<p>Hello techies, this blog will not be more about an overview how to do wireless debugging in Android Studio but would be more of a quick solution for those who have searched through the internet to fix it in Android Studio.</p><p>So, basically you can find all the way to do wireless debugging in Android studio <a target="_blank" href="https://developer.android.com/tools/adb#connect-to-a-device-over-wi-fi" alt="here">here</a> - but in this blog I would be showing you the simplest and easiest way to do things, which worked for me pretty well.</p><p>So let's dive into this. In this tutorial to connect your device wirelessly for debugging we would be using the <code><span style="color: rgb(140, 140, 140);">adb</span></code> commands - if your terminal doesn't know it then add it to the path or install the android-platform-tools. You can go through the plenty of articles on internet to set it up for you. Once <span style="color: rgb(140, 140, 140);">adb</span> command is available on your terminal we're good to go further.</p><h2>First things First<br></h2><ul><li>On your mobile device enable USB Debugging.</li><li>Then connect the device using USB to Android studio which you do usually for the debugging over USB.</li></ul><h2>Make your device ready</h2><ul><li>Now open up the terminal and list out the devices using the command <span style="color: rgb(140, 140, 140);">adb devices -l</span></li><li>Now, if you can see your device in the terminal, the we are good to go.</li><li>Run this command - <span style="color: rgb(140, 140, 140);">adb tcpip 5555.&nbsp;</span>This will put the device into TCP/IP mode listening on port 5555. Now remove the USB from device.</li></ul><h2>Final Step</h2><ul><li>In your device, get the IP of the device by going into settings, and then in <span style="color: rgb(140, 140, 140);">about phone &gt; status &gt; IP address</span>. Or rather search for IP in settings as different devices it's location may vary. Whole point here is to get the IP of the device.</li><li>Now, the final step - run the command - <span style="color: rgb(140, 140, 140);">adb connect <em>device_ip</em>:5555</span>. This will connect the device wirelessly.</li></ul><p>So, at this point, you would be able to see the device connected, also you can check it by running command <span style="color: rgb(140, 140, 140);">adb</span> devices and your device would be listed there.</p><p>Congratulations! you have setup the wireless debugging in Android Studio.</p><p>&nbsp;If you really liked this blog, do checkout other blogs, and stay tuned!</p><p>Happy Wireless Debugging!!</p>

