      1 Scripting Layer For Native
      2 =============================
      3 
      4 ### Introduction
      5 Scripting Layer for Native, SL4N, is an automation toolset for calling Android native Binder
      6 APIs and accessing the HAL layer in an platform-independent manner. This tool enables remote
      7 automation of these layers via ADB.
      8 
      9 ### Build Instructions
     10 Building SL4N requires a system build.
     11 
     12 For the initial build of Android:
     13 
     14     cd <ANDROID_SOURCE_ROOT>
     15     source build/envsetup.sh
     16     lunch aosp_<TARGET>
     17     make [-j15]
     18 
     19 *where `<ANDROID_SOURCE_ROOT>` is the root directory of the android tree and `<TARGET>` is the lunch
     20 target name*
     21 
     22 Then Build SL4N:
     23 
     24     cd <ANDROID_SOURCE_ROOT>/packages/apps/Test/connectivity/sl4n
     25     mm [-j15]
     26 
     27 ### Install Instructions
     28 Run the following command:
     29 
     30     adb push <ANDROID_SOURCE_ROOT>/out/target/product/<TARGET>/system/bin/sl4n /system/bin
     31 
     32 Library dependencies required:
     33 
     34     adb push <ANDROID_SOURCE_ROOT>/out/target/product/<TARGET>/system/lib/libbinder.so /system/lib
     35     adb push <ANDROID_SOURCE_ROOT>/out/target/product/<TARGET>/system/lib/libchrome.so /system/lib
     36     adb push <ANDROID_SOURCE_ROOT>/out/target/product/<TARGET>/system/lib/libevent.so /system/lib
     37 
     38 Optional library dependency for running tests that exercise the Bluetoothtbd service:
     39 
     40     cd <ANDROID_SOURCE_ROOT>/system/bt/service
     41     mm [-j15]
     42     adb push <ANDROID_SOURCE_ROOT>/out/target/product/<TARGET>/system/bin/bluetoothtbd /system/bin
     43 
     44 ### Run Instructions
     45 a) SL4N is launched from ADB shell; or  
     46 b) To enable RPC access from the command prompt:
     47 
     48     adb forward tcp:<HOST_PORT_NUM> tcp:<DEVICE_PORT_NUM>
     49     adb shell -c "/system/bin/sl4n" &
     50 *where `<HOST_PORT_NUM>` and `<DEVICE_PORT_NUM>` are the tcp ports on the host computer and device.*
