Question

Is it possible to start an intent when the phone goes from portrait to landscape mode and vice versa?

Thanks!

Yes it is possible.

Add the following to the activity declaration in the manifest:

android:configChanges="orientation"

so it looks like

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

Write the code to whatever you want in onConfigurationChanged() method

@Override
public void onConfigurationChanged(Configuration newConfig) {
    //write your logic here
    System.out.println("...inside config change...");
    super.onConfigurationChanged(newConfig);
}
