I'm having a difficult time with the sdcard option in the Android emulator, on eclipse. It's Eclipse 3.4 on windows. It accepts the timezone option, that is in run configurations, target, the cmd line option is currently '-sdcard c://mysdcard -timezone "America/New_York"'
I've variations on the path, but when I try to save an image from the emulator browser window, It give me a "no sd card found" message.
I've checked google and android docs, also tried placing an image in android_sdk_windows, android_sdk_windows,/tools/ only specifying the image, and in each of the platforms. I also specified int in the eclipse preferences, still no luck.
This should be straightforward, but I'm just starting out with Android. Any help would be most welcome.
Not sure with Eclipse (maybe it does that for you), but from the command line, you should use the 'mksdcard' tool that comes with the SDK
Finally got it working.
Here's the syntax
-sdcard c:\mysdcard.iso -timezone "America/New_York"

I'm new to learning flutter when I try to crate a new project on android studio gives me a arror message in the event section enter image description here
The MESSAGE: [Could not find an option named "platforms". Run 'flutter -h' (or 'flutter -h') for available flutter commands and options.]
And another problem is flutter doctor does not see the android studio enter image description here
1(By the way, I want to use this version of flutter, please do not give a suggestion like update.)
2(this problem did not exist before, it happened after turning my computer off and on)
And sorry for my english mistakes
Thank you.
flutter version flutter_windows_v1.12.13+hotfix.9-stable
andorid studio version: 4.1.3
Is this the answer to your question about andorid studio?
and you need to install JDK
You are using the wrong flutter SDK. Too low information in your question. Make sure that you have the right path to flutter SDK in your IDE. Check that the flutter SDK directory has the appropriate structure, all needed files and cetera. Channel and version of flutter also may have an influence on this problem.
Got this today out of nowhere. Things were going well, but suddenly when I tried to relaunch the app from fresh, for the error Could not find an option named "target"
UPDATE:
This appears to happen when I switch branches and merge while app is running/flutter is attached. If you're using VS Code,
open your launch.json
change something, I decided to change type: "dart" to type: "notdart"
save
try to debug which fails
then revert that change.
This should fix the issue.
Previous Answer/If you're not using VS Code
What worked for me was to
flutter clean
close the editor (VS Code for me)
close the emulator
give a minute for things to close down
open task manager and kill any left over processes of dart.exe flutter.exe and java.exe and adb.exe (was doing Android)
start VS Code/Android Studio and try to debug again. (when prompted I chose to cold boot the emulator as well)
This takes a while as the emulator has to cold boot and since flutter clean was run, the compilation hadto start from scratch as well.
My flutter project is run smoothly in my old laptop. But when I use my new laptop, my flutter project can't run in debug mode.

Is there something missing in the settings on my new laptop? I tried to clean project, upgrade flutter but always fail. Sorry for new
What actually worked for me is, In windows 10 just turn off your mobile hotspot and run the app again. I think it's a glitch/bug in windows 10.
The solution to this problem is deactivating windows hotspot before running build or app compilation.
Don't delete anything or file, just build the app with mobile hotspot turned off.'
its a windows 10 bug that start without any reason. i refreshed my windows and this started
Flutter or Android Applications
The general steps I would use are:
run flutter doctor in terminal
if you are using an emulator make sure it has enough space (often it needs a restart to clear junk files created upon consecutive deploys)
if the gradle files have been modified it is recommended to open them with Android Studio (Android folder of the application). If anything is missing the IDE will prompt you to install the missing dependencies.
Hope it helps
I tried all the above methods but sadly none of them worked. What eventually worked for me was too simple.
first try all the suggested solutions here and if it doesn't work
try to disable mobile firewall, actually I discovered that it's a windows 10 bug because disabling mobile hotspot just until you build or compile your project then you can reenable it without any problem .
Step 1: Open the Registry Editor on your Windows 10 computer. To do this, just press the Windows + R keys on your keyboard. In the Run dialog box, type “Regedit” and hit enter. This will open the Registry Editor window.
Step 2: In the Registry Editor, navigate to the following location:
HKEY_LOCAL_MACHINE SOFTWARE Policies Microsoft WindowsNetwork Connections
Step 3: In the Network Connections key, on the right-side pane, right-click anywhere in the empty area and select New > DWORD (32-bit) Value.
Step 4: Name the newly created registry “NC_ShowSharedAccessUI” and keep its value as “0” to disable the Mobile Hotspot feature on your laptop.
Step 5: To enable the feature, just change the value of the NC_ShowSharedAccessUI registry from 0 to 1 and the feature will be enabled again.
When the functionality has been disabled, the feature will still appear in the Network & Internet settings but it cannot be enabled or configured. To use the feature, the registry needs to be edited again and enable the functionality.
It looks like a memory problem.
In your project folder, Go to android/gradle.properties.
Change the line
From:
org.gradle.jvmargs=-Xmx1536M
To:
org.gradle.jvmargs=-Xmx1024M
Save the gradle.properties file and try to run debugging again.
That Worked for me :)
Usually it Is bcoz of the .gradle file in C:drive.
1.Locate to the .gradle folder (usually in C:\users\your_username)
2.Delete the .gradle folder once located.
2.Locate to your flutter project folder
2.Locate to android
3.Run gradlew clean
4.Run gradlew build
5.now run your app...It worked for me
I tried all the above methods but sadly none of them worked. What eventually worked for me was simple.
There has been a lot of problem with emulator configuration and sometimes it crashes for a lot of reasons. For the above problem what I recommend is, delete the current emulator but remember the settings like API version and all and make a new emulator.
This worked for me fine!
I'll post what solved for me.
flutter clean
flutter run
Close Android studio
Delete your ".gradle" folder
Open android studio as administrator and allow project to build.
