Device appears to be offline. Restarting the device may fix the problem.

[Nabren]

With Flash Builder 4.7 and Flex SDK 4.6 with AIR SDK 3.6 after my Google Nexus 10 upgraded to Android 4.2.2 I now get this error when attempting to launch to the device from Flash Builder:

Device appears to be offline. Restarting the device may fix the problem.

It showed Adobe AIR as Not Installed so I uninstalled it from the device and that didn't fix anything. I have tried everything. Rebooting the device. Rebooting Flash Builder. Rebooting Windows. Nothing helps.

Anyone know how to fix this?

[Colin Holgate]

Have you enabled developer access on the device?

[Nabren]

Yes. It was enabled before the update and working fine when lauching from Flash Builder with 4.2.1 installed. I checked after the update and everything seems to be enabled on the device.

[Danakh]

I got the same problem with my nexus 7. 4.2.2 seems to protect a little more USB debugging ( http://www.androidcentral.com/semi-pro-tip-android-422-here-your-android-sdk-might-need-updating )

But even with updated android SDK (and accepting the RSA key on my nexus), flash builder still fail to connect ... I guess we need a patch on flash builder

[Nabren]

That definitely seems like the culprit - hopefully this is patched/fixed very soon!

[mmah-umd]

I can verify Danakh's issue on a galaxy nexus with 4.2.2. On a Mac, the updated adb and aapt allow me to access the device over usb and install applications, but everytime I build a mobile application, Flash Builder appears to start an out-of-date adb server.

Just to add to this.

For Flash Develop 4.3.0RTM

I had to also copy abd and dlls into the folder

FlashDevelop/Tools/android/platform-tools

[ethierse · Accepted solution]

Same boat,

from <android_fresh_updated_sdk>\android-sdk\platform-tools

copy theses files : aapt.exe, adb.exe, AdbWinApi.dll, AdbWinUsbApi.dll and dx.jar (under lib rep)

and paste into <flex_Sdk-Air3.6>\lib\android\bin

To check, tape in cmd

$ adb.exe version, you should have 1.0.31 instead of 1.0.26

Voilà!

[Nabren]

That was it! Thank you. Hopefully they will release a new AIR SDK with the proper files soon to make this easier for everyone else!

Wow just got 4.2.2 on my GNex and here I am too running into this. Really hope Adobe gets a fix out asap.

edit:

@ethierse Thank you for saving the day. I seriously don't know what I wouldn't done today if you didnt post that fix. Thanks again!

[Guest]

@ethierse actually, i thought i had it fixed with what your post suggested. But now I keep getting "dx tool failed"

im on mac 10.7.5 and everything worked 100% before i updated my GNex to 4.2.2 today

how can i get past this?

edit SOLVED: ok what I had to do is keep my OLD dx.jar file. All I had to do to get this working on my mac was copy over the aapt file and adb file. maybe things are different on mac. hope this helps others out.

[thx1138]

What is android_fresh_updated_sdk and where do I get it?

[Danakh]

You can download the SDK here : http://developer.android.com/sdk/index.html

(select existting IDE)

This also recently happened first with my Nexus 10 then with the Galaxy Nexus so I had to fix it, was on Windows, for me the location specified didn't work out.  I searched for adb.exe elsewhere and found another directory containing it where I replaced the mentioned files.  On my system the folder was:

"C:\Program Files\Adobe\Adobe Flash Builder 4.7 (64 Bit)\eclipse\plugins\com.adobe.flash.compiler_4.7.0.349722\AIRSDK\lib\android\bin"

Just to make note, the first place that I had tried but didn't work out was:

"C:\Program Files\Adobe\Adobe Flash Builder 4.7 (64 Bit)\sdks\4.6.0\lib\android\bin"

[rlowke]

On MAC,

copy

android-sdk-macosx/build-tools/17.0.0/aapt

and

android-sdk-macosx/platform-tools/adb

into

/Adobe Flash Builder 4.7/eclipse/plugins/com.adobe.flash.compiler_4.7.0.349722/AIRSDK/lib/android/bin

You should be replacing old versions of aapt and adb in that folder.

