Q:

App crashed when AlertDialog is about

I have a list view, the contain is populated from a database. And I put a button on each row, when it's clicked it shows an AlertDialog box.
I have no errors on my project, but the app crashes everytime I click the button for the AlertDialog box.
Here's my code:
donate_now.setOnClickListener(new OnClickListener() {
 public void onClick(View view) {
   AlertDialog.Builder alertbox = new AlertDialog.Builder(ProjectsList.this);
   alertbox.setTitle("SMS");
   alertbox.setMessage (Html.fromHtml(("Ihr SMS wird vorbereitet. Bitte 
                        bestätigen Sie mit 'Ok' und senden Sie danach die SMS ab! 
                        <p><small>Sie helfen dem Projekt mit " +mPriceIndex + ". 
                        Betrag je SMS zzgl. Transport. Der Betrag abzüglich 17 Cent 
                        geht direkt an die Partner-Organisation.")));                                                   
 alertbox.setNeutralButton("Ok", new DialogInterface.OnClickListener() {
 public void onClick(DialogInterface arg0, int arg1) {
    Intent sendIntent = new Intent(Intent.ACTION_VIEW);
    sendIntent.putExtra("address", mShortcodeIndex); 
    sendIntent.putExtra("sms_body", mKeywordIndex); 
    sendIntent.setType("vnd.android-dir/mms-sms");
    startActivity(sendIntent);
   }   
  });
  alertbox.show();

Can anybody help me analyze where do I go wrong?
Here's the debug:

A:

You need to give the proper context to the alertDialog which must be the current activity context.So you need to declare a context for activity.
//At the beginning of class where you declare the Listview
ListView lv;
Context ctx = this;

And in your method.
donate_now.setOnClickListener(new OnClickListener() {
             public void onClick(View view) {

                 AlertDialog.Builder alertbox = new AlertDialog.Builder(ctx);
                                        alertbox.setTitle("SMS");
                                        alertbox.setMessage (Html.fromHtml(("Ihr SMS wird vorbereitet. Bitte bestätigen Sie mit 'Ok' und senden Sie danach die SMS ab! <p><small>Sie helfen dem Projekt mit " +mPriceIndex + ". Betrag je SMS zzgl. Transport. Der Betrag abzüglich 17 Cent geht direkt an die Partner-Organisation.")));

                                        alertbox.setNeutralButton("Ok", new DialogInterface.OnClickListener() {

                                            public void onClick(DialogInterface arg0, int arg1) {
                                                Intent sendIntent = new Intent(Intent.ACTION_VIEW);
                                                sendIntent.putExtra("address", mShortcodeIndex); 
                                                sendIntent.putExtra("sms_body", mKeywordIndex); 
                                                sendIntent.setType("vnd.android-dir/mms-sms");
