    <!--For Gmail Intent: Since Android 11 (API level 30), most user-installed apps are not visible by default.
    In your manifest, you must statically declare which apps you are going to get info about, as in the following:-->
    <queries>
        <package android:name="com.google.android.gm" />
    </queries>
