Well, I was going to use Spotify on Android today. Wanted to take a couple more screenshots. Except that it’s self-destructed – the app utterly refuses to run, because there’s a newer version on the Marketplace (with no listed changes that apply to me). But I can’t download the version on the Marketplace, I get nothing but ‘download unsuccessful’ messages.
Update later – aah, the Spotify Mobile page now has a direct download link for the app, and specifically mentions the G1 dev phone. Interesting.
adb install -r ~/Downloads/SpotifyAndroid.apk will install the app, assuming you have the Android dev tools installed.
