| # Building mobile libraries | ||
|
|
||
| ## Prerequisites | ||
|
|
||
| To build for iOS, you need to run macOS with either | ||
| [Command Line Tools](https://developer.apple.com/download/all/?q=command%20line%20tools) | ||
| or [Xcode](https://apps.apple.com/app/xcode/id497799835) installed. | ||
|
|
||
| To build for Android, you need either | ||
| [Android Studio](https://developer.android.com/studio) or | ||
| [Command Line Tools](https://developer.android.com/studio#downloads) installed, which in turn must be used to install [Android NDK](https://developer.android.com/ndk/). | ||
|
|
||
|
|
||
| ### Go and Go mobile | ||
|
|
||
| First, follow the instructions to [install Go](https://github.com/lightningnetwork/lnd/blob/master/docs/INSTALL.md#building-a-development-version-from-source). | ||
|
|
||
| Then, install [Go mobile](https://github.com/golang/go/wiki/Mobile) and | ||
| initialize it: | ||
|
|
||
| ```shell | ||
| ⛰ go install golang.org/x/mobile/cmd/gomobile@latest | ||
| ⛰ go mod download golang.org/x/mobile | ||
| ⛰ gomobile init | ||
| ``` | ||
|
|
||
| ### Docker | ||
|
|
||
| Install and run [Docker](https://www.docker.com/products/docker-desktop). | ||
|
|
||
| ### Make | ||
|
|
||
| Check that `make` is available by running the following command without errors: | ||
|
|
||
| ```shell | ||
| ⛰ make --version | ||
| ``` | ||
|
|
||
| ## Building the libraries | ||
|
|
||
| Note that `gomobile` only supports building projects from `$GOPATH` at this | ||
| point. However, with the introduction of Go modules, the source code files are | ||
| no longer installed there by default. | ||
|
|
||
| To be able to do so, we must turn off module and using the now deprecated | ||
| `go get` command before turning modules back on again. | ||
|
|
||
| ```shell | ||
| ⛰ go env -w GO111MODULE="off" | ||
| ⛰ go get github.com/lightninglabs/lightning-terminal | ||
| ⛰ go get golang.org/x/mobile/bind | ||
| ⛰ go env -w GO111MODULE="on" | ||
| ``` | ||
|
|
||
| Finally, let’s change directory to the newly created lightning-terminal folder inside `$GOPATH`: | ||
|
|
||
| ```shell | ||
| ⛰ cd $GOPATH/src/github.com/lightninglabs/lightning-terminal | ||
| ``` | ||
|
|
||
| It is not recommended building from the master branch for mainnet. To checkout | ||
| the latest tagged release of Lightning Terminal, run | ||
|
|
||
| ```shell | ||
| ⛰ git checkout $(git describe --match "v[0-9]*" --abbrev=0) | ||
| ``` | ||
|
|
||
| ### iOS | ||
|
|
||
| ```shell | ||
| ⛰ make ios | ||
| ``` | ||
|
|
||
| The Xcode framework file will be found in `mobile/build/ios/Litdmobile.xcframework`. | ||
|
|
||
| ### Android | ||
|
|
||
| ```shell | ||
| ⛰ make android | ||
| ``` | ||
|
|
||
| The AAR library file will be found in `mobile/build/android/Litdmobile.aar`. | ||
|
|
||
| --- | ||
| Tip: `make mobile` will build both iOS and Android libraries. | ||
|
|
||
| --- | ||
|
|
||
| ## Generating proto definitions | ||
|
|
||
| In order to call the methods in the generated library, the serialized proto for | ||
| the given RPC call must be provided. Similarly, the response will be a | ||
| serialized proto. | ||
|
|
||
| ### iOS | ||
|
|
||
| In order to generate protobuf definitions for iOS, add `--swift_out=.` to the | ||
| first `protoc` invocation found in [ `gen_protos.sh` ](../lnrpc/gen_protos.sh). | ||
|
|
||
| Then, some changes to [Dockerfile](../lnrpc/Dockerfile) need to be done in | ||
| order to use the [Swift protobuf](https://github.com/apple/swift-protobuf) | ||
| plugin with protoc: | ||
|
|
||
| 1. Replace the base image with `FROM swift:focal` so that Swift can be used. | ||
| 2. `clang-format='1:7.0*'` is unavailable in Ubuntu Focal. Change that to | ||
| `clang-format='1:10.0*'`. | ||
| 3. On the next line, install Go and set the environment variables by adding the | ||
| following commands: | ||
|
|
||
| ``` | ||
| RUN apt-get install -y wget \ | ||
