Post your gradle dependencies:

$ cd android 
$ ./gradlew app:dependencies

christocracy commented 5 months ago

Also review the Android Setup Instructions where it was recommended to use gradle ext vars use ext.compileSdkVersion, ext.targetSdkVersion rather than hard-coding in your app/build.gradle (where 3rd party plug-ins cannot be aware of):

compileSdkVersion 34

There are plenty of post about this in SO:

Thank you so much! I fixed this issue.

Added these codes on app/build.gradle

android {

    compileSdkVersion rootProject.ext.compileSdkVersion

    buildTypes {
        release {            
            signingConfig signingConfigs.debug
            // signingConfig signingConfigs.release
            minifyEnabled true
            shrinkResources false
            proguardFiles "proguard-rules.pro"
            proguardFiles "${background_geolocation.projectDir}/proguard-rules.pro"
        }
    }

    configurations.all {
        resolutionStrategy {
            force 'androidx.core:core:1.6.0'
            force 'androidx.core:core-ktx:1.6.0'
        }
    }
}

dependencies {
    implementation 'androidx.appcompat:appcompat:1.3.0'
    implementation 'androidx.core:core-ktx:1.6.0' 
}

Removed gradle dependencies on android/build.gradle


ext {
    compileSdkVersion   = 34
    appCompatVersion    = "1.4.2"
    playServicesLocationVersion = "21.1.0"
    hmsLocationVersion  = "6.12.0.300" 
    removeBackgroundGeolocationDebugSoundsInRelease = false
}

buildscript {
    ext.kotlin_version = '1.8.10'
    repositories {
        google()
        mavenCentral()
    }

    dependencies {
        // classpath "com.android.tools.build:gradle:8.3.1"
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        classpath 'com.google.gms:google-services:4.3.15'
    }
}

allprojects {
    repositories {
        google()
        mavenCentral()
        maven { url "${project(':flutter_background_geolocation').projectDir}/libs" }
        maven { url 'https://developer.huawei.com/repo/' }
        maven { url "${project(':background_fetch').projectDir}/libs" }
    }
}

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

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

By my test, this command only working on debug mode. (signingConfig signingConfigs.debug)

flutter build apk --release

And this command is working well on release mode. ( signingConfig signingConfigs.release)

flutter build appbundle

Hope it will help to others that facing this issue... Thank you for a great support!

christocracy commented 5 months ago

I do not like this:

dependencies {
    implementation 'androidx.appcompat:appcompat:1.3.0'
}

You should not need to manually add that (and certainly not an old version 1.3.0 from May 2021.

The latest version of appcompat is 1.7.0

Yes, you are right. Thank you!
