Elvis Operator is a most frequently used operator which is denoted by “?:”, its appropriate use is when an object is declared nullable.

Elivs Operator is used to check the null object and assign something if it is null.

It's similar to a struct or a record in other programming languages. A tuple is defined using the keyword "pair" or "triple" followed by the types of the items inside the parentheses. For example, a pair of integers can be defined as:<pre><code class="language-plaintext">val pairInt: Pair&lt;Int, Int&gt; = Pair(1, 2)</code></pre> You can access the elements of a tuple using the properties first and second.<pre><code class="language-plaintext">val first = pairInt.first
val second = pairInt.second
// or
val(first,second) = pairInt</code></pre> A triple of integers, string, and boolean can be defined as:<pre><code class="language-plaintext">val triple: Triple&lt;Int, String, Boolean&gt; = Triple(1, "Hello", true)</code></pre>&nbsp;You can access the elements of a triple using the properties component1, component2, component3.<pre><code class="language-plaintext">val component1 = triple.component1()
val component2 = triple.component2()
val component3 = triple.component3()</code></pre>Tuples are useful when you need to return multiple values from a function, or when you want to group related data together without creating a separate class for it.

In Kotlin, a tuple is a data structure that holds a fixed number of items, where each item can have a different type. 

Kotlin tuple is a data structure that holds a fixed number of items, where each item can have a different type.

The Android Navigation component is a part of the Android Jetpack suite of libraries that provides a powerful and flexible way to manage navigation in an Android app. It helps you design a consistent navigation structure and implement navigation in a way that is easy to maintain and test.The <code>navargs</code> class is generated automatically by the Android Navigation component based on the arguments that are defined in the navigation graph. It contains fields for each of the arguments that are passed to the destination, as well as getter and setter methods for those arguments. To use SafeArgs in the Android navigation component, you will need to follow these steps:1. Add the SafeArgs plugin to your project-level <code>build.gradle</code> file:<pre><code class="language-plaintext">buildscript { 
	dependencies 
		{ // Add this line 
			classpath "androidx.navigation:navigation-safe-args-gradle-plugin:$nav_version" 
		}
	}</code></pre>&nbsp;OR on Latest Android Project:<pre><code class="language-plaintext">
plugins {
 	// Add this line 
 id 'androidx.navigation.safeargs.kotlin' version '2.5.1' apply false
}</code></pre>2. Apply the SafeArgs plugin to your app-level <code>build.gradle</code> file:<pre><code class="language-plaintext">apply plugin: "androidx.navigation.safeargs"</code></pre>OR on Latest Android Project:<pre><code class="language-plaintext">plugins {
	// Add this line
 id 'androidx.navigation.safeargs.kotlin'
}</code></pre>3. Define the arguments for your destination in the navigation graph. You can do this either by using the Navigation Editor in Android Studio or by manually adding them to the navigation XML file. For example:<pre><code class="language-plaintext">&lt;fragment
 android:id="@+id/SecondFragment"
 android:name="com.Abdulqa.androidnavigationsafeargsexample.SecondFragment"
 android:label="@string/second_fragment_label"
 tools:layout="@layout/fragment_second"&gt;

 &lt;argument
 android:name="stringData" // it can be any name 
 app:argType="string" /&gt; // type of argument list shared below
&lt;/fragment&gt;</code></pre>4. Build your project to generate the SafeArgs classes. These classes will be located in the <code>app/build/generated/source/navigation/</code> directory and will have the same package as your app.5. Use the generated SafeArgs classes to pass data between destinations. For example:<pre><code class="language-plaintext">val action = FirstFragmentDirections.actionFirstFragmentToSecondFragment("Hello from SafeArgs!")
findNavController().navigate(action)</code></pre>6. In the destination fragment, you can retrieve the argument value using the generated SafeArgs class:<pre><code class="language-c">private val args: SecondFragmentArgs by navArgs()

