This above is full bug report

Same here. It stopped working since latest Flutter upgrade. Works in debug mode but not in release.

christocracy · 2024-05-19T08:15:25Z

Post both your gradle files.

nobody is specifying what version of the plug-in they’re using.

Z6P0 · 2024-05-19T16:18:50Z

build.gradle:

allprojects {
    repositories {
        google()
        jcenter()
        maven { url "${project(':background_fetch').projectDir}/libs" }
    }
}

rootProject.buildDir = '../build'
subprojects {
    project.buildDir = "${rootProject.buildDir}/${project.name}"
    project.evaluationDependsOn(':app')
}

tasks.register("clean", Delete) {
    delete rootProject.buildDir
}

Using latest plugin version and latest Flutter version.

christocracy · 2024-05-19T16:24:49Z

First-of-all, the maven repo jcenter() has been deprecated since 2021.

second, you’ve not fully implemented the Android setup instructions linked in the readme (the ext vars).

I suggest you generate a fresh hello-world app and compare the changes in the default build.gradle with those in your own app.

you’ve failed to properly upgrade your app with the latest requirement of the latest flutter SDK. That’s why you have problems.

I am getting same issue

christocracy · 2024-05-23T12:22:00Z

See my comment above: #369 (comment)

you did not fully implement the Setup Instructions (ext vars). Go back and review the Setup Instructions. Yes, they are important.

I just have added below ext code in android/build.gradle after allprojects{}, and use them in android/app/build.gradle as the presentation of the help doc Android Setup, it has solved the problem on my side.

Try to add below ext code in android/build.gradle under allprojects{}, and use them in android/app/build.gradle as the presentation of the help doc Android Setup

allprojects {

sahilsharma17 · 2024-08-14T06:34:13Z

I have tried this but the problem is same, can not build the release apk.
I guess it is some issue with the new release and dependencies.

YumanYIN · 2024-08-14T08:01:57Z

I have tried this but the problem is same, can not build the release apk. I guess it is some issue with the new release and dependencies.

I'm also using Flutter 3.24.0, but I can build the release APK.
You can try to do the below code in the android/app/build.gradle :

android {
    def buildConfig = rootProject.extensions.getByName("ext")
    
    compileSdk buildConfig.compileSdkVersion 

    defaultConfig {
       ...
       targetSdkVersion buildConfig.targetSdkVersion
       ...
    }
    ...
}

If the problem is still there, you need to post your android/build.gradle and android/app/build.gradle to help you analyse the reason.

Aziz-T · 2024-08-14T08:08:39Z

This problem is related to the compileSdkVersion and targetSdkVersion of the plugins. This problem occurs because the compileSdkVersion and targetSdkVersion of some plugins are outdated. Either go to the source files of the plugin in your project and make the compileSdkVersion and targetSdkVersion versions the same as your project (version 34 compatible), or add the code block below to the build.gradle file in your project directory.

subprojects { afterEvaluate { android { compileSdkVersion 34 } } }

This code is a Gradle configuration script used in Android projects. The subprojects block allows you to configure certain settings for all subprojects (modules) in the project. The android block inside defines Android-related configuration settings, and the compileSdkVersion 34 line allows projects to be compiled with Android API 34.

christocracy · 2024-08-14T08:29:23Z

Post both your .gradle files.

Aziz-T · 2024-08-14T10:39:26Z

christocracy · 2024-08-14T12:20:01Z

Post the entire contents of both your gradle files:

YumanYIN · 2024-08-14T13:15:48Z

subprojects { project.buildDir = "${rootProject.buildDir}/${project.name}" } subprojects { project.evaluationDependsOn(":app") }

tasks.register("clean", Delete) { delete rootProject.buildDir } `

You have not added maven { url "${project(':background_fetch').projectDir}/libs" } in allprojects , follow this doc: Android Setup

allprojects {
    repositories {
        google()
        mavenCentral()
        // [required] background_fetch
        maven { url "${project(':background_fetch').projectDir}/libs" }
    }
}

christocracy · 2024-08-14T13:21:28Z

@Aziz-T i suggest you consult with the required Android Setup Instructions, linked in the readme and carefully follow ALL the instructions.

If you are like me and have updated to the new Flutter version, You can consider this temporary solution
livekit/client-sdk-flutter#569 (comment)

christocracy · 2024-08-15T00:56:50Z

My plug-ins never hard-code sdk versions, they read them from ext vars in your build.gradle. All plugin authors should do this but most don’t.

we learned to do this years ago in the React Native world.

background_fetch

100% working solution:

the problem is with background_fetch package that you used in pubspec.yaml. comment or remove this package then make the build. it will must work.

note: the to find the problem: when you get the error check the direction first.ERROR:/home/sonu/projects/flutter/H-ATTENDANCE/build/background_fetch/intermediates/merged_res/release/values/values.xml:2520: AAPT: error

so here: search immediate folder after build folder. here immediate folder is 'background_fetch'. so, the problem is in backgroudn fetch package. there may have file missing when the package is downloaded. this is why the error(resource android:attr/lStar not found) came.

christocracy · 2024-09-02T21:21:16Z

@RahajulAminRaju

100% working solution:

No!. This error is typically associated with the Android dependency androidx.appcompat.appcompat

check your appCompatVersion.

https://github.com/transistorsoft/flutter_background_fetch/blob/master/help/INSTALL-ANDROID.md#open_file_folder-androidbuildgradle

people having problems with this likely have multiple plugins importing different versions of this dependency.

Consult https://maven.google.com appcompat.

to see a dependency tree of your app, execute:

$ ./gradlew app:dependencies

christocracy · 2024-09-02T21:26:37Z

This plug-in is happy to import any version of appcompat that you wish. As the Setup Instructions remark “or higher / as desired”

{
  appCompatVersion  = "1.4.2" // or higher / as desired
}

diegocontini · 2024-09-03T12:12:51Z

I was facing this issue, and finded a fix to my case.
Sharing just in case help someone.

In my case, the issue was the PDF package and PRINTING package.

Upgraded to this versions and fixed the issue:
pdf: ^3.11.1
printing: ^5.13.2

If you use firebase too, consider reading this PR: firebase/flutterfire#13200

The problem only occurs in release mode, not debug.
I've tried updating the app/build.gradle & android/build.gradle, but the error persists.

Try version 1.3.6 (just released). I've removed the android dependency androidx.appcompat:appcompat from the plugin's build.gradle (it turns out it's not required).

a-v-ebrahimi · 2024-09-15T08:45:53Z

Add this to android/build.gradle

subprojects {
        afterEvaluate { project ->
            if (project.hasProperty('android')) {
                project.android { compileSdkVersion 34 }
            }
        }
}

christocracy · 2024-09-17T15:02:07Z

In version 1.3.7, I have removed the appcompat dependency.

Add this to android/build.gradle

subprojects {
        afterEvaluate { project ->
            if (project.hasProperty('android')) {
                project.android { compileSdkVersion 34 }
            }
        }
}

This plugin does not require this if you provide the required ext vars (including ext.compileSdkVersion) in your root build.gradle, as documented in the Android Setup Instructions

Of course, other plugins may have hard-coded compileSdkVersion, requiring that override, but this plugin does not.
