Inspecting elements allows you to peek into the building blocks of a webpage or an application, revealing the HTML, CSS, and JavaScript responsible for its functionality and design. Why inspect? You can use this to identify UI issues, portability issues, and more. In this blog, you will learn the different methods of how to inspect elements on Android and how they help with mobile testing.

What is Inspect Element?

Inspect element is one of the developer tools available in the web browsers like Firefox, Google Chrome, Safari, and Internet Explorer. With Inspect Element, you can make temporary changes to the HTML and CSS of a web page that underlies the website’s content.

Following that, changes you make to the code are seen in your browser tab in real time. And don’t worry about damaging the site while you poke about in the code; your changes will only be visible on your screen and effective for the length of your session.

 In other words, without hurting other users, Inspect Element can provide you with a sort of “what if” experience. For example, you can use Inspect Element to change a text element’s color or add a new style rule to the page.

Inspect Element is a valuable tool for web developers, as it allows you to quickly test changes to your code without reloading the page. However, it’s also useful for non-developers who want to customize the appearance of a web page. For instance, you can use Inspect Element to remove an ad from a web page or change a website’s background color.

Inspect Element is merely a curiosity to the typical website visitor, perhaps worth very few minutes of their time. But this developer tool has a variety of benefits for web designers, programmers, and people who want to learn to program.

Benefits of Inspect Element

The benefits of inspect element include the following –

  • It’s helpful to have the ability to experiment with something if you want to truly grasp it. You can discover how a website’s code functions by fiddling with it using Inspect Element, which has this advantage. Let’s assume that you are new to programming. When you visit a website, you notice something about it that really grabs your interest. It can be something you’ve wanted to include in a page you’ve been working on, or it might be something innovative that you’ve never thought about. In either case, you want to know the code. Therefore, you utilize Inspect Element to observe what’s happening clearly.
  • Inspect Element lets you preview changes while still implementing them while developing your own page. It enables quick detection and correction of flawed code. You can modify any information on the page using the inspect element. Therefore, you can alter any text on a shared screenshot without using the outdated photo editor.
  • Inspect Element on rival pages can also give you a sense of the intensity of the keywords that are focused on if you’re interested in optimizing your page for improved search engine ranks which is an important component in digital marketing. The tool allows you to check the loading time of your website.

Inspecting an Element is Not the Same as Viewing the Source Code

Most web browsers have an indispensable tool for developers to see the DOM as seen by the browser itself. Various channels, websites, and forums allow Android users to ‘view source code’ and inspect an element directly, like inspect element on mobile chrome without debugging the operating system. However, it is important to understand that source code viewing does not equate to inspecting elements.

To read the source code on a mobile device, set the webpage URL with the prefix ‘view-source:’ as demonstrated below:

Example

The above image indicates that finding elements like this is difficult. The text editor you use to create the web application can be used to access it easily during the creation process.

The main goal of an inspection is to ‘inspect’ an element’s behavior and flaws. For example, breakpoints can be used to assess variable values before rendering a whole website. You can edit the element’s code from the web page by inspecting it and then refreshing the page to view the changes. Finally, if you are content, you can use the editor to make final code adjustments.

View source code may only be used to view the source code of the web application (like example 1). Thus, it cannot be used to verify any of the aforementioned reasons. Therefore, it is advisable not to use this approach for developers or testers.

Inspect Elements on Android Devices by Various Methods

Inspecting elements on Android for mobile app testing typically involves using developer tools that allow you to inspect and debug the application. Here are some ways on how to inspect elements using developer tools,

Using Chrome on Android

On your Android device, utilize Google Chrome to swiftly scan the components. You can use your desktop or laptop to remotely troubleshoot any component on your Android device.

Steps to follow –

Step 1 – Activate the Android device’s developer options.

Step 2 – Toggle USB Debugging on. As soon as the USB is connected, this initiates a debug mode.

Step 3 – Open Google Chrome and enter chrome:/inspect#devices in your deployment system.

Step 4 – Make sure Discover USB devices are turned on. This will display a list of every USB-connected device attached to the system.

Step 5 – When connected, you will notice a label box beside the device name. After entering the URL, click Open.

Step 6 – Next, click Inspect to the right of the URL.

However, this technique has the drawback of requiring you to test each other devices separately. This requires a lot of time and effort. Additionally, scaling is challenging because using this feature on many devices requires having your own device lab.

