[enhancement]add 64bit version

[chenshaoju]

Current cloak-android only has a 32-bit version, in some cases, the newest phone maybe not support it. [The Pixel 7 series might be the first 64-bit-only Android phones]

and some phones may show a warning message:

Thanks for your hard work.

Hi. Downloaded today, and cannot install this app. Is it possible to create a 64 bit version?
Pixel 7 Pro.

Same here. I am wondering about the effort of migrating to 64 bit. Will build with 64 bit sdk but no code change work?

I am changed ROM, installed custom rom for my phone. Problem with 32bit solved.

Yes, I can install the x86 version, but there are some problems when launching the shadowsocks client with cloak plugin. Every time I have to manually open the cloak plugin then return to shadowsocks client (this leaves the cloak plugin running in the background), otherwise, the shadowsocks client won't start. It will complain "unknown plugin cloak". I suspect it is due to the compatibility problems of x86 version app.

I can see that the build script already compiles the arm64 version apk:

Cloak-android/app/src/make.sh

Line 122 in 08ad33d

echo "Cross compiling ckclient for arm64"

. I think the owner can directly put the artifact to release page?

[bingzhangdai]

These android-strip tools are removed from NDK so that the cross platform compile fails.

Cloak-android/app/src/make.sh

Line 96 in 08ad33d

ANDROID_ARM64_STRIP=$ANDROID_PREBUILT_TOOLCHAIN/bin/aarch64-linux-android-strip

I commented these strip steps and manually built the apk. I can get the x64 version.

However, "unknown plugin ck-client" is still there.

x86_64, arm, and arm64 versions of the native Go lib are included in every APK, so this shouldn't have been the issue.

I was not aware of APKs being architecture specific, I'll look into this.

[bingzhangdai]

@cbeuw This line failed

Cloak-android/app/src/make.sh

Line 124 in 08ad33d

try "$ANDROID_ARM64_STRIP" ck-client

Commented these strip steps will work.
I suggest adding set -e in the beginning of the script to force this build step to fail in Azure DevOps. Then you can notice the error.

[cbeuw]

This alone wouldn't fix the 32-bit APK issue, since existing releases were built successfully when NPK didn't remove strip

[bingzhangdai]

Yes. I tried you project in Azure DevOps build. Actually your cross platform compile does fail.

You can add set -e in the beginning or simply use && between these commands

[cbeuw]

Ah yes you are right, it's been failing the whole time...

I'll fix the build script and make a new release

[bingzhangdai]

btw, I found the solution to "unknown plugin": shadowsocks/shadowsocks-android#1428. It is not related to the x64 bit version.

@cbeuw Thank you. Another request, could you upload it to the play store? It will be more convenient, and the cellphone won't prompt the warning during installation.
