this error: emulator-5554 disconnected! Cancelling com.something activity launch' - eclipse

Sometimes this error occurs:
emulator-5554 disconnected! Cancelling ... activity launch'!
Please tell me what to do.

I had also faced this problem in past and one of below solutions may solve your problem.
first solution
Open Android Virtual Device Manager select the AVD you use for your
app. Press the start button and wait for a new form to show up called
(Launch Options). Check the box "Wipe user data" and hit "Launch"
button.
second solution
go to task manager and process
adb.exe 32* and end this process
then restart your eclipse.

you have to reset your adb. go to Eclipse IDE-->window--> Show Views --> device--> view menu --> reset adb

In my case it seems that AVD file was corrupted. I just created new AVD and it worked.

Android Studio Reload not performed Flutter

I have an issue when I try to save any modifications on a new project, the hot reload doesn t work on save, because he has an issue that I can t find
I need to mention that I do not modified anything in the project, just started 2 hours ago and searched for the solution
I just tried to modify the title and nothing more first
In android Studio on the top left corner choose File -> Invalidate Caches...
Then you will see a modal
check both option and press the "Invalidate and Restart" button.
When the Android studio starts again, Re-run your application and check if the hot-reload works properly.
That worked for me.
There is a banner on top that says you haven't run pub get. You can press the button on that banner to run the command (Get dependencies).
This is likely because you changed your pubspec.yaml file.
Another thing you can try is to stop and restart, this is sometimes necessary. If this also doesn't work, try to clean using the command flutter clean and/or restart Android Studio

Android Studio console not showing logs of application running

I am running application on real android device. I want to view logs in console to figure out errors and APIs responses. But I don't know sometimes it stop showing logs in console.
Here is the screenshot of my console.
I is not showing anything after this even though I am printing in logcat.
Can anyone tell me what is the issue and how to resolve.
Try restarting your logcat and then rerun you application. ( If your logcat window tab does not show up in Android Studio you can follow this: Logcat tab missing from debug window in Android Studio )
You can simply follow my steps down below.
Step - 1
Goto File --> Invalidate Caches
Step - 2
Click to "Invalidate and Restart"
I hope this might solve your problem.
Thank you and Happy coding.

Flutter cannot connect to emulator in VSCode. Waiting for a connection from Flutter

I can see the device list on VSCode in Windows.
And I can select any one.
And the emulator is opening.
But I can see a single message. "Waiting for a connection from Flutter.."
Application does not open.
It doesn't get any errors either. Waiting like this.
Make sure that your API level you're running your device on is the
same as what you have installed on Android Studio.
1.1 Click on the SDK Manager button around the top right corner of AS (The icon is a box with a down arrow next to it).
1.2 Choose the same API level as your device, (When I didn't do this I had a partial install and it took some time to compile), then
click apply and wait for it to install.
We're going to run the project to our avd or mobile device from the directory of ourproject.
2.1 Open up the Command Prompt (preferably as Admin), and chage the directoy to where your project is, the command should look something
like this:
cd Documents/flutterprojects/yourflutterproject.
2.2 Finally type the command flutter run.
Restart the Emulator by holding the power Button and Selecting restart and then try again.
if that failed to work, simply restart your computer.

Emulator: ERROR: unexpected qemud char. channel close

Whenever I try to launch an Android app it will cause this error:
emulator-5554 disconnected! Cancelling
'com.hellos.ArithmaticCalculatorActivity activity launch'!
that is a known emulator bug. Do you happen to be running Ubuntu?
Try deleting and recreating your AVD. If you're still having problems, try the following:
Try launching in several ways: by starting the AVD first from your
list of AVDs, by right-clicking the project in your workspace, etc.
Click on Window-->Show View-->Other-->Devies, and click on the
launched device, highlighting it. There is a known issue that
sometimes robs your AVD of focus unless you do this.

Do you see this every time you launch your test?
This thread mentions:
For the 8530 simulator just try it again.
I get that message sometimes when I am running too many apps/low memory (I do a lot)/just started Eclipse/etc.
Often if I run it a second, sometimes third time it works and continues to work after that.
