the application has stopped unexpectedly please try again in android
I am new in android platform. I got a problem. When I run my application, I have error "Application has stopped unexpectedly"
I try some solution, but I don't get it and it's still not working.
Can somebody help me?
My code
package com.example.popup;
import android.app.Activity;
import android.app.AlertDialog;
import android.content.DialogInterface;
import android.content.Intent;
import android.os.Bundle;
public class PopSMSActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// no need for XML layouts right now
// we will use a dialog instead
//setContentView(R.layout.main);
// retrieve Serializable sms message object
// by the key "msg" used to pass it
Intent in = this.getIntent();
PopMessage msg = (PopMessage) in.getSerializableExtra("msg");
// Case where we launch the app to test the UI
// i.e. no incoming SMS
if(msg == null){
msg = new PopMessage();
msg.setSender("0123456789");
msg.setTimestamp( System.currentTimeMillis() );
msg.setBody(" this is a test SMS message!");
}
showDialog(msg);
}
private void showDialog(PopMessage msg){
final String sender = msg.getSender();
final String body = msg.getBody();
final String display = sender + "\n"
+ msg.getShortDate( msg.getTimestamp() )+ "\n"
+ body + "\n";
// Display in Alert Dialog
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setMessage(display)
.setCancelable(false)
.setPositiveButton("Reply", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
// reply by calling SMS program
// smsReply(sender, body);
}
})
.setNegativeButton("Close", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
// go back to the phone home screen
// goHome();
}
});
AlertDialog alert = builder.create();
alert.show();
}
}
PopUpAct
package com.example.popup;
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.telephony.SmsMessage;
public class PopUpAct extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
Bundle bundle = intent.getExtras();
//get the sms received
Object[] pdus = (Object[]) bundle.get("pdus");
SmsMessage[] msgs = new SmsMessage[pdus.length];
String smsSender = "";
String smsBody = "";
long timestamp = 0L;
for (int i=0; imsgs[i] = SmsMessage.createFromPdu((byte[])pdus[i]);
smsSender += msgs[i].getOriginatingAddress();
smsBody += msgs[i].getMessageBody().toString();
timestamp += msgs[i].getTimestampMillis();
}
intent.putExtra("sender",smsSender);
intent.putExtra("body", smsBody);
intent.putExtra("timestamp",timestamp);
PopMessage pop_msg = new PopMessage();
intent.setClass(context, PopSMSActivity.class);
intent.setFlags(intent.FLAG_ACTIVITY_NEW_TASK);
intent.putExtra("msg", pop_msg);
context.startActivity(intent);
}
}
PopMessage
package com.example.popup;
import java.io.Serializable;

import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.GregorianCalendar;
public class PopMessage implements Serializable{
