I'm creating a pinned shortcut of my app launcher icon for Android O device (either emulator or physical device) and found strange behaviour. My code looks like this:

@TargetApi(Build.VERSION_CODES.O)

    private void createPinnedShortcut(Context context) {

        ShortcutManager shortcutManager = context.getSystemService(ShortcutManager.class);

        if (shortcutManager != null) {

            if (shortcutManager.isRequestPinShortcutSupported()) {

                Intent intent= MainActivity.getLaunchIntent(this);

                intent.setAction(Intent.ACTION_VIEW);



                ShortcutInfo shortcut = new ShortcutInfo.Builder(context, "my_shortcut_id")

                        .setShortLabel(context.getString(R.string.my_app_description))

                        .setLongLabel(context.getString(R.string.my_app_long_description))

                        .setIcon(Icon.createWithResource(context, R.mipmap.my_app_icon))

                        .setIntent(intent)

                        .build();

                shortcutManager.requestPinShortcut(shortcut, null);

            } else

                Toast.makeText(context, "Pinned shortcuts are not supported!", Toast.LENGTH_SHORT).show();

        }

    }

Everything works, but the launcher icon on the home screen is duplicated:

There is a normal icon, but on right lower corner it placed yet another copy of the icon (about 30-40% smaller).

My icon resources are in res/mipmap-*dpi* folders

Any hints, clues?

Update

Answering to comments:

1) AndroidManifest under ./build/manifests/debug looks like:

    <activity

        android:name="ru.ivanovpv.cellboxkeeper.android.MainActivity"

        android:exported="true"

        android:label="@string/cellboxkeeper"

        android:theme="@style/DefaultActivityTheme.Light"

        android:windowSoftInputMode="adjustResize" >

        <layout

            android:defaultHeight="800dp"

            android:defaultWidth="480dp"

            android:gravity="top|end"

            android:minHeight="320dp"

            android:minWidth="240dp" />



        <intent-filter>

            <action android:name="android.intent.action.MAIN" />



            <category android:name="android.intent.category.LAUNCHER" />

        </intent-filter> <!-- handle cbx files -->

        <intent-filter

            android:icon="@mipmap/cellboxkeeper"

            android:label="@string/cellboxkeeper"

            android:logo="@mipmap/cellboxkeeper" >

            <action android:name="android.intent.action.VIEW" />



            <category android:name="android.intent.category.DEFAULT" />

            <category android:name="android.intent.category.BROWSABLE" />



            <data

                android:host="*"

                android:mimeType="*/*"

                android:pathPattern=".*\.cbx"

                android:scheme="content" />

        </intent-filter> 

        <!-- receive files from android share intent -->

        <intent-filter

            android:icon="@mipmap/cellboxkeeper"

            android:label="@string/addToCellboxKeeper" >

            <action android:name="android.intent.action.SEND" />

            <action android:name="android.intent.action.SEND_MULTIPLE" />

            <data android:mimeType="*/*" />

            <category android:name="android.intent.category.DEFAULT" />

        </intent-filter>

    </activity>

2) There's not any folder like: mipmap-*-v26. Here's screenshot of folders in real apk. All icons in folders are normal (w/o duplication).

Any other versions?

I found solution, key is attribute android:logo:

<intent-filter

        android:icon="@mipmap/cellboxkeeper"

        android:label="@string/cellboxkeeper"

        android:logo="@mipmap/cellboxkeeper" >

        <action android:name="android.intent.action.VIEW" />

Deleting line with android:logo fixes duplication issue.

Hope, someone and sometimes will use and understands what's goin on
