Answer 1

By the way, I added android:resizeableActivity="false" to Manifest and then I switched language with Locale some Activities didn't change language. I noticed some activities have different resources. When I remove resizebleActivity property in Manifest it works OK.

Answer 2

Note: While starting a Unresizable Activity You should also add Intent.FLAG_ACTIVITY_NEW_TASK flag to Intent.Otherwise it will inherit the properties from the root activity.

Add android:resizeableActivity="false" for your Activity in your Manifest file or you can also add this for your Application:

<activity android:name=".YourActivity"
android:label="@string/app_name"
android:resizeableActivity="false" />

Answer 3

In your manifest, you need:

android:resizeableActivity="false"

So in your manifest file, for each activity that you want to disable the feature in, it would be like:

<activity android:name=".SomeActivity"
    android:label="@string/app_name"
    android:resizeableActivity="false" />

Or, if you want to disable it in your entire app:

<application 
   android:resizeableActivity="false" >
    . . .
</application>

As for what will happen, Android just won't let your app go into multi-screen mode - it will just stay full screen. See https://developer.android.com/preview/features/multi-window.html and https://developer.android.com/guide/topics/manifest/activity-element.html#resizeableActivity.
