Jade Android standalone execution

Question

I want to use Jade as standalone in Android environment.

Of course I'm using JadeLeapAndroid 4.3.3

I found these posts which was very helpful,

http://permalink.gmane.org/gmane.comp.java.jade.devel/12271
http://jade.tilab.com/pipermail/jade-develop/2013q1/018940.html

but I have a problem now.

I can bind service via this code.

[code starts here]

public void bind() {
    sc = new ServiceConnection() {
        @Override
        public void onServiceConnected(ComponentName name, IBinder service) {
            Log.d("SERVICE", "Bind Success");
            binder = (RuntimeServiceBinder) service;
            container();
        }

        @Override
        public void onServiceDisconnected(ComponentName name) {
            Log.d("SERVICE", "Bind Fail");
            binder = null;
        }
    };

    Log.d("SERVICE", "Bind Trial");
    bindService(new Intent(getApplicationContext(), RuntimeService.class),
        sc, Context.BIND_AUTO_CREATE);
}

[code ends here]

But when I continues with AgentContainer with this code,

[code starts here]

public void container() {
    Profile profile = new ProfileImpl();

    binder.createAgentContainer(profile, new RuntimeCallback<AgentContainerHandler>() {
        @Override
        public void onSuccess(AgentContainerHandler agentContainerHandler) {
            try {
                Log.d("CONTAINER", "Startup Success");
                ContainerController cc = agentContainerHandler.getAgentContainer();
                //AgentController ac = cc.getAgent("Arin");
                AgentController ac = cc.createNewAgent("TestAgent", TestAgent.class.getName(),
                        new Object[] { new Object() });
                ac.start();
                //agent(agentContainerHandler);
            } catch (ControllerException e) {
                e.printStackTrace();
            }
        }

        @Override
        public void onFailure(Throwable throwable) {
            Log.d("CONTAINER", "Startup Fail");
        }
    });
}

[code ends here]

it shows error on FileNotFound (EROFS) exception.

(It occurs even I deleted all codes in onSuccess method)

Actually, this is Permission error from Android that prevents app from write file to /system or /data even I added permission of WRITE_EXTERNAL_STORAGE, READ_EXTERNAL_STORAGE.

What should I do?

I'm guessing it might be a problem of profile, am I right?

Thanks in advance

Answer 1

For someone needs help on this, you can change path with Profile

for example,

Profile p = new ProfileImpl();
p.setParameter(Profile.FILE_DIR, Environment.getExternalStorageDirectory().getAbsolutePath()+"/jade/");

Of course, make sure that add permission in manifest

android.permission.WRITE_EXTERNAL_STORAGE and READ permission too.

But it doesn't matter whether you do it or not for executing JADE container
