Feishu/Lark CLI Setup on Android/Termux

Installation

# Download latest release for linux-arm64

Known Issue: DNS Resolution on Android/Termux

Symptom: lark auth login fails with:

dial tcp: lookup accounts.feishu.cn on [::1]:53: read udp [::1]:xxxxx->[::1]:53: read: connection refused

Root Cause: Go's net resolver defaults to [::1]:53 on Android, which is not available.

Workaround: Use direct API calls with tenant_access_token instead of OAuth device flow.

Direct API Authentication (Workaround)

# Get tenant_access_token directly
curl -s -X POST https://open.feishu.cn/open-apis/auth/v3/tenant_access_token/internal \
  -H "Content-Type: application/json" \
  -d '{"app_id":"YOUR_APP_ID","app_secret":"YOUR_APP_SECRET"}'

Response:

{"code":0,"expire":7200,"msg":"ok","tenant_access_token":"t-xxxxxxxx"}

Using lark-cli with Token File

When OAuth fails, create token file manually:

# Get token via curl, then create lark-cli config
mkdir -p ~/.lark-cli/hermes
echo '{"app_id":"cli_xxx","tenant_access_token":"t-xxx"}' > ~/.lark-cli/hermes/config.json
