Share raw resource via WhatsApp

Question

Intent share = new Intent(Intent.ACTION_SEND);
share.putExtra(Intent.EXTRA_STREAM, Uri.parse("android.resource://" + ContextID.getPackageName() + "/" + ResourceID));
share.setType("audio/*");
ContextID.startActivity(Intent.createChooser(share, "Condividi il suono"));

The above code works fine with Gmail, while Whatsapp gives a toast message like "Share a file failed, please try it again"

Maybe i've the same problem of this guy: Intent.ACTION_SEND Whatsapp

But how can i temporarily copy my resources on sd card and then share them?

Answer 1

File dest = Environment.getExternalStorageDirectory();
InputStream in = ContextID.getResources().openRawResource(ResourceID);              

try 
{
    OutputStream out = new FileOutputStream(new File(dest, "lastshared.mp3"));  
    byte[] buf = new byte[1024];
    int len;
    while ( (len = in.read(buf, 0, buf.length)) != -1)
    {
        out.write(buf, 0, len);
    }
    in.close();
    out.close();
}
catch (Exception e) {}              

Intent share = new Intent(Intent.ACTION_SEND);
share.putExtra(Intent.EXTRA_STREAM, Uri.parse(Environment.getExternalStorageDirectory().toString() + "/lastshared.mp3"));
share.setType("audio/*");
ContextID.startActivity(Intent.createChooser(share, "Condividi il suono \"" + TheButton.getText() + "\""));
return true;

manifest:

<manifest ...>
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"></uses-permission>
    ...
</manifest>

Answer 2

please change this line from your code and you will be able to share write ("audio/mp3") as bellow instead ("audio/*")

share.setType("audio/mp3");

this is because share type for whatsapp doesn't support ("audio/*") or ("*/*")
