android - 通过 WhatsApp 共享原始资源

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"));

上面的代码在 Gmail 上运行良好，而 Whatsapp 会给出一个 toast 消息，例如“共享文件失败，请重试”

也许我和这个人有同样的问题:Intent.ACTION_SEND Whatsapp

但是我怎样才能把我的资源暂时复制到sd卡上，然后共享呢？

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;
