I am developing a media player app that has a bound service to an activity.It works fine when i press the home button or the app switcher and then come back to the app from the recent app, but as i press the back button the activity also ends the Music Service. Please guide me the exact steps that can solve these minor issues, so that i can give media controls to the app.My App has 2 main classes
MyActivity
AudioService
My code is given below.
AudioService.java
public class AudioService extends Service implements
MediaPlayer.OnPreparedListener, MediaPlayer.OnErrorListener,
MediaPlayer.OnCompletionListener{
// -----------------------------------------Attributes--------------------------------------------------------

// -----------------------------------------------------------------------------------------------------------

public void onCreate(){
//create the service
//create the service
super.onCreate();
//initialize position

//create player
player = new MediaPlayer();
initMusicPlayer();
}
// to initialize the media class

i'm make mp3 player offline, in the MainActivity there is a song list when an item is clicked it will send the song data with intent to PlayActivity. I want when another song is clicked then the current song is paused. What should i do? below is my code
MainActivity
public class MainActivity extends AppCompatActivity {
//deklarasi variabel -->
MediaPlayer mediaPlayer;
ListView listView;
final String[] song_name = { "intuisi", "krisis solusi" };
final int[] ResID = {R.raw.intuisi, R.raw.krisis};
ImageView img_play;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//inisialisasi variabel
mediaPlayer = new MediaPlayer();
listView = findViewById(R.id.list_item);
//make adapter for listview
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, song_name);
listView.setAdapter(adapter);
//onClick item
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
playSong(i);
}
});
}
private void playSong(int songIndex) {
//send song data to playActivity
Intent intent = new Intent(MainActivity.this, Play.class);
intent.putExtra("song", ResID[songIndex]);
startActivity(intent);
}
PlayActivity
int Nama = getIntent().getIntExtra("song",0);
mediaPlayer = MediaPlayer.create(getApplicationContext(), Nama);
if (mediaPlayer != null && mediaPlayer.isPlaying()) {
mediaPlayer.pause();
} else {
mediaPlayer.start();
}
You can create a separate singleton helper class for handling your music player with some contextual method like play, pause, stop etc.
public class MusicHelper {
private static MusicHelper instance;
MediaPlayer mPlayer;
private MusicHelper() {
instance = new MusicHelper();
}
public static MusicHelper getInstance() {
return instance;
}
public void init(Context ctx, int nama) {
mPlayer = MediaPlayer.create(getApplicationContext(), nama);
}
public void play() {
if (mPlayer != null && !mPlayer.isPlaying()) {
mPlayer.start();
}
}
public void pause() {
if (mPlayer!= null && mPlayer.isPlaying()) {
mPlayer.pause();
}
}
}
Then in your PlayActivity,
MusicHelper musicHelper = MusicHelper.getInstance();
musicHelper.init(getApplicationContext(), Nama);
musicHelper.play();
When clicked on another item, again fetch the helper instance and call pause.
private void playSong(int songIndex) {
MusicHelper musicHelper = MusicHelper.getInstance();
musicHelper.pause();
Intent intent = new Intent(MainActivity.this, Play.class);
intent.putExtra("song", ResID[songIndex]);
startActivity(intent);
}

When the Full Screen is visible and if the user clicked back, I want my Activity to be displayed. Instead what is happening now is the back button exists from the app.
How can I fix this?
UPDATE
I Identified the error, inside the setOnFullScreenListener it was never identified the app is in Full screen, even though it is. I tried forcing the boolean into true, but it ended up crashing saying the player is null
I'm not sure but in your onFullScreen() override method, you have set
isFullScreen = true;
Rather, use
isFullScreen = b;
Hope this helps.
I found the answer, just remove the if condition in onInitializationSuccess. Below is the code.
public class MainActivity extends AppCompatActivity implements YouTubePlayer.OnInitializedListener {
private static final int RECOVERY_REQUEST = 1;
private YouTubePlayerView youTubeView;
private YouTubePlayerFragment youTubePlayerFragment;
private YouTubePlayer player;
private boolean isFullScreen;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// youTubeView = (YouTubePlayerView) findViewById(R.id.youtube_view);
// youTubeView.initialize(Config.YOUTUBE_API_KEY, this);
youTubePlayerFragment = (YouTubePlayerFragment) getFragmentManager()
.findFragmentById(R.id.youtube_fragment);
youTubePlayerFragment.initialize(Config.YOUTUBE_API_KEY, this);
}
#Override
public void onInitializationSuccess(Provider provider, YouTubePlayer player, boolean wasRestored) {
this.player = player;
this.player.cueVideo("fhWaJi1Hsfo"); // Plays https://www.youtube.com/watch?v=fhWaJi1Hsfo
// player.setPlayerStyle(YouTubePlayer.PlayerStyle.CHROMELESS);
this.player.setOnFullscreenListener(new YouTubePlayer.OnFullscreenListener() {
#Override
public void onFullscreen(boolean b) {
isFullScreen = b;
}
});
}
#Override
public void onInitializationFailure(Provider provider, YouTubeInitializationResult errorReason) {
if (errorReason.isUserRecoverableError()) {
errorReason.getErrorDialog(this, RECOVERY_REQUEST).show();
} else {
String error = String.format(getString(R.string.player_error), errorReason.toString());
Toast.makeText(this, error, Toast.LENGTH_LONG).show();
}
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == RECOVERY_REQUEST) {
// Retry initialization if user performed a recovery action
getYouTubePlayerProvider().initialize(Config.YOUTUBE_API_KEY, this);
}
}
protected Provider getYouTubePlayerProvider() {
return youTubeView;
}
#Override
public void onBackPressed() {
if(isFullScreen)
{
Toast.makeText(this,"Full Screen",Toast.LENGTH_LONG).show();
player.setFullscreen(false);
}
else
{

