8.Advantages & Disadvantages

8.1Advantages:8.1.1 Open-

Android allows you to access core mobile device functionality through standard API calls

8.1.2 All applications are equal-Android doesn’t difference between the

phone’s basic & third party application even the dialer or home screen can be replaced

8.1.3 Fast & easy development-The SDK contains what you need to build

and run Android applications including different tools

8.2 Disadvantage:8.2.1 Security-

Making source code available to everyone indirectly invites the attention of black hat hackers

8.2.2 Open Source-A disadvantage of open-source development is

that anyone can scrutinize the source code to find vulnerabilities & write exploits

8.2.3 Login-Platform doesn’t run on an encrypted file system & has vulnerable log-in

9.ConclusionAndroid is truly open, free development platform based on Linux and open source.Handset makers can use & customize the platform without paying a royalty. Android is open to all: industry,

developers and users
