Android: Creating a button to load images from a remote server
Posted by Dimitri | Filed under Programming
This is a follow up to the post published two days ago that explained how to load images into a View’s Canvas from different sources. Differently from the last post, I will explain how to load images from a remote server after the View has been loaded and rendered on the screen. Also, this post features how to download an image after pressing a button.
So, let’s get to it. The first thing the reader might be thinking is that we just need to create a button and place the code that downloads the image inside it. It’s not as simple as that, due to these problems: (more…)

How to get Android local files URI
Posted by Dimitri | Filed under Programming
When programming applications for Android that requires the playback of audio or video files, sometimes, there’s the need to obtain the URI of those media files instead of using a String for the absolute path. But what is a URI? A URI (Uniform Resource Identifier) is an address to an local or internet resource. It’s more like a standardized path syntax that allows pointing to a specific resource that’s available over the internet, however we are going to use it to point it to a local resource.
A URI is specially useful, when using the VideoView class to load a video located on the res folder or in the SD card. Passing the video file to the VideoView as a String won’t even work on an emulated Android device. This way, we need to get the URI of the file.
