Overview
Compatibility

The NDK supports the 

mips

 ABI, which allows native code to run on Android-based devices that have CPUs supporting the MIPS32 instruction set.

Overview概述

To generate MIPS machine code, include 

mips

 in your 

Application.mk

 file's 

APP_ABI

 definition.
For example:

APP_ABI := mips

For more information about defining the 

APP_ABI

 variable, see 

Application.mk

.
The build system places generated libraries into 

$PROJECT/libs/mips/

, where 

$PROJECT

 represents your project's root directory, and embeds them in your APK under the 

/lib/mips/

 directory.
The Android package manager extracts提取 these libraries when installing your APK on a compatible MIPS-based device, placing them under your app's private data
directory.
In the Google Play store, the server filters applications so that a consumer sees only the native libraries that run on the CPU powering his or her device.

Compatibility

MIPS support requires, at minimum, Android 2.3 (Android API level 9). If your project files target an older API level, but include MIPS as a targeted platform, the NDK build script automatically selects the right
set of native platform headers/libraries for you.
