问题 I have been trying to stream a URL using ExoPlayer . The URLs: STREAM_URL_1 = "http://storage.googleapis.com/exoplayer-test-media-0/play.mp3" STREAM_URL_2 = "https://s3-ap-southeast-1.amazonaws.com/ok.talk.channels/zakirkhan/Zakir+khan+-+when+my+father+took+my+gf%27s+call.aac" Both URLs play but I am not able to get the getDuration() for STREAM_URL_2 which is an .aac file. The .mp3 works. The following is how I do it. How do I get the getDuration() for the 2nd URL. Even seekTo() doesn't work

问题 I make a app with a ListView . When I tap on a ListView item, a .ogg soundfile should start playing. Not in my app, but in the default music player app of the user. How can I do this? 回答1: Try this Intent it = new Intent(Intent.ACTION_VIEW); Uri uri = Uri.parse("file:///sdcard/song.mp3"); it.setDataAndType(uri, "audio/mp3"); startActivity(it); Or Uri uri = Uri.withAppendedPath(MediaStore.Audio.Media.INTERNAL_CONTENT_URI, "1"); Intent it = new Intent(Intent.ACTION_VIEW, uri); startActivity(it)

问题 How to change the duration of the audiotrack by an infinite loop? I understand that I must apply the following line before audioTrack.play() : audioTrack.setLoopPoints (0, generatedSnd.length, -1); For example, I want the duration will be half a second, therefore, the "duration" variable of type "int" isn't valid. To do so I want the sound to play repeatedly and control the time to stop with a Timer. The code is: private int duration = 1; // seconds private int sampleRate = 44100; private

问题 I would like to add music controls such as play/pause, next, and back as well as show a thumbnail and song title to the bottom of an application like in the Google music app. When the thumbnail or title is tapped on, I want to bring up a detailed view of song, including a seek bar. I am wondering what the best approach for this would be. Should I just add a relative layout the the bottom of my apps xml, and add on click listeners, or can this be accomplished simply with something like the

问题 I'm using the audio player tutorial from androidhive.info and in the SongsManager.java I'm trying to convert duration to minutes and seconds. I've managed to do it but I keep getting a NumberFormatException which I don't know how to deal with.

问题 I am testing equalizer in my Android Version 7.1.1 but it shows a Runtime Exception but It's perfectly working on below version 7.0. When I try to initialize equalizer : private static UUID EQUALIZER_UUID; mp = MediaPlayer.create(this, R.raw.a); mp.start(); if(hasEqualizer()) { equalizer = new Equalizer(0, mp.getAudioSessionId()); equalizer = equalizerUtil.getEqualizer(mp); Log.d("No. of Presets",String.valueOf(equalizer.getNumberOfPresets())); } public static boolean hasEqualizer() { for

问题 I'm going to create a simple Musicplayer for Android using Service. But I don't know the best way to save list of nowplaying. I used a database to store the list, but in this way, each time I start main player activity, I must read database and store to an array list and each time I update nowplaying, I must update the database. This way make waste of time and sometime data between Database and Arraylist is difficult to synchonized. What's the best way to solve this problem? - Store

问题 In my application, I need to launch the Android Music Player. And, for now, it works perfectly : Intent intent = new Intent(android.content.Intent.ACTION_VIEW); File file = new File(file_path); intent.setDataAndType(Uri.fromFile(file), "audio/*"); startActivity(Intent.createChooser(intent, "...")); But the user can't use the "next" and "prev" buttons to switch music. That's why I try to launch multiple songs at once (a playlist). And I don't really know how to do this! Give an array to the
