I'm doing a project on Android Studio and I've got a problem:
I have changed the volume of the media in one activity and I've tried to move the media to the second activity.
I've succeded to move the audio to the second activity but it was without any volume change...
How can I fix it?
update:
Hi, because I can't save the changes that I have made in my mediaPlayer I decided to record the song before I moving between the activitys.
I got a problem with the mediaRecorder - I can't start recording and I have no idea what is wrong in my code...
my code:
rec.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(secondRemix.this, "You are starting the recording, you need to wait a little bit until it will be ready.",
Toast.LENGTH_SHORT).show();
FILE = Environment.getExternalStorageState()+"/tempRecord.3gpp";
record.setAudioSource(MediaRecorder.AudioSource.MIC);
record.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
record.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
record.setOutputFile(FILE);
record.start();//check it!!!
song.start();
startActivity(new Intent(secondRemix.this,waitScreen.class));
record.stop();
record.release();
can anybody help me with that? –
Thank you!
Is not a properly answer but might help. Short: you can't.
Why?
The native Media Player uses canvas to render the frames and it is automatic cleaned when is not on the screen.
Workaround 1: When you start the video on the new Activity automatically start from the position that the user stopped.
Workaround 2 (Like Youtube): Use fragments to manage your view.

I am working on a simpel game and I would like to have a video background. I first did this using a gif but this runs kind of slow. Now I created a video background using the mediaplayer and it works perfectly.
The video show without a problem.
The only problem I have is that the video does not want to loop. I tried every single aproache i found on the internet but nothing seems to work.
The video always plays 1 time and then stops.
I am using the java JDK8. Windows 10, 64 bit.
This is my code:
Media media = new
Media(getClass().getClassLoader().getResource("img/menu.mp4").toString());
MediaPlayer player = new MediaPlayer(media);
player.setAutoPlay(true);
player.setCycleCount(MediaPlayer.INDEFINITE);
MediaView view = new MediaView(player);
All of this is inside a stackpane.
I have tried exporting the mp4 to flv but this does not work.
If anyone knows different ways to create a video background, everything is welcome.
Edit:
So far no luck, I was thinking of using:
player.setOnEndOfMedia(new Runnable() {
#Override
public void run() {
player.seek(Duration.ZERO);
}
});
But not even this works..
Probably it's a bit late but you forgot to play after seeking to duration zero.
player.setOnEndOfMedia(new Runnable() {
#Override
public void run() {
player.seek(Duration.ZERO);
player.play();
}
});
It worked for me
From the MediaPlayer API:
Media playback commences at startTime and continues to stopTime. The interval defined by these two endpoints is termed a cycle with duration being the difference of the stop and start times. This cycle may be set to repeat a specific or indefinite number of times.
So you need to set startTime and stopTime before cycling works. For example (for a 5 second video):
player.setStartTime(Duration.seconds(0));
player.setStopTime(Duration.seconds(5));
Just to be clear, because my question can be not so clear.
I develop Music Player app. The thing is I have MainActivity and 4 Fragments in this activity(it's not all).
In each fragment I have list of songs retrieved from device using CustomCursorAdapter(for example: first fragment - all songs, second fragment albums e.t.c.)
I already tried to use MediaPlayerSingleton
public class singletonMediaPlayer{
MediaPlayer mediaPlayer;
private static singletonMediaPlayer in = null;
private singletonMediaPlayer() { }
public static singletonMediaPlayergetInstance() {
if (in == null) {
synchronized (singletonMediaPlayer.class) {
if (in == null) {
in = new singletonMediaPlayer();
}
}
}
return instance;
}
}
But here the problem was that all playback controls I have in MainActivity(not in fragments) and have no idea how to handle previouse, next buttons. It is not a problem if media player is in fragment or activity together with ListView of songs but like this... have no idea. Plus when I tried to select item(song) from another activity it just didn't play until I press play button. Playbacks I can see it through all fragments so it's looks like this(just in case):
Plus I have 2 seperate Activities to show songs from albums and from playlists. Sooooooooooo... Finaly the question is:
How do you think it is better to build Media Player for such app (just in case, I don't need code from you). Is it better to use Music Service(which I already started to build) or maybe Singletone is better(in that case I just don't know how to perform the task with singletone for now) or maybe there is another way??? Will be great if somebody response with hint, link or just show me the way in which better to go.
