Android: How to load an image from a file and set on an ImageView

If you’re working with an Android application, this source code seems to work to load an image from a file:

Bitmap bitmap = BitmapFactory.decodeFile(pathToPicture);

The Bitmap and BitmapFactory classes are located in the android.graphics package:

import android.graphics.Bitmap;
import android.graphics.BitmapFactory;

Assuming that your pathToPicture is correct, you can then add this bitmap image to an ImageView like this:

Sencha ExtJS - How to properly use the Store load method

I can tell you from my own recent experience that if you don’t use the Sencha ExtJS Store load method properly, nothing will happen. After torturing myself twice by mishandling the load method, I thought maybe it would help if I wrote a quick blog post about how to properly use the load method.

A collection of Scala XML tutorials

The following links are a collection of Scala XML tutorials I've written. Most of them come from the Scala Cookbook, while the others were written before I wrote the Cookbook.

Without any further ado, here are the links:

Android emulator not loading my app

I haven't used Android in a little while now, in particular with my new laptop, and the first time I tried running an Android app from inside Eclipse, the Android emulator wouldn't finish starting properly and run my app.

A Java Properties file method

In an earlier Java Properties file example I showed how to load a Java Properties file and then access the elements in the Properties object, but for today, if you just need a method to read a Java Properties file, I hope the following source code will be helpful to you:

How to load a Spring application context file from a standalone Java application

Here's the source code for a standalone Java application where I load a Spring application context file with the ClassPathXmlApplicationContext method. In other blogs I've shown how to load the application context for web applications, but I also wanted to show how to do this for a standalone program.

Here's a source code for my Java program that loads a Spring application context file from the typical main method:

How to load multiple Spring application context files for a web application

Here's an example web.xml configuration file where I show how to configure the Spring Framework to properly load for a Java web application. I'm intentionally trying to keep this Spring example simple, so my web.xml file has almost the bare minimum configuration.

I show how to load the Spring ContextLoaderListener class with the listener-class tag, and also show how to load multiple Spring application context files using the context-param, param-name, and param-value XML tags.
