如何在Android上发送电子邮件附件

Question

我已经成功创建了PDF文件，它存储在内部storage/app_name/files/xyz.PDF中，现在我只想在Gmail的附件中分享那个PDF......更新：在调试器中获取错误“源代码与字节码不匹配”

Here is the code:     
File filelocation = new 
File("/storage/emulated/0/Android/data/com.example.app_name/files/s.pdf");
Uri path = Uri.fromFile(filelocation); 
Intent emailIntent = new Intent(Intent.ACTION_SEND);
emailIntent .setType("vnd.android.cursor.dir/email");
String to[] = {"[e-mail]"};
emailIntent .putExtra(Intent.EXTRA_EMAIL, to);
emailIntent .putExtra(Intent.EXTRA_STREAM, path);
emailIntent .putExtra(Intent.EXTRA_SUBJECT, "Subject");
startActivity(Intent.createChooser(emailIntent , "Send email..."));

正在获取异常文件：///storage/emulated/0/storage/emulated/0/android/data/com.example.app_name/files/s.pdf通过clipdata.item.geturi（）在应用程序之外公开

使用下面的代码在电子邮件中发送文件。

String filename="xyz.pdf"; 
File filelocation = new File(Internal Storage/app_name/files/);
Uri path = Uri.fromFile(filelocation); 
Intent emailIntent = new Intent(Intent.ACTION_SEND);
// set the type to 'email'
emailIntent .setType("vnd.android.cursor.dir/email");
String to[] = {"[e-mail]"};
emailIntent .putExtra(Intent.EXTRA_EMAIL, to);
// the attachment
emailIntent .putExtra(Intent.EXTRA_STREAM, path);
// the mail subject
emailIntent .putExtra(Intent.EXTRA_SUBJECT, "Subject");
startActivity(Intent.createChooser(emailIntent , "Send email..."));
