Thread vs. Handler vs. Timer

I have seen all three used, and I would really like clarity on when I should use which. A tutorial or discussion about Thread vs. Handler vs. Timer would be greatly appreciated by me.

Also when to use Drawable vs Bitmap would be nice. Is a Bitmap faster to paint but harder to draw on directly? What separates these two?

Just things I would like clarified.

Hi I'm new to the Android platform but I've been able to learn quite a bit already. There is one thing bugging me at the moment and I cannot seem to find an obvious answer without searching deeply through all of Google's code and I was wondering if somebody could help. I do apologize if this is the wrong place for this post, please move it if it is, but I figured it could be a good Novice tutorial.

Essentially what I have right now is an app with an edit box and a button that takes the string and uses an Intent and the SearchManager to launch the browser and search Google for the string. This is easy enough I found the code on some other forum. However, what I would like to do is to perform a search and only receive the first url Google's search shows. I tried just parsing the page source but Google's page is not that simple. I think what needs to be done is to some how get the search manager to start the search without launching the browser and many instead have a Cursor collect all the URLs or even just the first. Maybe a Cursor isn't what I need I just THINK.. it is, limited knowledge and all. Essentially I would like to make a button that mirrors the "I'm Feeling Lucky" button on Google. Hopefully there is just some function that does that. Even better would be in I could get the function to just return the URL and then later allow me to launch the page in my own custom WebView, for learnings sake.

I would like to see a tutorial for how to set up this "SDL port for Android SDK/NDK 1.6" from step 1. The thread really didn't have a guide how to set it up and I haven't done it before. I have installed andLinux but don't understand what to download and how to set it up in the linux enviorment.

I am reading the readme that comes with the zipfile (branch a57f8e3). But googleing for "Ant" and hope to find what I look for isn't the easiest as I have no clue what Ant is nor how to set it up on the linux emulator (I ain't a native linux user)

So if any kind soul could help me (and possibly others) with setting it up so we can start learning would be nice!

Hi,

I am currently working on a login page.
After the user inputs the fields "email" and "password", they can choose either "sign up" or "log in".
I am currently using SQLite as my database.

Am wondering how can i link my login page to my database, in the sense that, when the user presses "log in", the app will access the database to check whether it is a valid "email" and "password", if correct, the homepage of the app will load, if incorrect, give an error message.

For the sign up button, it will just direct the user to another page, where they can register.

Anyone can help? Cause i am new to android and java programming.

THanks Alot!

Hello!

Please, i need tutorial how to create small Android (version 2+) application.

Android app for counting the time elapsed since a particular event. The user can add events.
For example the event "not smoke" from a certain date. The program should create an event with the text: "{event name} for {X} days {Y} hours {Z} minutes".

Hi!

I am new to Android and i am looking for an example/tutorial that solves the following (probably simple) problem:

In my app I have three imagebuttons. And when I press the button the image should change. And when I release the button the image should change back again. So as long as I press the button the appearance of the button should change. And the same thing should happend when I press a key, for example as long as I press the "1"-key the first of my three button should change appearance (the buttons image should change).

I have tried but failed. :-) So if anyone could help me i would be happy!

Hi, I have a Dell Streak and hate the fact you cannot set an orientation other than landscape so want to create an app like an orientation lock but where you choose which way round you want the screen locked. Where do I start??
