Answer 1

It’s really simple! Just put:

android:configChanges="keyboardHidden|orientation"

in the AndroidManifest.xml file inside activity tag in which you require such functionality.

Example:

<activity
    android:name=".MyActivity"
    android:configChanges="keyboardHidden|orientation"
    android:label="Test"
    android:windowSoftInputMode="stateHidden" >
</activity>
