我正在为一个项目构建原型。我希望能够将音乐从我的网站流式传输到应用程序。
这是我到目前为止所拥有的。尝试使用 m3u,因为老实说我不知道还能用什么。
Button buttonPlay;
Button buttonStop;
MediaPlayer mPlayer;
String url = "http://www.*******.com/*****/files.m3u";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
buttonPlay = (Button) findViewById(R.id.play);
buttonPlay.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
mPlayer = new MediaPlayer();
mPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
try {
mPlayer.setDataSource(url);
} catch (IllegalArgumentException e) {
Toast.makeText(getApplicationContext(), "You might not set the URI correctly! Illegal Argument", Toast.LENGTH_LONG).show();
} catch (SecurityException e) {
Toast.makeText(getApplicationContext(), "You might not set the URI correctly! Security ", Toast.LENGTH_LONG).show();
} catch (IllegalStateException e) {
Toast.makeText(getApplicationContext(), "You might not set the URI correctly! Illegal Statement", Toast.LENGTH_LONG).show();
} catch (IOException e) {
e.printStackTrace();
}
try {
mPlayer.prepare();
} catch (IllegalStateException e) {
Toast.makeText(getApplicationContext(), "You might not set the URI correctly! Prepare Illegal State", Toast.LENGTH_LONG).show();
} catch (IOException e) {
Toast.makeText(getApplicationContext(), "You might not set the URI correctly! Prepare IO", Toast.LENGTH_LONG).show();
}
mPlayer.start();
}
});
buttonStop = (Button) findViewById(R.id.stop);
buttonStop.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
if(mPlayer!=null && mPlayer.isPlaying()){
mPlayer.stop();
}
}
});
他们的问题是它在准备后抛出 IO异常。现在我在某处读到您必须下载 m3u 文件,然后逐行阅读它们。如果是这样的话,有没有更好的方法?我正在尝试制作一种用于测试目的的广播应用程序,该应用程序将随机播放歌曲,而不是按顺序播放,所以我不想对它们进行硬编码 MP3 文件,
您不能只准备一个流,因为它需要异步下载。 您将需要执行此操作
Button buttonPlay;
Button buttonStop;
MediaPlayer mPlayer;
String url = "http://www.*******.com/*****/files.m3u";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
buttonPlay = (Button) findViewById(R.id.play);
buttonPlay.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
mPlayer = new MediaPlayer();
mPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
try {
mPlayer.setDataSource(url);
} catch (IllegalArgumentException e) {
Toast.makeText(getApplicationContext(), "You might not set the URI correctly! Illegal Argument", Toast.LENGTH_LONG).show();
} catch (SecurityException e) {
Toast.makeText(getApplicationContext(), "You might not set the URI correctly! Security ", Toast.LENGTH_LONG).show();
} catch (IllegalStateException e) {
Toast.makeText(getApplicationContext(), "You might not set the URI correctly! Illegal Statement", Toast.LENGTH_LONG).show();
} catch (IOException e) {
e.printStackTrace();
}
try {
mPlayer.prepareAsync();
mPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
@Override
public void onPrepared(MediaPlayer mp) {
mPlayer.start();
}
};);
} catch (IllegalStateException e) {
Toast.makeText(getApplicationContext(), "You might not set the URI correctly! Prepare Illegal State", Toast.LENGTH_LONG).show();
} catch (IOException e) {
Toast.makeText(getApplicationContext(), "You might not set the URI correctly! Prepare IO", Toast.LENGTH_LONG).show();
}
}
});
buttonStop = (Button) findViewById(R.id.stop);
buttonStop.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
if(mPlayer!=null && mPlayer.isPlaying()){
mPlayer.stop();
}
}
});
