I would like to create an ermergency call application : if triggered, it calls a given number and play an audio file, giving the information the caller couldn't give himself.For that I need to engage a call but ensure that I can replace any sound from the speaker with an played audio file. Can I do that in android ? What's the way?

I am working on a application that would allow users to play remote files. My question is how do I open those remote files to be played in the default android player?but this does not give me control of what is happening!
View 2 Replies View Relatedwhen I run this code, it starts playing all the audio files in the assets directory, in alphabetical order instead of just playing the audio file I requested. What am I doing wrong? Is there a better way to play audio files from the assets directory?Is there a difference between keeping audio files in the assets directory and keeping them in the res/raw directory? Besides the fact that they don't get ids if they are in the assets directory. If I move the audio files to the res/raw folder then I have a problem with reusing MediaPlayers because there is no id parameter for setDataSource(). I can't find a good guideline for handling this kind of problem.

View 2 Replies View RelatedI've got an activity that calls a helper class called DownloadManager. DownloadManager spawns a thread that downloads a mp3 to the sdcard. I'm having some trouble finding the best design for resuming the initial activity and starting the MediaPlayer. Does it make the most sense to use a BroadcastReceiver that receives a message that download is complete, then start a new Intent of my activity? Think I saw something that I can't use an Intent to start an Activity from BroadcastReceiver because it is a background process.

View 1 Replies View RelatedWhen you pick up the call and switch the screen to MediaPlayer to play an audio, it is able to be heard from handset (receiver). Thus, you can hear the far-end voice and your local music at the same time. Is it a normal behavior? Android seems not to have the mechanism to let Mediaplayer to remember its status (to keep music pause or mute?) in the phone call. Or this is a normal design for notification sounds, such as a call- waiting sound? Is it possible to have an secondary gain feature like windows mobile in the future?

View 5 Replies View RelatedIs there an Android equivalent to the iOS Core Audio / Audio File Stream Services? I need to be able to read audio bytes from a network and feed them to the audio system under my control, so I can do my own timeouts / reconnects / range requests / etc. without interrupting the audio playback (since the system audio thread would be playing audio already enqueued). It seems that MediaPlayer doesn't give me this level of control. Is there a lower-level framework that does, either in the SDK or NDK?

View 1 Replies View RelatedI'm writing an Android application that plays back voice mails using Media Player, which are just WAV files that have been sent to the device. When I play the file, it's played on the device's speaker, or else it plays through headphones if they're plugged in. What I want to do is play the file so that it sounds to the user as if it's at the same volume level as a normal phone call. Is there a way to route playback so that the file is played through the phone's ear piece instead of out of the speaker?

View 12 Replies View RelatedI currently have code that reads a recording in from the devices mic using the AudioRecord class and then playing it back out using the AudioTrack class.My problem is that when I play it out it plays vis the speaker phone.I want it to play out via the ear piece on the device.Here is my code:public class LoopProg extends Activity {
boolean isRecording; //currently not used
AudioManager am;
int count = 0;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
am = (AudioManager) getSystemService(Context.AUDIO_SERVICE);
am.setMicrophoneMute(true);
while(count <= 1000000){
Record record = new Record();
record.run();
count ++;
Log.d("COUNT", "Count is : " + count);
public class Record extends Thread
{ static final int bufferSize = 200000;
final short[] buffer = new short[bufferSize];
short[] readBuffer = new short[bufferSize];
public void run() {
isRecording = true;

AudioTrack atrack = new AudioTrack(AudioManager.STREAM_MUSIC,

AudioTrack.MODE_STREAM);
am.setRouting(AudioManager.MODE_NORMAL,1,

int ok = am.getRouting(AudioManager.ROUTE_EARPIECE);
Log.d("ROUTING", "getRouting = " + ok);
setVolumeControlStream(AudioManager.STREAM_VOICE_CALL);
//am.setSpeakerphoneOn(true);
Log.d("SPEAKERPHONE", "Is speakerphone on? : " + am.isSpeakerphoneOn());
am.setSpeakerphoneOn(false);
Log.d("SPEAKERPHONE", "Is speakerphone on? : " + am.isSpeakerphoneOn());
atrack.setPlaybackRate(11025);
byte[] buffer = new byte[buffersize];
arec.startRecording();
atrack.play();
while(isRecording) {
arec.read(buffer, 0, buffersize);
atrack.write(buffer, 0, buffer.length);
arec.stop();
atrack.stop();
isRecording = false;
As you can see if the code I have tried using the AudioManager class and its methods including the deprecated setRouting method and nothing works, the setSpeatPoneOn method seems to have no effect at all, neither does the routing method.Has anyone got any ideas on how to get it to play via the earpiece instead of the spaker phone?
I need to be able to stream audio from a custom file format on the C++ side of the Android system. I am working on porting a custom media player and need to be able to open a custom file and stream audio from it. This is important as I do not think porting the whole player to JAVA is feasible from a performance stand point and moving the audio buffers through the JNI interface I believe will be too slow to keep a decent frame rate. I can handle the video on the NDK side through OpenGL ES, but the Audio I have no idea how to make this happen.

View 4 Replies View RelatedI have multiple audio files in the assets directory of my application. When the user clicks a button I want to play those files in a certain order, one after the other. There shouldn't be any noticeable lag between the audio files. What is the best approach to achieve this? I am thinking of using MediaPlayer objects and OnCompletionListeners. But, that would mean I have to create a lot of OnCompletionListeners because I need to know every time which audio file is next. Am I missing something or is there a better approach?
