Add Compile scripts for libs

[6543]

just some idears/thoughts for #45 and #5

[6543]

@Gedsh would be nice if you reveal me how you compile the localy :)

PS: you have write access to my fork if you accept the infitation (just in case it is usefull ...)

You can build Golang binaries (dnscrypt, obfs4proxy, snowflake) for android as shown below. Go compiler and Android NDK required. I am using dnscrypt as an example.

#armv7a:

$env:GOPATH=c:\Go\bin\go.exe
$env:GOOS='android'
$env:GOARCH='arm'
$NDK="C:\Users\Alexander\AppData\Local\Android\Sdk\ndk-bundle"
$env:Path += ";$NDK/toolchains/llvm/prebuilt/windows-x86_64/bin"
$env:CCX="$NDK/toolchains/llvm/prebuilt/windows-x86_64/bin/armv7a-linux-androideabi16-clang++"
$env:CC="$NDK/toolchains/llvm/prebuilt/windows-x86_64/bin/armv7a-linux-androideabi16-clang"
$env:CGO_ENABLED=1

#arm64:

$env:GOPATH=c:\Go\bin\go.exe
$env:GOOS='android'
$env:GOARCH='arm64'
$NDK="C:\Users\Alexander\AppData\Local\Android\Sdk\ndk-bundle"
$env:Path += ";$NDK/toolchains/llvm/prebuilt/windows-x86_64/bin"
$env:CCX="$NDK/toolchains/llvm/prebuilt/windows-x86_64/bin/aarch64-linux-android29-clang++"
$env:CC="$NDK/toolchains/llvm/prebuilt/windows-x86_64/bin/aarch64-linux-android29-clang"
$env:CGO_ENABLED=1

#common:

cd C:\Go\My\dnscrypt-proxy-2.0.44\dnscrypt-proxy
go clean
go build -ldflags="-s -w" -o $env:GOPATH/android/dnscrypt-proxy

To build Purple I2P Android NDK is required. I use android-ndk-r14b for this.

Change the path to libraries in this file https://github.com/PurpleI2P/i2pd/blob/openssl/android_binary_only/jni/Application.mk
I am using PowerShell.

cd C:\Users\Alexander\AppData\Local\Android\Sdk\ndk\android-ndk-r14b
"ndk-build -C C:\i2pd-opensslv2.33.0\android_binary_only -j" | cmd

Thank you. But unfortunately I have no experience with compile scripts.

[6543]

ok now https://github.com/PurpleI2P/i2pd and https://github.com/guardianproject/gpmaven/tree/master/org/torproject/tor-android-binary are missing only ...

go libs can now be compiled automaticaly by this scritp :)

wip ...

Tor for Android https://github.com/guardianproject/tor-android

go libs can now be compiled automaticaly by this scritp :)

Cool!

Added a script for building Tor for Android from source using Gitlab CI / CD https://github.com/Gedsh/Tor-Android-build-script

[6543]

thanks will add it :)

Based on your great work, I manage to build it with f-droid's gitlab CI but there are some problems. I'm not a dev and have little knowledge about Android. Could you please take a look?
log
apk file
build.sh
fdroid metadata
It seems that the dnscrypt and i2pd work but tor can't start. Maybe ithe reason is that due to the space limitation of gitlab ci I didn't install ndk r20 and r20b so everything is build by r21d. My fault, should be fixed now. Works well on my device. The icon is the beta one, I don't know why.
Thanks!

@6543 Are you still working on this? Would you please take some time to complete this pr? Or I can make another one based on this.

@Gedsh I have some questions. Due to my poor knowledge maybe they are stupid. Could you please help me?

• How does the version of i2pd specified? I didn't find it.
• APP_ABI for tor is armeabi while for i2pd is armeabi-v7a. Is this intended? In i2pd's makefile the APP_ABI is armeabi but in gitlab ci armeabi-v7a is passed. What's the difference?
• Would you like to include two arches in F-Droid? Then autoupdate won't work so that a mr is needed when a new version is available.
• tor for android is available in F-Droid's trusted repo. Is it possible to use that?

Thanks!

@linsui feel free to use this pull to finish the work, I have no time to finish it at the moment. So If you like tho have it soon you should pick this up and finish it ;)

[6543]

@linsui I have invited you to my fork: https://github.com/6543-forks/InviZible/invitations so feel free to push to this branch or create a new one based on that from your side ...

[linsui]

@6543 Thanks!

Thank you! Cool job!

Works well on my device.

Great!

The icon is the beta one, I don't know why.

I thought the beta would be used for f-droid. But with @IzzySoft we decided to use the stable version. I will change the icon.

How does the version of i2pd specified? I didn't find it.

It just uses the latest changes. You can use for example:
git clone --single-branch --branch 2.35.0 https://github.com/PurpleI2P/i2pd.git

APP_ABI for tor is armeabi while for i2pd is armeabi-v7a. Is this intended? In i2pd's makefile the APP_ABI is armeabi but in gitlab ci armeabi-v7a is passed. What's the difference?

The difference is in the processor instruction set. Usually modern processors can use armeabi and armeabi-v7a without any problem.
I'm just using build scripts from the Tor and I2P projects with some adaptation. If they listed armabi or armabi-v7a I thought it might be important and just used the same.

Would you like to include two arches in F-Droid? Then autoupdate won't work so that a mr is needed when a new version is available.

I think it is better to include the armv7a version as it works on both armv7a and arm64 devices.

tor for android is available in F-Droid's trusted repo. Is it possible to use that?

If you want to. But I will continue to use my own builds as I like using the Tor beta versions in InviZible.

I would prefer to specify a version when build it or it will produce different resultes on every build.

I got it!

I don't know how the update checker works. @IzzySoft @licaon-kter Could you please help? I got WARNING: ...pan.alexander.tordnscrypt.stable : Couldn't find package ID when running the checkupdates.

[IzzySoft]

@linsui not my speciality, but: what is the name of your *.yml – and what is the packageName in build.gradle? The two must match. Work-around for rare cases: if we package it as pan.alexander.tordnscrypt.stable, the build/flavor produces it that way, but build.gradle has e.g. pan.alexander.tordnscrypt (and the suffix is somehow created during the build), there's a matching keyword for the YAML I just saw today (didn't know before it exists): UpdateCheckName: pan.alexander.tordnscrypt would tell the updater to check for that packageId, regardless of the "final name". Details in our Metadata Reference: UpdateCheckName:

When checking for updates (via UpdateCheckMode) this can be used to specify the package name to search for. Useful when apps have a static package name but change it programmatically in some app flavors, by e.g. appending “.open” or “.free” at the end of the package name.

[linsui]

@IzzySoft Thanks for your tips! I'll test it. The package name does present in the gradle file.

InviZible/tordnscrypt/build.gradle

Line 13 in 9b81113

applicationId "pan.alexander.tordnscrypt.stable"

[IzzySoft]

🤷‍♂️ Maybe it complains because there is no applicationId in the defaultConfig? No idea, I just mentioned what came to mind. I'm not really fit in gradle or Android programming. I can read and understand some things, but that's quite limited 😆

[linsui]

This pr is ready for review. Here is the apk for test. Thanks!
