Bermigrasi ke Kotlin 2.0
Jika Anda menggunakan Consumer SDK for Android 3.0+, Anda harus mengupgrade ke Kotlin 2.0. Halaman ini memberikan panduan untuk mempermudah transisi ke versi Kotlin baru.
Kompatibilitas Gradle dan AGP
Kotlin 2.0 memiliki persyaratan untuk versi minimum dan maksimum
untuk versi Gradle dan Plugin Android Gradle (AGP) Anda. Pastikan project Anda memenuhi persyaratan ini untuk Kotlin 2.0.
Versi minimum AGP untuk Consumer SDK 3.0+
Consumer SDK 3.0 mengharuskan penggunaan AGP 7.3+.
Mode R8 penuh
Consumer SDK v3 dan yang lebih lama tidak mendukung mode R8 Penuh. Anda harus menonaktifkan mode R8 Penuh secara eksplisit jika aplikasi Anda menargetkan AGP 8.0+.
#settings.gradleandroid.enableR8.fullMode=false
Kompatibilitas versi Kotlin
Kotlin mendukung kompatibilitas mundur dengan tiga versi bahasa
sebelumnya.
Artinya, jika Anda sudah menggunakan Kotlin 1.7+ dengan Consumer SDK, Anda
dapat mengupgrade ke Kotlin 2.0 tanpa harus menyelesaikan semua perubahan yang
merusak. Namun, kompatibilitas Kotlin hanya berlaku untuk fitur bahasa yang stabil.
Jika Anda menggunakan fitur alfa, beta, atau eksperimental dalam bahasa Kotlin,
Anda mungkin harus melakukan perubahan tambahan saat mengupgrade.
Flag ini mengembalikan perubahan yang merusak perilaku versi Kotlin sebelumnya.
Misalnya, jika Anda menggunakan Kotlin 1.7, Anda dapat menentukan [ -
language-version 1.7] dan perubahan yang menyebabkan gangguan baru tidak akan berlaku lagi:
android{kotlinOptions{languageVersion='1.7'}}
api-version X.Y
Flag ini mencegah penggunaan API baru sebelum kode hilir yang bergantung siap untuk menggabungkan Kotlin 2.0.
android{kotlinOptions{apiVersion='1.7'}}
Pendekatan yang lebih bertarget
Selain menggunakan tanda kompatibilitas Kotlin, sebaiknya tinjau catatan rilis Kotlin dan pilih perilaku yang ingin Anda pertahankan dari versi yang Anda upgrade. Kotlin menyediakan daftar perubahan yang merusak dan tanda yang dapat ditetapkan untuk mempertahankan perilaku asli dalam panduan kompatibilitasnya untuk setiap versi:

Ensure that your\nproject meets these requirements for Kotlin 2.0.\n\nAGP minimum version for the Consumer SDK 3.0+\n\nConsumer SDK 3.0 requires using AGP 7.3+.\n\nFull R8 mode\n\nConsumer SDK v3 and below does not support Full R8 mode. You must explicitly\ndisable Full R8 mode if your application targets AGP 8.0+. \n\n # settings.gradle\n android.enableR8.fullMode=false\n\nKotlin version compatibility\n\nKotlin supports backwards compatibility with [three previous language\nversions](https://kotlinlang.org/docs/kotlin-evolution-principles.html#compatibility-options).\nThis means that if you are already using Kotlin 1.7+ with the Consumer SDK, you\nshould be able to upgrade to Kotlin 2.0 without having to resolve all of the\nbreaking changes. However, [Kotlin compatibility only applies to stable language\nfeatures](https://kotlinlang.org/docs/components-stability.html#stability-levels-explained).\nIf you are using alpha, beta or experimental features in the Kotlin language,\nthen you may have to make additional changes when upgrading.\n\nKotlin compatibility flags\n\nAs noted in the previous section, Kotlin supports up to 3 previous versions of\nthe language when upgrading. Kotlin [supplies two flags to help with limiting\nbreaking changes](https://kotlinlang.org/docs/compatibility-modes.html):\n\nlanguage-version X.Y\n\nThis flag reverts breaking changes to the behavior of a previous Kotlin version.\nFor example, if you are using Kotlin 1.7, you could specify `[ -\nlanguage-version 1.7]` and the new breaking changes would no longer take effect: \n\n android {\n kotlinOptions {\n languageVersion = '1.7'\n }\n }\n\napi-version X.Y\n\nThis flag prevents new APIs from being used before dependent downstream code is\nready to incorporate Kotlin 2.0. \n\n android {\n kotlinOptions {\n apiVersion = '1.7'\n }\n }\n\nA more targeted approach\n\nIn addition to using Kotlin compatibility flags, we recommend reviewing the\nKotlin release notes and choosing the behaviors that you would like to retain\nfrom the version that you are upgrading from. Kotlin provides a list of breaking\nchanges and the flags that can be set to retain the original behavior in its\ncompatibility guides for each version:\n\n- [1.8 compatibility guide](https://kotlinlang.org/docs/compatibility-guide-18.html)\n- [1.9 compatibility guide](https://kotlinlang.org/docs/compatibility-guide-19.html)\n- [2.0 compatibility guide](https://kotlinlang.org/docs/compatibility-guide-20.html)"]]