Thank you in advance!
P.S.
Yep, by the way there are 3 ListViews with songs(for now) - 2 of them reusable.
I'm Developing Android Application for Parental Controlling, so I want to disable home and back button. Because kids are unpredictable, their can push home button or back button and so on. Than i want to disable sliding notification bar. (Because notification bar can change device configuration and setting)
I'm planning to create Android Application which is similar to the Samsung Kids Mode-Parental Control.
Is possible to create application like Samsung Kids Mode? Can you give some link/article or even example program to me?
I Have tried this :
#Override
public void onAttachedToWindow() {
this.getWindow().setType(WindowManager.LayoutParams.TYPE_KEYGUARD);
super.onAttachedToWindow();
}
but it not handle home button, the Home button still working.
Thanks in advance to everyone for taking time to read this, hoping a positive solution.
I dont know of anyway to override the home button. Im not sure that it can be done. You can override the back button like so.
#Override
public void onBackPressed() {
//do nothing, important dont call super.onBackPressed
}
Another this you can do is set the app to immersive mode to reduce the chance of accidently exiting the app
https://developer.android.com/training/system-ui/immersive.html
Extended from Activity
#Override
public void onBackPressed() {
}
can be used to override back button. Be sure to remove super.onBackPressed().
Been a lurker on this site to help find answers to some of my problems before, but I am currently stuck on this and could not find a recent solution. The closest answers I found to my problem were Yelp API Android Integration and Yelp Integration in Android
I tried following the steps in the 2nd link but they are a bit outdated. I have registered for an API, downloaded the jar files from the github and synced them, and made the YelpAPI.java and TwoStepOAuth.java files and removed the main method from YelpAPI. I am stuck on step 4 on the search part. I tried to call the queryAPI method from inside an onClick method I made for a button
public void getRandom(View view) {
Intent intent = new Intent(this, SecondActivity.class);
startActivity(intent);
YelpAPI.YelpAPICLI yelpApiCli = new YelpAPI.YelpAPICLI();
new JCommander(yelpApiCli);
YelpAPI yelpApi = new YelpAPI(CONSUMER_KEY, CONSUMER_SECRET, TOKEN, TOKEN_SECRET);
try {
YelpAPI.queryAPI(yelpApi, yelpApiCli);
} catch (JSONException e) {
e.printStackTrace();
}
}
Basically what I want this to do is, when the button is pressed, I want it to go to a second screen that will display what I query Yelp for. I haven't worked on that part yet, right now I just want to get a result back from Yelp. Keep in mind I am a complete noob at Android Studio and at most intermediate at Java.
Any help is greatly appreciated, it seems like its a really simple problem but its taking me forever to figure out on my own.
You can't do blocking task like downloading or image loading in android's Main thread (UI Thread). You can't block UI for more than 5 seconds. If you try it to block for more than 5 seconds than your app will stop working and display "Unfornutaley your app has stopped working" because of error too much work on main thread. So you need to make use of async task.
I've been using this code and it plays sound just fine on Froyo and Gingerbread (and I assume Honeycomb as well as my friends have used it):
MediaPlayer mp = MediaPlayer.create(this, R.raw.click);
Button clicker = (Button) findViewById(R.id.clicker);
clicker.setOnClickListener(new View.OnClickListener() {
public void onClick(View v){
mp.start();
}
});
The audio I'm using is in WAV format. I've checked it to make sure it's not corrupted and it's fine. This code and sound file still run correctly on Gingerbread.
On Ice Cream Sandwich and JellyBean devices (a galaxy nexus and a nexus 7 respectively) this code does not work. No sound is played. There's nothing put in logcat. I've searched through the Internet and asked my friends for ideas and I can't come up with anything.
Thank you in advance for your time!
Wrap the call in an IllegalStateException, run it thru the debugger and see what you are getting. Also set a boolean isPlaying=mp.isPlaying(); and check its value. Also try a mp.reset() before starting and see it it works.
Also see http://developer.android.com/reference/android/media/MediaPlayer.html#setOnErrorListener%28android.media.MediaPlayer.OnErrorListener%29
Go ahead and inplement MediaPlayer.OnErrorListener and register the method with the media player. See what error you get.
