Add support for compileSdk 37

[rahul-lohra]

Goal

Make the convention plugins usable by consumer projects that build on Android Gradle Plugin 9.x (required for compileSdk/targetSdk = 37, Android 17), while remaining compatible with AGP 8 consumers.

Current problem

The published plugin is compiled against AGP 8.11.1, where com.android.build.api.dsl.CommonExtension is generic (CommonExtension<*, *, *, *, *, *>) and exposes block-DSL functions (compileOptions {}, testOptions {}, sourceSets {}, buildTypes {}).

In AGP 9, CommonExtension is non-generic and those block-DSL functions were removed — only the getters remain (getCompileOptions(), getTestOptions(), …). As a result, when a project on AGP 9 applies these plugins, configuration fails at runtime:

NoSuchMethodError: void com.android.build.api.dsl.CommonExtension.compileOptions(kotlin.jvm.functions.Function1)

(0.13.1's bytecode calls a method that no longer exists.) This blocks any consumer from moving to AGP 9 / compileSdk 37.

Implementation

• Bump compile-time AGP 8.11.1 → 9.1.1 (gradle/libs.versions.toml) so the plugin compiles against the AGP-9 DSL. (compileOnly — does not force consumers onto AGP 9.)

• BaseConfiguration.kt / coverage/CoverageConfiguration.kt — in the configureAndroid<Ext>() helpers:

  • Drop the generic args: CommonExtension<*, *, *, *, *, *> → CommonExtension.
  • Replace the removed block DSLs with getter/property access:
    • compileOptions { … } → compileOptions.apply { … }
    • testOptions { unitTests { … } } → testOptions.unitTests.apply { … }
    • sourceSets { all { … } } → sourceSets.all { … }
    • buildTypes { getByName("debug") { … } } → buildTypes.getByName("debug") { … }

  This is required because member resolution inside <reified Ext : CommonExtension> binds to the upper bound (CommonExtension), so the block DSLs can't be used even though callers pass concrete ApplicationExtension/LibraryExtension/TestExtension.

• The getters used (getCompileOptions, getTestOptions().getUnitTests(), getSourceSets(), getBuildTypes()) exist in both AGP 8 and 9, and .all {} / .getByName(name) {} only configure existing elements (safe under the ? extends variance) — so no @Suppress casts and no break for AGP 8 consumers.

Testing

• ./gradlew :plugin:compileKotlin and publishToMavenLocal succeed.
• Consumed from a real AGP-9.1.1 / compileSdk-37 project (stream-video-android): the prior NoSuchMethodError is gone and all modules configure and compile.
