在实体android错误上运行flutter应用程序

Question

I try to run the app onto my physical android phone, and i get this error

Error: ADB exited with exit code 1
adb: failed to install /Users/User/AndroidStudioProjects/appname/build/app/outputs/apk/app.apk: Failure [INSTALL_PARSE_FAILED_BAD_PACKAGE_NAME: Invalid manifest package: must have at least one '.' separator]
Error launching application on Pixel XL.

I had just updated my flutter from v.0.3.1 to v.0.7.3 and also prepped it for deployment and now im getting this error

i have no idea how to go about fixing this, does anyone have any suggestions?

Answer 1

This error is because you have capital letters in your package name like this.

Com.example.anubhav;

You need to change it to small letters:

com.example.anubhav;

You can refer to this SO post which tells you how to change package name in flutter.

Answer 2

It's a error to install your app at your mobile emulator, you have to clean it:

1. Open AVD Manager
2. Wipe Data (delete datas from emulator)
3. Open emulator
4. Try to run app

Answer 3

In this case it's give you alert in your physical device for installation of App. please allow to install option.
