Android AlertDialog exception "Resources$NotFoundException"

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;

Answer

The problem was that my project was missing the style resource for the AlertDialog:

In styles.xml put this:

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

In your code where you create the Alert Dialog put this:

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

Thanks for @Fraranc in this post for the answer : Resources$NotFoundException: Resource ID #0x0 in AlertDialog