Im making a simple radio streaming app. Everything works great but having a few buggy issues.
When i press the home screen of my device i want the radio to carry on playing. which it does, But as soon as i go to my app history and re-open the app. It starts a new session. this make for a very Un-Pleasurble piece of music lol.
The app is very simple in the way it works i have a media player and a media controller which is attached to a surfaceView in my xml.
Can some one please tell me the correct way to fix this issue as this is the first time making an app that contains a live stream.
Thanks as always guys

MediaController requires the context to be passed to the constructor. Without anymore code or knowing where you declared the MediaController, my best guess is that you don't have access to the context in the place where you declared the MediaController. Either pass the context from the activity where you would like to use the MediaController, or put this code in that activity.
https://developer.android.com/reference/android/widget/MediaController.html
EDIT:
I tried your code, check your imports & ensure you have, import android.widget.MediaController & not import android.media.session.MediaController.
Try this
if you are using in Activity then you can pass this
if you are using in Fragment then use getActivity() or context
and to set MediaController
use this code
video.setOnPreparedListener(new OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
mp.setOnVideoSizeChangedListener(new OnVideoSizeChangedListener() {
#Override
public void onVideoSizeChanged(MediaPlayer mp, int width, int height) {
/*
* add media controller
*/
mc = new MediaController(YourActivity.this);
video.setMediaController(mc);
/*
* and set its position on screen
*/
mc.setAnchorView(video);
}
});
}
});
I've implemented a RecyclerView which has a user interface of a timer counting down. I created a BroadcastService class which creates a CountDownTimer and broadcasts the timer's contents in the onTick() method to my MainActivity, where I use a BroadCast receiever to update the UI.
My BroadcastReceiver is only receiving the initial value from the BroadcastService. I figured that's because I hadn't notified the recycler view's adapter that the data had changed. However, because of variable scope, I'm unable to access my adapter from my broadcast receiver.
Perhaps I have a fundamental lack of understanding of variable scope, but how can I access the adapter from
adapter = new DataAdapter(getApplicationContext(), data);
in my broadcast receiver class? Because right now it's not being recognized.
This is my class definition + onCreate()
public class Profile_Page extends ActionBarActivity implements DataAdapter.ClickListener {
private RecyclerView recyclerView;
public DataAdapter adapter;
private Context context;
String currentUser;
Data current = new Data();
final List<Data> data = new ArrayList<>();
public static String BROADCAST_ACTION =
"packagename.countdown_br";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
IntentFilter filter = new IntentFilter();
filter.addAction(BROADCAST_ACTION);
filter.addCategory(Intent.CATEGORY_DEFAULT);
registerReceiver(br, filter);
startService(new Intent(this, Broadcast_Service.class));
setContentView(R.layout.activity_profile__page);
ParseQuery<ParseObject> query = ParseQuery.getQuery("ParseClass");
query.whereEqualTo("author", ParseUser.getCurrentUser());
recyclerView = (RecyclerView) findViewById(R.id.recyclerView);
recyclerView.setLayoutManager(new LinearLayoutManager(this));
query.findInBackground(new FindCallback<ParseObject>() {
#Override
public void done(List<ParseObject> list, ParseException e) {
if (e == null) {
for (ParseObject getData : list)
{
current.1= getData.getString("1");
current.2= getData.getString("2");
current.3= getData.getString("3");
current.4= getData.getString("4");
current.5= getData.getString("5");
data.add(current);
}
}
else {
}
adapter = new DataAdapter(getApplicationContext(), data);
recyclerView.setAdapter(adapter); //set recyclerView to this adapter
}
});
}
And here's my Broadcast Receiver code [which is also in MainActivity.java]
public BroadcastReceiver br = new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
updateGUI(intent);
//HOW TO NOTIFY DATA SET CHANGE
}
};
public void updateGUI(Intent intent) {
if (intent.getExtras() != null) {
long millisUntilFinished = intent.getLongExtra("countdown", 0);
current.goalTimer = String.valueOf(intent.getExtras().getLong("countdown") / 1000);
}
}
And, if it is of any use, here's my Broadcast Service class:
public class Broadcast_Service extends Service {
private final static String TAG = "BroadcastService";
LocalBroadcastManager broadcastManager;
public static final String COUNTDOWN_BR = "packagename.countdown_br";
Intent bi = new Intent(COUNTDOWN_BR);
CountDownTimer cdt = null;
#Override
public void onCreate() {
super.onCreate();
Log.i(TAG, "Starting timer...");
cdt = new CountDownTimer(30000, 1000) {
#Override
public void onTick(long millisUntilFinished) {
bi.putExtra("countdown", millisUntilFinished);
sendBroadcast(bi);
}
#Override
public void onFinish() {
Log.i(TAG, "Timer finished");
}
};
cdt.start();
}
#Override
public void onDestroy() {
cdt.cancel();
Log.i(TAG, "Timer cancelled");
super.onDestroy();
}
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
return super.onStartCommand(intent, flags, startId);
}
#Override
public IBinder onBind(Intent intent) {
return null;
}
}
First of all, extend the BroadcastReciever class as follows:
public class MyReciever extends BroadcastReciever{
private Profile_Page activity;
public MyReciever(Profile_Page activity){
this.activity = activity;
}
#Override
public void onReceive(Context context, Intent intent) {
activity.updateGUI(intent);
}
}
Create a static instance of your activity and pass it to your receiver.
public class Profile_Page extends ActionBarActivity implements DataAdapter.ClickListener {
private static Profile_Page instance;
private MyReciever myReceiver;
...
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
instance = this;
myReceiver = new MyReciever(instance);
...
}
public void updateGUI(Intent intent) {
...
}
}
Now you can access your adapter quite easily. Hope this helps.
