Fragment dialog crashes app, any alternative fix?

trying to remove the top banner layer of an Android app, and I made this change in Android Manifest file,

android:theme="@android:style/Theme.NoTitleBar"

This crashed the app, and from another question in Stackoverflow itself, I changed

public class MainActivity extends AppCompatActivity

to

public class MainActivity extends FragmentActivity

And it worked, however, in the same Activity there is also a Dialog present, and whenever the dialog is clicked, it crashes the app again, So looking for a fix! any help will be appreciated.

Here is the logcat: 

05-16 21:25:27.796    1839-1839/zyia.alarm.zyia.zyia E/AndroidRuntime﹕ FATAL EXCEPTION: main

The code for the dialog Activity : 

import android.app.Dialog;
import android.content.DialogInterface;
import android.os.Bundle;
import android.support.v4.app.DialogFragment;
import android.support.v7.app.AlertDialog;
import android.view.LayoutInflater;

public class FireMissiles extends DialogFragment {
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    // Use the Builder class for convenient dialog construction
    AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());

    LayoutInflater inflater = getActivity().getLayoutInflater();

    builder.setView(inflater.inflate(R.layout.main_info, null))
            .setPositiveButton(R.string.fire, new  

   DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int id) {
                    // FIRE ZE MISSILES!
                }
            });

    // Create the AlertDialog object and return it
    return builder.create();
   }
}

You need to use a AppCompat theme.

Instead of using android:theme="@android:style/Theme.NoTitleBar"

Make a custom theme in res/styles

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
// Here you can customize the theme
</style>

Then in your manifest change the theme to that custom theme android:theme="@style/AppTheme"

If you would read the logcat you would see this line too:

java.lang.IllegalStateException: You need to use a Theme.AppCompat theme (or descendant) with this activity.

So the fix is self-explaining: in the android manifest add this instead of your theme:

android:theme="@android:style/Theme.AppCompat.NoTitleBar"
