What I want to do, is be able to access the object neoApi inside the Neoseeker class, from its inner class RunningTimer. Now, in my code, you can see what I would think to work, but when I run my application, nothing pops up. Nothing inside my TextView, no Toast, nothing at all. How can I remedy this?
package com.neoseeker.android.app;

import org.json.JSONObject;
import android.app.Activity;

View 1 Replies View RelatedI'm attempting to make a simple homebrew game engine/framework in android. I have the "engine" as a library project that handles all of the graphics rendering, game activity, and whatnot. Essentially, the library project has a class GameMain which has a background image, an array of drawables, and a few functions (the most important is a run() function). The projects that use this library extend this class with their own unique run() function. The idea is that games that use the engine start with their own activity, launch the GameActivity from the library, and pass their unique GameMain child object into the library, which should run the unique run() method thanks to polymorphism.
Getting this to work, however, has been a struggle. I originally attempted to make the GameMain Serializable, which didn't appear to work. I'm now attempting to make it a Parcelable, but it does not appear to run the child objects run() function when called from the library. I'm wondering, are Parcelable objects actually capable of sending Object methods across activities? Am I going about this the wrong way, or am I just having some other weird bug I have not uncovered?
I am developing an application which incorporates socket programming. I need to refer to the socket object created in the starting application when connected to a server in any other activity in that application .
Can I define a class in an acitivity and define a socket as a static field in that class and refer to that socket object from any other activity in that application?

View 3 Replies View RelatedI have a class A which is responsible for fetching data from web services in android and i have a class B which is responsible for creating and rendering List View in android
Now how can i populate data on List View once the data is fetched successfully.
well i have following options but which one is better .. (if someone has anyother then i don't mind)
1) Create an intent of Class B and
pass the data that need to be
populated
2) Creating a static method int Class
B which will accept the data as an
argument and call setListAdapter
in class B i have used Holder Patter to create ListActivity. ( for reference List14.java in samples of Android )

View 4 Replies View RelatedI create a WebView object in the OnCreate function. Now I need to be able to pass this same object to other functions in the code, such as the onOptionsItemSelected function. I currently have it where I just create a new WebView object in each function where I need it, but this slows down the code since it has to recreate it and such.

View 2 Replies View RelatedI'm building an android application, which has a list view, and in the list view, a click listener, containing an onItemClick method. So I have something like this:
public class myList extends ListActivity {
@Override
public void onCreate(Bundle savedInstanceState) {
getListView().setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
/* Do something*/
}
}
}
Normally, this works fine. However, many times I find myself needing too preform an application using the outer class as a context. thusfar, I've used: parent.getContext(); to do this, but I would like to know, is that a bad idea? I can't really call: because it's not really a subclass, just an embedded one. So is there any better way, or is that considered cosure? Also, if it is the right way, what should I do if the embedded method doesn't have a parameter to get the outside class?

View 1 Replies View RelatedWe have a website that makes use of OAM for single sign on (form-based authentication). When we submit credentials to WebGate / Access Server the authorization succeeds, however after the authentication is performed, the form action (as configured in the Authentication Scheme - with passthrough:no) returns a server error instead of redirecting to the originally requested URL.
If we use Mini Opera, we are able to get authenticated and forwarded properly.
This problem happens on numerous Android phones (versions ranging from 1.5-2.2), as well as the Emulator provided with the SDK.
This is proving to be a real problem as the default browser on Android phones is not able to get access to our sites(and this is the only browser that is having this problem).

I want to do some automated testcase with Instrumentation . Suggest that my AUT has 2 Activity. After clicking the button in ther first Activity, the second one will be shown with new content base on what we enter in the first Activity.) Instrumentation provides us the function called startActivitySync() and return the Activity object for processing.

View 4 Replies View RelatedI'm just getting into Android development, and I have a question about communicating between a receiver class and an activity class. I'm very new to JAVA and Android so I hope I don't sound too stupid. I'm developing an application where I intercept an SMS message and then based on various elements of that SMS I might delete it once it's been saved to the inbox. I have a receiver class that intercepts the txt message, and I am also able to delete messages from my inbox with code in the activity class using a button at the moment. The problem I have is communicating between the receiver class and the activity class where the code to delete a message resides. I tried putting that code directly into the receiver class but as I'm sure most of you already know the BroadcastReceiver class doesn't seem to support what I need to delete messages. I've been searching for an answer to this for a while, but haven't been able to find anything. Honestly I'm not sure I know enough about JAVA and Android to even recognize a solution if I saw it.
