Question

可能重复：
MediaPlayer unable to prepare?

标题说明了一切。我写了一个流媒体广播应用程序，它在功能上相当基本，但有些设备拒绝“准备”，例如我的Optimus One运行2.2。我的应用程序在其他2.2设备上运行，任何我兄弟的S2运行2.3和我的Prime运行4.0.3。

知道为什么我的具体设计不会准备音频吗？

下面添加了一些代码

private void togglePlay() {
    try {
        if(!this.player.isPlaying()) {
            this.player.setAudioStreamType(AudioManager.STREAM_MUSIC);
            this.player.setDataSource(this.address);
            this.player.prepareAsync();
        } else {
            this.player.reset();
        }
    } catch (IllegalArgumentException e) {
        ;
    } catch (IllegalStateException e) {
        ;
    } catch (IOException e) {
        ;
    }
}
