android-mediaplayer

问题 I am streaming live audio and wish to have the functionality to pause the mediaplayer and then start from the current live position. The default Pause() and Start() just starts from where it was stopped. Any ideas on how to keep the current position updated so that Start() is instant? 回答1: Did you try calling seekTo()? You could keep it pemanently updated by calling seekTo() every half a second or so with TimerTask, But i don't know how i feel about this. EDIT: If you call seekTo() every 500

问题 I'm trying to play audio file from Firebase storage in my application. I wrote code exactly same from the youtube video about this, but it doesn't play a song. Can anybody tell what is the problem? I tried pretty many solutions in some questions such as missing permission in Manifest, relocation of MediaPlayer methods etc. Nothing worked. public void play_Song(View view) { final MediaPlayer mediaPlayer = new MediaPlayer(); try { mediaPlayer.setDataSource( url ); mediaPlayer.prepare();

问题 I have in connection a seekbar and a button alone used for play / pause. the principle is functional, when i press the button, it starts to play and in a second time when i press it pauses mediaplayer (perfect). The problem is when I press again so that it continues reading, the reading starts again from the beginning instead of continuing from the place where it had been paused. Please direct me, here is my code : PLAY_SONG private void play_songs() { mediaPlayer = new MediaPlayer(); if

问题 I wrote a class that shall make it possible to record an audio, save it to the sd card and then play the result. Here is my code: public void recordAudio(final String fileName) { final MediaRecorder recorder = new MediaRecorder(); recorder.reset(); ContentValues values = new ContentValues(3); values.put(MediaStore.MediaColumns.TITLE, fileName); recorder.setAudioSource(MediaRecorder.AudioSource.MIC); recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP); recorder.setAudioEncoder

问题 This is the code I use to save the string representation of the Uri to the SharedPreferences: public void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); if (requestCode == REQ_CODE_PICK_SOUNDFILE && resultCode == Activity.RESULT_OK){ if ((data != null) && (data.getData() != null)){ SharedPreferences sharedPref = getSharedPreferences("customName", Context.MODE_PRIVATE); SharedPreferences.Editor editor = sharedPref.edit();

问题 So for an app I'm developing I have a bunch of audio files that, depending on the state of some variables, may or may not play (and the order in which they play can change as well). I understand the basics of the setOnCompletionListener , but I can't figure out the best way to use it. As of right now, if I want to play audio1, audio2, then audio3, my code is set up as follows: clipSetup(1); aP.setOnCompleteListener(new MediaPlayer.OnCompletionListener(){ @Override public void onCompletion

问题 I'm trying to figure out how to delay an audio file by about 15 seconds. The audio file is 5 seconds long and it's a sound effect saying "5,4,3,2,1 go!", the countdown is from 20 so it should start after 15 seconds. I heard I can do this with a handler but I don't know how to implement it in the code, so here it is, help would be much appreciated! I edited it with the way below, however now the player doesn't start at all, here's the new code: public class WorkoutGymEasy1 extends Activity {

问题 I am working on an application which displays videos from Nodejs& MongoDB server. The problem here is because the videos are not streaming, mediaPlayer on Android fully downloads video and then displays it and this is really slow as you can guess. I am not a native speaker so reading documents mostly hard to understand for me. Which path should I go? RTSP or HTTP streaming. Any tips how can I achieve my goal? All your help is appreciated, best regards. 回答1: While dedicated streaming servers
