Adaptive Icon not working

Question

manifest:

Answer 1

ic_launcher.xml should be like this

<?xml version="1.0" encoding="utf-8"?>
<adaptive-icon
    xmlns:android="http://schemas.android.com/apk/res/android">
    <background android:drawable="@color/white"/>
    <foreground android:drawable="@mipmap/ic_launcher_foreground"/>
</adaptive-icon>

Answer 2

I had issues getting my adaptive icon to display. Turns out I had done nothing wrong. It started working after I did a 'Clean Project' in Android Studio.

Answer 3

I too have faced the same issue, here is how I have fixed this issue

1. Right click on resource -> New -> ImageAsset

2. Choose the ic_launcher_background icon and ic_launcher_foreground as shown in below screen

3. Android studio creates an ic_launcher.xml under resource mipmap (anydpi-v26)

    <?xml version="1.0" encoding="utf-8"?>
   <adaptive-icon xmlns:android="http://schemas.android.com/apk/res/android">
       <background android:drawable="@mipmap/ic_launcher_background"/>
       <foreground android:drawable="@mipmap/ic_launcher_foreground"/>
   </adaptive-icon>
   

4. Now inside the Manifest.XML, declare the icon and round icon something shown in like below

   <application
   android:allowBackup="true"
   android:icon="@mipmap/ic_launcher"
   android:label="@string/app_name"
   android:roundIcon="@mipmap/ic_launcher"
   android:supportsRtl="true"
   android:theme="@style/AppTheme">
   
   
                   .......</application>
   

   Yes that's all and Run your app on any device it appears

Answer 4

Adaptive icon requied API 26 so you need to update your buildtools to at least 26.0.0 version

Answer 5

I tried to debug it using an <ImageView>. When I did so, I got a backtrace ending with:

Caused by: java.lang.IllegalArgumentException: Path string cannot be empty.

Turns out my ic_launcher_foreground.xml had some <path> elements with empty android:pathData attributes.

Deleting those empty <path>s made the icon work!
