When you create a project, it comes with this library added by default:
android-support-v4.jar
Can I remove it? What happens if I remove the library? Can the app stop working in some phones?
In addition, the Support Libraries provide additional convenience classes and features not available in the standard Framework API for easier development and support across more devices. Originally a single binary library for apps, the Android Support Library has evolved into a suite of libraries for app development.
The Design Support library adds support for various material design components and patterns for app developers to build upon, such as navigation drawers, floating action buttons (FAB), snackbars, and tabs.
AndroidX is a major improvement to the original Android Support Library, which is no longer maintained. androidx packages fully replace the Support Library by providing feature parity and new libraries.
The Support Library is a static library that you can add to your Android application in order to use APIs that are either not available for older platform versions or utility APIs that aren't a part of the framework APIs. Compatible on devices running API 14 or later.
Can I remove it?

What happens if I remove that library?

, etc.
Can the app stop working in some phones?
