Agenda
• What are Android Services
• Services vs. Threads
• Types of Services
• Android Service Wizard
• Demonstrations
• More Information

4. embt.co/sprint-android-servicesBlog Notes:
Why Android Services?
• Provide background functionality
• Can run even when app is closed
• Can start on boot or on other events
• Can be accessible by multiple apps
• Can contain multiple threads

5. embt.co/sprint-android-servicesBlog Notes:
Android Services vs. Threads
Android Services
• Cannot access the UI
• Runs in main thread of
host app process
• Can contain multiple
threads
• Used for long running
processes
Threads
• Cannot access the UI
• Not accessible to other
apps
• Terminated with app
• Used to improve
responsiveness

6. embt.co/sprint-android-servicesBlog Notes:
Android Service Type Variations
• IntentService
– Handle asynchronous requests (onHandleIntent(Intent) event)
– Otherwise are syncronous (onStartCommand(Intent) event)
– Both are Bindable (onBind event)
• Local vs. Remote
– Local only accessible by host (exported = false in manifest)
– Remote cross app access (exported = true in manifest)

7. embt.co/sprint-android-servicesBlog Notes:
Android Service Wizard
• Local Service
– Synchronous local access
• Intent Local Service
– Asynchronous local access
• Remote Service

9. embt.co/sprint-android-servicesBlog Notes:
Restrictions for Services
• Cannot Access UI
• Not use components from the FMX namespace
• Be aware of power consumption
– Using a lot of CPU
– Using network connection
• Respect users expectations and privacy

10. embt.co/sprint-android-servicesBlog Notes:
Service Workarounds
• Use RTL or low-level calls instead of FMX
components. If the service fails when started, use a
lower level call.
• Manually edit manifest to make remote services
published.
• Manually edit Java Templates for Intent and
Remote Services (See http://delphi.org/?p=2084)
