Simple Proplem, hard to solve (i think),
I get this error when i start my main.dart:
Error:
Overlay manifest:package attribute declared at AndroidManifest.xml:2:5-34 value=(com.example.Scanner)
has a different value=(com.example.Scanner) declared in main manifest at AndroidManifest.xml:1:70-97
Suggestion: remove the overlay declaration at AndroidManifest.xml and place it in the build.gradle:
flavorName {
applicationId = "com.example.Scanner"
}
FAILURE: Build failed with an exception.
This is my build.gradle:
defaultConfig {
// TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
applicationId="com.example.Scanner"
minSdkVersion 16
targetSdkVersion 29
versionCode flutterVersionCode.toInteger()
versionName flutterVersionName
}
and this is my AndroidManifest.xml:
package="com.example.Scanner">
I hope someone can help me, otherwise i can´t program at this app anymore:(
After removing package="com.example.Scanner"
i get this error:

With the work from Midhun MP [https://stackoverflow.com/users/1104384/midhun-mp]:
Remove the package attribute from androidmanifest and check
i got one error done. Then i got a new java error. I only copied a AndroidManifest.xml from an old project to a new and it worked. This worked for me:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.Scanner">
<!-- io.flutter.app.FlutterApplication is an android.app.Application that

FlutterApplication and put your custom class here. -->
<application

, but i have no idea what was wrong. I never changed it or so. Just change package="com.example.YOURNAME">
and android:label="YOURNAME"
I also had the same issue but after going through the following steps I got my point;
Your package name "com.example.com"(in your case It could be different) should be same in 5 locations, like eg
1. android/app/src/debug/AndroidManifest.xml
2. android/app/src/main/AndroidManifest.xml
3. android/app/src/profile/AdroidManifest.xml
4. buildgradle
file defaultConfig { applicationId ""}
5. MainActivity.java
on "package" OR MainActivity.kotlin
In my case my package name was com.example.blog_daily. So I rewrite all the packages with the same name at all the points and solved my issue.
first make all package name same //to do this search your package name in search bar that show in terminal and fixed them// then run flutter clean and flutter pub get. now you can run flutter run. I think it will solve your problem.
Hello,
I had the same issue, and I changed the package name in 5 location.
1.) android/app/src/debug/AndroidManifest.xml
2.) android/app/src/main/AndroidManifest.xml
3.) android/app/src/profile/AdroidManifest.xml
4.) buildgradle file defaultConfig { applicationId ""}
5.) MainActivity.java on "package" OR MainActivity.kotlin
After modifying the above files, the Flutter App run without any issues.
