I've played with the AVD Manager by deleting and adding devices and finally i get the error below. Something that did not do it before...

Emulator works in Android Studio but not VS Code

I'm running emulated devices in android studio just fine, but when i try running it in VS Code, I'm get this error: "Failed to launch Pixel 2 API 27: Error: Emulator didn't connect within 60 seconds"
saw some videos and guides, but they all say to reinstall the emulator or wipe the emulated device, which doesn't help.
what could be the problem?
trying to use this for a flutter project that i'm trying to create, and it kind hurts testing.
I found your problem is the same as this
Steps:
Open Android Studio Tools -> AVD Manager Virtual Device -> Actions (Refer Image) Click On Stop Now Start Emulator Now it's working fine :)
or please visit that link Failed to launch`
Apparently, the only way to run the emulator, is to run the device in Android studio, and then run the app in visual code.

Failure [INSTALL_FAILED_INSUFFICIENT_STORAGE] when attempting to run flutter app on android emulator on MacOS

I have been dealing with a very persistent error when attempting to run a flutter app on an Android Emulator (Android Virtual Device launched through Android Studio) through VS Code. Here is a screenshot of the errors:
I have attempted to wipe data & cold brew both my emulators & reopen the application folder to no avail. I am beginning to feel hopeless. If anyone can help me at all, I would really appreciate that. Thank you in advance :)
PS: here is how the emulator looks
if you wiped the emulator's data and it is still showing the error, try to increase your emulator's space,
Tools
AVD Manager
Locate the emulator you want to increase space, click the drop down
Edit
Show advanced settings
Edit the Internal storage
Restart the emulator if it's running
NOTE: Newer android studio versions do not have the Edit option inside the dropdown, it was moved next to the dropdown menu (The edit icon)
I had also faced same error on windows:
Failure [INSTALL_FAILED_INSUFFICIENT_STORAGE] Error launching application on Android SDK built for x86.
What I done was, just wiping out the data of emulator from android studio and it worked.
here there is an option of wipe out

Error: Errors were encountered while preparing your device for development. Please check the Devices and Simulators Window. (code -1)

i want to run my flutter app on my iphone from android studio, but Android studio doesn't read my phone on the devices tab while I clearly see it active on my mac.
while running flutter doctor I get this message:
Error: Errors were encountered while preparing your device for
development. Please check the Devices and Simulators Window. (code -1)
and I have restarted my phone, the issue still persists, what do i do?
Follow the steps in this answer
And try always flutter devices to see if your device was detected by flutter
I had the same problem after an iOS update.
The solution is:
On your iPhone, go to Settings > Privacy & Security > Developer Mode and switch it on.
Your device will restart and after the restart it will ask you again if you want to switch on the developer mode, hit yes and the android studio should recognize your iPhone.
Hope this helps.

Android Emulator starts, but it doesn't run android system

I try to run my app in android emulator. From the begining, everythigs works fine. I create new device in Android Vrtual Device Manager, then i run the device. After a while i can see an emulator with mobile skin - that's all, nothing else happens. The device has black screen and in the Android Monitor I see this:
screen from Android Monitor
When i try to run my app I recive this:
screen from selecting deployment
When I try to run app from this window, somethig is going to happen. I have to wait long long time but finally, android is started on the device but meanwhile i recive error "Session 'app':Error Instaling APK. Sometimes app will run, sometimes not, but everything works very very slow. When i run app directly (without running device from AVD Manager), app is bulided and then i see a process "Waiting fro target device to come online", emulator runs but with black screen.
I have no idea what to do now. I reinstaled Android Studio twice - always the same result.
I have to add that a few days ago everythings works perfect - very fast and without problems. Recently I was installing Ubuntu on a new partition, I've done some changes in widows driver manager. Maybe this is a reason?
What I should do now? Thanks in advance
