[android-developers] MediaPlayer onCompletion is not being called accurately
In my app i have created an audio player (only WAV files) using
MediaPlayerhttp://developer.android.com/reference/android/media/MediaPlayer.htmlAPI.
But the player doesn't give callback to onCompletion Listener
everytime. Sometimes it gives callback but not everytime. I am doing some
audio processing on wav file , like insertion and overwriting.
Is it because any missing in audio header? Why it doesn't give callback
when the playback is completed?
here is the code:
mMediaPlayer.setOnCompletionListener(new OnCompletionListener() {
@Override
public void onCompletion(MediaPlayer mp) {
// realease media player
// update player ui
}
});

Here is the code how i create and update wav header:
public void createWAVHeader(int sRate,int byteRate,int nChannels,int
BitsPerSample,long length){
byte[] header = new byte[44];
header[0] = 'R'; // RIFF/WAVE header
header[1] = 'I';
header[2] = 'F';
header[3] = 'F';
header[4] = (byte) ((length+36) 0xff);
header[5] = (byte) (((length+36) 8) 0xff);
header[6] = (byte) (((length+36) 16) 0xff);
header[7] = (byte) (((length+36) 24) 0xff);
header[8] = 'W';
header[9] = 'A';
header[10] = 'V';
header[11] = 'E';
header[12] = 'f'; // 'fmt ' chunk
header[13] = 'm';
header[14] = 't';
header[15] = ' ';
header[16] = 16; // 4 bytes: size of 'fmt ' chunk
header[17] = 0;
header[18] = 0;
header[19] = 0;
header[20] = 1; // format = 1
header[21] = 0;
header[22] = (byte) nChannels;
header[23] = 0;
header[24] = (byte) (sRate 0xff);
header[25] = (byte) ((sRate 8) 0xff);
header[26] = (byte) ((sRate 16) 0xff);
header[27] = (byte) ((sRate 24) 0xff);
header[28] = (byte) (byteRate 0xff);
header[29] = (byte) ((byteRate 8) 0xff);
header[30] = (byte) ((byteRate 16) 0xff);
header[31] = (byte) ((byteRate 24) 0xff);
header[32] = (byte) (2 * 16 / 8); // block align
header[33] = 0;
header[34] = (byte) BitsPerSample; // bits per sample
header[35] = 0;
header[36] = 'd';
header[37] = 'a';
header[38] = 't';
header[39] = 'a';
header[40] = (byte) (length 0xff);
header[41] = (byte) ((length 8) 0xff);
header[42] = (byte) ((length 16) 0xff);
header[43] = (byte) ((length 24) 0xff);
try {
rafOut.write(header, 0, 44);
} catch (IOException e) {
e.printStackTrace();
}}
Here is the code for updating the header when new audio data is been
recorded
public void updateHeader(String inFile){
long totalAudioLen = 0;
long totalDataLen =0; // totalAudioLen + 36
FileInputStream in = null;
try
{
in = new FileInputStream(inFile);
totalAudioLen = (in.getChannel().size()-44);
totalDataLen = (totalAudioLen) + 36;
RandomAccessFile invFile = new RandomAccessFile(inFile, rw);
invFile.seek(4);
invFile.write((byte) (totalDataLen 0xff));
invFile.write((byte) ((totalDataLen 8) 0xff));
invFile.write((byte) ((totalDataLen 16) 0xff));
invFile.write((byte) ((totalDataLen 24) 0xff));
invFile.seek(40);
invFile.write((byte) (totalAudioLen 0xff));
invFile.write((byte) ((totalAudioLen 8) 0xff));
invFile.write((byte) ((totalAudioLen 16) 0xff));
invFile.write((byte) ((totalAudioLen 24) 0xff));
invFile.close();
}catch (Exception e) {
// TODO: handle exception

[android-developers] How to create soap request in ksoap2 for a wcf webservice method with complex types?
I have successfully accessed web services using ksoap2 but i am stuck with
calling a web service method with data contracts.
The webservice request in SoapUI is shown as :
soapenv:Envelope xmlns:soapenv=http://schemas.xmlsoap.org/soap/envelope/;
xmlns:tem=http://tempuri.org/;
xmlns:pat=http://schemas.datacontract.org/2004/07/Patient_Service.App_Code.Common;soapenv:Header/soapenv:Body
tem:PatientLookups
tem:oBenefitsandEligibilityEntity
pat:ID?/pat:ID
pat:Name?/pat:Name
pat:Age?/pat:Age
pat:Address?/pat:Address
/tem:oBenefitsandEligibilityEntity
/tem:PatientLookups
/soapenv:Body
The arguments ID,Name,Age and Address have different namespaces
Here is the code i used to create the request:
request=new SoapObject(NAMESPACE,PatientLookups);SoapObject sub_element=new
SoapObject(NAMESPACE, oBenefitsandEligibilityEntity);
for(Map.EntryString,String entry: properties.entrySet())
{
PropertyInfo pi=new PropertyInfo();
pi.setNamespace(entityNameSpace);
pi.setName(entry.getKey());
pi.setValue(entry.getValue());
sub_element.addProperty(pi);
}
request.addSoapObject(sub_element);
but i get this exception in logcat:
SoapFault - faultcode: 'a:DeserializationFailed' faultstring: 'The formatter

no problem when changing tabs, the listview consists of details of recorded audio files, so when any list item is clicked, it should start new Activity player to play the audio file, but it goes wrong when an item is clicked. :( :( :( -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Starting an activity from Fragments.
instead of creating the intent and starting the activity, just do nothing.
-- didnt crash.
If that doesn't crash, construct the intent as before (but don't start the
activity yet). If that is OK, pop up a message with Toast after creating the
intent (so we are hopefully taking the focus away from the tab layout
briefly).
yes, pop up message was shown successfully.
If all of that is OK, try creating a dummy activity of your own with a
button, and have the intent use *that* class (and start the activity) -
didnt work, application crashed.

[android-developers] Re: Starting an activity from Fragments.
Thank you Jason Teagle, The error was in player activity, the player class needed a native library and that library was missing. You were so kind to listen me. Thankyou so much. On May 9, 4:46 pm, Jason Teagle teagle.ja...@gmail.com wrote: Sorry, It worked! I forgot to add the activity in manifest. (Don't worry, I just learned something about activities there as well!) OK, so the dummy activity worked, and that also means that taking focus away from the tab arrangement *shouldn't* be the problem - since that would have happened for your dummy activity. Is the 'player' activity one of your own classes? I'm afraid the fault points to that now. I recommend you start isolating parts of that (in its onCreate() ) and try to narrow down the cause like we did here. -- You received this message because you are subscribed to the Google Groups Android Developers group.

The steps i followed are:
1. Writing the data from file1 upto pause position:
