Getting Started with Android

The MIPS emulator can be built from the Android Open Source Project releases by Google. For every Android release, QA is performed and bugs found in the process are fixed. These bug-fixes along with any MIPS optimizations go on top of the Android release branch and get released by MIPS. Eventually all the bug-fixes and optimizations get submitted to the AOSP. It is hence recommended to download the latest MIPS releases from the instructions below to get the most stable version of Android sources for MIPS.

Setting Up Your Development System

The web pages below from the official Android website should get you started with setting up a system to compile Android sources.

Initializing a Build Environment Downloading and Building

Downloading the Android sources from MIPS releases

The MIPS releases are hosted at github. The first time you run the repo sync it will download several gigabytes of source code to your machine so be patient. Once the download is completed future updates may take only a few minutes since only the code changes are downloaded.

Compiling Sources for MIPS from the Jelly Bean release

. build/envsetup.sh
lunch full_mips-eng
make –jX
where X is dependent on the number of cores the host machine has. On a four core machine, X can be 8.

Bringing up emulator