binding.textviewSecond.text = args.stringData</code></pre>That's it! You have successfully used SafeArgs in your Android navigation component to pass data between destinations. &nbsp;<h2>Android SafeArgs Navigation supported Argument Types: &nbsp;</h2><figure class="table"><table style="border:2px solid hsl(0, 0%, 60%);"><thead><tr><th style="border:1px solid hsl(0, 0%, 60%);height:48px;padding:var(--devsite-table-heading-padding, 8px);">Type</th><th style="border:1px solid hsl(0, 0%, 60%);height:48px;padding:var(--devsite-table-heading-padding, 8px);">app:argType syntax</th><th style="border:1px solid hsl(0, 0%, 60%);height:48px;padding:var(--devsite-table-heading-padding, 8px);">Support for default values</th><th style="border:1px solid hsl(0, 0%, 60%);height:48px;padding:var(--devsite-table-heading-padding, 8px);">Handled by routes</th><th style="border:1px solid hsl(0, 0%, 60%);height:48px;padding:var(--devsite-table-heading-padding, 8px);">Nullable</th></tr></thead><tbody><tr><td style="border:1px solid hsl(0, 0%, 60%);padding:var(--devsite-table-cell-padding, 7px 8px 8px);vertical-align:top;">Integer</td><td style="border:1px solid hsl(0, 0%, 60%);padding:var(--devsite-table-cell-padding, 7px 8px 8px);vertical-align:top;">app:argType="integer"</td><td style="border:1px solid hsl(0, 0%, 60%);padding:var(--devsite-table-cell-padding, 7px 8px 8px);vertical-align:top;">Yes</td><td style="border:1px solid hsl(0, 0%, 60%);padding:var(--devsite-table-cell-padding, 7px 8px 8px);vertical-align:top;">Yes</td><td style="border:1px solid hsl(0, 0%, 60%);padding:var(--devsite-table-cell-padding, 7px 8px 8px);vertical-align:top;">No</td></tr><tr><td style="border:1px solid hsl(0, 0%, 60%);padding:var(--devsite-table-cell-padding, 7px 8px 8px);vertical-align:top;">Float</td><td style="border:1px solid hsl(0, 0%, 60%);padding:var(--devsite-table-cell-padding, 7px 8px 8px);vertical-align:top;">app:argType="float"</td><td style="border:1px solid hsl(0, 0%, 60%);padding:var(--devsite-table-cell-padding, 7px 8px 8px);vertical-align:top;">Yes</td><td style="border:1px solid hsl(0, 0%, 60%);padding:var(--devsite-table-cell-padding, 7px 8px 8px);vertical-align:top;">Yes</td><td style="border:1px solid hsl(0, 0%, 60%);padding:var(--devsite-table-cell-padding, 7px 8px 8px);vertical-align:top;">No</td></tr><tr><td style="border:1px solid hsl(0, 0%, 60%);padding:var(--devsite-table-cell-padding, 7px 8px 8px);vertical-align:top;">Long</td><td style="border:1px solid hsl(0, 0%, 60%);padding:var(--devsite-table-cell-padding, 7px 8px 8px);vertical-align:top;">app:argType="long"</td><td style="border:1px solid hsl(0, 0%, 60%);padding:var(--devsite-table-cell-padding, 7px 8px 8px);vertical-align:top;">Yes -

Pick a Contact from Contact List of Android Phone

Rooting an Android phone or tablet basically lets you go beyond the device's core and explore its system, giving you more freedom. After rooting, you can reach completely inaccessible files and apps that weren't available before, like getting around any restrictions your manufacturer or carrier may have imposed. Rooting your phone is a great way to change its look and feel of it. If you do that, you'll need to download a custom ROM, which is a modified version of Android. Before installing this new software, you should back up your phone's unique ID and data.&nbsp;<h2>You might be wondering why we don't root, and we have an answer for you.</h2>&nbsp;There are four potential drawbacks to rooting an Android device.Manufacturers or carriers will void your warranty if you root the device, so keep that in mind before making the decision to root. However, it's easy to unroot the device when you need to send it back for repairs. If you have a software backup made, simply flash the device using this backup and it’ll be as good as new. Bricking your phone: If you make a mistake during the rooting process, it could corrupt your device. As long as you follow instructions exactly, though, and follow instructions that are up to date, there is little risk of bricking your phone. You can be sure you're doing everything correctly by researching the custom ROM and following up on the guide's details before you flash. By being careful, you shouldn't have to worry about bricking your smartphone. Rooting may introduce some security issues. Depending on the services or apps you use on your device, it could create a security vulnerability. Malware writers also use rooted devices to steal data or send harmful web traffic to other devices. Disabled apps: Apps that serve copyrighted TV shows, movies, and other content are disabled on rooted devices — Sky Go, Virgin TV Anywhere and Netflix will not work. Financial apps like Google Pay and Barclays Mobile Banking will not work with rooted devices, either.&nbsp;<h2>Start Rooting</h2>&nbsp;While you can usually boot your device into recovery mode and clear its cache, it’s better to create a full backup of all the data you have on the phone before flashing a new ROM. You should also always back up the ROM on your phone before upgrading it since recovering the data from a failed upgrade would take hours.To enable USB debugging, you need to open your device's Settings app, scroll to Developer Options, and toggle on USB Debugging. If you can't see the Developer Options in the list, follow these steps to make them available.Follow these steps to find your 'Build Number' in the Settings app. The exact path to your Build Number will depend on your phone - it'll usually be found in the Software info.<ol style="list-style-type:decimal;"><li>You'll need to tap the Build Number seven times to see the Developer Options page. You will be prompted for your security passcode.</li><li>Tap the Backspace key to see your new developer options.</li><li>Tap Developer Options.</li><li>Check to see if USB debugging has been enabled.</li><li>Allow OEM UNLOCKING</li><li>Unlock your bootloader</li></ol>Before you start, we'll need to unlock your device's bootloader. If this is the first time you've heard the word bootloader, don't worry! It's simply the program that loads your operating system. It determines which apps will be running during your phone or tablet's startup process. Collectively, this is called software loading.Some manufacturers require you to get a key to unlock the bootloader if you want to root or install other software. Some manufacturers, like Motorola, HTC, LG, and Sony, provide step-by-step instructions on how to do so. However, they only allow it if you register for a developer account (which can be kind of pricey).Huawei and Honor devices are now locked and can't be unlocked, but this third-party service can do the job for you. Huawei rescinded the ability to request unlock codes in July 2018, but DC-Unlocker remains a viable option for rooting your phone.When you're ready to unlock your device, you'll need to put it in fastboot mode. The steps vary depending on the phone, though on most devices simply rebooting the device into fastboot mode and holding down Volume Down and Power buttons for ten seconds works (HTC phones require that you hit the Volume Down key and press the Power button to select).Calling all developers! The Android SDK is essential for building quality apps and games that run smoothly on your device. What you need to do first is boot into Fastboot mode using the necessary button sequence on your phone, tablet, or connected computer. Next, head to the directory where you saved your SDK files (having done so earlier). Once you're in there, open a command prompt window by holding down Shift + Right-clicking anywhere inside the folder and then selecting "Open a Command Prompt here." When prompted about a code and login information, paste it in the box on the manufacturer's website and submit. Shortly afterward, look for an email with a key and supplementary information from your device manufacturer.&nbsp;

