如何用SD卡中的文件路径发送音频文件？

有无论如何，我可以发送电子邮件，当我从SD卡按OUTPUT_FILE路径保存按钮。（我没有实现保存按钮）我是否应该将字符串更改为Uri而不是发送电子邮件？我不知道如何实现保存按钮，使其发送附带音频文件的电子邮件。有什么建议么？提前致谢！如何用SD卡中的文件路径发送音频文件？

Intent i = new Intent(Intent.ACTION_SEND); 
    i.setType("audio/rfc822"); 
    i.putExtra(Intent.EXTRA_EMAIL, new String[] {"[email protected]"}); 
    i.putExtra(Intent.EXTRA_SUBJECT, "MySubject"); 
    i.putExtra(Intent.EXTRA_STREAM, Uri.parse(Environment.getExternalStorageDirectory().getAbsolutePath() + File.separator + "audiorecorder.3gpp"); 
    startActivity(i);

希望这有助于！

我是否应该将sdcard中的文件路径（OUTPUT_FILE = Environment.getExternalStorageDirectory（）+“/ audiorecorder.3gpp”;）转换为Uri以使用您的代码？ –

你应该。那只是例如！ – ThePCWizard
