Difference between android-support-v7-appcompat and android-support-v4 -


i wanted know difference between android-support-v4.jar , android-support-v7-appcompat.jar. if want add appcompat action bar in application need add both android-support-v7-appcompat.jar , android-support-v4.jar or android-support-v7-appcompat.jar.

also, android-support-v13.jar has appcompat?

below difference support library packages:

v4 support library

this library designed used android 1.6 (api level 4) android 2.3 (api level 9) , higher. includes largest set of apis compared other libraries, including support application components, user interface features, accessibility, data handling, network connectivity, , programming utilities.

v7 libraries

there several libraries designed used android 2.1 (api level 7) android 2.3 (api level 9) , higher. these libraries provide specific feature sets , can included in application independently each other.

v7 appcompat library

this library adds support action bar user interface design pattern.

note: library depends on v4 support library. if using ant or eclipse, make sure include v4 support library part of library's classpath.

so yes need both jars if want use v7.

update android-support-v13.jar

v13 support library

this library designed used android 3.2 (api level 13) , higher. adds support fragment user interface pattern (fragmentcompat) class , additional fragment support classes

when see package details has class fragmentcompat given in definition. has not classes of appcompat library.
