ANDROID & IOT

Pros:

o The first thing about Android is its cost.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.

o Android has a multitasking option so you can run many

applications simultaneously.

the applications.

PROS & CONS

Cons :

o Source code available to everyone indirectly invites the

attention of black hat hackers.

o A disadvantage of open-source development is that anyone

can scrutinize the source code to find vulnerabilities & write

exploits also drain battery.

o Few Android Applications contain virus also present in

the AndroidMarket.Due the lack of Quality Standard many

applications contain viruses which makes your mobile hung.

CONCLUSION & FUTURE SCOPE

Android is open to all: industry, developers and

users

Android is now stepping up in next level of mobile

internet.

Participating in many of the successful open

source projects

There are chances of Android may become the
