- 23. 相容性 ● 需要檢查 Build.VERSION_CODE< 23 ● 或是使用 Support v4
- 24.
- 25. 一般時機 ● 需要時再要求(map, 定位...) ●永遠不要有預設立場，在onCreate檢查 ● 發送 Intent 時也需要權限
- 26. Service? 1. 一開APP 馬上要求權限 2.需要時發出Notification 3. 隨時提醒使用者
- 27.
- 28. 建議 ● 盡量隔離外部資源 ● PermissionAPI再包裝一層
- 29.
- 30. 偷偷被藏起來的權限... ● Manifest.permission.WRITE_SETTINGS ● Manifest.permission.CHANGE_NETWORK_STATE ●Manifest.permission.SYSTEM_ALERT_WINDOW
- 31. pre23| preinstalled permissions ●Android M 之後預設無法使用 ● Manifest.permission.WRITE_SETTINGS 可以經由 intent ACTION_MANAGE_WRITE_SETTINGS 開啟
