smsmanager不在alertdialog中工作

Question

继承我正在做的事情的代码。我点击了一个提交按钮，然后是一个警告框，其中有是/否显示确认，当你点击是时它应该发送一个文本并保存一个pdf版本。一切都有效，除了文字，并没有说它也没有发送。

    submit = (Button) findViewById(R.id.button1);
    submit.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {

            AlertDialog.Builder alertDialog = new AlertDialog.Builder(shortinsp.this);

            // Setting Dialog Title
            alertDialog.setTitle("Submit Inspection...");

            // Setting Dialog Message
            alertDialog.setMessage("Are you sure you are Ready?");

            // Setting Positive "Yes" Button
            alertDialog.setPositiveButton("YES", new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog,int which) {
                    tvstore = (TextView) findViewById(R.id.textView19);
                    //     result = (TextView) findViewById(R.id.score);
                    String ph = (Config.NUMBER);
                    String msg = (tvstore +" short " + result);
                    try {
                        SmsManager.getDefault().sendTextMessage(ph, null, msg, null, null);
                    } catch (Exception e){
                           Toast.makeText(getApplicationContext(), "Unable to send text", Toast.LENGTH_SHORT).show();

                    }
                    printPDF();

                    // Write your code here to invoke YES event
                    //   Toast.makeText(getApplicationContext(), "You clicked on YES", Toast.LENGTH_SHORT).show();
                }


            });

            // Setting Negative "NO" Button
            alertDialog.setNegativeButton("NO", new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int which) {
                    // Write your code here to invoke NO event
                    //    Toast.makeText(getApplicationContext(), "You clicked on NO", Toast.LENGTH_SHORT).show();
                    dialog.cancel();
                }
            });

            // Showing Alert Message
            alertDialog.show();
        }
    });
}

没有崩溃，printPDF按计划工作。但由于某种原因，文本永远不会发生。我有权限。我做错了什么？
