Why android first
1 like547 views
Android has several advantages over other mobile platforms for developers: 1. It has a lower cost of development since the tools are free and run on all devices, registration is cheaper, and the OS is free and open-source. 2. Java is a widely used and familiar language for most developers. 3. Android was designed to run on multiple device types and configurations, making it easier to support different screen sizes and resolutions. 4. Features like services, broadcasts, and a consistent lifecycle model allow for true multitasking and background processing without worrying about apps being killed.

- 7. Advantage 1: Cost • Tools are free and run on all devices • Market registration is the cheapest at 25$ one time fee. • OS is free : Advantage better understanding • More Free Apps : Better for the user , more user = larger market
- 8. Advantage 2: Familiar Language • Java is a more largely adopted language. • Most developers already know Java. • Developer has the option of writing Android apps in Scala.
- 9. Advantage 3 : Multiple device support • Was designed to run on multiple devices. • Configuration qualifiers for resources • UI Design based on rules rather than absolute positions.
- 10. Advantage 3: True multi tasking • Allows the apps to run in the background. • Services are purely background apps with no UI • BroadcastReceiver component lets apps wake up for a short time to run some task and then return to background state • Lifecycle is maintained and the developer need not worry about killing an app.
- 11. Advantage 4 : Back Button • More intuitive flow, just like your browser. • Allows saving screen space :-P • Makes it easier for an app to user another apps component and return to where the user was.
