Why is Android SDK on my phone?

Native Android applications (or more precisely, native sections of Android applications) are written in C and compiled directly to the machine code of a specific platform . This means that the NDK section of the application is less portable, unless you compile it specifically for every different instruction set.

A native mobile app is a smartphone application that is coded in a specific programming language , such as Objective C for iOS or Java for Android operating systems. Native mobile apps provide fast performance and a high degree of reliability.

The Android SDK is a software development kit that includes a comprehensive set of development tools . These include a debugger, libraries, a handset emulator based on QEMU, documentation, sample code, and tutorials.
