thanks in advance.
I have faced this problem before, Try these steps:
Open your android studio, go to avd manager
Now select your emulator, click on dropdown in actions and wipe data
Check whether you have intel x86 emulator accelerator ticked in sdk tools in android studio.
If the problem still persists, you can remove this emulator and install a new one.

I am unable to install my apk on an android device except only for this apk. I am using the flutter build apk command to generate apk. After sharing apk to some device it was getting app not installed as shown in this..
I am using VSCode and here I am sharing the flutter doctor

Other apk's are working fine except this one on my device.
Try all these steps:
Make sure that you have enough storage space
Enable the installation from Unknown Sources
Make sure that the APK file isn’t corrupted or incomplete
try to clear cache of package installer and reboot
Check if the app is already installed in your device.
Check if the play protect option is enabled, if it is then turn off it in play store from navigation drawer.
Make sure “applicationId” in build.gradle file is unique.
Just go to the Settings --> Apps --> Click on your App. ---> In App info page at the action bar menu there will be an option called " Uninstall for All users " click that.
This type of issue is occur when you transfer apk file directly via any messaging platform or USB ... Some time it will happen and apk file will corrupt.. So I suggest to create a link for distribution of your app..
You can upload your apk in Google drive or use Firebase App Distribution or just WeTransfer. And Generate the link and then transfer that link....
So yesterday i upgraded flutter to 2.5 and flutter doctor said android-licenses status unknown. So, I ran flutter doctor --android-licenses and it says that sdkmanager not found although the previous version which was probably 2.2.3 didn't say anything like that. I did not install cmdline-tools the "android studio" way. I followed a guide and downloaded the android cmdline-tools.zip file, unpacked it inside "android" folder, made a new tools folder (inside android folder) and copied everything from the android folder to the tools folder. Then I set path to sdkmanager, platform-tools and emulator.
After that I installed platform-tools 31.0.0, android-sdk 31.0.0 and an emulator. At that time flutter was able to recognise sdkmanager and it gave no errors. How do i solve this? Did something related to where the sdkmanager should be located change?

cmdline-tools are installed to resolve this.
Also i can run the default app just fine.
I am running linux.
For Windows, you can use this command:
flutter config --android-studio-dir="Path to your Android Studio"
Double check that inside Android Studio > SDK Manager > SDK Tools, Android SDK Command-line Tools are installed.

i can't rename ' aditya jain' folder to 'adityajain'...it takes space....pls help mee.
please help and thanks community!!
If the path name has spaces, you can wrap the path with double quotes. This allows Windows to identify the path as a single String: "C:\Users\aditya jain\Downloads\Android\AndroidStudio"
If you have already configured SDK path for Flutter (flutter config --android-sdk ) and yet not working than...
Install the platform-tools resolves the problem.
Go to the SDK Manager (top-right in the toolbar), then open SDK Tools, then check-mark ✅ Android-SDK Platform-Tools and apply the changes (As shown below).
For me this solution worked.
Enjoy...

I created a my_app folder and typed:
cd my_app
flutter run
The "flutter run" command does not work. How to fix this?
Have you installed android sdk?
If not then installing Android Studio will will install all the required dependencies.
I faced this problem it easy to solve
Open Android Studio
And go to preference
Plugins
Download flutter & dart
You need Android SDK, if you plan on using Android Studio then SDK will be downloaded with the Android Studio
https://developer.android.com/studio is the link to download
I am facing a problem with the flutter web initialization. I followed the steps in https://flutter.dev/docs/get-started/web Everything went smooth

I don't have chrome beta on my PC anymore. I have normal chrome. How to change it. Somebody help me out.
Also, I got found this online as a solution but I don't know what it means.
export CHROME_EXECUTABLE=path/to/chrome
This is not the solution but an alternative method you can try. If you are in the beta channel of flutter you can just type flutter build web that will create a web build in your web folder. You can run it on any other server just like normal web application. If you want to do this to an existing project first run flutter create . then flutter build web.
