• Apps need to –– Check for permissions

– Request for permissions

– Handle lack of permissions gracefully

– Handle cases when permission revoked

• Best practices –– Ask only when required. Use intents if possible

– Don’t ask all permissions at once

– Explain the need for permission

• Alarms scheduled with the AlarmManager class are

disabled

JobScheduler are not permitted to run.

Other behavioral changes
