From the <a href="http://developer.android.com/tools/help/adb.html" rel="noreferrer">adb docs</a>

<blockquote>
 When you connect a device running Android 4.2.2 or higher to your
 computer, the system shows a dialog asking whether to accept an RSA
 key that allows debugging through this computer. This security
 mechanism protects user devices because it ensures that USB debugging
 and other adb commands cannot be executed unless you're able to unlock
 the device and acknowledge the dialog. This requires that you have adb
 version 1.0.31 (available with SDK Platform-tools r16.0.1 and higher)
 in order to debug on a device running Android 4.2.2 or higher
</blockquote>

So, unplug, wait, replug in the cable, and hit ok (on modal dialog that appears on your device)

If you hit cancel, the device will show up as offline via <code>adb devices</code>

Try pre-installing the drivers for your devices. Make sure, under Windows, that your device is recognized in the System control panel first.

I use Windows 7 and my Galaxy Nexus wouldn't be recognized by the system until I installed the device drivers before plugging them in. From the comments, this works on Windows 8 as well.

Check if you have installed android-adb-tools in Ubuntu. If you do, the adb tool may be old. Uninstall and make an alias to the latest adb tool you download with the ADB plugin. To check the adb version do "adb version" if it's 1.0.29 is the old, the latest and working for Android 4.2.2 is 1.0.31.

I made a lot of stuff until i realized this.

<li>Tried WiFi but it said it was offline </li>

What fixed it for me was changing the device connection from Mass Storage to MTP. To do so, with the phone unplugged you go into -

blocks|key|294235|text|我在cm10.1夜间基于机器人仿生构建的解决方案是在更新最新的usb驱动程序之后，使用海量存储选项(而不是用于USB计算机连接的MTP选项)，然后取消检查和重新检查开发人员选项，即“亚行网络上的亚行”选项。然后它弹出了RSA对话框。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|294236|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

My solution used on cm10.1 nightly build on droid bionic, was after updating the newest usb drivers, using the Mass storage option (instead of the MTP option for USB computer connection), then unchecking and rechecking in developer options, "ADB over network" option. Then it did the RSA pop up dialog.

For me the best solution was: 

Update the Android SDK via the SDK-Manager. Removing the '.android' folder in my usr directory ( Windows 7 ) and re-plugging the device back in. Worked flawlessly due to the ADB RSA key issue. I had an older version of ADB that I stashed into c:\windows\system32\ due to not wanting to install an entire freakin SDK when all I wanted was a command prompt. Good ol' Google, the new Microsoft.

<li>go to Settings => about this device => click several times on "Version number", that is to say something like "JDQ39.I9505XXBHYTGKDD" (not android version or anything else) ; here you will see that Google or Samsung have a lot of humour as you have to click until multiple times until having a toast displaying "You are at few clicks from being a developer" ; after something like 10 clicks, you have a toast "You are a developer"</li>
<li>Go "Development options" (in the "More" tab (rigjt tab of settings menu)) ; be sure that "USB debugging" is checked.</li>
</ul>

And it works ! Eclipse can see your S4(or any other device) 4.2.2 !

In case it helps someone else arriving here, I had this problem with a ZTE phone.

I tried installing the driver based on the offical list <a href="http://developer.android.com/tools/extras/oem-usb.html" rel="nofollow">here</a> but in Device Manager the driver was marked as not installed correctly.

In the end I found the way to make this work was:

<ol>
<li>Press Menu Button</li>
<li>Choose "Connect to PC"</li>
<li>Choose "Default connect type"</li>
<li>Choose "Install Driver"</li>
<li>Plug in phone and on PC select option to install the driver</li>
<li>Then change "Default connect type" to "PC software"</li>
</ol>

After doing this I was able to do:

<pre><code>adb kill-server
adb start-server
adb devices
</code></pre>

and view my device.

Connect your phone via cable your PC and wait.

With the new update to 4.2.2 to my Galaxy Nexus and Nexus 7, I can't find both my devices under <code>adb</code>.

These are the steps I took:

<ul>
<li>Updated to 4.2.2</li>
<li>Updated ADT and SDK through the SDK Manager</li>
<li>Checked ADB version, it's at 1.0.31</li>
<li>Restarted PC and Tablet and Phone numerous times</li>
</ul>

When I run <code>adb devices</code>, it's just blank. I have the same issue on Windows 8 and on Ubuntu 12.10, but on Ubuntu it shows my device and it says <code>offline</code>.

Are there any other steps I can take?
