I am new in mobile development using Java and Kotlin, I had an application in Java which I needed to start in a new project.
When creating a new project in Android Studio, I checked Use androidx.* artifacts. After coping some dependencies from my old project, I had too many errors which I fixed by going to Refactor => Migrate to AndroidX
Now I want to now what is the difference between android and androidx packages.
Thanks in advance.
Android has been building up APIs that are backward compatable and has a lot of Android Support libraries that exist in developer APIs. To clean up this mess,Android introduced androidx libraries. AndroidX is a major improvement to the original Android Support Library. Like the Support Library, AndroidX ships separately from the Android OS and provides backwards-compatibility across Android releases. AndroidX fully replaces the Support Library by providing feature parity and new libraries
You can read about androidx here https://developer.android.com/jetpack/androidx

According to Compose to Kotlin Compatibility Map, ComposeCompiler must be compatible with Kotlin version.
Is there this compatibility relation between Compose and ComposeCompiler?
Which one should be newer?
I didn't find any document/reference to describe the relation.
It is highly recommended that you use the plugin version matching the library you are using as that combination has received the most testing.
Also, the compose plugin must match the Kotlin compiler version it was intended for so it is recommended that you use the Kotlin compiler version the plugin was built for.
However the minimum current runtime version supported runtime is 1.0.0. This means you can use newer versions of the compiler with older versions of the library.
Beginning with 1.0.0, the Compose Compiler Plugin will feature detect the runtime and generate the code compatible with the runtime it is given. This allows new plugins to be used with older versions of the library. If a feature or optimization requires support from the library and it is not there, it is disabled.
Also, for binary compatibility, the runtime is required to support code generated from older version of the plugin. This allows older versions of the plugin to work with newer libraries.
I was developed with AndroidX and it is a wonderful library, I run my demo app in my smartphone with Android 6, but I have a question, does AndroidX support Android 5.0 and lower?
It depends on the specific library, but on the whole the current set of androidx libraries support back to API Level 14 (Android 4.0).
With Android Studio 3.2 and higher, you can quickly migrate an existing project to use AndroidX by selecting Refactor > Migrate to AndroidX from the menu bar.

You read more stuff from there base on your tpoic!
I'm trying to add support libraries to my Android studio project.
studio suggests to use "27.1.1" version of appcompat library but is not available in jcenter or google repository.
my questions:
1.How can I find the latest available version of libraries?
2.why jcenter does not include support libraries(http://jcenter.bintray.com/com/android/support/appcompat-v7/27.1.1 this page is not found)
thank U every one
I have an android project developed on eclipse. I migrated it to Android Studio and updated the support libraries. It started showing some weired behavior related to UI. The project had some nested scrolling functionality which was not supported then. Now the support library itself provides support for nested scrolling so that is causing problem. Is there any way through which we can know what was version of support library.jar? Since in eclipse we used to add jar files in the libs folder.
Can you please suggest me how do I manually add xamarin support library v4 jar file to the Components or some other way so that I would be able to use DialogFragment and other features.
The same question has also been asked in this but no one has proposed the solution.
I am actually working on xamarin using visual studio 2012. I am unable to use DialogFragment and other features because of not proper configuration of xamarin support library v4 in visual studio. I have already installed xamarin support library v4 using sdk manager and it exists in C:\Users\username\AppData\Local\Android\android-sdk\extras\android\support\v4
but visual studio is not loading this library, although it loads automatically. This path contains android-support-v4.jar and src folder as well.
I have also tried installing using nuget but I get the following error
Could not install package 'Xamarin.Android.Support.v4 22.2.1.0'. You
are trying to install this package into a project that targets
'MonoAndroid,Version=v2.2', but the package does not contain any
assembly references or content files that are compatible with that
framework. For more information, contact the package author.
The Xamarin.Android.Support.v4 supports android 1.6 and higher.
I have looked on this answer but it did not help me.
Thank you.
