Android :: Calling The Stop() Function Of MediaPlayer
Aug 22, 2010
I see calling the stop function of MediaPlayer simply does nothing. The playback goes on.
I looked in the documentation and I found: "Stops playback after playback has been stopped or paused."
So, I tried to pause() it before stopping, but the MediaPlayer then pauses and resumes the playback. The only thing I can see is that the buffering stops. But the playback continues. Is this the expected behavior? Could the problem be related to the fact that I call the methods of the MediaPlayer object from different threads than the creator by synchronizing with Semaphores?

I have a requirement to play several sounds many times in my game so instead of creating the MediaPlayer again and again I have called mp.seekTo(0) in onCompletion(mp) so that it will restart. Sometimes the sound is not audible from the device when I call mp.start () after setting mp.seekTo(0); but the player calls onCompletion() without playing any sound, this is observed randomly on most of the sounds
My sounds are of short duration mostly less than a second.
I am using a separate MediaPlayer for each sound (as I need this) -
There are almost 28 sounds in my game so i will be creating 28 MediaPlayers.
Below is the attached code for player
Also If I try to play many sounds one after the other in a short period of time i get an error saying "no more track names available". can u tell Why this is happening...?
check the below code:

I have a SMSReceiver class that needs to pass the phone number and message to another class. Which works but when I call that class I need the function to read preference to compare if it needs to execute another function.

Is there a way to hide my phone number when calling out? I came over from BlackBerry, where there is simply an option to "hide" my phone number on outgoing calls... but I can't seem to do this with my Eris. Someone once suggested that I prefix my contacts with *69... but that seems to prevent caller id from working properly, which just trades one issue for another.
If possible, I would prefer to be selective with who I do this with (it's okay for personal contacts to see my number... but it's not okay for business contacts to see my number).

I'm playing around with the MediaPlayer class to reproduce some sounds/music. I am playing raw resources (res/raw) and it looks kind of easy.
To play a raw resource, the MediaPlayer has to be initialized like this:
CODE:.................
Until here there is no problem. The sound is played, and everything works fine. My problem appears when I want to add more options to my application. Specifically when I add the "Stop" button/option.
Basically, what I want to do is...when I press "Stop", the music stops. And when I press "Start", the song/sound starts over. (pretty basic!)
To stop the media player, you only have to call stop(). But to play the sound again, the media player has to be reseted and prepared.
CODE:...............
The problem is that the method setDataSource() only accepts as params a file path, Content Provider URI, streaming media URL path, or File Descriptor.
So, since this method doesn't accept a resource identifier, I don't know how to set the data source in order to call prepare(). In addition, I don't understand why you can't use a Resouce identifier to set the data source, but you can use a resource identifier when initializing the MediaPlayer.
I guess that I'm missing something. I wonder if I am mixing concepts, and the method stop() doesn't have to be called in the "Stop" button.

I am calling a method of another .apk file dynamically at runtime in my application. I can execute it successfully if method does not contain any variable which is defined outside of that method.
But if I am using the variables which are defined outside that method ( in the same activity or same .apk) then my application throws "java.lang.reflect.InvocationTargetException" at runtime.
For e.g. if method defines as ,

I have a activity which is called from another activity as an intent... This activity loads and starts playing a audio file. All is good - that much works. The activity also has a "stop" button and that stops the audio from playing - that is also fine.
But how do I stop the file from playing if the user uses the back button to leave the activity without clicking on the "Stop" button?

So ya, there's a phone in my HTC Hero. No surprise.
My problem is this:
I find that the easiest way to call a person is to go to the phone app and scroll through the call history displayed to find the person I wish to call. Once I see their name, I just press on it, and the call begins. Unfortunately, a friend I call often may use their house phone or cell phone when I only ever want to call their cell (Evo ). Often, the situation is that I previously talked to him on his house phone, and I'm calling him in the middle of the night (we're young; we don't sleep rational hours during the summer... or ever). Unfortunately for me, my call usually bugs his parents, and I get reprimanded...
Is there a setting that allows me to only call his cell, or do I just need to break this habit?

