Private Boolean ispreparedforsending () {
if (isrecipientseditorvisible ())
{
String Recipienttext = Mrecipientseditor.gettext () ==null? ": Mrecipientseditor.gettext (). toString ();
Return msimcount>0 &&! Textutils.isempty (Recipienttext);
}else{
Return msimcount>0;
}
}
2, add in the Smssinglerecipientsender.java
Import Android.text.TextUtils;
And in the function public boolean sendMessage (long token, int simid), "int messagecount = Messages.size ();" Before joining
if (Textutils.isempty (Mmessagetext)) {
Messages.add ("");
}

Isvalidparameters (String destinationaddress, string parts, Pendingintent sentintent) method,
Remove the part of this method that parts is empty.
if (Parts==null | | parts.size () <1) {

}
In addition, if the screen in the case of receiving information, this time the information directly show, I hope in the dialogmodeactivity this interface can also support the reply to empty text messages, in addition to the above changes, but also need to modify the following code:
This document will be Dialogmodeactivity.java to make the following changes:
1. Modify the private void Updatesendbuttonstate () {Approximately 2242 lines, and modify the IF (len>0) to if (len>=0), as follows:
private void Updatesendbuttonstate () {
Boolean enable = false;
int len = Mreplyeditor.gettext (). toString (). Length ();
MMSLOG.D (TAG, "Dialogmodeactivity.updatesendbuttonstate (): len =" + len);
if (Msendbutton! = null) {
if (len >= 0) {//Modify for send blank SMS
MMSLOG.D (TAG, "updatesendbuttonstate (): Msimcount =" + Msimcount);
2. Modification:
Onpremessagesent () {
MMSLOG.D (TAG, "dialogmodeactivity.onpremessagesent");
if (muris!= null &&!muris.isempty ()) {
Runonuithread (mresetmessagerunnable);
}
3. Runnable mresetmessagerunnable = new Runnable () {
public void Run () {
if (muris!= null &&!muris.isempty ()) {
MMSLOG.D (TAG, "Mresetmessagerunnable.run");
Resetmessage ();
}
}
};
