Scripting Layer For Android
|
|
=============================
|
|
|
|
### Introduction
|
|
Originally authored by Damon Kohler, Scripting Layer for Android, SL4A, is an automation toolset
|
|
for calling Android APIs in a platform-independent manner. It supports both remote automation via
|
|
ADB as well as execution of scripts from on-device via a series of lightweight translation layers.
|
|
|
|
### Build Instructions
|
|
Due to its inclusion in AOSP as a privileged app, building SL4A requires a system build.
|
|
|
|
For the initial build of Android:
|
|
|
|
cd <ANDROID_SOURCE_ROOT>
|
|
source build/envsetup.sh
|
|
lunch aosp_<TARGET>
|
|
make [-j15]
|
|
|
|
*where `<ANDROID_SOURCE_ROOT>` is the root directory of the android tree and `<TARGET>` is the lunch
|
|
target name*
|
|
|
|
Then Build SL4A:
|
|
|
|
cd <ANDROID_SOURCE_ROOT>/external/sl4a
|
|
mm [-j15]
|
|
|
|
### Adding SL4A Builds to Android Builds by Default
|
|
1) If you are not using a custom buildspec, create one as follows:
|
|
|
|
cp <ANDROID_SOURCE_ROOT>/build/buildspec.mk.default <ANDROID_SOURCE_ROOT>/buildspec.mk
|
|
|
|
2) Modify the buildspec to build SL4A as a custom module by editing
|
|
the line '#CUSTOM_MODULES:=' to 'CUSTOM_MODULES:=sl4a':
|
|
|
|
sed -i 's/#CUSTOM_MODULES:=/CUSTOM_MODULES:=sl4a/' <ANDROID_SOURCE_ROOT>/buildspec.mk
|
|
|
|
### Install Instructions
|
|
Run the following command:
|
|
|
|
adb install -r <ANDROID_SOURCE_ROOT>/out/target/product/<TARGET>/data/app/sl4a/sl4a.apk
|
|
|
|
### Run Instructions
|
|
a) SL4A may be launched from Android as a normal App; or
|
|
b) To enable RPC access from the command prompt:
|
|
|
|
adb forward tcp:<HOST_PORT_NUM> tcp:<DEVICE_PORT_NUM>
|
|
adb shell "am start -a com.googlecode.android_scripting.action.LAUNCH_SERVER \
|
|
--ei com.googlecode.android_scripting.extra.USE_SERVICE_PORT <DEVICE_PORT_NUM> \
|
|
com.googlecode.android_scripting/.activity.ScriptingLayerServiceLauncher"
|
|
*where `<HOST_PORT_NUM>` and `<DEVICE_PORT_NUM>` are the tcp ports on the host computer and device.*
|
|
|
|
### Generate the API Documentation
|
|
From SL4A source directory run this command:
|
|
|
|
python Docs/generate_api_reference_md.py
|
|
|
|
In the Docs directory there should now be an ApiReference.md file that
|
|
contains which RPC functions are available in SL4A as well as documentation
|
|
for the RPC functions.
