4.SDK attibutes

In manifest file you need to specify the API version that application uses.Every time when google introduces new android version it will also release the API version that makes the application to be checked for compatibility.

<uses-sdk> needs MinSDK,MaxSDK,TargetSDK version number.If you are not specifying the MinSDK version then it defaults to 1 which means the application is compatibile to all android versions.
