Android Example of using Thread Class for Multithreading App

Here is a simple example of using the Thread Class for a Multithreading application . Shows how to use the Progress Dialog, Handler, and running on the UI Thread. Also how to handle the Looper.prepare() error (“java.lang.RuntimeException: Can’t create handler inside thread that has not called Looper.prepare()”).

Check out my attempted to explain an example of using the Android Thread class.

Creating a Camera Application in Android Example

Here is a full example of building a camera app in Android that was taken from the Google tutorial.This is the complete tested camera code all in one place with no errors. There was a few errors i got from copying and pasting the code from the Google tutorial but they are fixed in this example. I also added code to display the last image taken so the user can open the picture in a image viewer. I removed excess code without testing so comment if you are having issues so I can make corrections.

This is image for an application I created so the layout below will not include the text or ads.

A rendering of the two center buttons

Here is how to center 2 buttons inside a layout. These do not have to be buttons but can be any type of view.

Since each layout is set to ‘match_parent’ then it will scale to any screen size.

Abandon President Roosevelt Railroad and Engine

We took a trip to look for an abandon Engine in a field today but was surprise to also find the abandon Roosevelt railroad M line. This was a 7 mile rail line that President Roosevelt took as he went down to Warm Springs Georgia. The President rode the line around 50 times and his funeral train rode this line. There use to be a Museum at this location but also has become abandon. The engine in the photo was built in 1892. There is another image of a cart that they was planning on taking tours on. I found some 2009 Youtube videos of maintenance workers using it and traveling down the rail line.
