Playback position resets to zero after orientation change

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.

How can I check bluetooth LE ScanResult with android ble scanning app?

Hello I'm working on simple BLE scanning app with java but it doesn't work.
I referred https://github.com/benlc/ble, android developers and completed the source code.
import androidx.appcompat.app.AppCompatActivity;
import androidx.recyclerview.widget.LinearLayoutManager;
import androidx.recyclerview.widget.RecyclerView;
import android.bluetooth.BluetoothAdapter;
import android.bluetooth.BluetoothManager;
import android.bluetooth.le.BluetoothLeScanner;
import android.bluetooth.le.ScanCallback;
import android.bluetooth.le.ScanResult;
import android.content.Context;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.Toast;
import java.util.ArrayList;
import java.util.List;
public class MainActivity extends AppCompatActivity {
private Button btnScanAdvStart;
private ArrayList<ItemDevice> arrayList;
private LeDeviceListAdapter leDeviceListAdapter;
private RecyclerView recyclerViewDevice;
private LinearLayoutManager linearLayoutManager;
private BluetoothAdapter mBluetoothAdapter;
private BluetoothLeScanner mBluetoothLeScanner;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
btnScanAdvStart = findViewById(R.id.btn_start);
recyclerViewDevice = findViewById(R.id.rv_device);
linearLayoutManager = new LinearLayoutManager(this);
recyclerViewDevice.setLayoutManager(linearLayoutManager);
arrayList = new ArrayList<>();
leDeviceListAdapter = new LeDeviceListAdapter(arrayList);
recyclerViewDevice.setAdapter(leDeviceListAdapter);
final BluetoothManager bluetoothManager = (BluetoothManager) getSystemService(Context.BLUETOOTH_SERVICE);
mBluetoothAdapter = bluetoothManager.getAdapter();
btnScanAdvStart.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
startReceiving();
}
});
}
#Override protected void onDestroy() {
super.onDestroy();
stopReceiving();
}
private ScanCallback mScanCallback = new ScanCallback() {
#Override
public void onScanResult(int callbackType, ScanResult result) {
super.onScanResult(callbackType, result);
ItemDevice item = new ItemDevice(
result.getDevice().getName(),
result.getDevice().getAddress(),
result.getRssi(),
result.getTimestampNanos());
arrayList.add(item);
leDeviceListAdapter.notifyDataSetChanged();
}
#Override
public void onBatchScanResults(List<ScanResult> results) {
super.onBatchScanResults(results);
}
#Override public void onScanFailed(int errorCode) {
super.onScanFailed(errorCode);
Toast.makeText(MainActivity.this, "Scan fail", Toast.LENGTH_SHORT).show();
}
};
private void startReceiving() {
mBluetoothLeScanner = mBluetoothAdapter.getBluetoothLeScanner();
mBluetoothLeScanner.startScan(mScanCallback);
}
private void stopReceiving() {
mBluetoothLeScanner.stopScan(mScanCallback);
}
}
also permission is added in manifest file
<uses-permission android:name="android.permission.BLUETOOTH"/>
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
I want to know why it isn't work and how to make it work. I checked ScanResult with toast message but it does not show any result...

That's a very old example. Nowadays Android needs runtime permissions for ACCESS_FINE_LOCATION. See https://developer.android.com/training/permissions/requesting for a tutorial.

Sound cannot be played in the emulator

I have set a sound in a "raw" file. However, when I put everything together, the original click sound on emulator is playing but my "mouse click" sound is not.
I have my mouse click sound set to "sound1".
The sound is only 1 second long I do not know if that matters.

Looks like you have implemented an onClick in your XML, as well as setOnClickListener in your Java.
So as far as I can tell, your code is running the onClickListener which is starting your openActivity2() method, and skipping the playSound() method.
Try removing the onClick in your XML and integrating playSound() into the setOnClickListener instead.
You could also add in AudioFocus request.
This code works: In my case I have used a fragment class but this can be used in any activity.

import androidx.annotation.Nullable;
import androidx.fragment.app.Fragment;
public class fragment1 extends Fragment {
//These are the declarations
Button btn;
MediaPlayer mMediaPlayer;
private AudioManager mAudioManager;
//This tells the media player what to do if AudioFocus is changed
private AudioManager.OnAudioFocusChangeListener
mOnAudioFocusChangeListener =
new AudioManager.OnAudioFocusChangeListener() {
#Override
public void onAudioFocusChange(int focusChange) {
if (focusChange == AudioManager.AUDIOFOCUS_LOSS_TRANSIENT ||

mMediaPlayer.seekTo(0);
} else if (focusChange == AudioManager.AUDIOFOCUS_GAIN){
mMediaPlayer.start();
}else if (focusChange == AudioManager.AUDIOFOCUS_LOSS){
releaseMediaPlayer();
}
}
};
//This tells the media player what to do when the playback is done
private MediaPlayer.OnCompletionListener mOnCompletionListener = new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
releaseMediaPlayer();
}
};
#Nullable

public View onCreateView(#NonNull LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.**YOUR LAYOUT HERE**,container,false);
//This assigns the audio manager to this view

AudioManager.STREAM_MUSIC, AudioManager.AUDIOFOCUS_GAIN_TRANSIENT);
//This if statement deals with the above request
if (result == AudioManager.AUDIOFOCUS_REQUEST_GRANTED){
