My app requires that devices are running at least Android 2.0 OS. Would it make more sense for me to compile my project with the 2.0 SDK or does it make more sense to always compile my project using the latest SDK, even if it's well beyond 2.0...? The problem with compiling against 2.1 for example would be that I don't know if an Androi...

If the keyphrase doesn't exist, then my app does nothing. I have this much working. I was wondering if there was a way to prevent the default s...

What is the difference between their approach...
I have a large bitmap (say 3888x2592) in a file. Now, I want to resize that bitmap to 800x533 and save it to another file. I normally would scale the bitmap by calling Bitmap.createBitmap method but it needs a source bitmap as the first argument, which I can't provide because loading the original image into a Bitmap object would of cours...

So here's the deal: I've got a JNI wrapped version of MPG123 for Android, and I can pull PCM data from an MP3 file on the SDCard. I'd like to pull a chunk this data, do an analysis on it using another class I wrote, then push it into a queue. Ideally, I'd...
