Prerequisites

You need to:

• have the Android NDK:

  • http://developer.android.com/tools/sdk/ndk/index.html
  • use the r5c version

• have the NSPR headers installed under /usr/include/nspr:

  • apt-get install libnspr4-dev, or
  • download from https://ftp.mozilla.org/pub/mozilla.org/nspr/releases/

• export these vars:

  • NDKPATH = path to the NDK folder
  • ADB_PATH = path to the adb binary

• have a running B2G emulator/device with the ports 20700 and 20701 forwarded:

  • adb forward tcp:20700 tcp:20700
  • adb forward tcp:20701 tcp:20701

• install busybox on the device:

  • ./setup-tools.sh

• have the toolchain:

  • source bootstrap.sh

Building, running

Just ./run.sh.

Including this in B2G

Just clone this repo inside $B2G_REPO/system/. Build and flash B2G as usual and then you will be able to run the agent using sutagent. It will be in the $PATH.

Start the agent on boot

Insert this after the exports in $B2G_REPO/gonk-misc/b2g.sh:

export NSPR_LOG_MODULES="NegatusLOG:5, timestamp"
sutagent &

NSPR Logging

Before running the agent (not necessary if you use run.sh):

export NSPR_LOG_MODULES="NegatusLOG:5, timestamp"

Data will be logged to $TESTROOT/Negatus.log.
