How to prevent reloading of Activity or Fragment when rotating etc. on Android?

  • 772

I find that when you turn the device over or if the keyboard is hidden it Activityis reset again, going through onCreate()again.

A possible solution would be to use savedInstanceStatesaving a state variable, but it is not the best solution.

Is it possible to somehow prevent the `Activity from reloading on rotate, or other possible events that make it reset again?

java

    In your activity definition inside AndroidManifest.xmladd the property:

    android:configChanges="keyboardHidden|orientation|screenSize"

    for instance:

        <activity
        android:name=".myActivity"
        android:label="@string/app_name"            
        android:configChanges="keyboardHidden|orientation|screenSize"/>

    With this it does not reload the activity when performing a rotation, it does not execute the method againonCreate()
