I updated the map tutorials to v1.5 as well.  There were enough tricky challenges to getting maps working on Android that I thought it best to pass the information along. Here are the source files for this tutorial as well as all my other tutorials.

Tutorial 1: Transparent Panel (Linear Layout) On MapView (Google Map)
Tutorial 2: “Hit” testing on a View (MapView)

The first challenge to using Google’s Maps in Android is simply informing Eclipse that you’ll need access to Google’s mapping API.  Instead of writing my own tutorial on this, I’ll simply point you to the same well-documented Android v1.5 MapActivity setup that I followed.

The second challenge as always is getting your Map API key to function properly. Google provides full details on installing your Google Map key.  I spent several hours trying to figure out why my API key wasn’t working though…my Google maps always displayed as empty white/gray tiles.  Eventually I tracked the problem down to the fact that Android had created multiple debug.keystore files on my computer.  I’m running Vista so my .keystores were located in both of these directories:

Incorrect: C:\Users\acopernicus\AppData\Local\Android\debug.keystore
Correct: C:\users\<username>\.android\debug.keystore

I wasted time by using the .keystore in my AppData folder as this was the original place where the .keystores were stored in Android v1.0.  However it now seems that Android now uses the .android directory instead.  If you have problems, figure out which directory Eclipse is pulling your .keystore from when signing your apps.
 

After spending the last year game programming on the iPhone, I’ve finally returned to Android.  My six prior tutorials were outdated (Android v1.0) so I took the time to update them to v1.5 (Cupcake).  The most popular of those tutorials was the Streaming MediaPlayer tutorial so that’s the primary focus of this post. 

At the time of initially writing the streaming tutorial, Android’s media streaming function didn’t work well so I wrote my own.  As of v1.5 however, Android’s MediaPlayer streams very well.  That said, it’s still useful to know how to retrieve a media file from a server and store it on the device.  This would be useful to immediate replay of the file at a later date or for caching files for later playback ‘off the grid’.

Download the source files to get started immediately and then view the rest of the tutorial after the jump.

First we want to thank everyone for their comments about our prior Android tutorials.  We’re very glad to have helped you guys.  Many of you have asked why we haven’t posted new tutorials, and the reason is that happily, we’ve spent the few months working hard on our submission into Round 2 of Android Challenge #1.  Yes…if you hadn’t heard already, we were one of the top 50 finalists.

As soon as Google releases the next SDK, we’ll write up more tutorials based on the lessons we’ve learned over the past months.

Until then, we’re getting out to exercise and enjoy some sunshine away from our desks.

Cheers,
