+
+## Ubuntu方案
+
+- 首先安装依赖包：
+
+```bash
+sudo apt install openjdk-17-jdk nodejs
+```
+
+- 安装Command-tools：
+
+```bash
+mkdir -p ~/Android/cmdline-tools/latest
+## 下载链接：https://developer.android.com/studio?hl=zh-cn#command-tools
+cd ~/Android/cmdline-tools/latest
+wget https://dl.google.com/android/repository/commandlinetools-linux-13114758_latest.zip
+unzip ./commandlinetools-linux-13114758_latest.zip
+```
+
+- 使用官方脚本安装Sdkman包管理器：
+
+```bash
+curl -s "https://get.sdkman.io" | bash
+source "$HOME/.sdkman/bin/sdkman-init.sh"
+```
+
+- 随后使用Sdkman下载并安装gradle/kotlin：
+
+```bash
+sdk install gradle
+sdk install kotlin
+```
+
+- 设置环境变量：
+```bash
+export ANDROID_HOME=$HOME/Android
+export PATH=$PATH:$ANDROID_HOME/emulator
+export PATH=$PATH:$ANDROID_HOME/platform-tools
+export PATH=$PATH:$ANDROID_HOME/cmdline-tools/latest/bin
+export PATH=$PATH:$ANDROID_HOME/build-tools/34.0.0
+source ~/.bashrc
+```
+
+- 继续下载一些SDK平台与构建工具：
+
+```bash
+sdkmanager "platforms;android-34" "build-tools;34.0.0" "platform-tools"
+sdkmanager "emulator"   //虚拟机中调试
+```
+
+- 查看版本
+
+```bash
+(base) dich@uos:~$ sdk version
+
+SDKMAN!
+script: 5.20.0
+native: 0.7.14 (linux x86_64)
+
+(base) dich@uos:~$ gradle -v

+
+## Key方案
+
+构建Release包需要密钥签名验证，可以使用传统的明文配置或者使用密钥管理器.
+
+### 相同部分
+
+- 生成密钥
+```bash
+keytool -genkey -v \
+  -keystore ~/.android/jetlagged-release.keystore \
+  -alias jetlagged \
+  -keyalg RSA \
+  -keysize 2048 \
+  -validity 10000
+```
+
+- 修改app/build.gradle.kts
+```bash
+    signingConfigs {
+        create("release") {
+            storeFile = System.getenv("KEYSTORE_FILE")?.let { file(it) }
+            storePassword = System.getenv("KEYSTORE_PASSWORD")
+            keyAlias = System.getenv("KEY_ALIAS")
+            keyPassword = System.getenv("KEY_PASSWORD")
+        }
+    }
+
+    buildTypes {
+        release {
+            signingConfig = signingConfigs.getByName("release")  // 添加这行
+            isMinifyEnabled = true
+            proguardFiles(
+                getDefaultProguardFile("proguard-android-optimize.txt"),
+                "proguard-rules.pro"
+            )
+        }
+    }
+```
+### 传统方法
+
+- 创建配置文件
+```bash
+cat > ~/.android-signing-secrets << 'EOF'
+export KEYSTORE_FILE="$HOME/.android/jetlagged-release.keystore"
+export KEYSTORE_PASSWORD="你的keystore密码"
+export KEY_ALIAS="jetlagged"
+export KEY_PASSWORD="你的key密码"
+EOF
+
+# 设置权限
+chmod 600 ~/.android-signing-secrets
+
+# 添加到 gitignore (全局)
+echo ".android-signing-secrets" >> ~/.gitignore_global
+```
+
+- flake配置
+
+```bash
+# Auto load Key
+if [ -f "$HOME/.android-signing-secrets" ]; then
+    source "$HOME/.android-signing-secrets"
+    echo "KeyOK"
+fi
+```
+
+### 现代方法
+
+- 安装libsecret包
+- keepassxc新建Android群组，添加条目``android_key_password``和``android_keystore_password``；
+- 设置密码，和上面生成的相同；
+- 在条目的高级-属性中添加``name/android_key_password``和``name/android_keystore_password``；
+- 打开设置-保密服务集成，公开Android文件夹
+- flake中写
+
+```bash         
+# Release Key
+export KEYSTORE_FILE="$HOME/.android/jetlagged-release.keystore"
+export KEY_ALIAS="jetlagged"
+export KEYSTORE_PASSWORD="$(secret-tool lookup name android_keystore_password)"
+export KEY_PASSWORD="$(secret-tool lookup name android_key_password)"
+```
+---
+**Done.**
