Mobile versionSchritte:
- Überprüfte meine Java-Version: Mein System hatte eine Java-Version 21.0.5, diese ist jedoch nicht für die Verwendung konfiguriert, da die Umgebungsvariable JAVA_HOME nicht festgelegt ist. Daher wird das mit Android Studio gelieferte Standard-Java verwendet, das Version 21.0.4 ist, wie in der Ausgabe von flutter doctor --verbose angegeben.
Überprüfte die Kompatibilitätsmatrix und verwendete im folgenden Konfigurationsprozess die beiden Gradle-Versionen 8.4 und 8.5 parallel zur Java-Version 21.< /p> - Öffnete ein Terminal, ging zum Verzeichnis
/android/ und führte die folgenden Befehle aus:Code: Select all
./gradlew wrapper --gradle-version=8.4
