adb connection not available, or was terminated - Android

First I have updated to Marshmallow and then Created AVD with Google API.
Once created it shows as
then after deletion when i run project
then my error getting
When i Run the APP (Shift+F10)
It shows the error as
at App tab :-
adb connection not available, or was terminated.
At emulator tab:-
D:\ADTSDK\adt-bundle-windows-x86_64-20140702\sdk\tools\emulator.exe -netdelay none -netspeed full -avd Nexus_One_API_23
emulator: WARNING: Increasing RAM size to 1GB
qemu: could not open disk image C:\Users\xxx\.android\avd\Nexus_One_API_23.avd/sdcard.img: Operation not permitted
I m unable to test my project with emulator and have searched on SO
I tried this also :
at cmd prompt :
adb kill-server & then
adb start-server
Any solution to work with Android emulator surely appreciated.

Setting the android:targetSdkVersion to 23 did the trick for me. I was launching Android N preview (API23, same as Marshmallow), had the same error (adb connection not available, or was terminated).
Sometimes, I still get the error (e.g. if I opened Android Studio just now).
I open the Android Monitor tab , wait for logs from the emulator to start appearing, and rerun my app

fail to start android emulator after update sdk to 23.0.5

I cannot start my emulator after update sdk to 23.0.5 with following errors on windows.
Can anyone help? thank you

Start it from the command line:

Same here, it seems to be related to http proxy (on command line -http-proxy, or as environment variable http_proxy), if I don't use http proxy it works.

Adding "-http-proxy none" (without quotes) in Run configuration also fixes this issue as shown in image attached.

Related to this thread: Android emulator with proxy settings - Error FATAL:.//android/base/sockets/ Check failed: isValidFd(fd). fd 1404 max1024
It still doesn't work. Please star this bug report so we can get it fixed - I already suggested to modify FD_SETSIZE from winsock.h to higer value e.g. 2048 as it doesn't change windows socket implementation as per microsoft's documentation:
// Default FD_SETSIZE is 64 which is not enough for us.
# define FD_SETSIZE 1024
https://code.google.com/p/android/issues/detail?id=102361

Found another solution:
You can now use the new Android Emulator 2.0 Beta that has the defect fix.
The defect workarounds (-no-audio -http-proxy none) didnt work for me.
Get Android Emulator 2.0 Beta:
By downloading the new "Android SDK tools" version 25.x.x .
Full instructions can be found here.

I hit this today, and deactivating proxy (or audio, as suggested in another recent question) made no difference. It affected all my AVDs. When I first opened the AVD Manager I was also getting the following error:
Android SDK Content Loader
parseSdkContent failed
Could not initialize class android.graphics.Typeface
Following the advice from parseSdkContent failed Could not initialize class android.graphics.Typeface to:
shutdown eclipse
delete the .android directory (and all contents) in my home directory (e.g. C:\Users\<your user name> on Windows 7)
restart Eclipse
worked a treat for me.

How to solve this error?

First make sure you are running Android Studio version above 0.3.2 because there was some issue reported regarding the same in AS 0.3.2 . If it is not you can update it from Help >Check for update.
If you are already running AS above 0.3.2 :
Seems like issue is with your emulator not with Android Studio. It may happen that you are trying to install application before even the emulator started properly.
Wait till the home screen appears in the emulator before trying to install any application.
Also try to install any apk in Emulator from command line
Steps to install
Go to $Android_SDK_DIR\platform-tools, right click there keeping
shift key pressed and Chose "Open Command Window here".
Run command adb devices to make sure yout emulator is running
properly. It will show all your running emulators.
Now if emulators are showing properly, type the command adb install
YOUR_FULL_APK_PATH , YOUR_FULL_APK_PATH is of any .apk file path in
your system.
Please update if this works fine.

The most common cause of this error is simple: You have to manually unlock your Android Virtual Device by swiping the “lock” icon on the screen. Security measures prevent the emulator from letting you connect the debugger before doing this.
The problem is resolved:
In Android Studio
Start run/debug
if you see the message
Do not closed the AVD, just click on run/debug again, the Application will be running when you unlock the application.

