📝 Notes

Android Notes

• Need to handle runtime permissions for Android 6.0+
• Foreground Service requires notification display
• Battery optimization whitelist requires manual user authorization
• Different manufacturers may have additional restrictions

iOS Notes

• Background Modes require valid use cases
• App Store review may reject long-running background apps
• Need to handle app termination by system
• Some APIs require privacy permission descriptions

General Notes

• Mobile networks are unstable, need robust reconnection mechanism
• Battery consumption is a key metric, requires continuous optimization
• Different device performance varies greatly, need adaptive approach
• Security is important, ensure TLS is properly configured
