I am using 3 external jar files.
您应该使用URI来引用资产目录中的PDF文件myfile.pdf，如下所示：
Uri uri=Uri.parse("file:///android_asset/myfile.pdf");
i've done for send any file from SD card with mail attachment..
Intent sendEmail= new Intent(Intent.ACTION_SEND);
sendEmail.setType("rar/image");
sendEmail.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(new
File("/mnt/sdcard/download/abc.rar")));
startActivity(Intent.createChooser(sendEmail, "Email:"));