The same problem but different solution, I modified my Virtual Device, I changed Memory option and Internal Storage, and it works fine.
RAM:512 , VM HEap: 192, Internal Storage=200, SD Card Size: 200 for Device Nexus 4 android 4.2.2.

In my case this error was caused by SELinux. I got to set SELinux to permissive.
adb shell su 0 setenforce 0

I had this issue, but I found that simply killing the emulator and restarting it worked. There seems to be some sort of race condition where the emulator has not initialized before Android Studio tries to launch the apk and so you get the package error.

I had this too, and using this config worked for me :
Device: Nexus One
Target: Android 4.2.2 -api level 17
CPU/ABI: ARM (armeabi-v7a)
Keyboard: Hardware keyboard present
Memory Options:
RAM: 512
VM Heap: 192
Iternal Storage: 200
SD Card:
Size:200

This Is Worked for me
1)Close Solution.
2)Close Emulator.
3)Run Emulator and Wait till it launch completely and shows Home Screen.
4)After that only Open Solution And Clean,Rebuild and Try to deploy Application.

The same happened to me right now. I don't know if there is another but for me the following worked:
Opened AVD (Android Virtual Device) Manager
Started virtual device
Hit the Run button again (that one at status bar)
Explanation: The problem happened because of timeout. Once device had started, the Android Studio could comunicate with him. (v 0.5.3)

Remove this emulator (in the AVD)
Install this emulator (in the AVD) :)

OSX: Android Emulator Crashes

I've just reinstalled eclipse indigo (32bit) and the latest Android SDK. The Android Emulator crashes immediately after it is launched.
Here are my steps:
Create a new Adroid project. Target is Android 4.0, SDK 14.
Press the Run button in Eclipse.
See the Emulator launch and crash about 2 seconds later
Output of crash window:
Exception Type: EXC_BAD_ACCESS (SIGBUS)
Exception Codes: KERN_PROTECTION_FAILURE at 0x0000000000000000
Crashed Thread: 0 Dispatch queue: com.apple.main-thread
The Eclipse console complains about the following:
Warning once: This application, or a library it uses, is using NSQuickDrawView,
which has been deprecated. Apps should cease use of QuickDraw and move to Quartz.
goldfish_fb_load: framebuffer dimensions mismatch
savevm: unable to load section goldfish_fb
emulator-5554 disconnected!
Cancelling 'com.sparky1.HelloAnrdroidActivity activity launch'!
Any thoughts about how to get emulator to behave?

This has already been reported as a Bug: http://code.google.com/p/android/issues/detail?id=724
There are some workarounds presented in this post, too. But at this point, there seams to be no actual fix.

It looks like this happens when an external monitor is connected. Try disconnecting your external monitor and then start emulator. You can attach it back after the emulator starts.

I've seen this problem too. I've found that running emulator from command line and disabling snapshots help a lot.
I'm running:
$ emulator -no-snapshot-load #avd

If disable snapshot when create device, ok. Do not enable snapshot.
If enable snapshot, it's ok to check "save to snapshot" when launch device.
But check "launch from snapshot" is not ok. If already save snapshot, it will cause emulator-arm crash.
After emulator-arm crash by "launch from snapshot", disable snapshot with AVD manager does not work. But run config > target > additional command line option(-no-snapshot-load) works.

I had all these crashes as well and found this in my crash logs:
Thread 0 Crashed:: Dispatch queue: com.apple.main-thread

After spending only a couple of hours :-( on the net I found a tip to remove
/Library/Quicktime/CamCamX5.component
After that no more crashes :-)

An alternative is to switch to using AndroVM in Virtual Box which is an X86 Android image. The big advantage is that it is lightning fast compared to the ARM one. It boots in 2-3 secs. The downside is that you have to manually do the ADB connection and the capturing of the mouse by virtual box is a pain. Not all applications will run on the x86 as well.
To use it you have to configure the first Ethernet adapter as Host Only, run the androVM configuration utility to get the emulator's IP address, then use adb connect ip-address
Another tip is that if the screen times out you need to hit F1 to wake it up.

