Updating Amazon country settings

Purchasing e-books from Amazon can be confusing if you have accounts in multiple countries. Apparently, there can be only one country active and it defines which Kindle store can be used to purchase e-books. Below is the link to the country settings where the country can be selected:

Adding a dropdown (spinner) to toolbar in Android app

Here is a very elegant and simple solution on how to add a Spinner (a dropdown) to a toolbar in an Android app.
Add a Spinner as menu item and set the action view class

<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:yourapp="http://schemas.android.com/apk/res-auto" >

  <item android:id="@+id/spinner"
    yourapp:showAsAction="ifRoom"
    yourapp:actionViewClass="android.widget.Spinner" />
</menu>

Then handle the contents in onCreateMenuItem, as usual.

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.menu_layout, menu);
    MenuItem item = menu.findItem(R.id.spinner);
    Spinner spinner = (Spinner) MenuItemCompat.getActionView(item);
    spinner.setAdapter(adapter); // set the adapter to provide layout of rows and content
    s.setOnItemSelectedListener(onItemSelectedListener); // set the listener, to perform actions based on item selection
}