For my case i had --no-sound-null-safety in the Dart: Flutter Additional Args ( go to vscode settings under extensions dart ). I deleted it, deleted the web folder in the project ( i was working on the app only ) then reloaded vscode. the error was gone afterwards
go to C:\Program Files\nodejs
Open npm, npm.cmd, npx, npx.cmd
then change the prefix -g to prefix --location=global
still if this did not work,
go to android studio click on build, then click clear project.
I also faced this issue and this step resolved problem. Still if this did not work out let me know.
Non of the solution in here worked for me. running my vscode or android studio as an administrator solved the problem.
Go to file/setting/build,execution,deployment/gradle, and there where Gradle user home: pass static address.
For example, my address is C:/Users/Admin/.gradle.
After applying if runs OK.
There is a simple solution.
Uninstall the app from your device .
Then restart the PC .
First of all Uninstall the application from emulator.
then wipe all data from the emulator.
Sometimes turning off mobile hotspot will do the work.
After turning off if not work then restart the pc or a laptop. Don't turn on mobile hotspot and run flutter run.
I have Fedora 10, it's an old machine.
When I launch the Emulator, it comes up, but I don't
get any initial "Android" display text on the screen, and I've tried
waiting ages.
I installed the Java JDK 7 first then 'android-sdk-r22.2.1-linux.tgz'
and I even set the "alternates" for Java.
I've tried several Emulators, like the 4.3 with the armeabi
and an earlier 3.2. I also tried launching them from the command line with:
emulator -no-audio -gpu off -avd [AVDName] and I even tried '-force-32bit'
but nothing is working.
I've used the Emulator on Windows for a long time, so I'm
very familiar with how to use them, but I just can't get them working on Linux,
what can I try?
Thanks!
This will work:
1) Create a Phone in Eclipse using the Android Virtual Device Manager
(Navigation Bar | Window | Android Virtual Device Manager)
2) Open a terminal in: yourInstallationFolder/sdk/tools
3) Type: ./emulator #theNameofYourPhone -force-32bit
I had exactly the same issue, with the latest build tools - emulator would not launch, adding -debug-init showed that it couldn't get past this line:
ping command: /path/to/android-sdk-linux_86/tools/ddms ping
emulator 22.3.0 "NVIDIA Corporation" "GeForce 8600 GTS/PCIe/SSE2"
"3.3.0 NVIDIA 331.20
But sometimes it worked, it got past this and printed some debug info about display surface, pixel format etc - then emulator was working.
I tried soooo many things, none worked, but it seems I found the solution!
It looks like emulator always starts OK if I launch it from the first virtual desktop! And not working, 'hanging' - when launched from others.
Took some time to figure out, because my main 'development' virtual desktop is a second one :)
Dunno whos bug this is, NVIDIA's, xorg's or emulator's, but I hope this workaround will keep working :)
I have been pulling my hair out on this issue all week... I finally just tried a different DE. I launched an icewm session and the emulator is not running just fine. It seems to be an issue either with GTK or KDE's WM.
Any ways, I hope this helps solve the issues you might be having.
Hey there I've been using the JetBrains IDE support extension for a week now, and While it is great utility. I grow tired of clicking the "X' in the Chrome Yellow Warning ("JetBrains IDE Support" is debugging this tab.)
This may be a noobish question for experienced devs, but does anyone knows how to get rid of this Chrome pop-ups?
Thanks :)
Here is a snapshot:
You can disable this warning in chrome://flags using the Enable Silent Debugging flag:
It's mentioned in the comment #28.
Here is the direct link to the option:
chrome://flags/#silent-debugger-extension-api Just paste this to your Chrome addressbar.
For the ones who didn't understand ( like me :P )
You need to open this address chrome://flags in Google-Chrome and Enable Silent Debugging
While the relevant flag has been removed from chrome://flags, you can still use the command line switch:
chrome --silent-debugger-extension-api
which can be persisted in your flags config (eg. ~/.config/chrome-flags.conf on linux).
See Enable Silent Debugging is not available in Chrome browser
For the newer versions of the Chrome this flag is not available anymore.
So Here is the solution
Open settings in your IDE then head into Tools>Web Browsers
then click on Chrome and hit the pencil icon and
write this in "command line options" finaly hit ok
--silent-debugger-extension-api
now close your chrome if it is open then try to launch it again using debug or run...
Today I installed the latest version of Eclipse, Android SDK and AVD plugin. But I have a tedious problem. When I want to quit the emulator (with the X button), the emulator freezes and I can't click anything there anymore. Obviously it has something to do with the sound, because when I execute "pulseaudio -k" in console, the emulator quits.
Due to this fact, I tried the following to let the emulator at least run properly:
In Preferences->Android->Launch -> Default Emulator option -> -noaudio
and
Run Configuration -> Android Application -> [Application] -> Target -> Addidtional Emulator Command Line Options -> -noaudio
But nothing helps. Emulator stays frozen. Actually I want audio to run, but switching it off doesn't work either. So what can I do?
I replied on the issue, but just if interested:
you may need to disable audio output instead, this is not desirable for me, so just select alsa (or esd/oss) by setting environment variable
QEMU_AUDIO_DRV=alsa
Looks like there is no way to specify audio drivers in hardware.ini so the best solution is going to sdk tools directory, rename emulator in emulator.real and make a shell script named emulator containing:
#!/bin/sh
export QEMU_AUDIO_DRV=alsa
exec $(dirname $0)/emulator.real $*
then chmod 755 emulator
It's this problem described here:
http://code.google.com/p/android/issues/detail?id=17294
There is a workaround so that you can quit the emulator:
Set in your virtual devices "Audio Playback Support" and "Audio recording support" to "no".
