The CDD enumerates the software and hardware requirements of a compatible Android device.3 Pass the Compatibility Test Suite (CTS). You can use the CTS (included in the Android source code) as an ongoing aid to compatibility during the development process.

7.Advantages & Disadvantages

7.1Advantages:1 Open-

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

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

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

and run Android applications including different tools

7.2 Disadvantage:1 Security-

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

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

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

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

8.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

Participating in many of the successful open source projects

Aims to be as easy to build for as the web

Google Android is stepping into the next level of Mobile Internet
