The error happen right after I posted message on Wall. I use activity.finish() right after I make that toast..
Toast.makeText(getActivity(), "Message posted succesfully", Toast.LENGTH_SHORT).show();
getActivity().finish();
The message run "posted successfully" which indicate I'm done sharing to Facebook..
The application then force close, I've been searching the solution for hours...
Can someone help me?
EDIT: Here's my callback response code, it's begin at line 145.
@Override
public void onCompleted(Response response)
{
FacebookRequestError error = response.getError();
if (error != null){
//Toast.makeText(getActivity() , error.getErrorMessage(), Toast.LENGTH_SHORT).show();
//getActivity().finish();
Cocos2dxHelper.setStringForKey("messageCB", error.getErrorMessage());
}
else{
// getActivity().runOnUiThread(new runnable(){
// public void run(){
// Log.d("UI thread", "I am the UI thread");
// }
// });
//Toast.makeText(getActivity(), "Message posted succesfully", Toast.LENGTH_SHORT).show();
//getActivity().finish();
Cocos2dxHelper.setStringForKey("messageCB", "Message posted succesfully");
}
//getApplicationContext().finish();
getActivity().finish();
Log.i("cocos2d-x debug info", Cocos2dxHelper.getStringForKey("messageCB", "unknown"));
AndroidNDKHelper.SendMessageWithParameters("Share", null);
}
I have to disable toast first, then notify pop-up to next activity
It seems that your Toast
is missing context. Try using getApplicationContext()
instead of getActivity()
.
