Has anyone successfully integrated Facebook SDK 3.0 with android? I am getting the error “Cannot call Login Activity with null package”
Thanks.
If I follow the Facebook tutorial as it is to integrate it into android, it works. Which means that if I create a pure java project without cocos2dx, the facebook integration works as expected. If I do the same thing in a cococ2dx project, it crashes. Anyone figured this out?
Hi, did you complete your fb android integration? 
i want favour
Do you have any code snippets of how you’re trying to call the Facebook API with cocos2dx?
Hi,
This might help.
Thank you.
`gamier No have not yet been able to do it.
`Daniel
This is the java class that is initializing facebook as soon as it is created
`public class Test0001 extends Cocos2dxActivity{
static private Test0001 instance;
static private String userName;
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
Test0001.instance = this;
Intent intent = new Intent(this, com.facebook.LoginActivity.class);
startActivityForResult(intent, 1);
Session.openActiveSession(this, true, new Session.StatusCallback() {
// callback when session changes state
`Override
public void call(Session session, SessionState state, Exception exception) {
if (session.isOpened()) {
// make request to the /me API
Request.executeMeRequestAsync(session, new Request.GraphUserCallback() {
// callback after Graph API response with user object
`Override
public void onCompleted(GraphUser user, Response response) {
if (user != null) {
// TextView welcome = (TextView) findViewById(R.id.welcome);
// welcome.setText("Hello " + user.getName() + “!”);
Log.i(“tag”,"username is "+user.getName());
}
}
});
}
}
});
}
static {
System.loadLibrary("game");
}
`Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
Session.getActiveSession().onActivityResult(this, requestCode, resultCode, data);
}

@Sameer I need to initialize facebook. I have figured out hot to make JNI calls.
Hi,
I have implement this in Cocos2dxHelper by making new method.it is working fine.
No need to init facebook object.well i am also working on facebook3 to optimize it.
if need then i can post my code here.
Thank you.
`nidhi i had implemented Fb integration with android and it is working i also implemented it in cocos2dx i have a class that is using JNI to make calls…Butt am getting errors 
`sameer please post your code.
`Sameer If you could post your code, that would really help I am using Facebook SDK 3.0
`Gamier can u post source code where you are getting errors? And what are the errors?
Hi All,
In $coco2dxHome/cocos2dx/platform/android/application.cpp
add new method
void CCApplication::postMsgOnFacebook(char *msg){
JniMethodInfo minfo;
if(JniHelper::getStaticMethodInfo(minfo,

“postMsgOnFacebook”,

minfo.env~~>CallStaticVoidMethod(minfo.classID, minfo.methodID, StringArg1);
minfo.env~~>DeleteLocalRef;

If need then i can upload old facebook sdk here.
Thank you.
Hi sameer,
I dont know about facebook3…I m doing integration with facebook android sdk if you have codes then please post it.
Hi,
I can’t send the old facebook sdk,as i am working for company so please try to find on internet.
Thank you.
So it turns out that the integration works as long as I call a void java function from c++. The minute I try to call a function that returns a string, it crashes.
same here …

Hi,
Can please post all code here including Cocos2dxHelper.java,CCApplication.cpp
Thank you.
Hi Sameer,
Sorry for the late reply. I figured it out. I was trying to return a string whose value was NULL as the facebook call had not been completed. Any idea how we can call c*+ form java? I tried what they say here http://www.cocos2d-x.org/projects/cocos2d-x/wiki/How_to_use_jni but I am getting errors saying that the function is being redefined. What I need to do is pass back the username from java back to c*+ once the facebook callback is complete. I know that I can call a function after a certain amount of time from c++ to java but this will not be correct as the network processing might take time and I will still get a null parameter.
Thanks,
Nidhi
`Gamier what version of the sdk are u using? Are u using JniHelper? It really solves things down. From the looks, u are trying to pass a string a string as an argument to the function, correct? This is my JNI call to a static function that takes zero parameters and returns a string
`JniMethodInfo t;
// get method ‘getResolution’ which returns int array ‘()[I’ from java package ‘com.mygame’ & ‘MyGame’ class
if (JniHelper::getStaticMethodInfo(t,
“com/WBS/Test0001/Test0001”,
“LoginFB”,
“()Ljava/lang/String;”))
{
jstring stg = (jstring)t.env~~>CallStaticObjectMethod;
const char *name = t.env~~>GetStringUTFChars(stg,NULL);
CCLog(“name is %s”,name);
}@
From what i understand of JNI, u need to pass the string as a parameter to this function call “t.env->CallStaticObjectMethod(t.classID, t.methodID);” I will look it up and get back on that.
@gamier Have a look at this http://blog.csdn.net/kafei_kings/article/details/8106744
Its in chinese but if u look at the code, u will understand how to pass parameters.
