Dev.Opera — Remotely Debugging Opera for Android


Now that Opera for Android is out, you’ll sometimes need to debug it, as there are differences in Standards support between Opera and Chrome for Android and Chrome on Android 4+ (<input type=color>, @supports, etc,).

Here’s how to connect Opera for Android to Chromium-based desktop browsers for remote debugging.

Preparing your desktop

You’ll be remotely debugging your phone from your desktop, so let’s get the desktop ready.

Install Android SDK

The first thing you’ll need is the Android SDK — download it and then put the kettle on; it’s a 400MB file.

Extract the files to a memorable location, such as /Users/your-user-name/adt or c:android/adt. If you choose something else, use that in the example steps below.

Windows users may need to install Device drivers. Linux and Mac users shouldn’t need to.

Install a Chromium-based browser

You’ll need a Chromium-based desktop browser. Use Opera 15+, Google Chrome, Chromium, or the Yandex browser.

Preparing your device

Ensure that you have a USB cable available to connect your Android device to your computer (the USB power cable should be fine) and Opera for Android installed on it (see the Opera for Android user guide for installation help, if needed.) Keep the phone disconnected from your computer just for now.

Note that you can’t remotely debug Opera Mini from desktop, as the rendering is done on our Mini servers and only displayed on the device. (Opera Mini FAQs)

Next, you need to enable USB debugging on your device. Check the “USB debugging” checkbox in Developer Options.

  • On Android 2.3, the option is under Settings > Applications > Development
  • On Android 4.0 and newer, it’s in Settings > Developer options
  • On Android 4.2 and newer, go to Settings > About phone and tap Build number seven times to get a message that says “congratulations! you are now a developer”. Returning to the previous screen shows previously-hidden developer options.

On Android 4.2.2 and higher, you’ll see a dialog asking whether to accept an RSA key. This is a security mechanism; accept the dialog.

When doing mobile debugging on Android it is also useful to check the “stay awake” option that you’ll find in the same place as the “USB debugging” option, so the device stays on while plugged into USB, but this isn’t mandatory.

Before moving on, connect your phone to your computer via the USB cable. If it was already connected, try disconnecting and reconnecting it, just to make sure the computer recognises the phone properly. You should see a message on the phone along the lines of “USB debugging connected” to indicate that things are proceeding successfully.

Connect desktop to device

Start Opera for Android, and enable debugging by entering opera:debug in your address bar and checking the “enable” checkbox in the resulting page, as seen below.

Now let’s get the debugger started:

In your computer’s terminal, navigate to the directory into which you extracted the Android SDK. Once there, navigate to sdk > platform-tools. Inside there you should see an executable called adb, which is an acronym for Android Debugging Bridge.

To start the debugging bridge, Type in the following terminal command:

adb forward tcp:9222 localabstract:com.opera.browser.devtools

You should see a message output along the lines of the following:

$ daemon not running. starting it now on port 5037* $ daemon started successfully

If you are using Linux or Mac OSX, you will have to add ./ at the start of the terminal command above, to tell terminal to look for adb inside the current directory, and not your Path. To avoid having to do this every time, you could add a path to adb in your actual path. You can do this by placing a line in your ~/.profile or ~/.bash_profile like so:

export PATH=/Users/your-username/path-to-adk-folder/adt/sdk/platform-tools/:$PATH

You’ll then need to restart the Terminal, or open a new tab.


Your device and desktop browser should now be connected and able to send information to each other across the debugging bridge. To begin debugging, go to localhost:9222 in your desktop browser. You’ll see a list of inspectable tabs (note that if you open a new tab on the device, you’ll need to refresh the Inspectable Tabs page):

If you instead get a message saying that the server sent no data, or similar, you might have typed in the Terminal command incorrectly. Go back to the Terminal, check it, and try again. There is a very small chance that, if it didn’t work, the bridge isn’t running, but its process still is. If you still have a problem upon retrying the Terminal command, you might have kill the process directly. This can be done by first typing the command ps -A to bring up a list of running processes, finding the right process ID (the one with “adb fork-server server” in the CMD column), and then killing it with kill _your-process-id_.

Clicking on one of the inspectable tabs brings up the web inspector full-screen, allowing you to debug, change the page, and all sorts of amazing things:

and the changes are immediately visible on your device:

What about Opera Dragonfly?

The current version of Opera Dragonfly (which is Presto-based) won’t work with Chromium, because the protocols are radically different.

Updated 5 Q&As on Opera for Android

A couple of months ago, we introduced a fresh new look to Opera for Android. Today, thanks to your feedback, 🙂 we are rolling out some tweaks to the user interface and new features. Here are some things you might be wondering about with your new-look browser:

“How can I turn on data savings?”

When enabled, Opera will compress all webpages to load fewer megabytes, which will also make your browsing even faster.

Go to Settings ⚙, located in the hamburger menu in the bottom-right corner of your screen, tap on Data savings, then tick the box beside Enable.

Once you turn this feature on, you’ll be able to Block ads and choose the Image quality you want Opera to load in every webpage you visit.

“How can I change my default search engine?”

Switching search engines is still the same in this version. Tap Opera’s search bar and then the Google icon to the left to display all various options. Tap on the one you prefer to make it the default.

In case you didn’t notice, Opera now supports Voice search. Tap on the mic icon to the right of Opera’s search bar and say aloud what you want to search. It will immediately look up your inquiry using your preferred search engine.

“Where can I find my offline pages, bookmarks, history and downloads?”

As you might have noticed, Opera’s user center is sporting a new icon design and a fresh coat of red paint. Tap on the hamburger button in the bottom-right corner of your screen to find your browsing history, bookmarks, saved pages and downloads.

“Where can I sign in to sync bookmarks and tabs?”

Sync your bookmarks and tabs from your previous Opera browser and across your phones and computers. Tap on the hamburger button in the bottom-right corner of your screen, and choose Sign in. Log in with your Opera account, or create a new one, to start syncing.

To find your open tabs, go to the tab manager located on the bottom bar and tap on the cloud icon at the bottom-left corner of your screen.

“How can I translate a website, add it to my Speed Dial, bookmark it or save it to read offline?”


When browsing a website, find all these features placed on the three-dots menu in the upper-right corner of your screen. Tap on it to choose between translating a website, adding it to your Speed Dial, bookmarking it, saving it for when you have no internet connection or even saving it to your Android home screen.

What are your thoughts on Opera for Android’s new look and features? We hope you love them as much as we do. 😉 If you have any other questions, drop us a line in the comments below or tweet us @opera and our ninjas will come to your rescue!
