the applications.
PROS & CONS

21. 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.

22. CONCLUSION & FUTURE SCOPE
 Android is open to all: industry, developers and
users