How to do wireless debugging in Android Studio

<p>Hey there, fellow developers! Remember when we talked about <a href="https://www.dev-akash.in/blogs/edge-detection-in-opencv" alt="finding edges in images" target="_blank" class="on">finding edges in images</a>? Well, today, we're diving deeper into a related concept: contour detection. Think of it as finding and outlining shapes in pictures – pretty cool, right?</p><h2>From Edges to Contours: A Seamless Transition</h2><p>In our previous discussion on <a href="https://www.dev-akash.in/blogs/edge-detection-in-opencv" alt="edge detection" target="_blank">edge detection</a>, we learned how to detect the boundaries between different elements in an image. Now, contour detection takes these boundaries a step further, helping us to not only detect edges but also outline and identify the shapes formed by those edges.</p><h2>What Are Contours?</h2><p>Contour detection is like being a shape detective. It helps us find and outline objects in images. These outlines are called contours, and they're like the borders that separate one thing from another. In a black-and-white picture, contours highlight the boundaries of objects, making them stand out.</p><h2>How Does Contour Detection Work?</h2><p>Let's break it down. Imagine you have a black-and-white image. Contour detection looks for continuous white areas against a black background. It's like connecting the dots between pixels to outline shapes.</p><h2>Using OpenCV for Contour Detection</h2><p>Now, let's explore some additional options available for the <code>cv2.findContours()</code> function:</p><pre>import cv2<br><br><span style="color: rgb(241, 95, 95);"># Read the image</span><br>image = cv2.imread('your_image.jpg')<br><br><span style="color: rgb(241, 95, 95);"># Convert the image to grayscale</span><br>gray_image = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY)<br><br><span style="color: rgb(241, 95, 95);"># Find contours<br># The second argument specifies the contour retrieval mode.<br># Options include cv2.RETR_EXTERNAL, cv2.RETR_LIST, cv2.RETR_CCOMP, and cv2.RETR_TREE.<br># We use cv2.RETR_EXTERNAL to find only the outer contours of objects.<br># The third argument sets the contour approximation method.<br># Options include cv2.CHAIN_APPROX_NONE, cv2.CHAIN_APPROX_SIMPLE, cv2.CHAIN_APPROX_TC89_L1, and cv2.CHAIN_APPROX_TC89_KCOS.<br># We use cv2.CHAIN_APPROX_SIMPLE to compress horizontal, vertical, and diagonal segments.</span><br>contours, _ = cv2.findContours(gray_image, cv2.RETR_EXTERNAL, cv2.CHAIN_APPROX_SIMPLE)<br><br><span style="color: rgb(241, 95, 95);"># Draw contours on the original image</span><br>cv2.drawContours(image, contours, -1, (0, 255, 0), 2)<br><br><span style="color: rgb(241, 95, 95);"># Display the result</span><br>cv2.imshow('Contours', image)<br>cv2.waitKey(0)<br>cv2.destroyAllWindows()<br></pre><h3>Understanding Additional Options</h3><p>In the code above, let's take a closer look at the additional options available for the <code>cv2.findContours()</code> function:</p><ul><li><strong>Contour Retrieval Modes (cv2.RETR_XXX):</strong> <ul><li><code>cv2.RETR_EXTERNAL</code>: Retrieves only the external contours. Useful for most applications where you only need the outer boundaries of objects.</li><li><code>cv2.RETR_LIST</code>: Retrieves all contours without any hierarchical relationships.</li><li><code>cv2.RETR_CCOMP</code>: Retrieves all contours and organizes them into a two-level hierarchy. Useful for more complex shapes.</li><li><code>cv2.RETR_TREE</code>: Retrieves all contours and reconstructs a full hierarchy of nested contours.</li></ul> </li><li><strong>Contour Approximation Methods (cv2.CHAIN_APPROX_XXX):</strong> <ul><li><code>cv2.CHAIN_APPROX_NONE</code>: Stores all contour points.</li><li><code>cv2.CHAIN_APPROX_SIMPLE</code>: Compresses horizontal, vertical, and diagonal segments and leaves only their endpoints.</li><li><code>cv2.CHAIN_APPROX_TC89_L1</code> and <code>cv2.CHAIN_APPROX_TC89_KCOS</code>: Apply the Tangent Chain approximation algorithm to further compress contours.</li></ul> </li></ul><p>Experimenting with different options allows you to fine-tune contour detection according to the specific requirements of your project. So, feel free to explore and find the best settings for your application!</p><h2>Drawing Contours: Bringing Shapes to Life</h2><p>After detecting contours, we often want to visualize them on the original image. This is where the <code>cv2.drawContours()</code> function comes into play. Here's a simple explanation of how it works:</p><ul><li><strong>cv2.drawContours(image, contours, contourIdx, color, thickness):</strong> <ul><li><code>image</code>: The original image on which you want to draw contours.</li><li><code>contours</code>: The list of contours detected using <code>cv2.findContours()</code>.</li><li><code>contourIdx</code>: Index of the contour to draw. Use <code>-1</code> to draw all contours.</li><li><code>color</code>: Color of the contour lines (BGR format).</li><li><code>thickness</code>: Thickness of the contour lines.</li></ul> </li></ul><p>By using <code>cv2.drawContours()</code>, you can visually represent the contours found in the image, making it easier to analyze and understand the detected shapes.</p><h2>What Can You Do with Contours?</h2><p>Contour detection opens up a world of possibilities. You can use contours for object detection, shape analysis, and even creating special effects in images. With a bit of creativity, you can do amazing things!</p><h2>Conclusion</h2><p>Contour detection in OpenCV offers a wide range of options to suit various image processing tasks. By understanding how contours work and how to use the <code>cv2.findContours()</code> function, you gain greater control over the contour detection process, enabling you to extract valuable information from images with precision and accuracy.</p><p>So, roll up your sleeves, dive into the documentation, and start experimenting with contours! Happy coding!</p>

Adding Social Media Share Links to Your React App

<p>​Hey there, tech enthusiasts! Today, we're going to chat about a common task in the world of Java development: converting a .keystore file to a .jks file. Don't worry if you're not sure what that means – we'll break it down in simple terms.</p><p>First things first, what are these files? Well, a .keystore file and a .jks file are both used in Java applications to store security certificates and private keys. They're crucial for securing your applications and data. Sometimes, you might need to switch between these formats for various reasons, and that's where the conversion process comes into play.<br></p><p>So, how do we do it? Let's walk through the steps:<br></p><ol><li><strong>Open a Terminal or Command Prompt:</strong> To begin, you'll need to access your command-line interface. Don't worry, it's not as daunting as it sounds – it's just a way to interact with your computer using text commands.<br>  </li><li><strong>Navigate to the Directory:</strong> Use the cd command to navigate to the directory where your .keystore file is located. For example:&nbsp;<br><br>                    <pre>cd path/to/your/keystore</pre> </li><li><strong>Convert the File:</strong> Now, it's time to perform the conversion. Use the keytool command, which is a utility provided by Java for managing keystores and certificates. Here's the command you'll need: <br><br>            <pre>keytool -importkeystore -srckeystore yourfile.keystore -destkeystore yourfile.jks -srcstoretype JKS -deststoretype JKS</pre>Make sure to replace yourfile.keystore with the name of your .keystore file and yourfile.jks with the desired name for your .jks file. </li><li><strong>Enter Passwords:</strong> During the conversion process, you may be prompted to enter passwords for both the source and destination keystores. Simply type them in and hit Enter.<br></li><li><strong>Confirmation:</strong> Once the process is complete, you should see a confirmation message indicating that the conversion was successful.<br></li></ol><p>And that's it! You've successfully converted your .keystore file to a .jks file. See, it wasn't so hard, was it?<br></p><p>Remember, while this process is relatively straightforward, it's always a good idea to double-check your work and ensure that your certificates and keys are properly secured.<br></p><p>Now, go ahead and give it a try. Happy coding!<br></p>
