Question

Android 8.0 adaptive icons support

Since releasing an Android build supporting api level 27 we notice our app icon is displayed smaller and in a white frame on Android 8+ devices, because of this:

Adaptive icons  |  Android Developers

We can probably work out how to add in the right resources to fix this, but naturally it would be more convenient if the SDK handled it, as well as for apps that don't use inhouse ANEs etc.

    To fix this problem we added adaptive icons manually. And adjusted the jenkins pipeline to resign app after changing content.

    It looks like that:

    cd $WORKSPACE/build/
    rm -rf $WORKSPACE/build/App-release
    apktool d App-release.apk
    sed -E 's/android:icon="@mipmap\/icon"/android:icon="@mipmap\/ic_launcher" android:roundIcon="@mipmap\/ic_launcher_round"/' App-release/AndroidManifest.xml > App-release/AndroidManifestModified.xml
    rm App-release/AndroidManifest.xml
    mv App-release/AndroidManifestModified.xml App-release/AndroidManifest.xml
    sed -E 's/<\/resources>/    <color name="ic_launcher_background">#ff005878<\/color>\'$'\n''<\/resources>/' App-release/res/values/colors.xml > App-release/res/values/colorsModified.xml
    rm App-release/res/values/colors.xml
    mv App-release/res/values/colorsModified.xml App-release/res/values/colors.xml
    cp -R ../manual_content/android_res/res/* App-release/res/
    apktool b App-release
    jarsigner -verbose -keystore ../cert/android_release.p12 -storetype pkcs12 -storepass PAS$WORD App-release/dist/App-release.apk "ALIAS NAME FOR KEY"
    jarsigner -verify App-release/dist/App-release.apk
    ../tools/android-sdk-macosx/build-tools/24.0.3/zipalign -v 4 App-release/dist/App-release.apk App-release/dist/App-release-resigned.apk
    rm App-release.apk
    cp App-release/dist/App-release-resigned.apk App-release.apk

    In res folder we store

    mipmap-anydpi-v26 with two xml files created from Android Studio Asset creator

    mipmap-hdpi with three files ic_launcher_foreground.png, ic_launcher_round.png, ic_launcher.png

    mipmap-mdpi with same files but different size

    and so on

    mipmap-xhdpi

    mipmap-xxhdpi

    mipmap-xxxhdpi

      someone in the starling forums is reporting an even easier way:

        For anyone who's wondering, this turns out to be not that hard - you can import your foreground and background in Android Studio, rename "ic_launcher" to "icon" wherever it appears as the default name,  and then include the files in the res/ folder it produces as android resources - if you're using ANEs, you can package the resources in one of them (if not I guess you can use aapt and resign the apk) and they'll show up in Android 8.

          Hi ,

          what do you mean by "import your foreground and background in Android Studio" ?

          instructions here:

          Create app icons with Image Asset Studio  |  Android Developers

          you can just create a fake Android Studio project and copy the directories/files it creates.
