Target Android 14

[AaronChen0]

This is an attempt to update shadowsocks-android to target Android 14 and its dependencies.

Please read this for changes in AGP8. Some build option default values change.

The build succeeded and the debug apk works in both my android 14 and android 12 phones. You can try a debug build apk here. The debug build log can be found here.

Main updates:

• Bump shadowsocks-rust from 1.15.3 to 1.20.4
• Bump gradle from 7.6 to 8.10
• Bump Android Gradle plugin from 7.4.2 to 8.5.2
• Bump Kotlin from 1.8.10 to 2.0.10
• Migrate from kapt to KSP. Ref: https://developer.android.com/build/migrate-to-ksp
• Add foreground service type to manifest. Ref: https://developer.android.com/about/versions/14/changes/fgs-types-required

In a release branch here, the build will fail with the following R8 missing class errors:

WARNING: /home/circleci/code/mobile/build/intermediates/merged_java_res/release/mergeReleaseJavaResource/base.jar: R8: Unexpected reference to missing service class: META-INF/services/java.net.spi.InetAddressResolverProvider.

Adding the following to proguard-rules.pro fixes the R8 errors and the apk works normally.

-dontwarn java.net.spi.InetAddressResolverProvider
-dontwarn org.slf4j.impl.StaticLoggerBinder
-dontwarn org.xbill.DNS.spi.DnsjavaInetAddressResolverProvider
-dontwarn sun.net.spi.nameservice.NameServiceDescriptor
-dontwarn lombok.Generated

I am not familiar with R8 proguard rules, should I just add dontwarn if the app works normally in my use? Check the builds here.

Yes add these rules.

-dontwarn lombok.Generated
-dontwarn org.slf4j.impl.StaticLoggerBinder
-dontwarn org.xbill.DNS.spi.DnsjavaInetAddressResolverProvider
-dontwarn sun.net.spi.nameservice.NameServiceDescriptor

[AaronChen0]

Build successfully and work in my phones. Please review.

Thanks! And be patient while I download rust. :)