Using Android applications

We will learn how to inspect elements in Android without a computer using Android applications. You can find Just a few Android apps developed by developers available on Google Play. These can include the Webpage edit app, Edit HTML live app, and the Inspect, among others. These applications’ basic goal is to display the required element on the smartphone screen while enabling you to edit the element’s code to view the updated customized form.

In conclusion, because Android applications run on small screens, managing, changing, and reading complex web page scripts is challenging. Additionally, this approach necessitates continually downloading and deploying the application on each target device. Because the Android market is so fragmented and it is impractical to physically examine every Android device; this repeating process is annoying.

However, check out Android apps right now on the cloud using actual Android devices.

Using Android Developer Mode

A mobile website can also be inspected without any active stimulator using an Android device to detect bugs. 

Step 1 –  Enable Developer Mode in your Android. 

Tap on “About Phone” or “About Device” in the “Settings” section of your Android device to reveal the device’s information. You will be prompted to enable Developer Mode by tapping the “Build Number” several times.

Step 2 –  Set up Chrome Desktop

Connect your Android device to your development system (PC) after you enable Developer Mode on Android.  

Click on the checkmark next to the Discover USB devices option in the Chrome browser on your PC, then enter chrome://inspect/#devices in the navigation bar.

Step 3 – Open Chrome and inspect elements on Chrome

When you click on “Devices” in DevTools, you will see the Android device with the Chrome version installed. In the input bar saying “Open a tab with URL,” enter the website URL next to the Chrome version name and click “Open.”

You can inspect website elements by clicking the “Inspect” option under the device’s name.

Using Third-Party Application

Installing a third-party program can be necessary if you wish to simulate an Android device on your desktop to check elements. So how to inspect elements in an Android emulator? There are a lot of online platforms that allow us to emulate Android devices, such as BrowserStack.   

Using Remote Debugging tools

Developer tools provided by Google Chrome on the desktop allow you to access the DOM of web applications running on Android remotely. Live monitoring is available on the user’s computer. The Weinre open-source tool is another remote debugging tool that can be used on Android, iOS, Firefox OS, and Windows to debug web pages. 

Let’s have a brief study on how to inspect elements on Android using remote debugging tools – 

Remote Debugging Using Chrome Developer Tools

Chrome developer requires Chrome 32 or later updates, along with Android 4.0 + and Chrome on the device, and Android 4.4+ for app debugging and webview configuration.

Step 1 – Turn on USB debugging on the Android device by clicking Settings > Developer Options > USB debugging (device only).

Step 2 – Use a USB cord to connect the Android to a computer or launch an emulator locally.

Step 3 – Launch Chrome on your desktop after configuring your device and go to chrome:/inspect/.

Step 4 – Search for USB devices. Just click OK on confirmation popups if they arise. If the device is correctly attached, it will display as found, as seen below.

Click on the element to inspect. It also offers the ability to locate a page element. If you’re using an emulator, click on the search icon and then the relevant element.

Remote Debugging Using Weinre

Similar to “Chrome on Android,” Weinre is a remote debugging tool. Weinre functions as a client-target tool, with the client (the tool) being the PC and the target (the mobile device) being the platform where the application is being tested.

Components of Weinre – 

  • Debug server: Debug target and client both utilize the same HTTP server.
  • Debug client: A web inspector for the application, comparable to developer tools.
  • Debug target: Web application running on your Android device.

Setting Up Server – 

Step 1 -Use the command sudo npm -g install weinre to install weinre as a npm package. Your server is now ready with that information. Use the command weinre to launch it. It will start on the default port of 8080; you can modify it with the weinre-httpPort port number> command. Use weinre-help to explore further alternatives.

Step 2 – Access the server home page using http://<IP address of the server>:<port>/

Step 3 – Next – Open debug client using the http://<IP of the server> : <port>/client/#anonymous on your device.

Step 4 – To allow the server to access your device or emulator, connect it through WiFi to the network. Try using the device browser to reach the server’s home page URL. The connection to the server is confirmed when it opens.

Step 5 – Add JavaScript code to the page source so the debug server and target can communicate –

<script src=”http:// <IP address of the server>:

<port>/target/target-script-min.js”></script>

Step 6 – Start by opening your script-injected website in the device’s browser. Your debug client will show it in the Remote tab.

Using the Elements tab of the client, you can now debug your web page.
