Flutter: 2.2.3 - How to solve the error: Error connecting to the service protocol: failed to connect to http://127.0.0.1:XYZ

When I create a clean flutter project(flutter create proj_name) Then I try run it in debug mode from vs-code on a real device android 5.1.1 and it starts and works fine for the first time, but if i stop application and run it in debug mode again the following message like this results
What helps to run in debug mode the application is restarting the real smartphone so it will work until you stop the application and try to run in debug mode again.
Does anyone have any suggestions how I can solve this?
The error points out that it has issues connecting to the Android emulator. Checking the flutter doctor logs, the emulator doesn't seem to appear. Try restarting the emulator using cold boot. Open the Android Device Manager and click on Cold Boot Now on the emulated device. Then run flutter doctor --verbose to check if the emulator can now be seen in the list of connected devices.

Flutter showing 'No Devices' even the devices are started

Flutter run is not working when I started the emulator and the emulator seems to work fine. Where's the problem currently running in UBUNTU

React native Android Project Not starting in emulator

i just created a react native project on windows, using expo. After Creating the project i ran npm start and then expo start the next logical thing to do is to press the a button which will launch, the project on the android virtual device, but instead it gave me this error Couldn't start project on Android: Error running adb: Error running app. Error: Activity not started, unable to resolve Intent { act=android.intent.action.VIEW dat=exp://192.168.43.148:19000 flg=0x10000000 }
when i tried running it on my android phone with the expo android app it ran smoothly, i don't know what to do please help thanks
I had the same problem and I got it fixed as follows:
Go to SDK Manager in Android studio > SDK Tools and check whether there is any update for Android SDK Build-Tools. If there is any, please make sure you update it.
Close any Android virtual device currently running and then go to Android Studio Virtual Device Manager and wipe the data of your Android virtual device.
Make sure you have enough internal storage allocated for your Android virtual device to install apps.
Check whether Android Debug Bridge utility is installed in your device. If not please install it. To install in mac, I used the below command (Assuming that you have HomeBrew installed in your mac device):
brew install android-platform-tools
Start your Android virtual device ( This step should be done before running the expo development server)
In the Developer options menu of your Android virtual device, make sure USB debugging option is enabled.
Finally, try running the development server by expo start and press on the button to run on your Android emulator.

How to prevent launch Ionic app on emulator

How to prevent run app on windows emulator? I want to run app on real device that conected to my computer.

I have read these questions, But I didn't got the answer!
Why not work Ionic app testing on android real device?
Ionic run android does not run app on device
ionic run android - configurations not running app on device
As a complement to #OClyde answer, you could try :
adb kill-server
adb start-server
To have infos about these commands :
adb --help
Nb : Sometimes, for a reason i do not know, the connection between my phone and the computer break. Running this fixes it.
To make sure that your app is not installed to an emulator but to your device, take the following steps:
Open up your console and run adb devices. This should give you a list of all devices available (real devices as well as running emulators) to the Android Debug Bridge. If the adb command is not recognized check that you have installed the Android SDK correctly and that you've set all the necessary environment variables accordingly.
The adb devices command might give you output similar to this:
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
This indicates that the ADB wasn't ready before, so in this case just try to un- and replug your device and run adb devices again to see if the device is listed afterwards.
If your device is still not showing, check that USB Debugging is enabled on your device. Therefore you first have to enable developer settings, which you can do by tapping the build number (Settings => About Phone) 7 times (no, that's not a joke ;) ). After that, you'll have the developer options in your settings menu. Open these and check "USB Debugging"
If still your device isn't recognized by the ADB, change the USB connection mode. You can either do this in the developer options as well or tap the notification shown when the phone is connected to your PC. Try MTP as well as PTP, on of those should do the job.
After these steps, it should be nearly impossible that the device is still not recognized by your PC. As soon as there is a phone available, Ionic will install the app on the phone automatically instead of launching an emulator.
