I previously developed on Eclipse and just migrated to Android Studio.
Everything works fine, it's better and faster.
I work on real device, and Android Studio recognizes it without issue.
But when I disconnect and reconnect my device, it doesn't recognize my device anymore, I have to exit and restart Android Studio.
I can't find a way to "Reset adb" like Eclipse Feature.
Can ADB be restarted from within Android Studio? If so, how?
What I usually do when I get this error is restarting the adb server by typing in the command into Terminal:
adb kill-server
adb start-server
However this can be achieved in Android Studio. Clicking the Monitor button you can launch the same program you have referenced from Eclipse.
If you do not see this you may need to update your Platform Tools from the SDK Manager button.
Apart from the above working answer, the ADB can also be restarted during the restart of Android Studio ( File > Invalidate Cache / Restart > Just Restart ).
ADB is down for a reason, therefore a clean restart of Android Studio is suggested.
that did trick for me thanks. resetting adb on android studio fixed my issue of ADB not responding. If you'd like to retry, then please manually kill "adb.exe" and click 'Restart'. spent 2 days trying look for solution to this

I'm working on a project for my Android class using the latest version of Android Studio (3.4.1) and my app isn't working right. I can't see what's going wrong because nothing shows up in the Logcat.
I'm running my app on a physical phone since Android Studio doesn't like AMD. I have "Show only selected application" selected and it shows my phone is connected. I tried restarting Logcat, but that didn't do anything.
screenshot to show my issue
Just try ,Invalidate and Restart Android Studio or Restart Android Studio.
Keep the device connected. Open terminal from below. Type following command to kill and start adb.
adb kill-server && sudo adb start-server
If the command doesn't work, you will need to fire it from /sdk/platform tools/
I'm creating an application in android studio but I am um able test it on the virtual emulator because the adb process won't start. It's giving this error.
I tried manually starting adb and all other things but this happens.
I tried reinstalling android studio and platform tools. I downloaded a separate adb and ran "adb start-server"/"kill server".
It just doesn't seem to work. So i constantly have to build the entire thing and generate apk to run it. Please help me guys!!!
Also regarding the virtual emulator i have intel haxm installed if that information was necessary.
It's may be because your emulator adb not allow the android studio to run on it and android studio try to stop and re-run but this process fail.
Me also the same problem. So i always follows this step and it's work for me.
1. Open android studio.
2. Try to run your app without opening your emulator(It will start your adb).
3. Then open your emulator and run your app.
It's working for me. May solve your problem.
adb server didnt ack. This issue will resolve ussually when you kill all instances of adb.exe and restart server again.
Open Task manager and kill all adb instances and start server again.
Try the following:
Close Studio.
End adb.exe process in taskmanager.
Issue kill and
Run adb kill-server
Run adb devices
Then start the emulator and try adb devices again. This should list your emulator-device.
Run you apk in studio.
If your are using Genymotion,try to link your Android Studio 's SDK to Genymotion Android SDK Path.Then try to type with adb devices, I hope this will help for you.
I am having a slight issue when trying to debug and android app via usb to external device. I keep getting the error "Warning: debug info can be unavailable. Please close other application using ADB: Monitor, DDMS, Eclipse
Restart ADB integration and try again
Waiting for process:"
I have tried stopping adb.exe in task manager , closing android studio and restarting , taking out the cable and putting it back and going to tools => android uncheck adb intergration then recheck it . All to no avail
This is a problem of ADB connections as sometimes ADB cache a dead connection on your real/virtual device and due to which the port is busy and u cannot connect to it.
The simplest solution to this is RESTART your ANDROID phone that's it.
What worked for me was to disable and re-enable USB debugging on the device.
Following steps resolved this issue to me:
Disconnect the device.
Restart android studio.
Run the project.
Simply go to your Android phone developer settings, disable USB debugging, delete all authorizations for USB debugging and turn the debugging on again.
First make sure you close any application use ADB , DDMS
like if you open Eclipse with android studio
Second restart your ADB from terminal
adb kill-server
adb start-server
The issue occurs when I open the Android Studio and IDEA together.
Restart the Android Studio does NOT fix the issue
Re-plugin the cable either does NOT fix the issue
Restart the Mac either does NOT fix the issue
Restart the ADB from terminal FIX the issue
adb kill-server
adb start-server
In this way, you do not need to close the IDEA.

