Below is the code for my music player. I use Videoview to play a local list of selective songs. I want to store and resume the playback position when orientation changes (portrait/landscape).
I have used onSaveInstanceState and onRestoreInstanceState methods. No errors on build, but still the songs reset every time.
I couldn't figure out what's wrong.
package io.automaton.android.morningbinge;
import androidx.appcompat.app.AlertDialog;
import android.app.Activity;
import android.content.DialogInterface;
import android.media.MediaPlayer;
import android.net.Uri;
import android.os.Bundle;
import android.widget.Toast;
import android.widget.VideoView;
import android.widget.MediaController;
import java.util.ArrayList;
public class MainActivity extends Activity
implements MediaPlayer.OnCompletionListener {
VideoView vw;
ArrayList<Integer> videolist = new ArrayList<>();
int currvideo = 0;
int mPositionWhenPaused=0;
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
vw = (VideoView)findViewById(R.id.videoView);
vw.setMediaController(new MediaController(this));
vw.setOnCompletionListener(this);
// video name should be in lower case alphabet.
videolist.add(R.raw.onbadhu_kolum);
videolist.add(R.raw.kala_bhairava_ashtakam);
videolist.add(R.raw.panchamukh_hanumath_kavacham);
videolist.add(R.raw.kandha_shashti_kavasam);
setVideo(videolist.get(0));
}
@Override
public void onSaveInstanceState(Bundle savedInstanceState) {
super.onSaveInstanceState(savedInstanceState);
//we use onSaveInstanceState in order to store the video playback position for orientation change
savedInstanceState.putInt("Position", vw.getCurrentPosition());
vw.pause();
}
@Override
public void onRestoreInstanceState(Bundle savedInstanceState) {
super.onRestoreInstanceState(savedInstanceState);
//we use onRestoreInstanceState in order to play the video playback from the stored position
mPositionWhenPaused = savedInstanceState.getInt("Position");
vw.seekTo(mPositionWhenPaused);
}
public void setVideo(int id)
{
String uriPath
= "android.resource://"
+ getPackageName() + "/" + id;
Uri uri = Uri.parse(uriPath);
vw.setVideoURI(uri);
vw.start();
}
public void onCompletion(MediaPlayer mediapalyer)
{
AlertDialog.Builder obj = new AlertDialog.Builder(this);
obj.setTitle("Playback Finished!");
obj.setIcon(R.mipmap.ic_launcher);
MyListener m = new MyListener();
obj.setPositiveButton("Replay", m);
obj.setNegativeButton("Next", m);
obj.setMessage("Want to replay or play next video?");
obj.show();
}
class MyListener implements DialogInterface.OnClickListener {
public void onClick(DialogInterface dialog, int which)
{
if (which == -1) {
vw.seekTo(0);
vw.start();
}
else {
++currvideo;
if (currvideo == videolist.size())
currvideo = 0;
setVideo(videolist.get(currvideo));
}
}
}
}
I sorted out the issue. I changed the way the list is being called to play with the setOnPreparedListener, seeking to last played position.
