Some of the key changes listed by Google include:Permissions changes
- The android.permission.USE_FINGERPRINT permission now has "normal" protection level, so it is no longer necessary to request this permission directly from the user. The USE_FINGERPRINT permission enables fingerprints to be enabled for authentication, but does not give the requesting app access to the enrollment/fingerprint administration flow.
- The android.permission.WRITE_EXTERNAL_STORAGE permission has protection level "dangerous", meaning that apps wanting to write to external storage will need to request permission from the user at runtime. Both WRITE_EXTERNAL_STORAGE and WRITE_EXTERNAL_STORAGE are members of the STORAGE permission group.
- Remote Bluetooth/Wi-Fi MAC's now require either the android.permission.LOCATION_FINE or android.permission.LOCATION_COURSE permission.
- Some accounts and identity permissions are moved to CONTACTS permissions group and others are removed or granted based on account type. In particular, android.permission.USE_CREDENTIALS, android.permission.MANAGE_ACCOUNTS, and android.permission.AUTHENTICATE_ACCOUNTS are ungrouped pending further changes in a later release.
- The Wi-Fi permissions android.permission.CHANGE_WIFI_STATE, android.permission.CHANGE_WIMAX_STATE, and android.permission.CHANGE_WIFI_MULTICAST_STATE now have protection level "normal".
- The Bluetooth permissions android.permission.BLUETOOTH and android.permission.BLUETOOTH_ADMIN now have protection level "normal".
- Bookmarks and subscribed feeds permissions are removed.
- Apps included in the system image are no longer granted dangerous permissions automatically. All apps should check for and request permissions at runtime.
- Introduces the utility method Activity.should Show Request Permission Rationale(String), which lets your app see whether users have previously rejected a permission request. This lets you know that your app should explain the the user why it needs that permission. For more information see the Permissions developer guide.
Other changes
- The android.app.AssistContent and android.app.AssistStructure classes are moved into a new package, android.app.assist.
- Bluetooth Stylus APIs are updated and include new callback events. The View.On Stylus Button Press Listener class is renamed to View.On Context Click Listener and GestureDetector.On Stylus Button Press Listener class to Gesture Detector.On Context Click Listener.
