## How to build

### Install OpenJDK 11+, g++, rename (used for building modules), gradle 5.1+
```bash
sudo apt-get install g++ rename openjdk-11-jdk gradle
```

If your system provides gradle with version < 5.1, download it from gradle homepage:

https://gradle.org/install/

### Download and prepare Android SDK for building
Android SDK Available here:

https://developer.android.com/studio#downloads

Download Android SDK, unpack it to temporary directory `/tmp/anrdoid-sdk` and install it (in `/opt/android-sdk` for example) with required packages
```bash
mkdir /tmp/android-sdk
cd /tmp/android-sdk
wget https://dl.google.com/android/repository/commandlinetools-linux-8092744_latest.zip
unzip commandlinetools-linux-8092744_latest.zip
# install required tools
./cmdline-tools/bin/sdkmanager --sdk_root=/opt/android-sdk "build-tools;31.0.0" "cmake;3.18.1" "ndk;21.4.7075529"
```

### Clone repository with submodules

git clone --recurse-submodules https://github.com/PurpleI2P/i2pd-android.git
```
