Can you try to pass the application context to the ContentObserver?

public class SettingsContentObserver extends ContentObserver {

    Context mContext;
    public SettingsContentObserver(Handler handler, Context context) {
        super(handler);
        this.mContext = context;
    }

    @Override
    public boolean deliverSelfNotifications() {
        return super.deliverSelfNotifications();
    }

    @Override
    public void onChange(boolean selfChange) {
        super.onChange(selfChange);

        //Profile1Activity.profile1(context);

        Intent i = new Intent("settingschanged");
        mContext.sendBroadcast(i);
    }
}
