Android Applications

Android applications are usually developed in the Java language using the Android Software Development Kit.
Once developed, Android applications can be packaged easily and sold out either through a store such as Google Play, SlideME, Opera Mobile Store, Mobango, F-droid and the Amazon Appstore.

Limitation of android:- 

As many users who have switched from iOS to Android have noticed, the Android version of Runkeeper is somewhat limited when compared to its iOS twin. To clear up any confusion, we've compiled a short list of features unavailable or otherwise limited on Android.
  • Music must be played through a third party application such as Google Music, Pandora, Spotify, etc. instead of through the application.
  • There is no target pace option available.
  • Goal Coach is not currently available on Android.

Advantages of Android:

Cost Effective:
make-money
The first thing about Android is its cost.People  who used to be with base level mobiles would be fed up with the boring options.But with the low price now they can go for Android phones with good design and lot of applications which is not possible with the Apple,Blackberry and some.



Multitasking:
multitasking
Android  has a multitasking option so you can run many applications simultaneously.As this is not a new stuff nowadays but it comes under Advantage room.




Easy Access of Store:
androidstore
So the store is in the home screen which is easy to access the applications.You dont need to settle with the fixed applications as the store is filled,filling and will be filled with plenty of applications.


UserInterface Big Screen:
BigScreen
Android breaks the word ‘More Money Big Phone’.Yes you can afford a big screen android mobile with your savings.So there is no need to close your bank account.

 

conclusion:-

we hope that the next version of android to overcome actual limitation and future possibilities become a reality and may be developed to use in PC's also .
