Since the system update of my Vivo y20i device, I am having trouble installing my flutter app. When I run (Ctrl+F5) my app it get stuck in Running Gradle task 'assembleDebug'... sometimes it is stuck in Installing build/app/outputs/apk/app.apk. My developer option is turned on and also the USB Debugging, I tried every solutions that I found here in stackoverflow and other websites:

  1. I run the ./gradlew clean and ./gradlew build and also tried ./gradlew clean build
  2. Uninstall the app in my device then flutter clean. I always do the flutter clean
  3. I uninstall everything, Android Studio and VSCode, and I upgrade my Flutter SDK to 2.5.0, and also did this.

but I am still facing the same problem. When I try flutter run -v, it works but then I can't update my app or do any changes in the app. Please help.

Here is my flutter doctor -v enter image description here

Sometimes the problem can be with ADB Server. Run this:

adb kill-server

Connect your device again and it should work.

Also

Settings>>Accounts and sync>>Delete Work Profile or any User Profile created on your phone.

  • didn't work too but I guess my problem is really my device. – CodeFloat Sep 14 '21 at 17:22
  • The app you are testing was it ever installed on the phone. – Priyansu Choudhury Sep 14 '21 at 18:19
  • yes, I was able to run the app and then suddenly it is not running anymore just stuck in "Running Gradle assembleDebug" or "Installing build/app/outputs/apk/app.apk". I didn't do anything, all I remember is that my phone system update last friday. – CodeFloat Sep 14 '21 at 19:53
  • Is the app is still on your phone? Check in the settings for all applications, this mostly happens because the app remains installed for a different user on the phone. The solution is to go to that app info click the three-dot menu on top and select uninstall for all users. – Priyansu Choudhury Sep 14 '21 at 22:00