[jazz_o_miny]

Thanks. It helped me. FB 4.7 was using the AIR SDK from the eclipse plugin and I pasted the files in sdk 4.6

[Sunil Kumar Sah]

Hi,

Just download latest Android SDK from google and replace below files in Adobe Flash Builder bin folder. You can search and find folder location and replace below mention latest files in same folder.

aapt.exe

adb.exe

AdbWinApi.dll

AdbWinUsbApi.dll

dx.jar

[Howitzer21]

Where's a good spot to get the right versions of those files from off the Internet?  I didn't have them on my computer, and when I tried to use the Android SDK Manager, the versions I installed didn't appear to fix it.  Thanks!

[pizmogames2]

Replacing adb, aapt, and dx.jar from latest sdk worked for me on Mac OSX, FB 4.6, Google/Asus Nexus 7 tablet running Jellybean 4.2.2.

[Defocalise]

Worked for me in FB 4.5 using the 3.4 SDK.

Nice one thank you!

[Gamonama]

On Mac, Flash Builder 4.6

the destination folder to copy aapt, adb and dx.jar files is located at

/Applications/Adobe Flash Builder 4.6/sdks/4.6.0/lib/android/bin

The solution worked for me by downloading the latest sdk bundle from android and copying the above mentioned files to the destination folder. So thanks guys for all the help.

Cheers !!!!

Ok. I'm running into the same exact problem. I cannot get it to work with the fix above.

I'm running windows 7, Flash Builder 4.7, and did a fresh install of the Android SDK. I'm trying to use my Samsung Galaxy 3 as the debugging device. It has Android 4.3 as well as Air installed. Debugging is on and drivers installed.

I copied the following files.

From C:\Program Files (x86)\Android\android-sdk\platform-tools     adb.exe, AdbWinApi.dll, AdbWinUsbApi.dll    

From C:\Program Files (x86)\Android\android-sdk\build-tools\19.0.1     aapt.exe

From C:\Program Files (x86)\Android\android-sdk\build-tools\19.0.1\lib     dx.jar

To C:\Program Files\Adobe\Adobe Flash Builder 4.7 (64 Bit)\eclipse\plugins\com.adobe.flash.compiler_4.7.0.349722\AIRSDK\lib\android\bin

I still get the error below. Any other suggestions would be REALLY appreciated. This is really a pain in the rump. Thanks.

[ethierse]

@cporterAlleni

1- Did you updated android-sdk before to copy ?

2- if you tape : $ C:\Program Files\Adobe\Adobe Flash Builder 4.7 (64 Bit)\eclipse\plugins\com.adobe.flash.compiler_4.7.0.349722\AIRSDK\lib \android\bin\adb.exe version 

What number version do you get?

3- if you tape : $ C:\Program Files\Adobe\Adobe Flash Builder 4.7 (64 Bit)\eclipse\plugins\com.adobe.flash.compiler_4.7.0.349722\AIRSDK\lib \android\bin\adb.exe devices

Do you get the id of the conntected device ?

4-About the Samsung Galaxy 3, did you install the proper driver to connect with adb ? Did you follow these instructions at

http://help.adobe.com/en_US/flex/mobileapps/WSa8161994b114d624-33657d5912b7ab2d73b-7fdf.html

1. Plug the device into a USB port of your computer. Windows informs you that it cannot find the driver.
2. Using the Windows Device Manager, open the Details tab of the device properties.
3. Select the Hardware IDs property to view the hardware ID.
4. etc...

I tried others solutions posted but didn't worked .

Hi hpmad‌,

I hope you have enabled developer mode in your device and also allowed USB debugging for the computer (the dialog that appears when device is connected to the computer)

You can also try to install latest USB driver for the phone you are using.
