build your own android aar lib or else will lookup failed #26

weishirongzhen · 2021-09-15T07:38:20Z

Because official lib build flag in CmakeLists.txt set(CMAKE_CXX_VISIBILITY_PRESET hidden), that will cause android exception when dart ffi lookup function.

Please refer to My other repo to run full demo,
also, replace you own build to ensure safety.
build step: follow Official build step to prepare your build env , then change

 set(CMAKE_CXX_VISIBILITY_PRESET hidden)

to

 set(CMAKE_CXX_VISIBILITY_PRESET default)

build project, replace your own output in My other repo.

Now Android Lib are extract to github package.

repositories {
        google()
        jcenter()
        maven {
            url = uri("https://maven.pkg.github.com/weishirongzhen/wallet-core")
            credentials {
                username = "weishirongzhen"
                password = "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" // GH token for only allow read package
            }
        }
    }

then

implementation "com.weishirongzhen:wallet-core:2.6.20"

How to build the android lib or ios framework from the trust wallet core, what should we modify the code of trust wallet core repo to build succesful for flutter, thank you.

How to build the android lib or ios framework from the trust wallet core, what we should modify the code of trust wallet core repo to build succesful for flutter, thank you.

build step please refer to this link https://developer.trustwallet.com/wallet-core/developing-the-library/building

and for android, only need to do is modify CMakeLists.txt and

change set(CMAKE_CXX_VISIBILITY_PRESET hidden) to set(CMAKE_CXX_VISIBILITY_PRESET default)

How to connect to network?

weishirongzhen · 2021-10-18T01:30:26Z

How to connect to network?

wallet-core only handle local things, create wallet, sign transaction etc, your can broadcast your sign output to any network you like.

RayOkaah · 2021-10-18T01:32:57Z

Thanks. Please point me to any resource I can read up on broadcasting on a network. Thanks for the work.

sylvestrevgen · 2021-11-22T12:48:52Z

Hello. How can I use this package? I ask this, cause before, you wrote in README that we need to build trustwallet core and move to flutter plugin. But now, you removed this steps from README.md. So, I can clone this repo and just use without any building?

weishirongzhen · 2021-11-22T12:51:52Z

yes， if you want to use in your own project
just add this in your yaml

 flutter_trust_wallet_core:
    git:
      url: https://github.com/weishirongzhen/flutter_trust_wallet_core_lib_include.git

sylvestrevgen · 2021-11-22T12:58:52Z

Okay. But how it works? We are building our wallet app and цe're worried about security. Cause we don't know what is inside android and ios builds. Maybe, mining?)) Sorry, it is joke. But we are a little worried.

sylvestrevgen · 2021-11-22T12:59:28Z

But you have done an excellent work and we really want to use your plugin.

weishirongzhen · 2021-11-22T13:01:52Z

if you are worry , you can build your own lib to use.
for android only need to change CMakeList.txt line 14 , from "hidden" to "default", and follow the official build step.
for iOS, nothing need to change, just follow the official build step.
and then replace your lib in to project.

sylvestrevgen · 2021-11-22T13:14:37Z

So, for our own builds, we need just move android build to android/libs/....aar, and ios - ios/frameworks/...? Thats all?

weishirongzhen · 2021-11-22T13:16:07Z

yep, that's all you need to do

sylvestrevgen · 2021-11-22T13:17:47Z

Understood, thank you so much for information. And thank you for all your work. Please, keep going your excellent work.

weishirongzhen · 2021-11-22T13:21:29Z

Understood, thank you so much for information. And thank you for all your work. Please, keep going your excellent work.

Thanks, there still are lots of code to do, I'm busy at other flutter project, this project are quite slow progress, but will keep update.

@weishirongzhen Do you know why does it only affect the android build?

好的，多谢。可以帮看看这个问题吗？
trustwallet/wallet-core#3319

我根据官方文档构建出来的 WalletCore.xcframework, 没办法解密keystore，但是官方直接提供的可以解密，是不是我哪个步骤走错了？最后 WalletCore.xcframework 是从 swift/build/WalletCore.xcframework 取的。 @weishirongzhen

@weishirongzhen
my build command is:

./tools/install-dependencies
./tools/install-rust-dependencies
./tools/install-wasm-dependencies

./tools/generate-files ios
cmake -H. -Bbuild -DCMAKE_BUILD_TYPE=Debug
 make -Cbuild && ./tools/ios-build && ./tools/ios-xcframework

then i got

./swift/build/WalletCore.xcframework/
./swift/build/SwiftProtobuf.xcframework/

then i import WalletCore.xcframework & SwiftProtobuf.xcframework to my ios project, all code is:

//
//  ContentView.swift
//  wallet
//
//

import SwiftUI
import WalletCore
struct ContentView: View {
    var json = """
                {"crypto":{"cipher":"aes-128-ctr","cipherparams":{"iv":"5fe1054ca4ca68c5f8ee1346cd062239"},"ciphertext":"ae7db4237ec6913241dcf7bcfb6e06671ae381906a2866b04771082ed0204ac4","kdf":"scrypt","kdfparams":{"dklen":32,"n":16384,"p":4,"r":8,"salt":""},"mac":"9ed6e105ebcc39ba38706166a24f03ebfa153fc41bc028418dafb08518d6ebae"},"id":"b4c58a86-f609-4c12-88bd-666cc2ee73be","name":"name","type":"private-key","version":3}
""";
    var body: some View {
        
        VStack {
            Image(systemName: "globe")
                .imageScale(.large)
                .foregroundColor(.accentColor)
            Text("Hello, world!")
            Button("click") {
                
         
                print(SegwitAddress.isValidString(string: "bc1qyd9ky0n2dh8nggk8m4thllh0qh0w2ea2asvtl5"))
                print(SegwitAddress.isValidString(string: "1CFx8Qvd3ioDHYWHJMSMNeredCCkW96wAA"))
                let storedKey = StoredKey.importJSON(json: json.data(using: String.Encoding.utf8)!)!
             
                let privatekey = storedKey.decryptPrivateKey(password: "password".data(using: String.Encoding.utf8)!)
                
                
                print(privatekey?.hexString)
            }
        }
        .padding()
    }
}

struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView()
    }
}

then i click click, i can not decrypt keystore, privateKeyHex is nil.
but when i use official package, i can decrypt then same keystore, so , is there have some problem about my build flow?

weishirongzhen · 2023-07-26T01:29:07Z

I think you can try with below two step

./bootstrap.sh
./tools/ios-xcframework

then copy new WalletCore.xcframework and SwiftProtobuf.xcframework to you project

weixuefeng · 2023-07-26T13:35:12Z

i got nil too... Did you make it? @weishirongzhen
