Android Question AudioStreamer object

[hookshy]

I have installed the library from this link
Audio library v1.5
http://www.b4x.com/android/forum/threads/audio-library-v1-5-new-audiostreamer-object.30550/#content

The example seem to work fine but when I put it in to my app here what came out .
https://www.dropbox.com/s/bz4idrq8qf7xasn/1.wav
If you could give me a hint about what might probably go wrong I could apreciate... I will come back as soon as I find an answer myself .
I know this lib is on beta testing so maybe my case would be small help as tester !
Thank you

Found problem by not copying the right initialise statement and the sample rate got to the crapy effect from the audio file above !
Device I have tested the library motorola defy+ android 2.3.2

streamer.Initialize("streamer", mSampleRate, mMono, mBitRate, streamer.VOLUME_MUSIC)
'streamer.Initialize("streamer", 44100, True, 16, streamer.VOLUME_MUSIC) 'this statement was from previous example :rolleyes:

Sometime we make the code do strange things when coding !!!
thank you for this library

 

[hookshy]

while playing with example from library and the test I made I have the following errors .
On example :
error on java line 290 illegalStateException:stop() called on an uninitilised Audiorecord
ON my implementation:
I can press record but the file I can not play the file
error java.io.IOException : Prepared failed: status=0x1

 

[hookshy]

Fixed problem ... off .. I have wrong handled the button for recording, stop and play .
The recorder was started but and never stopped !

NEW PROBLEM on device:
Vodafon smart II (No carrier , no sim inserted)
Android 2.3.7
320 x 480 px, 3.2 '' (180 ppi )

on line: streamer.Initialize("streamer", mSampleRate, mMono, mBitRate, streamer.VOLUME_MUSIC)
Error: NegativeARraySizeException !!
Simple try catch end try over streamer intialisation will start the app but surely the recorder function won't work.

This device has not SIM inserted are there related in some way ?

 

[Erel]

The latest version of Audio library should raise the Error event in this case.

This error means that the device doesn't support these parameters.

 

[hookshy]

This error I got on LGOptimus l5 while the app works great on Motorola Defy +
Fatal signal 6 (SIGABRT) at 0x00000180 (code=0)
Error occured on activity create ! And the message box that give you the option to wait for the app is often showing when creating streamer object .

Regarding the parametrers of the streamer it is possible that some configuration to crack on some phones ?
Does each device have it one hardware configuration that support more of less more parameter and how can you tell this from the first install of the app?
How important is the channel in the streamer initialise and how could you now what channel works ?

 

[hookshy]

Because I am handeling both the library example and my test record example i have an error each time when pressing play button to record . (called on an uninitilised Audiorecord)
I have restarted the phone in order to catch the problem and after restart the first app that runs is recording just fine .
That means that a release must be done before leaving the app is this correct ?
I have used this code found here to release the job in activity pause

  Dim r As Reflector
  r.Target = streamer
  r.Target = r.GetField("audioRecord")
  r.RunMethod("release")

I hope I am not wrong actually I used the release option only when userclosed option in activity pause as for example a scaner or voice recognition will not recreate the activity but only pause and resume .
Please correct me when I am writing BS.

Strange thing is that the app that handles the same hardware resource wrong will cause eventually the crash of the other one .. but the users does not feel that and may tell that your app actually sucks and that is not good .. the problem was same place else!
This might be the case of a lot of other hardware resources on android device !

 

[Erel]

Which configuration are you using? You can catch the error and try a different set of configuration parameters.

About the channel, Android maintains several volume channels. This setting affect the playback volume level.

Your "release" code looks correct.

 

[hookshy]

I did not changed nothing from the lib example
As soon as I will catch something I will post error . Thank you !
I have inserted also the lastexception routine !

Private streamer As AudioStreamer
    Private buffers As List
    Private timer1 As Timer
    Private recordingStart As Long
  
  
    Private output As OutputStream
    Private recording As Boolean
    Private mBitRate As Int = 16
    Private mSampleRate As Int = 22050
    Private mMono As Boolean = True
    Private mFileName As String = "ac.wav"
    Private mp As MediaPlayer

        buffers.Initialize
        streamer.Initialize("streamer", mSampleRate, mMono, mBitRate, streamer.VOLUME_MUSIC)

I had another crash on Motorola this time, this is what I see in my logs ! I do not know if this helps but I do report any problems I met !
I have restarted app and recorder works fine !

Can you post the stack trace when that happens?

 

[hookshy]

Can you post the stack trace when that happens?

I am afraid I do not now how to do that !

Another thing I see :
By pressing home button while recording I see the following statement in log . by resuming the recording is resuming again !
sending message to waiting queue (streamer_recordbuffer)
Ignoring event (too many queued events: streamer_recordbuffer)

 

[Erel]

This happens because the activity is paused. You should use a service if you want to record while the app is in the background.

 

[hookshy]

Ok .. I understand .. the purpose is not to record in background but to record simple message in order to share it via what app ... so it is not a problem .
