Missing x86_64 folder in ./app/src/main/cpp/*/lib with lib*.a files & Instructions to reproduce binaries in lib folders

[emanuelb]

building the app from tag v0.32.6 fail with error:

ninja: error: '/home/appuser/app/mixin/android-app/app/src/main/cpp/opus/lib/x86_64/libopusenc.a', needed by '/home/appuser/app/mixin/android-app/app/build/intermediates/cxx/RelWithDebInfo/5h42116x/obj/x86_64/libmixin.so', missing and no known rule

this happen even on alpine when installing libopusenc-dev

Containerfile debian based to reproduce:

These libraries can be compiled from https://github.com/xiph/opus https://github.com/xiph/ogg https://github.com/xiph/libopusenc

[emanuelb]

The problem is that in directory: https://github.com/MixinNetwork/android-app/tree/master/app/src/main/cpp/opus/lib There only folders:

arm64-v8a/ armeabi-v7a/ x86/

That contain files:

libogg.a libopus.a libopusenc.a

But no folder x86_64 that also need to contain above files.

Also script to re-create (by compiling) above files is needed, how they was compiled or from where they was downloaded, they can be downloaded from: https://pkgs.alpinelinux.org/package/edge/community/x86_64/libopusenc-dev https://pkgs.alpinelinux.org/package/edge/main/x86_64/opus-dev https://pkgs.alpinelinux.org/package/edge/main/x86_64/libogg-dev https://pkgs.alpinelinux.org/package/edge/main/x86_64/lz4-static and also needed the file: ./app/src/main/cpp/rlottie/lib/x86_64/librlottie_internal.a

@crossle Should we add x86_64 support to the project ?

It's ok to support x86_64, we publish on google play use app bundle. but the universal apk will be bigger than before.

Workaround for this issue is to run commands before ./gradlew assembleRelease that will build release variant:

keytool -genkey -alias mixin_alias -keystore app/mixin.pfx -storetype PKCS12 -keyalg RSA -keysize 4096 -storepass mixin_alias -keypass mixin_alias -validity 10000 -dname CN=IL; \
printf "\nRELEASE_STORE_FILE=mixin.pfx\nRELEASE_STORE_PASSWORD=mixin_alias\nRELEASE_KEY_PASSWORD=mixin_alias\nRELEASE_KEY_ALIAS=mixin_alias\n" >> gradle.properties;

as the code will build release variant only if RELEASE_STORE_FILE is specified (even when using assembleRelease it's not enough) which use different abiFilters without x86 that cause the build failure in this issue (affect debug variant) https://github.com/MixinNetwork/android-app/blob/59d13898f079e73140b571a5b79bcebbef4f5440/app/build.gradle#L144-L156
