentioned below. Note that in past recompilations everything went well. I didn't change anything in the app or make any changes
Thank you in advance for your help.

App Inventor is unable to compile this project.

Reduce the size of your icon

New app icon restrictions at build time?

A few new build errors have popped up on the board for icon types recently, for apps that previously built. Is this an iOS thing?

Taifun

[CristianoSiqueira]

any size suggestions?

Building OK here with a 512x512 jpg file.

and will it work? my width and height is on average 122x105

[Taifun]

@CristianoSiqueira

my width and height is on average 122x105

There only is one app icon
It should be a square format
What about trying a 512 x512 app icon?

Taifun

[CristianoSiqueira]

In this case, does this "generating icons" mentioned in your observation refer to the app icon? or the images of the endowments? Ex. Options... Games... etc

Publish App On Google Play Store

Here is my final statement on the → launcher icon for Android (as long as I don't get a contrary and convincing statement from the MIT team): I recommend using an icon with the dimension 192x192px (in my case 78 KB) and uploading this to the media section (assets). If I use a 512x512 icon (0.6 MB) or 1024x1024 (1.3 MB), the same ic_laucher.png files are created as in the case of the 192x192 icon. Note: But the original icon remains in the assets (1.3 MB in case of an icon with 1024x1024px and…

Thanks for the tip, after changing the icon from 300x300 to 512x512 the build option generated the apk without problems, I hope that with the SDK 33 version Google Development will accept it as the Android 12 version Thank you very much in advance

512x512

This is the size of the app icon for the Play Store:

App Inventor version nb181 release scheduled for December 19th

Because the app icon is used to generate all of the sizes, having a higher fidelity icon means sharper icons when they are downsampled (if we wanted to be pedantic, 576 is the LCM of the Android variants and would be a better choice than 512 when it comes to scaling). Eventually, for iOS we will also need to provide a 1024x1024 image in the app bundle for the App Store, so it made sense to pin the size to the needs of the various app store platforms (it needs 18 different variants). Note that a…

However, I couldn't see any differences when I uploaded a launcher icon with the size 192x192px or 512x512px to the assets. EDIT: And I would like to add that I can neither see differences nor determine differences/deviations analytically. So it doesn't seem to matter from which image size (192px or 512px) the corresponding launcher icons are generated.

[STEFANO_CHERUBINI]

the 512x512 what format should .png have?

[Anke]

@STEFANO_CHERUBINI

what format should .png have?

What do you mean by "format"?

As I have already explained often enough, for Android I would generally choose a launcher icon and a PNG image with a size of 192x192px.

(For my iOS apps I used 1024x1024px PNG icons.)

@Anke

I would generally choose a launcher icon and a PNG image with a size of 192x192px

Why? Because I want my app (APK/AAB) as small as possible. If I use a 512x512 or 1024x1024px launcher icon, this remains in the assets and is significantly larger than a 192x192px image.
