Fragment method and socket.io
- by Tolgay Toklar
I have a method,this method updates an array list in fragment.I can call this method in main activity like this
public void getFromUser(String message) {
addMessageToFragment("ok");
}
public void addMessageToFragment(String message) {
Log.w("Step 1",message);
frgObj.addMessageToList("asd");
}
getFromUser is calling from fragment(when user presses the button) this is working as well.But I am using socket.io in my app,when I try to call this method from socket.io,app is not working.
public void on(String event, IOAcknowledge ack, Object... args) {
try{
addMessageToFragment("ok");
} catch (JSONException e) {}
}
When this callback function calls,app is giving this errors:
