How send a message to the emulator using DDMS in Android studio
i am trying to build a text messaging application in android, the code works, but the only thing wrong about it is that i cannot send messages to the emulator using DDMS. I have pasted my code below, just in case it is necessary, and i have the screen shot immediately after
package com.example.oghenekaroedoh.sms;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.telephony.SmsMessage;
import android.util.Log;
import android.widget.Toast;
/**

*/
public class SMSReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent)
{
//---get the SMS message passed in---
Bundle bundle = intent.getExtras();
SmsMessage[] msgs = null;
String str = "SMS from ";
if (bundle != null)
{
//---retrieve the SMS message received---
Object[] pdus = (Object[]) bundle.get("pdus");
msgs = new SmsMessage[pdus.length];
for (int i=0; i<msgs.length; i++){
msgs[i] = SmsMessage.createFromPdu((byte[])pdus[i]);
if (i==0) {
//---get the sender address/phone number---
str += msgs[i].getOriginatingAddress();
str += ": ";
}
//---get the message body---
str += msgs[i].getMessageBody().toString();
}
//---display the new SMS message---
Toast.makeText(context, str, Toast.LENGTH_SHORT).show();
Log.d("SMSReceiver", str);
}
}
}
Here is the code for the Activity, paste this code in another file..
package com.example.oghenekaroedoh.sms;
import android.app.Activity;
import android.app.PendingIntent;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.os.Bundle;
import android.telephony.SmsManager;
import android.view.View;
import android.widget.TextView;
import android.widget.Toast;

private void sendSMS(String phoneNumber, String message)
{
SmsManager sms = SmsManager.getDefault();
sms.sendTextMessage(phoneNumber, null, message, sentPI, deliveredPI);
}
}
here is how the DDMS output looks like:
The main problem here is that the radio buttons for the telephony actions are not clickeable. Someone please help me fix this