I am trying to call my service class's stopService() method from my activity. But I don't know how to access stopservice method from my activity class. I have the below code but its not working. This is HomeScreen class:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
enablecheck = (CheckBox)findViewById(R.id.enablecheck);
enablecheck.setOnCheckedChangeListener(new OnCheckedChangeListener(){
@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
// TODO Auto-generated method stub
if(enablecheck.isChecked()){
startService(new Intent(HomeScreen.this, AutoService.class));
} else {
stopService(new Intent(HomeScreen.this, AutoService.class));
} } });
}
This is Service Class:
public class AutoService extends Service {
private static final String TAG = "AutoService";
private Timer timer;
private TimerTask task;
@Override
public IBinder onBind(Intent intent) {
return null;
} @Override
public void onCreate() {
Toast.makeText(this, "Auto Service Created", Toast.LENGTH_LONG).show();
Log.d(TAG, "onCreate");
int delay = 5000; // delay for 5 sec.
int period = 5000; // repeat every sec.
timer = new Timer();
timer.scheduleAtFixedRate(task = new TimerTask(){
public void run() {
System.out.println("done");
} }, delay, period);
}
@Override
public boolean stopService(Intent name) {
// TODO Auto-generated method stub
timer.cancel();
task.cancel();
return super.stopService(name);
} }

I have a ListView displaying images on every element of the ListView, It works fine... but when I start to scrolling I have realized my image is downloaded again if it is displayed in the screen of my phone device!
How could I stop reloading the images or all the content of the in ListView again?
Or how could I avoid reading the getView() function again If I have already downloaded all its content?

Had a few days of use without issues, go to make a call yesterday and it takes ages to connect, but instead of connecting I get a beep and then it returns me to my contact list. Tried putting the phone in and out of flight mode by holding down the power button and selecting the flight mode option, the option turns grey after I press it, won't allow me to press it again and seemingly does nothing. Press the off option and turn the phone back on and it's fine. Now I reckon I had suffered this with earlier firmwares.

In 1.6 I do the following to stream an mp3 shoutcast stream:
CODE:...........
This works great. However, I have to support phones running 1.5 as well. When I build against the 1.5 libraries and run in a level 3 emulator, I get an exception on the prepare() call with the message: Prepare failed.: status=0x1.
Is this supported in 1.5. Is there some other mechanism I have to use that will work in both?

I have such code:..............
When my sound played for the first time, it's all fine. But when for second, third, etc.. it sounds like cutted, just little part of my "click.wav". If I put there sound in another format like mp3 or ogg - all just fine.
Or if I write like this: mp_click = MediaPlayer.create(CubeTest_Main.Context, R.raw.click); mp_click.start(); All if fine too, but this is a bit slow, becouse this sound is playing very often.

I am developing a media player application which downloads from internet and plays. so while downloading I want to show a progress bar saying "buffering...", and while playing I want to dismiss the same progress bar. I can display the progress bar while downloading (by implementing the listener onBufferedUpdateListener), how can I get the event for player while it is playing.

I am developing a media player which will download the media content from network (Shoutcast) It works fine. Problem is a small gap between players (2 players) I am using two mediaplayers to play the data while a thread downloads and stores the data and stores in to 100Kb files continuously. on first players oncompletelistener() i started the second player wise versa. I think there is a problem with mp3 frames(header sync byte) while splitting 100kb files. how to resole the gap between players.

I know this question has been asked previously because I have read the other postings over a hundred times but yet I cannot come up with an answer on how to use keep a MediaPlayer object playing over an orientation change. I've read that you can use onRetainNonConfigurationInstance() to pass an object to your future self when the activity is destroyed/recreated, but I can't keep a video playing in this circumstances. Does anybody have an example or an advice/guide on how to do this? or rather what do I pass on onRetainNonConfigurationInstance() to keep the video playing after an orientation change?
