Disabling Multi-window feature for Android N not working for an activity

问题

I want to disable multi-window support for an activity in my app. I have set resizeableActivity to false in my Manifest but when I long press recent app icon, the app still goes in multi-window mode. Below is my manifest:

<activity
    android:name=".MainActivity"
    android:resizeableActivity="false"
    android:excludeFromRecents="true"
    android:icon="@drawable/ic_launcher_home"
    android:theme="@style/AppThemeV3.CustomToolbar">
</activity>

Per documentation:

android:resizeableActivity=["true" | "false"]

If the attribute is set to false, the activity does not support multi-window mode. If this value is false, and the user attempts to launch the activity in multi-window mode, the activity takes over the full screen.

I have also tried to set this attribute to false at application level in manifest but it still starts in multi-window mode. Any pointer on what I am doing wrong will be highly appreciated?

The activity that is at the root of the task controls the window size. Your choices are:

1. Trace back to all possible task root activities in your app and ensure they all also have android:resizeableActivity="false"

2. Force this activity into another task, via Intent flags when you start it or manifest settings

[UPDATE] set android:resizeableActivity="false" in application tag. This will work now.

I have meet this problem before, and I try many time find that your must add android:launchMode="singleTask" && android:resizeableActivity="false" at the same time.
