java.lang.incompatibleclasschangeerror android.support.v4.content.contextcompat

Android Studio is upgrade to version 2.2 from 2.1.x.

But it happened critical problem for Authorization of Google SDK.

below statement is printed by studio.

" java.lang.incompatibleclasschangeerror android.support.v4.content.contextcompat "

It means that android support library v4 is not incompatible with another class. 

I don't know how to solve it. so I just googling and find out it's solution.

configuration.all {

resolutionStrategy {

force 'com.android.support:support-v4:23.3.0

}

}

Why it so happen ?? Because android gradle plugin updated to new version 2.2.0 from 2.1.3. 

New android gradle plugin is not supported dynamic dependency in version name. Like '+' version name means that is only newer version.

If plugin detect '+' version name , it will modify version name to newer. and it effect all of module in the project.

If you are using dynamic dependency like version name '+' , so you will be show the error log about Google like SDK or GMS.

also other open-source libraries don't know about this issue and don't fix it. 

If you are using a lot of libraries in android, You will be check them all about using android support library v4 version.