| && wget -c https://golang.org/dl/go1.17.6.linux-amd64.tar.gz -O - \ | ||
| | tar -xz -C /usr/local | ||
| ENV GOPATH=/go | ||
| ENV PATH=$PATH:/usr/local/go/bin:/go/bin | ||
| ``` | ||
|
|
||
| 4. At the end of the file, just above `CMD`, add the following `RUN` command. | ||
| This will download and compile the latest tagged release of Swift protobuf. | ||
|
|
||
| ``` | ||
| RUN git clone https://github.com/apple/swift-protobuf.git \ | ||
| && cd swift-protobuf \ | ||
| && git checkout $(git describe --tags --abbrev=0) \ | ||
| && swift build -c release \ | ||
| && mv .build/release/protoc-gen-swift /bin | ||
| ``` | ||
|
|
||
| Finally, run `make rpc`. | ||
|
|
||
| Tip: The generated Swift files will be found in various folders. If you’d like | ||
| to move them to the same folder as the framework file, run | ||
|
|
||
| ```shell | ||
| ⛰ find . -name "*.swift" -print0 | xargs -0 -I {} mv {} mobile/build/ios | ||
| ``` | ||
|
|
||
| `Litdmobile.xcframework` and all Swift files should now be added to your Xcode | ||
| project. You will also need to add [Swift Protobuf](https://github.com/apple/swift-protobuf) | ||
| to your project to support the generated code. | ||
|
|
||
| ### Android | ||
|
|
||
| #### First option: | ||
|
|
||
| In order to generate protobuf definitions for Android, add `--java_out=.` | ||
|
|
||
| to the first `protoc` invocation found in | ||
| [ `gen_protos.sh` ](../lnrpc/gen_protos.sh). Then, run `make rpc`. | ||
|
|
||
|
|
||
| #### Second option (preferable): | ||
|
|
||
| - You have to install the profobuf plugin to your Android application. | ||
| Please, follow this link https://github.com/google/protobuf-gradle-plugin. | ||
| - Add this line to your `app build.gradle` file. | ||
| ```shell | ||
| classpath "com.google.protobuf:protobuf-gradle-plugin:0.8.17" | ||
| ``` | ||
| - Create a `proto` folder under the `main` folder. | ||
|
|
||
|  | ||
|
|
||
| - Add `aar` file to libs folder. | ||
|
|
||
| - After that add these lines to your `module's` `build.gradle` file: | ||
|
|
||
| ```shell | ||
| plugins { | ||
| id "com.google.protobuf" | ||
| } | ||
|
|
||
| android { | ||
| sourceSets { | ||
| main { | ||
| proto { | ||
|
|
||
| } | ||
| } | ||
| } | ||
| } | ||
|
|
||
| dependencies { | ||
| implementation fileTree(dir: "libs", include: ["*.jar"]) | ||
| implementation "com.google.protobuf:protobuf-javalite:${rootProject.ext.javalite_version}" | ||
| } | ||
|
|
||
| protobuf { | ||
| protoc { | ||
| artifact = "com.google.protobuf:protoc:${rootProject.ext.protoc_version}" | ||
| } | ||
| generateProtoTasks { | ||
| all().each { task -> | ||
| task.builtins { | ||
| java { | ||
| option "lite" | ||
| } | ||
| } | ||
| } | ||
| } | ||
| } | ||
| ``` | ||
| - Then, copy all the proto files from `lnd/lnrpc` to your `proto` folder, saving the structure. | ||
| - Build the project and wait until you see the generated Java proto files in the `build` folder. | ||
|
|
||
|
|
||
| --- | ||
| *Note:* | ||
|
|
||
| If Android Studio tells you that the `aar` file cannot be included into the `app-bundle`, this is a workaround: | ||
|
|
||
| 1. Create a separate gradle module | ||
| 2. Remove everything from there and leave only `aar` and `build.gradle`. | ||
|
|
||
|  | ||
|
|
||
| 3. Gradle file should contain only these lines: | ||
|
|
||
| ```shell | ||
| configurations.maybeCreate("default") | ||
| artifacts.add("default", file('Litdmobile.aar')) | ||
| ``` | ||
|
|
||
| 4. In `dependencies` add this line instead of depending on `libs` folder: | ||
| ```shell | ||
| implementation project(":litdmobile", { "default" }) | ||
| ``` | ||
| --- | ||
| ## Calling the API | ||
| In LND v0.15+ all API methods have prefixed the generated methods with the subserver name. This is required to support subservers with name conflicts. | ||
| eg. `QueryScores` is now `AutopilotQueryScores`. `GetBlockHeader` is now `NeutrinoKitGetBlockHeader`. | ||