If you're not familiar with rooting, it involves giving the user superuser privileges. We'll explore the topic

Smart watches, Yay or nay?

Without an official design release or statement by Apple, any information about the iPhone 14 – Apple’s flagship phone set to launch in September 2022 – is still reliant on rumors or leaks. There are still a few months to the launch of the latest variant of the iPhone, but these rumors have been around for a long time – possibly because Apple is said to be planning on some big changes. Let’s look into what the news until now is about the product’s specifications, outlook, and new additions.<h3>&nbsp;</h3><h3>Specifications:</h3><ul><li>Chipset – Apple analyst Ming-Chi Kuo the Pro variant will get an upgraded chip, the A16, which will be faster. It is unclear yet if the standard model will feature the A16.&nbsp;</li><li>RAM – The Pro variant is said to have 8GB, an upgrade from the 6GB being offered on iPhone 13. However, it is unsure whether the non-Pro variant will be bumped to 6GB from the usual 4GB.</li><li>Camera – Whilst the standard model is rumored to have the same camera as iPhone 13 except for improvements on the ultra-wide camera, the Pro models will boast a 48-megapixel wide-angle camera as well as 8K video capturing capability.</li><li>Modem – The new iPhones will feature the Qualcomm Snapdragon X65 modem which will improve connectivity and power efficiency. The modem is the world's first 10 Gigabit 5G modem and antenna system for smartphones.</li><li>Wi-Fi – iPhone 14 will have WiFi 6E connectivity, giving it a performance boost (higher speeds and lower latency) over previous versions.</li><li>Storage – Although not confirmed, the new iPhone might come with a 2TB storage option as opposed to the 1TB maximum in iPhone 13. &nbsp;</li></ul><h3>Outlook:</h3><ul><li>Front – It is rumored that iPhone 14 Pro will come without the notch at the top, and instead might only have a punch-hole and/or pill-shaped front camera. The face-detection hardware might have to change according to this design modification, but it isn’t confirmed whether Apple will look into that. The standard model is set to feature the notch, the same as iPhone 13.&nbsp;</li><li>Sides and Back – Leaked renders of the design revealed that the back/sides will be the same as iPhone 13. However, there are new developments; a new purple color option will most likely be offered for all variants, and the frame might be shifted to titanium. &nbsp;</li></ul><div class="raw-html-embed"><div id="amzn-assoc-ad-108afcae-4d0c-4d97-aeb6-b5fa516770db"></div><script async="" src="//z-na.amazon-adsystem.com/widgets/onejs?MarketPlace=US&amp;adInstanceId=108afcae-4d0c-4d97-aeb6-b5fa516770db"></script></div><h3>What’s New:</h3>Most of what we know up until now points towards the fact that the majority of what’s new is in the Pro version of the iPhone 14. The first major thing is the A16 chip – only to be offered in Pro and Pro Max whereas the standard variant will utilize the A15, the same as iPhone 13. Similarly, the 8GB RAM option will be introduced for the first time, but only for 14.&nbsp;The sizes offered will also change, with the mini variant being discontinued after its unimpressive sales. The Max options will be 6.7 inches, and the standard-sized options will be 6.1 inches.The price is also set to increase in light of inflation across the globe as well as supply-chain shortages that set in due to the Covid-19 pandemic. &nbsp;
