New Features and Upgrades Coming To tvOS 14

In a recent Worldwide Developer Conference (WWDC), Apple revealed new features and minor upgrades coming to its much anticipated tvOS 14 update. Rolling out to all supported Apple TV 4K devices, the new update aims to bring a number of small incremental changes to enhance viewer experiences. Although tvOS 14 received a little mention in the WWDC, we are expecting more changes to be unveiled during the annual keynote this fall. 

Among the significant changes coming to tvOS 14 is the quick game resume, a feature similar to that on PS4 and Xbox One. It lets you resume a game on Apple TV where you left off. At the same time, it renders support for Xbox Elite series 2 and Xbox Adaptive Controllers. Let’s explore the upcoming features and other significant changes in tvOS 14.

New tvOS Features and Upgrades

As of now, Apple has only revealed limited information about its forthcoming tvOS 14 update. For all we know, this new Apple TV update mainly focuses on extending the existing functionalities rather than introducing new features. Based on the information shared by Apple during WWDC, below are the main features and upgrades coming to tvOS 14.  

Picture-in-Picture

Picture-in-Picture (PiP) was previously available in select iPad devices. With tvOS 14, Apple TV users will now gain access to this feature that allows them to move between apps while keeping the videos running. Having said that, the PiP feature was supported by select Apple TV 4K devices. However, it was previously limited to fewer applications and media types. Apple has extended their PiP feature with the latest update as it will now be supported by many other applications, in many other places. 

Multiple User Accounts

The previous version of tvOS (i.e tvOS 13) rendered multi-user support, providing different content recommendations for each user profile. However, the feature was limited to watching movies and TV shows. With the forthcoming release, Apple plans to extend this functionality for games as well via Apple Arcade.

Extended Gaming Support

As already mentioned above, tvOS 14 brings significant changes and upgrades for game lovers. Amongst the most sought after features is the quick game resume that enables users to resume a gaming app right where they left. In addition, it will now support Xbox Elite Series 2 and Xbox Adaptive Controllers that were released in late 2019. Besides, it will also provide game recommendations to users based on their previous gaming activities. 

Other Notable Changes

There are several other changes rolling out this major tvOS update. The list includes the following notable changes in tvOS:

• Users can now use AirPlay feature to mirror 4K content from an iPhone to the Apple TV 4K devices
• tvOS 14 enables audio sharing feature for all devices having H1 chip installed
• Users can stream 4K videos from YouTube once Google releases the app update
• HomeKit videos will now be accessible through Control Center
• Users can select aerial screensavers based on various themes

Picture in Picture

The Picture-in-Picture feature on the iPad is now extended to the iPhone with iOS 14.

Create P2P connections with WiFi Direct in android

What is Android Wi-Fi P2p APIs?

It allows nearby devices to connect and communicate among themselves without needing to connect to a network or hotspot.

Advantages over traditional Wi-Fi ad-hoc networking?

• Wifi-Direct supports WPA2(Wifi Protected Access) encryption.
• Android doesn't support Wi-Fi ad-hoc mode.

Let's implement : 

Set up application permissions :

Set up a broadcast receiver :

With the help of broadcast receiver we will be able to listen various phases of connections between 2 devices.

Constructor of broadcast receiver class : 

The onReceive() method of broadcast will look like this : 

Create an activity and register broadcast receiver : 

1- Create intent Filter : 

 

WifiP2pManager.WIFI_P2P_STATE_CHANGED_ACTION : Indicates a change in the Wi-Fi P2P status.

WifiP2pManager.WIFI_P2P_PEERS_CHANGED_ACTION : Indicates a change in the list of available peers.

WifiP2pManager.WIFI_P2P_CONNECTION_CHANGED_ACTION : Indicates the state of Wi-Fi P2P connectivity has changed.

WifiP2pManager.WIFI_P2P_THIS_DEVICE_CHANGED_ACTION : Indicates this device's details have changed.

2- Register receiver in OnCreate : 

Listen to broadcast receiver :

1- Now when you run the application you will find that your control will get to the WIFI_P2P_STATE_CHANGED_ACTION, so this the point where you will start finding the peers(nearby you) if your WIFI state is enabled.

So in your broadcast receiver check the wifi-state and start listen for peers if it is enabled.

And your startFindPeers method will look like this on Activity : 

2- As soon as you successfully discover the nearby peers the WIFI_P2P_PEERS_CHANGED_ACTION in your broadcast receiver class gets trigerred, so this is the point to get the list of all the available devices.

So, inside your broadcast onReceive method and add the following code in WIFI_P2P_PEERS_CHANGED_ACTION and register your peer callback : 

This requestPeer() method is implicitly provided by WifiP2pManager class but this peerListListener is custom and is used to as a callback for peerList : 

PeerListener will be like this : 

3- Now if the call is successful then you will get the list of all available devices with various other parameters in onPeersAvailable, iterate through the list and select one device to connect.

Now next step is to get the peer configurations of the selected item in the peerList and connect with peers using deviceAddress : 

   

4- Once we get the successfull connection with the peer the WIFI_P2P_CONNECTION_CHANGED_ACTION is trigerred and this is the point to get the connection info from the connectionListener callback.

 The connection info can be get by passing connection callback as a parameter in requestConnectionInfo() method.

And the connectionInfoListener will look like this :

Great our peers are now connected to each other and can transfer data between themselves.

5- To transfer the data you have to create a client and server class based on available connection info.

Let's take a look at server class  : 

This is the client class : 

So finally, the sockets are now connected to each other and data transfer can be done easily using input and output streams of the socket.

Executor Framework in java

In this blog, we will tell you about the executor framework introduced in java since JDK 5 and how can we use it in our application development.

Executor framework introduced in version JDK 5 to perform concurrent execution in java and all the interfaces of this framework available in java.util.concurrent package.

Interfaces available in Executor framework given below:

i) Executor

ii) Executor Service

iii) Scheduled Executor Service

All these interfaces represent an asynchronous execution mechanism that is capable of executing multiple tasks concurrently in the background.

Executors is a factory class which is used to provide the instances of these interfaces such as for Executor Service class we need a pool of threads with size 10 so we can use Executors.new Fixed Thread Pool( size of thread pool ) method.

Creating an Executor Service:

ExecutorService executorService = Executors.newFixedThreadPool(10);

ExecutorService implementation class contains many methods but here we see an example of execute(Runnable) and submit(Callable) method, which contains runnable implementation class instance to execute in a concurrent way.

executorService.execute(new Runnable() {
 public void run(){
   System.out.println("Concurrent task");
          }
});

Callable is an interface just like Runnable but the difference is that Callable interface's abstract method call() can return Object type instance. While calling submit(Callable) method, it is returned Future object which contains the return value we can use get() of Future to get a return value.

Future future = executorService.submit(new Callable(){
    public Object call() throws Exception {
        System.out.println("Concurrent Callable");
        return "Callable Result";
    }
});

System.out.println("future.get() = " + future.get());

Now here we need to take one more action shutdown() method to shut down the executor service after all task completion but we have another method also to shutdown executor service such as shutdownNow() for immediate shutdown and await Termination() method will block the thread calling it until either the Executor Service has shut down completely and it is called after shutdown() and shutdown Now().

Conclusion: I hope you like this blog and I hope it is very useful for you in the future whenever you want to save your time to perform additional tasks in a concurrent way.

Thank you and Happy coding.