Issue with 'Hello Android' tutorial

I am brand new to Eclipse and Android, but somewhat familiar with Java. That having been said, I tried to follow the 'Hello Android' tutorial from the developer site using the latest Eclipse (Galieo) and the 2.1 Android SDK, I am on a Macintosh running Snow Leopard (OS X 10.6). I have a default virtual device (though my target is actually for phones like my own HTC Incredible which has the snapdragon processor and of course all the latest accoutrement in smart phones).
Everything seemed to go okay until I went to RUN>RUN and then selected 'Android Application'. My computer spins its wheels for a while and then I see two errors. I have pasted the output from Eclipse below:

and move to Quartz.
Segmentation fault
iainnitro-Mac:tools iainnitro$
yields a segmentation fault(as noted above from the terminal output). So the emulator is dying on its own before anything can be shown.
I have tried restarting the ADB processes.
The actual code is line by line from the tutorial and I have never been able to get to the XML part yet.
I am not sure what is wrong with my environment setup or if it is just an incompatibility with Snow Leopard? I would REALLY appreciate any help in resolving this as I am very interested in developing on this platform.
Thank-you,

No direct experience, but this seems to be a recurrent issue:
This thread suggests:
You haven't let the emulator boot all the way up. Start it then wait until you see a desktop, just like on a real phone.
This one mentions (I suspect point 1. is not a concern for you):
Get more RAM. I was running on 256 MB (which I believe is below minimum requirements), just upgraded today to 1024 MB (long time coming), application now starts fine. Although I still do see some error messages in the emulator, they don't seem to actually do anything.
Install from command line. This is a bit laborius, but you can launch an emulator from the command line (assuming <android sdk path>\tools is added to your PATH variable) just type emulator, then browse to the location of your_app_here.apk, and execute
adb install your_app_here.apk
If you launch the emulator from Eclipse, execute adb kill-service and then adb start-service first (or kill-server / start-server. not sure the exact commands). Then your app will be installed on the emulator.
Also (a bit old but might still be relevant)
Maybe the emulator is running so slow, and the adb server, or another component like "DDMS" is a little "desperate" because seems it's waiting to the emulator to iniatialize the some HOME aplication.
But the emulator is running slow, the console in Eclipse send a message: emulator-5554
disconnected! Cancelling 'com.android.hello.HelloAndroid' launch!; and the emulator continues running normally and boot it's system, but don't run application that I build.
So for that problem I run program, and when the emulator is opened, I go back to eclipse in DDMS Perspective and in the Device tab y press a button "restart adb server" before the console shows me the message of "emulator-5554 disconnected!".
I do it several times until the emulator finally boot the OS.
After booted the OS on the emulator, eclipse don't send that disconnect error, and "sends" the app that I've built, also the console shows messages about this.
Then finally appears on the mobile "Hello, Android".

There has been a discussion on this with two proposed solutions

FYI - I had to change a line in the Hello Android example to read
this.setContentView(tv); in order for it to work. As mentioned above, the deprecation
warning shouldn't affect the functionality of the emulator.
Comment 18 by mfrony, Jan 14, 2010
I had the same problem when I ran the Hello Android example. The way I solved it and
could run my first Android code was by changing the Project Build Target from 1.1 to 1.5.

This seems to be a timing issue. For some reason Eclipse attempts to load the application on to the emulator before it is "ready". I'm not sure why this occurs but I did find a work around: just start the emulator from the command line before you run the application.
Start clean by closing Eclipse (maybe the OP didn't exit Eclipse before he tried to run via the command line?)
Start the emulator via Terminal by navigating to the android-sdk-mac_86/tools directory and typing:
./emulator -avd my_avd
Open Eclipse and attempt to run the tutorial again using the same steps as before
A dialog box should open asking whether you would like to start a new AVD or use the one that is already running--choose to use the one that is already running.

what i did was to move the circle that appears when the AVD launches to the unlock position, and there it was 'Hello, Android'!

I had this same problem when I tried to run the emulator using a 4.0 AVD. It used to crash at the bootup screen and show 'Segmentation fault' in the console. I was able to fix it by increasing the SD card size of the AVD to 1GB from 32MB.

For whatever reason, I stopped getting the segmentation fault when I added:
this.setContentView(tv);
the 'this' seemingly solved the issue. The seg fault happens if you try to run the emulator without any .apk file I assume. (I was getting that from the command line as well). I hope the tutorial will be updated.
