Android OS have Flash support
iPhone OS
It is impossible on iPhone.

iPhone syncing only with iTunes
Apple charges for the App developers $100
While the iPhone only has html5 support

9. Android Components There are 4 basic components of an Android
Application :
Activity
Service
Broadcast Receiver
Content Provider

10. activity An Activity represents a single screen with UI.
Activity class takes care of creating a window in
which UI can be placed with the method
setContentView(View)
While activities are often presented as full screen
windows, they can also be used as floating
windows or embedded inside another activity.
The onCreate(Bundle) is where you initialize your
activity.
All activity classes must have a corresponding
<activity> declaration in their package’s
AndroidManifest.xml

11. Intent receiver They listen to broadcast intents.
They must be registered (either in code or within the
AndroidManifest.xml).
Intent Filters must be used to specify which Intents it
is listening for.
A broadcast receiver can be registered using
multiple intent filters.
The onReceive() method be overridden to perform
any operations.

12. service A Service is a component that runs in the
background to perform long-running operations or
to perform wok for remote processes.
Each service class must have a corresponding
<service> declaration in its package’s
AndroidManifest.xml
A service does not provide user interface.
Another component, such as an activity, can start
the service and let it run or bind to it in order to
interact with it.

13. Content provider Content providers are one of the primary building
blocks of Android applications, providing content
to applications.
They encapsulate data & provide it to applications
through a single interface called ContentResolver.
A content provider is only required if there us a
need to share data between multiple applications.
For example, the contacts data is used by multiple
applications & must be stored in a content
provider.

14. Android manifest.xml
<?xml version="1.0" encoding="utf-8"?>  <manifest xmlns:android="         package="com.example.android.wearable.timer" >       <uses-sdk android:minSdkVersion="20"               android:targetSdkVersion="22" />       <uses-feature android:name="android.hardware.type.watch" />       <application                                                 android:allowBackup="true">           <!-- Timer components -->         <activity android:name=".SetTimerActivity">             <intent-filter>                 <action android:name="com.android.example.clockwork.timer.TIMER"/>                 <category android:name="android.intent.category.DEFAULT"/>             </intent-filter>             <!-- Set a timer voice command -->             <intent-filter>                 <action android:name="android.intent.action.SET_TIMER"/>                 <category android:name="android.intent.category.DEFAULT"/>             </intent-filter>         </activity>           <service android:name=".TimerNotificationService" />       </application> </manifest>
