2. I  am… • Shintaro  Katafuchi   • GitHub:  hotchemi   • Recruit  Technologies  Co.,Ltd.   • Scrum  Engineering  Group   • kyobashi.dex  ←  Now!!!
3. Runtime  Permissions
4. Before
6. After
8. Runtime  Permissions • From  Marshmallow   • User  can  manage  permissions  at  runtime   • User  can  revoke  permissions  from  setting   • Showing  dialog  →  targeted  M  app   • From  setting  →  even  not  targeted  M  app
9. Other  stuff… • Permission  groups   • ex)  android.permission-­‐group.CALENDAR   • android.permission.READ_CALENDAR   • android.permission.WRITE_CALENDAR   • shouldShowRequestPermissionRationale…?   • A  ton  of  support  library  methods…   • Activity,  ActivityCompat,  PermissionChcker,  ContextCompat,  Fragment,  FragmentCompat…
