Hi there

I want to know what is support library in android?

I am try to use CalendarView in android app My MinimumSDK version is 8 and it shows a Warning that minimum support level is 11.

What it actually mean that I should change my minimumSDK to 11 or is there any way that CalendarView can run on my current mimimum API level which is 9?


I also want to know what is difference between android-support-api-compact7 and app-compact7?

Thanks

The support library is a collection of additional classes for the Android API developed by Google; they're all in the "android.support" package hierarchy. You can obtain it through the SDK tool "android", where you also get all your other SDK and tool updates. Initially it was a backport of some newer Android classes to older API levels, but these days it contains all kinds of goodies.

There is no backport of the android.widget.CalendarView class to API levels before 11, though, so you can't use it on Android 2.x. If you search on the net, I'm sure there are 3rd party calendar widgets that do support it, though.

Thanks Ulf

What is difference between "android-support-v7-appcompact" and "appcompact-v7"?

It's probably the same. "appcompat" is one of the 3 parts of the v7 support library. There are 3 support libraries: v4, v7 and v13, with the numbers referring to the minimum API level they support. If you download the support library and look at its directory structure and contents, all this should make sense.

One More Question


I am making a Calendar Application which will display some Events on some Specific Dates.I have 2 approach.

1)Using CalendarProvider API for Insert,query,delete on Calendar Events
2)Using GridView Describe in this Thread http://stackoverflow.com/questions/13002009/how-to-add-icon-or-change-calendarviews-day-icon

My Data of Specific Date will come as a Form of JSON which I will display or Parse

Which one is Best in above two

Thanks

I don't see how the two are alternatives to one another - to the contrary, they're orthogonal. #1 is about storing data in the calendar DB (not about display), whereas #2 is about displaying data (but not storing it).

Where the data comes from, and in which format, is irrelevant.
