How to create a custom RPC facade

A custom RPC template has been added in the project package com.googlecode.android_scripting, this can be used as basis to create your own facade definition,

@RpcMinSdk(4)
public class ACustomFacade extends RpcReceiver {
private final CountDownLatch mOnInitLock;
public ACustomFacade(FacadeManager manager) {
super(manager);
mOnInitLock = new CountDownLatch(1);
mOnInitLock.countDown();
}
public void shutdown() {
}
@Rpc(description = "Print hello in logcat")
public void aHelloFonction(@RpcParameter(name = "message") String message) throws InterruptedException {
mOnInitLock.await();
Log.i(GlobalConstants.LOG_TAG, "ACustomFacade received: " + message);
}
}

- Adjust @RpcMinSdk(4) and add any needed permission used by the new code in AndroidManifest.xml.

Once your facade is created you need to register it in FacadeConfiguration.java

sFacadeClassList.add(ACustomFacade.class);

Then from Python code you can call the newly created RPC:

import android
droid = android.Android()
droid.aHelloFonction("hello rpc")

Note: you can extend the range of native code accessible through Python by using:

• a RPC facade and JNI + your own cross-compiled C code
• or directly without RPC use, by using ctypes and your own cross-compiled C code in a shared object (take care using the fullpath to your .so when loading it with ctypes: cdll.LoadLibrary("full_path_to_the_so"))
