http://source.android.com/source/initializing.html
Put the following in your .bashrc (or equivalent):
export USE_CCACHE=1
export CCACHE_DIR=/run/media/root/158a840e-63fa-4544-b0b8-dc0d40c79241/ccache
-----------------------
In the root of the source tree, do the following:
[root@localhost android-6.0.1_r46]# pwd
/run/media/root/158a840e-63fa-4544-b0b8-dc0d40c79241/android/android-6.0.1_r46
[root@localhost android-6.0.1_r46]# ls

prebuilts/misc/linux-x86/ccache/ccache -M 50G
The suggested cache size is 50-100G.
On Linux, you can watch ccache being used by doing the following:
watch -n1 -d prebuilts/misc/linux-x86/ccache/ccache -s

++++++++++++++++++++++++++++++++++++++++
The suggested cache size is 50-100GB. You will need to run the following command once you have downloaded the source code:
prebuilts/misc/linux-x86/ccache/ccache -M 50G
. build/envsetup.sh
lunch aosp_arm-userdebug
make -j4
