I am working on an app with recorder and player. I am using mediaplayer to play the recorded .wav file and meantime I want to update to a seekbar. Everything is working fine But my problem is mediaplayer progress updation to seekbar is not happening smoothly, If we are playig a small file, thumb of the seekbar jumps in seconds or between.
Can anyone help me with a workaround to make it smooth seeking of the progress in seekbar. My code is shown below.I am totlay stuck here.
mediaPlayerIntiate();
mediaPlayerSetSource();
mMediaPlayer.start();
task = new TimerTask() {
@Override
public void run() {
Graphbar.post(new Runnable() {
@Override
public void run() {
if (mMediaPlayer != null) {
if (playButtonState == MediaMode.PLAY) {
if (mMediaPlayer.isPlaying()) {
Graphbar.setProgress(mMediaPlayer
.getCurrentPosition());
mediaPlayerUpdateTimer(mMediaPlayer
.getCurrentPosition());
enableRewindandForward();
}
}
}
}
});
}
};
timer = new Timer();
timer.schedule(task, 0, 8);
mMediaPlayer.getCurrentPosition() Return current Time in millisecond and you are updating this to Seekbar which maximum capacity is 100. Make one formula to with length of file and 100. try this function
MediaPlayer mMediaPlayer = new MediaPlayer();
final SeekBar mSeelBar = new SeekBar(this);
final int duration = mMediaPlayer.getDuration();
final int amoungToupdate = duration / 100;
Timer mTimer = new Timer();
mTimer.schedule(new TimerTask() {
@Override
public void run() {
runOnUiThread(new Runnable() {
@Override
public void run() {
if (!(amoungToupdate * mSeelBar.getProgress() >= duration)) {
int p = mSeelBar.getProgress();
p += 1;
mSeelBar.setProgress(p);
}
}
});
};
}, amoungToupdate);
And this process should be called when Media player start playing. inside
mediaPlayer.setOnPreparedListener(new OnPreparedListener(){
@Override
public void onPrepared(MediaPlayer mp) {
**// call here**
}
});
Update
Update 125 times in seconds is not something you should do. Please increase your interval for updating SeekBar. I adding this after reading comments of NullPointer
