Problem:

If I want to open the APK:

1. the app opens perfectly
2. the screen is black
3. the app goes in the background

Notes:

If I run flutter run --release the app opens perfectly but it also shows an error:

Error: ADB exited with exit code 1
Performing Streamed Install

adb: failed to install C:\Users\Flutter\StudioProjects\nomadnet2\build\app\outputs\flutter-apk\app.apk: Failure [INSTALL_FAILED_UPDATE_INCOMPATIBLE: Package com.apps.social_circle signatures do not match previously installed version; ignoring!]

If I run: flutter run it works perfectly

I already tried:

1. upgrade the packages
2. install flutter SDK again
3. update flutter

I also tried more things but I don't know them anymore

Please help me!

Try to delete your previus APK in

C:\Users\Flutter\StudioProjects\nomadnet2\build\app\outputs\flutter-apk\app.apk

Then use the command

flutter clean

And pub get your pubspect.yaml

and try to run the release version again

CodePudding user response：

Delete your previously installed app in your phone or emulator, and run release again, probably is because a different sign key.
