I've been learning and working with Flutter for a few weeks now. I used some of the Android Emulators that Android Studio provides and it was doing fine.
But recently, I opened an emulator to run a Flutter project while a memory card was connected with my laptop, and suddenly a notification was shown in the emulator of detecting a SD card and with that another notification was shown saying:
Serial console enabled
Performance is impacted. To disable, check bootloader
The notification is not clickable, and neither it removes even after I deleted all the emulators that I installed using the AVD manager. And as the notification says, it really is impacting the performance of the emulators. Before it showed up, I could see the changes in the app immediately after making changes to the code and saving it, but now, it takes so much time to show the changes even if I use hot reload or hot restart.
Is there any way to get rid of this? How can I disable the Serial console?
Enter engineer mode (*#801#) and disable the option that says serial. Google it how to access engineer mode if the code doesn't work for you.

Is that possible disable device switch in Visual Studio Code when develop flutter ?
What's my condition:
I have simulator opened, and debug for a while, code for a while.
Then I need to plugin my phone to charge power of phone. But vscode too clever to switch the device to my phone automatic.
And then when I debug, I always found why it's build slow now? And found out that it's debugging on my phone now...
Any idea to solve this ?
PS: I didn't always have usb power for my phone beside my computer.
It seems that it's possible to disable that (default is on). Go to User Settings -> Extensions -> Dart & Flutter
You can also select device with this action:
I want to get performance analytics of my game using Profiler so I have exported build with Autoconnect Profile setting enabled.
After this process build installed within an Android device but it can't able to run the game, it just displaying black screen nothing else. Profiler can't able to connect with the connected Android device, I was getting this kind of list within Unity profiler:
Now android device showing just black screen and profiler not moving ahead, it just remains connected with Editor only.
I have tried to connect and disconnect my Android device multiple time but nothing changed in this. Please give me some suggestion into this so I can start my debugging process.
I have already gone through this post:
Profiler window
I believe you need to build in DevelopmentBuild enabled to be able to attatch profiler
Out of blue the android emulator with google play services API 27 did not unlock its screen. After I insert the password on Mac Mojave I get back the lock screen instead of accessing to the device. I try to swipe up but does not work.
I tried without success to uninstall the emulator, to wipe data, as I found in this other post My Emulator won't unlock. Is this a known bug? I cannot find official google list where people complain about this issue, so I am wondering what I did wrong. I have also tried to activate the camera, but does not work as suggested in the above mentioned post.
I expect that when I insert the just password the emulator is unlocked, the just password is 0000 and I do not get a wrong pin message, but a black screen for 800 milliseconds and then the lock screen with some notification.
Can you try wiping the data and reboot. Or try creating a new emulator with Nexus5X with Android28 or other.
When you try to start the emulator from Android Studio, in the AVD manager, select the drop down and Wipe Data.
i'm new into programming for android. And i have few problems with connecting and debugging my eclipse project on android device - which is my phone Samsung Galaxy SIII. According to this link I tried to launch my app on my phone. Saddly when i press run button it tells me that there's no android device connected. And as you may know im not that dumm to not plug it into my computer. Additionally i have USB Debug mode ticked in options. My PC recognises it as "SAMSUNG Android ADB Device".
Some of you might say that i should start using emulator to have better view how this app will work on other phones/versions of android/etc. Thing is that my PC is quite old, and running an emulator makes it respond so slowly that it's nearly impossible to do anything on this emulated device. Plus... im quite sure that i wont publish this app on play store so i dont need to know if it will work on other devices. I just want to make a weather widget for me since stock one that uses accuweather.com tends to fail weather forecast for my country (like it says heavy rain on sunny day).
So here are the things that i have done so far to try to launch:
1. Uninstalled device and set some new drivers that should have helped me - saddly not ;]
2. Tried launching it via command line
3. I found somewhere on the Internet that it is possible to connect and test your app via WiFi using tcpip over 5555 port... saddly it failed too.
Any ideas what else should i try to make it work?
Solution: Why is Eclipse's Android Device Chooser not showing my Android device?
THis is getting annoying. My device shows up in eclipse on all
platforms.. Except when I am on my Ubuntu laptop.. when I "run
configurations" with it set to Manual.. I can see that there is an
Emmulator running that I can Install the App to.
Problem is, the Emulator is a pile of horse crap when it comes to
testing on real devices like my Samsung Captivate.
When the Captivate is plugged in via USB.. it shows via ICON, except
the ID is set to ??????????? and nothing else seems to be registering.
I can highlight it, but I can't launch it.
The captivate I am using is Rooted and running the LagFix Kernal..
However this has never hindered me on Windows or OSX.
Help.. I am trying to go completely Linux.. if it kills me.
See screenshot below: http://img265.imageshack.us/i/sdkbugeclipse.png/
UPDATE: Device is showing in the manager even when not connected?!?!
This has to be some weird Eclipse bug.. PLEASE HELP!
Solution (in case you missed my edit) need to add the correct Samsung Device ID when using the SDK with Ubuntu: link
