为什么Android Studio（NDK）使用C++

Question

I have a question that why is C++ used in Android App Development, What Requirements aren't Full filled by Java or Kotlin so C++ Came to Picture.

Answer 1

Android by itself is kind of linux system, where app is run by davlik virtual machine (and byte code for it is compiled form java / kotlin). Sometimes there is a need to be closer to operation system and develop in native code - say in C/C++. NAtive parts of software have access to other APIs not available from davlik VM
