| Android is all around inhospitable to music apps. The link in a sibling post here is just part of the problem - as far as I can tell, Android has no libraries that are useful for serious A/V work. On iOS, in the span of a short morning I can hook up a button or slider to send out MIDI messages over WiFi to my MBP and route it to any device I want; I have no idea how to get the equivalent setup on Android. What if I want to decode an mp3 and process the resulting audio? I can tell you two ways on iOS, I know of a vague direction that might work for Android. You have to dive down into the NDK to do it, too. What about compositing video? Well... Seriously, here is AVFoundation on iOS. This is a high-ish level Obj-C interface for mucking about with AVAssets, which can be audio or video: http://developer.apple.com/library/mac/#documentation/AVFoun... This is just a single library dedicated to a single level of abstraction. Video composition, audio mixing, playback control and monitoring... there's a lot going on just here. You've also got CoreMIDI, AudioQueues, AudioUnits/AUGraphs, MusicPlayer... they're not easy to pick up, but they're there and they can do serious work. Here is what you can do in Java on Android: http://developer.android.com/reference/android/media/package... You can play encoded media, you can capture a raw input stream or direct it to an encoded file, you can play raw PCM... that's it. Really. To my knowledge, I'm not exaggerating when I say that - I'd be in debt to whoever proved me wrong, so please do! For graphics on Android, there's usually something analogous you can get by with. For audio, though, it's just... not there at all. |
