An Activity is an application component that provides a screen with which users can interact in order to do something, such as dial the phone, take a photo, send an email, or view a map.
Each activity is given a window in which to draw its user interface. The window typically fills the screen, but may be smaller than the screen and float on top of other windows.
An application usually consists of multiple activities that are loosely bound to each other. Typically, one activity in an application is specified as the "main" activity, which is presented to the user when launching the application for the first time. Each activity can then start another activity in order to perform different actions.
Each time a new activity starts, the previous activity is stopped, but the system preserves the activity in a stack .
When a new activity starts, it is pushed onto the back stack and takes user focus.

Popups or dialogs are a common to prompt the user to take action. Android popups are called Dialogs. The base dialog class is extended by AlertDialog class, which is extended by more specific dialog classes:
DatePickerDialog
ProgressDialog
TimePickerDialog
In this tutorial we will create AlertDialogs using the AlertDialog.Builder helper class.
AlertDialogs are divided into the following components:
Title Area
Content Area
Buttons - Positive, negative and neutral
None of the components are mandatory, and for each components there is a default view. In this tutorial we will see 3 examples:
Single-Choice Dialog
Dialog with buttons
Custom Dialog

During this brown-bag session you will be taken through the example of real application which uses SWF.
GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

2. UI
Thread
• When
Android
app
is
launched
one
thread
is
created.
This
thread
is
called
Main
Thread
or
UI
Thread
• UI
Thread
is
responsible
for
dispatching
events
to
widgets
• Avoid
doing
0me
consuming
tasks
in
UI
Thread
since
it
leads
to
app
that
does
not
respond
quickly
3. TesAng
UI
Responsivess
public class ThreadExample extends Activity implements OnClickListener {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Button button = new Button(this);
button.setText("Do Time Consuming task!");
setContentView(button);
button.setOnClickListener(this);
}
@Override
public void onClick(View v) {
try {
for(int i=0; i<10; i++) {
System.out.println(i);
Thread.sleep(10000);
}
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
9. Why?
• Android
UI
Toolkit
is
not
thread
safe
• If
you
want
to
manipulate
UI,
you
must
do
it
inside
the
UI
thread
• How
do
you
do
it
then?
You
can
use
– Activity.runOnUiThread(Runnable)
– View.post(Runnable)
– View.postDelayed(Runnable, long)
– …
10. Activity.runOnUiThread(Runnable)
• The
given
acAon
(Runnable)
is
executed
immediately
if
current
thread
is
UI
thread
• If
current
thread
is
NOT
UI
thread,
the
acAon
(Runnable)
is
posted
to
event
queue
of
the
UI
Thread
11. Example
of
RunOnUiThread
public class ThreadExample extends Activity implements OnClickListener, Runnable {
...
@Override
public void onClick(View v) {
Thread t = new Thread(this);
t.start();
}
public void run() {
// lengthy operation
try {
Thread.sleep(2000);
} catch (InterruptedException e) { }
runOnUiThread(new Update());
}
class Update implements Runnable {
// This action is posted to event queue
public void run() {
button.setText("Finished!");
}
}
}
13. Using
post
private int iteration;
...
@Override
public void run() {
try {
for(int i=0; i<10; i++) {
iteration = i;
button.post(new InfluenceUIThread());
Thread.sleep(1000);
}
} catch (InterruptedException e) {
e.printStackTrace();
}
}
class InfluenceUIThread implements Runnable {
public void run() {
button.setText("Iteration = " + iteration);
}
}
14. Using
Anonymous
Inner
Classes
@Override
public void onClick(View v) {
new Thread(new Runnable() {
public void run() {
try {
for(int i=0; i<10; i++) {
iteration = i;
button.post(new Runnable() {
public void run() {
button.setText("Iteration = " + iteration);
}
});
Thread.sleep(1000);
}
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}).start();
}
This
can
be
really
confusing...
15. AsyncTask
• Goal:
take

• Use
it
by
subclassing
it:
class
MyTask
extends
AsyncTask
• Override
onPreExecute(),
onPostExecute()
and
onProgressUpdate()
– Invokes
in
UI
Thread
• Override
doInBackground()
– Invokes
in
worker
thread
16. Example
(Google
SDK)
private class DownloadFilesTask extends AsyncTask<URL, Integer, Long> {
protected Long doInBackground(URL... urls) {
int count = urls.length;
long totalSize = 0;
for (int i = 0; i < count; i++) {
totalSize += Downloader.downloadFile(urls[i]);
publishProgress((int) ((i / (float) count) * 100));
}
return totalSize;
}
protected void onProgressUpdate(Integer... progress) {
setProgressPercent(progress[0]);
}
protected void onPostExecute(Long result) {
showDialog("Downloaded " + result + " bytes");
}
}
new DownloadFilesTask().execute(url1, url2, url3);
