问题 I have got a UIViewController in my app with a UIWebView in it. The UIWebView is fixed-size and configured to open any links in a new UIViewController (browser).

问题 I'm using MediaPlayer to play a lot of short music in my app, but I got this warning in my logcat: MediaPlayer info/warning (973, 0). What does this warning mean? I searched around (in the documentation and on Google) but nothing comes up. Also, I released the MediaPlayer 'properly'. EDIT: 01-18 18:43:22.662: W/MediaPlayer(24940): info/warning (973, 0) 回答1: Good question, the codes are somewhat buried.