Restart the Android device fix the issue.
This problem sometimes occur when Android Studio is opened with another IntelliJ Editor. Just close the other IntelliJ Editor.
Open USB preferences in your device. Like the image below.
Click another option. (eg:File Transfer)
Click the no data transfer.
If it doesn't work,please try again.
The operations on the android devices are similar.
this may happen when you created two instances of android studio, or else you are using same device in multiple ADB programs, so simply disconnect you device and then open your desired android studio instance and then connect again. now it will work fine.
i also use same method and every time it works.
IntelliJ IDEA (Ultimate, probably also Community) comes with Android plugin. If IntelliJ is started and any project is open and has been compiled (even without any Android code-base) then IntelliJ (apparently) steals the adb-connection from Android Studio. Either close IntelliJ or disable the Android plugin in IntelliJ.
If IntelliJ is open with android plugin, rebooting phone, killing adb etc. are only sporadic and short-time fixes of the problem as IntelliJ steals the adb connection again.
I resolved this issue by changing the Use USB for settings
Go to setting select transfer settings in my case MIDI was selected.
Go to Airplane mode ON and OFF , After that everything back to normal.
In my case, I had my device connected both via WiFi (with adb tcpip) and USB cable. Disconnecting the USB cable solved the issue.
Quite awkward issue, I think none of the solutions mentioned above worked for me.
Ultimately, I had to invalidate caches and restart.
File -> Invalidate caches... -> Select both options -> Invalidate and restart
For me was Eclipse using DDMS and conflicting with Android Studio, I wasn't using, so I just uninstall it.
If is your case, go to Eclipse > Help > About Eclipse IDE > Installation Details > Select DDMS and Uninstall..
At times ADB caches a dead connection on device(real / virtual) due to which the port is busy and it is unable to establish a connection.
You can try different ways:
You can kill and restart the server:
adb kill-server
adb start-server
2). Try disconnecting the device(phone) and reconnecting it.
3). Restart your device (phone).
Slightly different answer, but I'm including it for completeness.
For me Android Studio had frozen as well with the spinning beach ball of death.
I rebooted the emulator (by having it emulate a power-off/restart cycle)
Killed Android Studio (on a Mac by using ⌘⌥esc)
Restarted Android Studio.
After that everything was back to normal.
if you open two Android Studio at the same time (android studio preview),Will be like this
A possible temporary work around that may work prove useful for progress sake when intending to debug is to run the app in android studio , then immediately click on run => attach to debugger
When I run my app from AndroidStudio 0.4.3 using Run I see Choose Device which has two sections choose a running device or Launch Emulator. I don't have a running emulator at the moment so I click the ... to launch AVD manager and start an emulator. At this point I see that under choose a running device the emulator I just launched shows up but its listed as offline.
In the past the offline status went away when the emulator was fully up and running. However, now I've noticed that when the emulator is launched fully, it no longer appears in choose a running device.
I feel like I'm always playing cat and mouse game with android studio picking up the emulator. Is there a better way to do this? Am I missing something?
Disable and then Enable ADB Integration
In Android Studio go to
Menu -> Tools
Android
Enable ADB Integration (should be checked, click to remove check)
Enable ADB Integration (should not be checked, click to add check)
Run your app again. Emulator that was previously missing from Run dialog should be available to be selected upon which to run your app.
Try to kill the adb server and restart it.
Locate your adb binary (linux/osx) or adb.exe (windows) and do:
adb kill-server
adb start-server
this should fix your problem
Even if your problem still not solved then Restart emulator.
Wipe Data and restarting emulator helped me, hope this helps to someone.
inside AVD manager, select your virtual devices, then 1 stop, 2 wipe user data, 3 cold reboot, works for me.
On Windows, running Android Studio with administrator permissions can help (in addition to restarting adb server).
Unchecking the "Enable ADB " worked for me
In Android Studio Arctic Fox (2020.3.1) it helped me to cold boot the device.
add -port 5037 on ../[some_emulator]/emu-launch-params.txt file & try again...

I'm using eclipse Kepler, and ADT bundle for android development and when I run an android project the emulator began to disconnect. I tried again after restarting the Eclipse IED and even I reboot my machine. But it's stay the same. Can someone help me with some useful advice. Thank you!!!
The communication with the emulator or your Android device might have problems. This communication is handled by the Android Debug Bridge (adb).
Eclipse allows you to reset the adb in case this causes problems. Select therefore the DDMS perspective via Window → Open Perspective → Other... → DDMS
To restart the adb, select the "Reset adb" in the Device View.

Open your terminal or Command Prompt of what OS you use , then use the following command
adb kill-server
Then type
adb start-server
finally
adb devices
You should see the attached devices and eclipse will find it. Make sure adb path has been added to your system path before you apply these commands.
I also face with the same issue, Samantha Withanage. When I run the project on the emulator, and face with the same issue, I re-run the project (without closing/restarting anything viz. Emulator, Eclipse or the machine). Then it works fine.
Try this scenario from your end as well. Hope it works for you as well.
