Runtime Permissions

Runtime Permissions

● Google Play no longer requests permissions at

installation time

● Users can get into your app quicker than ever

before

● Gives more control and visibility to users

● Permissions are simplified using permission groups

Runtime Permissions

● Permission groups contain multiple

permissions and you can get them at once

● If you add a new permission in a new release

the user doesn’t get blocked by them

● The new permission model enhances the

overall User Experience

Doze and App Standby

Doze and App Standby

● These are two power-saving features that extend battery life

● All apps running on Android 6.0 are affected and should be optimized for them

● These modes manage and restrict the behaviour of apps

Understanding Doze Mode

● When the device is unplugged and stationary for a period of time, with the

screen off, the device enters Doze mode

● This mode suspends access to intensive CPU services, network, jobs, sync

adapters and standard alarms

● Provides a maintenance window where those restrictions are disabled

Understanding Doze Mode

Doze Mode Restrictions

● Network access it suspended

● The system does not allow Sync Adapters to run

● Standard AlarmManager alarms are deferred to the next maintenance window

● If you need to set alarms to fire in Doze

mode use setAndAllowWhileIdle() or setExactAndAllowWhileIdle()

● Alarms set with setAlarmClock() continue to fire normally

● The System does not perform WIFI scans

● The system ignores wake locks

● The system does not allow JobScheduler to run

App Standby

● It allows the system to determine that an app is idle when the user is not

actively using it

● App Standby will automatically put unused apps to sleep. It’s basically

disabled.

App Standby

● If the device is idle for long periods of time, the system allow idle apps network

access around once a day

● In standby mode, network access is disabled, and syncs and scheduled jobs

all get shut down. The app won't be able to run any background services

● When the device is plugged, the system releases apps from the standby state

Direct Share

● Provides a direct way of sharing content with your contacts no matter which app they are from

● Improves the share user experience providing a better integration across different apps

● It allows the user to share content directly into another app

● It’s a service that extends ChooserTargetService

Fingerprint Authentication

Juan Pablo Proverbiohttps://nz.linkedin.com/in/proverbio

● Now apps can access the fingerprint hardware. You can also implement your own UI, but you should use the standard fingerprint icon

● Provides a better User Experience because it doesn’t require the user to remember and enter a password or pin

● It’s a good option for signing in, completion of a sensitive operation like buy an item or settings changes, etc.

● The related permission is<uses-permission android:name="android.permission.USE_FINGERPRINT" />

Auto Backup for Apps

Auto Backup for Apps

● The system now performs automatic full data backup and restore for apps

● Your app must target API level 23 to enable this feature

● Auto data backup allows to save user data even when the app is uninstalled from a device

● Enhances User Experience across different devices

● To disable auto backup you should define in the application tag android:allowBackup="false"

● Through a xml configuration file you can define what to include and exclude. Use in the application tag android:fullBackupContent="@xml/mybackupscheme"

<full-backup-content>

<include domain=["file" | "database" | "sharedpref" | "external" |

"root"]

path="string" />

<exclude domain=["file" | "database" | "sharedpref" | "external" |

"root"]

path="string" />

</full-backup-content>

● In earlier Android versions you are still able to provide and use your BackupAgent
