How large is your icon file. You have very large images. The are much to big. You could start by changing them to some that are a lot smaller.

@gordonlu310

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…
