Claude Code hangs on startup in Termux (Android) with Node.js v24

Environment

• Platform: Termux on Android (Samsung S24 Ultra)
• Node.js: v24.x (installed via pkg)
• Claude Code: Latest from npm

Description

Claude Code hangs for 60+ seconds on startup in Termux. Debug logs show the process stalls between configureGlobalAgents complete and any subsequent activity.

Steps to Reproduce

1. Install Termux on Android
2. pkg install nodejs-lts (installs Node v24)
3. npm install -g @anthropic-ai/claude-code
4. Run claude - hangs with no output

Debug Output

[DEBUG] Starting CLI...
[DEBUG] configureGlobalAgents complete
# 60+ second gap here
[DEBUG] ... eventually continues or times out

Investigation Done

• Network connectivity confirmed working (curl to api.anthropic.com succeeds)
• --no-update-check flag doesn't help
• ANTHROPIC_TIMEOUT environment variable doesn't help
• Issue appears to be in initialization, possibly:
• Keytar/credential storage not available on Android
• Native module compatibility with Node v24 on Android/ARM

Workaround

Created HTTP proxy through a Linux server where Claude Code works normally:

# On working server
app.post('/api/claude/run', (req, res) => {
  exec(`echo '${prompt}' | claude`, ...);
});

# On phone
curl -X POST server:3030/api/claude/run -d '{"prompt":"..."}'

Expected Behavior

Claude Code should start and reach the interactive prompt within a few seconds.

Additional Context

This may be related to Node.js v24 specifically, or to missing native dependencies in Termux's sandboxed environment.
