Removing the now-unusable HtmlInterpreter

-Because Webview security was increased in API level 21, views
 can no longer be launched external to apps. Thus this capability
 no longer works. Leaving it in will cause SL4A to throw security
 exceptions.

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 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:

    perl Docs/generate_api_reference_md.pl

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.
