I'm getting an exception when trying to display a dialog box in Android. My AlertDialog is called from a FragmentActivity with the following code:

public static void displayShare(){
    // show share options
    CharSequence selections[] = new CharSequence[] {"Email", "SMS", "Tweet", "Phone Call", "Cancel"};
    final AlertDialog.Builder builder = new AlertDialog.Builder(CommonVariables.mContext);
    builder.setTitle("Share your location via...");
    builder.setItems(selections, new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            switch(which){
                case 0: // Email
                   callEmailMethod();
                    break;
                case 1: // SMS
                    callSMSMethod();
                    break;
                case 2: // Tweet
                    callTwitterMethod();
                    break;
                case 3: // Phone Call
                    callNumberMethod();
                    break;
                case 4:
                    dialog.cancel();
                    break;
            }
        }
    });
    builder.show();
}

The following error is received at the line: builder.show();

I have tried everything (except the correct solution, it seems). Any help is appreciated, thanks.

Note: CommonVariables.mContext is the context of the FragmentActivity and is not null: CommonVariables.mContext = FragmentAct.this;

Проблема заключалась в том, что мой проект был отсутствующий ресурс стиля для AlertDialog:

В styles.xml поставить это:

<style name="MyDialogTheme" parent="Theme.AppCompat.Light.Dialog.Alert" />

В своем коде, где вы создаете Диалог оповещения поставить это:

AlertDialog.Builder builder = new AlertDialog.Builder(getActivity(), R.style.MyDialogTheme);
