Fixed version (ground truth):
@Override public void onReceive(Context context,Intent intent){
  Bundle bundle=intent.getExtras();
  SmsMessage[] msgs=null;
  String msg="String_Node_Str";
  String smsSenderNum="String_Node_Str";
  if (bundle != null) {
    Object[] pdus=(Object[])bundle.get("String_Node_Str");
    msgs=new SmsMessage[pdus.length];
    for (int i=0; i < msgs.length; i++) {
      msgs[i]=SmsMessage.createFromPdu((byte[])pdus[i]);
      msg+=msgs[i].getMessageBody().toString();
      smsSenderNum=msgs[i].getOriginatingAddress();
    }
    if (smsSenderNum.contains("String_Node_Str"))     smsSenderNum=smsSenderNum.substring(smsSenderNum.length() - 10,smsSenderNum.length());
    Intent newIntent=new Intent(context,CustomDialogActivity.class);
    newIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    newIntent.putExtra("String_Node_Str",smsSenderNum.toString());
    newIntent.putExtra("String_Node_Str",msg);
    MessageParser mp=new MessageParser(msg);
    Log.v("String_Node_Str",smsSenderNum);
    Toast.makeText(context,smsSenderNum,Toast.LENGTH_SHORT).show();
    if (mp.isAppMessage()) {
      if (!mp.isAcknowledgement()) {
        MySharedData sd=(MySharedData)context.getApplicationContext();
        CustomDialog flashScreen=sd.getFlashScreen();
        if (flashScreen == null)         context.startActivity(newIntent);
 else {
          flashScreen.getMsgToBeAck().add(msg);
          flashScreen.setCommanderNumber(smsSenderNum.toString());
          flashScreen.updateTextView();
        }
      }
 else {
        DBAdapter dba=new DBAdapter(context);
        dba.open();
