Android Build: Tips and Tricks

Android Build: Tips and Tricks

All below build steps are trivial, but i took like a week to get a grip of..  just documenting to be handy.

$MYDROID is root of your android source directory.

Quick Incremental Build

Setup the environment for your build setup, go to moudle's directory with Android.mk and build.
`source $MYDROID/build/envsetup.sh`
`cd ./hardware/ti/omap3/liboverlay`

`mm`

Note: `mm -B` will clean build all the libraries under a subdirectory.

Package build

Building .apk in android SDK. No need of eclipse or PDK.

`source $MYDROID/build/envsetup.sh`
`mmm <path-to-package> `

(say #mmm $MYDROID/packages/gallery)

Selective Clean

`make clean-<modulename>`

(eg. #make clean-libomxcommon )

Complete clean 

`make clean`  works but, "rm -rf ./out" is faster

Display full commands

`make showcommands`

Number of parallel threads

This is same as GNU make, and chose it based on number of cpu cores available.
`make -j<number-of-parallel-jobs>`
