Android - Error while trying to add app shortcuts

Question

My app has minSdk = 21 and targetSdk = 26

I wanted to set up the app shortcuts

I've added the <meta-data> tag to the first activity that's launched when the app starts.

<activity android:name=".SignInActivity"
            android:theme="@style/SubscriptionsTheme.NoActionBar">
            <intent-filter>
                <category android:name="android.intent.category.LAUNCHER" />
                <action android:name="android.intent.action.MAIN"/>
            </intent-filter>
            <meta-data android:name="android.app.shortcuts" android:resource="@xml/shortcuts"/>
        </activity>

Then I created the xml-v25 directory and within it this shortcuts.xml file:

<shortcuts xmlns:android="http://schemas.android.com/apk/res/android" >
    <shortcut
        android:shortcutId="test"
        android:icon="@drawable/plus"
        android:shortcutShortLabel="test"
        android:shortcutLongLabel="long test" >

        <intent
            android:action="android.intent.action.VIEW"
            android:targetPackage="com.xxxxx.xxxxx.xxxxx"
            android:targetClass="com.xxxxx.xxxxx.xxxxxx.main" />

    </shortcut>
</shortcuts> 

when I try to build the app I get the following errors:

Error:error: 'long test' is incompatible with attribute android:shortcutLongLabel (attr) reference. Error:error: 'test' is incompatible with attribute android:shortcutShortLabel (attr) reference. Error:'long test' is incompatible with attribute android:shortcutLongLabel (attr) reference.

Hope this helps.

strings.xml

 <string name="long_shortcut">long test</string>
  <string name="short_shortcut">test</string>

Use reference of this strings in Manifest.xml

<shortcut
        android:shortcutId="test"
        android:icon="@drawable/plus"
        android:shortcutShortLabel="@string/short_shortcut"
        android:shortcutLongLabel="@string/long_shortcut" >

In java you can also assign this by using setLongLabel (CharSequence longLabel) and setShortLabel(CharSequence) of ShortcutInfo.Builder.
