Android Tutorial Adaptive Icons

Updated instructions are available here: https://www.b4x.com/android/forum/threads/adaptive-icons-simple-instructions-and-tips.123843/

Starting from Android 8 apps should include an adaptive icon. Without it the icon will appear as a small icon inside the larger template:

(B4A designer still uses an older targetSdkVersion so it is not affected.)

Adaptive icons are explained here:
The steps required are:

1. Create a folder under Objects\res named mipmap. It should include three files:

The two adaptive icon layers and a file named ic_launcher.png with the old icon. The old icon will be used on Android 7- devices.

2. Make sure that all three files are read-only. Otherwise they will be deleted during compilation.

3. Add to the manifest editor:

SetApplicationAttribute(android:icon, "@mipmap/ic_launcher")
CreateResource(mipmap-anydpi-v26, ic_launcher.xml,
<adaptive-icon xmlns:android="http://schemas.android.com/apk/res/android">
    <background android:drawable="@mipmap/background"/>
    <foreground android:drawable="@mipmap/foreground"/>
</adaptive-icon>
)

4. Delete this line from the manifest editor:

SetApplicationAttribute(android:icon, "@drawable/icon") 'delete

I do not know about you guys, but this is really one more annoying thing to worry about courtesy Google again. 'If it ain't broke , don't fix it' does not apply to Google.

This is not really the place to argue about the reasoning behind this feature, however it is explained here: https://medium.com/google-design/understanding-android-adaptive-icons-cee8a9de93e2

Not working for me

You are running it on which android Version (Device)?

1. Create a folder under Objects\res named mipmap. It should include three files:

The two adaptive icon layers and a file named ic_launcher.png with the old icon. The old icon will be used on Android 7- devices.

2. Make sure that all three files are read-only. Otherwise they will be deleted during compilation.

Are the files set to readonly? Means; check if they are still there (if not set to readonly they are removed at compilation).

You should also make sure that the referenced android.jar (Tools - Configure Paths) is from platform v27+.

Any idea on the recommended sizes in pixels for those three files? The YouTube clip talks about DP, not pixels.

Device is Pixel (8) and the files are read-only.

It was on android 25. I'll check with 27.

Still not working, it looks for the standard drawable:

java.lang.RuntimeException: Unable to start activity ComponentInfo{dudu.freecell/dudu.freecell.main}: android.content.res.Resources$NotFoundException: Drawable dudu.freecell:mipmap/ic_launcher with resource ID #0x7f030002

If I put back the deleted line from the manifest - it works but with the previous icon.

@derez please start a new thread for this in the questions forum. It is best if you upload a small project with only the icons.

 

[eps]

I couldn't get this working initially, but have now finally been able to set up an Adaptive icon. It was painful!

I had to remove lots of old android sdk installations which I wasn't referencing but somehow were playing havoc with this part of creating Android Apps. Everything else was working as expected and I had no other problems - just thought I'd share this info. with others just in case they were feeling it wasn't working but should. I used the example app to work out that it should perform as expected but wasn't doing so. Cheers

My lead Android development device a Samsung S9+ has just updated to the latest Oreo version. There was previously a dialogue accessible from Home Screen > Home Screen Settings > Change Icon Shape. It now appears to have been removed completely. I agree with others in saying this is a retrograde step.
