[android-developers] Create a wav file and stock this into a data storage with Content Providers

[Dany BREARD]

How can I take:  "Create a wav file and stock this into a data storage
with Content Providers"

I try to use the same thing like the following exemple:

http://developer.android.com/intl/fr/guide/topics/providers/content-providers.html

with a Bitmap:

import android.provider.MediaStore.Images.Media;
import android.content.ContentValues;
import java.io.OutputStream;

// Save the name and description of an image in a ContentValues map.
ContentValues values = new ContentValues(3);
values.put(Media.DISPLAY_NAME, "road_trip_1");
values.put(Media.DESCRIPTION, "Day 1, trip to Los Angeles");
values.put(Media.MIME_TYPE, "image/jpeg");

// Add a new record without the bitmap, but with the values just set.
// insert() returns the URI of the new record.
Uri uri = getContentResolver().insert(Media.EXTERNAL_CONTENT_URI,
values);

// Now get a handle to the file for that record, and save the data
into it.
// Here, sourceBitmap is a Bitmap object representing the file to save
to the database.
try {
    OutputStream outStream = getContentResolver().openOutputStream
(uri);
    sourceBitmap.compress(Bitmap.CompressFormat.JPEG, 50, outStream);
    outStream.close();
} catch (Exception e) {
    Log.e(TAG, "exception while writing image", e);


So I think is too similar but I'm really lose !!

Firstly I don't find how to create my File with my byte[].

I try to make that:

    byte[] decoded = Base64.decode( tabMsg[0].getMsgBase64() );

            ContentValues values = new ContentValues();
            values.put(Media.DISPLAY_NAME, "Voicemail1");
            values.put(Media.MIME_TYPE, "Audio/wav");

            Uri uri = getContentResolver().insert(Media.EXTERNAL_CONTENT_URI,
values);

            File m_wav = new File(uri.getEncodedPath(), "voicemail1.wav");

            try
            {
                OutputStream outStream = getContentResolver().openOutputStream
(uri);
                outStream.write(decoded);
                outStream.close();
            }
            catch (Exception e)
            {
                Log.e(TAG, "Exception while writing audio", e);
            }


Could you light me, please ??
What are you thinking about my little code and how can I
continuous ???

It's very hard to use the better arguments or parametres with:
values.put(...) and with : getContentResolver().insert(..)

Maybe I have to create my own Content Providers but I think is too
compicated !
