will help you If the menu is always the same and you want to reuse it in more than one activity, you just define it like this:
code :
public class TestMenu {

    private final PopupMenu popupMenu;

    public TestMenu(final Activity activity, View anchor) {
        popupMenu = new PopupMenu(activity, anchor);
        popupMenu.getMenuInflater().inflate(R.menu.popup_menu, popupMenu.getMenu());

        popupMenu.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
            public boolean onMenuItemClick(MenuItem item) {
                switch (item.getItemId()) {
                    case R.id.one:
                        Intent vista = new Intent(activity, openCamera.class);
                return true;

    public void show() {
public class TestActivity extends Activity {

    protected void onCreate(@Nullable Bundle savedInstanceState) {

        Button menu_button = (Button) findViewById(R.id.menu_button);
        TestMenu myMenu = new TestMenu(this, menu_button);
        menu_button.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {

wish helps you I am trying to create a class that lets me call methods with a specified timout. I have the actual timeout implementation working, but am having trouble encapsulating this into a class successfully. , Your last suggestion would be the right way:
code :
public static Action<T> Timeout<T>(this Action<T> action, TimeSpan timeSpan);
public static Action<T1, T2> Timeout<T1, T2>(this Action<T1, T2> action, TimeSpan timeSpan);
public static Func<T, TResult> Timeout<T, TResult>(this Func<T, TResult> action, TimeSpan timeSpan);
public static Func<T1, T2, TResult> Timeout<T1, T2, TResult>(this Func<T1, T2, TResult> action, TimeSpan timeSpan);
/* snip the rest of the Action<...> and Func<...> overloads */
public static TDelegate Timeout<TDelegate>(this TDelegate d, Timespan timespan) where TDelegate : Delegate;

like below fixes the issue It appears that the sftp connection is closed when the variables go out of scope in __init__. Storing a reference to those in the class fixes the problem.
code :
def __init__(self, host, user='', pw='', log=''):
    """Initializes a connection to a remote log."""

    self.client = paramiko.SSHClient()
    self.client.connect(hostname=host, username=user, password=pw)
    self.sftp = self.client.open_sftp()
    self.log = self.sftp.open(log, mode='r', bufsize=1)
Creating a NSDateFormatter reusable class

Creating a NSDateFormatter reusable class

I hope this helps . In my app a JSON date string gets parsed different times (in my view controller, detailed view controller and in a share this page action). I want to set up only one NSDateFormatter and reuse it whenever I have to. , Change this:
code :
NSString *formattedDate = [self formattedDate:[_singleRelease objectForKey:@"release_date"]];
NSString *formattedDate = [UpcomingRelease formattedDate:[_singleRelease objectForKey:@"release_date"]];
+ (NSString *) formattedDate:(NSString *)jsonDateString {
    static NSDateFormatter *jsonFormatter = nil;
    static NSDateFormatter *readableFormatter = nil;
    if (!jsonFormatter) {
        jsonFormatter = [[NSDateFormatter alloc] init];
        [jsonFormatter setDateFormat:@"yyyy-MM-dd'T'HH:mm:ss.SSS'Z'"];
        readableFormatter = [[NSDateFormatter alloc] init];
        [readableFormatter setDateFormat:@"MMMM dd"];
        // Note - this code will not deal with a user changing the Region Format on their device

    NSDate *readableDate = [jsonFormatter dateFromString:jsonDateString];

    return [readableFormatter stringFromDate:readableDate];

I hope this helps you . Both classes actually extend Application, so that is not the problem. The problem is the @ApplicationPath annotation. The class with this annotation is used asthe main configuration class.

Hope this helps This is called cooperative multiple inheritance in python and works just fine.
What you refer to as an "Addon" class, is generally called a "Mixin".
