再次安装后图标出现问题 Android Studio

Question

Some days ago I change my hard disk, so I need to re-install Android Studio. When I clone my project again some icons don't work (others are shown well). Icons are in right folder (when I have mouse hover the icon's name i can see them) and they are equal (64x64 PNG) .

Some previews of the icons appear, other not. So I can't start app because the icons that don't appear are null. I don't know what happened when I install again Android Studio, because app works fine before it. I tried to add another icon but it also doesn't appear, I tried to create another project and use the same icon but don't work and I tried to invalidate cache and nothing.

Answer 1

You should check on an android phone if you can download and play the app. If the problem is only with the emulator - it does get buggy, so the regular reinstalling the emulator/android studios, restarting your computer, trying to install a different emulator might work.

Otherwise:

The relevant line to look at is:

android:icon="@mipmap/ic_launcher" This means that the app is going to the 'mipmap' folder inside your directory, and looking for a file named 'ic_launcher' - to display it as the App icon.

You need to make sure this file name exists in the proper folder, and is in the correct format(this guide might help )

How to find the image location folder

If this doesn't help: remember that icons can be displayed at different qualities for different devices (hdpi, mdpi, xhdpi....) so sometimes if you want to make your own icon you need to make sure it fits the requirements (in the above guide)

Answer 2

Have you tried to check if all icons are in the project folder?
