Build fails after install

[loxi5]

When the library is installed, building app fails with the following error:

FAILURE: Build failed with an exception.

• What went wrong: A problem occurred configuring project ':pusher_channels_flutter'.

  Could not create an instance of type com.android.build.api.variant.impl.LibraryVariantBuilderImpl. Namespace not specified. Specify a namespace in the module's build file. See https://d.android.com/r/tools/upgrade-assistant/set-namespace for information about setting the namespace.

If you've specified the package attribute in the source AndroidManifest.xml, you can use the AGP Upgrade Assistant to migrate to the namespace value in the build file. Refer to https://d.android.com/r/tools/upgrade-assistant/agp-upgrade-assistant for general information about using the AGP Upgrade Assistant.

i faced the same problem when i tried to upgrade flutter to 3.19.3 i get asked to upgrade my build.gradle as the flutter docs says then i faced this error

i fixed it by adding this line inside android { // Conditional for compatibility with AGP <4.2. if (project.android.hasProperty("namespace")) { namespace 'com.pusher.channels_flutter' } inside the android/build.gradle for the pusher package source code

I have the same issue. Someone knows how can I solve it

for me this worked

Created a file on root android folder named pusher_channels_flutter_fix.gradle and added this content

subprojects { subproject ->
    if (subproject.name == 'pusher_channels_flutter') {
        subproject.afterEvaluate {
            // Remove the package attribute from the AndroidManifest.xml
            def manifestFile = file("${subproject.projectDir}/src/main/AndroidManifest.xml")
            if (manifestFile.exists()) {
                def manifestContent = manifestFile.text
                manifestContent = manifestContent.replaceAll('package="com.pusher.channels_flutter"', '')
                manifestFile.text = manifestContent
            }

            // Add the namespace property to build.gradle
            subproject.android {
                namespace = 'com.pusher.channels_flutter'
            }
        }
    }
}

then at the end of build.gradle I added this line

apply from: 'pusher_channels_flutter_fix.gradle'

Was having two issues for both the manifest and the namespace

At least for me this worked! Hope it helps you also

I got this message * What went wrong: A problem occurred evaluating root project 'android'.

Could not read script '/Users/io/Trabajo/test/project/android/pusher_channels_flutter_fix.gradle' as it does not exist.
