【Flutter】アプリ名変更でAndroid resource linking failedエラー

投稿日：2023年11月1日

TripLearnerDiaryという名前でアプリを公開していたのだが、意味が分からないのでAchieve Diaryに名前を変更したいと思う。

アプリ名を変更する時には、android\app\src\main\AndroidManifest.xmlを更新すれば良いのだが、これだけではエラーになってしまった
変更前のアプリ名：TripLearnerDiary
変更後のアプリ名：AchieveDiary

更新した部分

&lt;application
        android:label="@string/AchieveDiary"
        android:name="${applicationName}"
        android:icon="@mipmap/ic_launcher">
...

<application

android:label="@string/AchieveDiary"

android:name="${applicationName}"

android:icon="@mipmap/ic_launcher">

...

解決方法

追加でandroid\app\build.gradleも更新する必要がある

変更前

buildTypes {
        debug {
            debuggable true
            applicationIdSuffix ".dev"
            resValue "string", "TripLearnerDiary", "Debug TripLearnerDiary"
        }
        release {
            debuggable false
            applicationIdSuffix ""
            resValue "string", "TripLearnerDiary", "TripLearnerDiary"

            apply from: './signing/signing.gradle', to: android
            signingConfig signingConfigs.release
        }
    }

buildTypes {

debug {

debuggable true

applicationIdSuffix ".dev"

resValue "string", "TripLearnerDiary", "Debug TripLearnerDiary"

}

release {

debuggable false

applicationIdSuffix ""

resValue "string", "TripLearnerDiary", "TripLearnerDiary"

apply from: './signing/signing.gradle', to: android

signingConfig signingConfigs.release

}

変更後

buildTypes {
        debug {
            debuggable true
            applicationIdSuffix ".dev"
            resValue "string", "AchieveDiary", "Debug Achieve Diary"
        }
        release {
            debuggable false
            applicationIdSuffix ""
            resValue "string", "AchieveDiary", "Achieve Diary"

            apply from: './signing/signing.gradle', to: android
            signingConfig signingConfigs.release
        }
    }

buildTypes {

debug {

debuggable true

applicationIdSuffix ".dev"

resValue "string", "AchieveDiary", "Debug Achieve Diary"

}

release {

debuggable false

applicationIdSuffix ""

resValue "string", "AchieveDiary", "Achieve Diary"

apply from: './signing/signing.gradle', to: android

signingConfig signingConfigs.release

}

これでBuildしなおせばOK
フォルダ名など昔のアプリ名のままだが一旦無視して更新してみる

pubspec.yamlのversion番号を更新
flutter clean
flutter build appbundle
作成されたファイルをGoogle Consoleにアップロード

なお、Google Playで公開するアプリ名はGoogle Console＞ストアでの表示＞メインのストアの掲載情報　で変更できる
