First check file is created or not. If it is created, try using this code:
public static void sendAsMail(File file, Context econtext) {
try {
final Intent emailIntent = new Intent(
android.content.Intent.ACTION_SEND);
emailIntent.setType("text/*");
emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL,
new String[] { "" });
emailIntent.putExtra(android.content.Intent.EXTRA_CC,
new String[] {});
emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT,
"FROM Sample");
emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, "HI");
emailIntent.putExtra(android.content.Intent.EXTRA_STREAM,
Uri.parse(file.toURI().toString()));
mContext.startActivity(emailIntent);
} catch (Exception e) {
}
}
If it Doesn't works then comment.
