1. Demystify Android Permission By : Chintan Rathod
2. What is permission?
3. How permission works? Install an App List of Permissions in Androidmenifest.xml Ask user for approval User approve ? System cancels installation Denies all permissions System installs application Grants all permissions
4. Current approach
5. What we are doing? • We put trust on them • Also granting permission which are not necessary but there is no other way around
6. What’s new? • Each app will run in limited sandbox • Explicit permission request is required for outside resource use • User may grant or deny runtime permission
7. Level of protections new? Normal Permission It cover areas where your app needs to access data or resources outside the app's sandbox, but where there's very little risk to the user's privacy or the operation of other apps Dangerous Permission It cover areas where the app wants data or resources that involve the user's private information, or could potentially affect the user's stored data or the operation of other apps.
