我遇到了这个问题，音频只是不想播放。没有错误，但是当我应该听到音乐时，我听不到音乐。这是下面的代码和logcat。我不知道如何阅读 logcat，这可能有助于解决问题。
public void start1(final View view)
{
setContentView(R.layout.timer);
if(path1.equals("default"))
{
path1="R.raw.iwilltouchthesky.mp3";
}
mp.reset();
try {
mp.setDataSource(path1);
} catch (IllegalArgumentException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
mp.start();
text = (TextView) this.findViewById(R.id.textView1);
text2 = (TextView) this.findViewById(R.id.textView3);
a=new CountDownTimer(interval1*1000, 1000) {
public void onTick(long millisUntilFinished) {
text.setText("Seconds Remaining: " + (millisUntilFinished / 1000));
text2.setText("Repetitions Left: "+repsleft);
}
public void onFinish() {
mp.stop();
start2(view);
}
}.start();
}
