AndroidX が minSdkVersion 19 に移行

AndroidX ライブラリは、2023 年 10 月のリリースから、サポートされるデフォルトの最小 Android API レベル 19 (以前は 14) に移行します。Play ストアのチェックイン データによると、ほぼすべての Android ユーザーが API 19 以降のデバイスを使用しているため、API レベル 19 ではなくなりました。レガシーバージョンをサポートするために必要です。この変更は、AndroidX ライブラリがアプリ開発者の潜在的なユーザー数を最大化し、Google Play ServicesおよびAndroid NDKと連携するのに役立ちます。

現在、より低い minSdkVersion をサポートしている場合は、その値を 19 に増やし、以前のバージョンをサポートするようにコードをクリーンアップすることをお勧めします。ビジネス上の理由でそれができない場合は、AndroidX の以前のバージョンを使用し続けることをお勧めします。

「API レベル 19」てのは、「Android OS 4.4 / Kitkat」です。

10年前ぐらいにリリースされました。

Unresolved reference: BuildConfig

Android Gradle Plugin (AGP) 8.0 以降、BuildConfig ファイルの生成はデフォルトで無効になっており、必要なモジュールに対してのみ手動で有効にする必要があります。

モジュール別であれば、


// build.gradle.kts

android {

エラーメッセージを見てみる。


5 issues were found when checking AAR metadata:


  1.  Dependency 'androidx.navigation:navigation-common:2.7.0-beta02' requires libraries and applications that
      depend on it to compile against version 34 or later of the
      Android APIs.

      :app is currently compiled against android-33.

      Also, the maximum recommended compile SDK version for Android Gradle
      plugin 8.0.1 is 33.

      Recommended action: Update this project's version of the Android Gradle
      plugin to one that supports 34, then update this project to use
      compileSdk of at least 34.

      Note that updating a library or application's compileSdk (which
      allows newer APIs to be used) can be done separately from updating
      targetSdk (which opts the app in to new runtime behavior) and

長いですが要するに、


androidx.navigation:navigation-compose:2.7.0-beta02

が依存している以下、


androidx.navigation:navigation-common:2.7.0-beta02
androidx.navigation:navigation-runtime:2.7.0-beta02
androidx.navigation:navigation-common-ktx:2.7.0-beta02
androidx.navigation:navigation-runtime-ktx:2.7.0-beta02

は、


Android API 34

以上を必要としているので使えません。

ということのよう。

 

💉 なぜ私は、Android API 33 だったけか

「Flamingo」なのでそれが最新安定版。

androidx.navigation:navigation-compose が 2.7.0-beta02 で NG だが 2.7.0-beta01 で OK な件

Android Studio Flamingo | 2022.2.1 を使ってる場合、33 までです。
