In this document, I will guide you step by step, therefore, you need to read and practice up to down. We will write each version of the game from 1 to the final version.

2- Create a Game Project

Note that you're creating a 2D game on Android, so the interface of the game must be drawn by you, so you do not need aactivity_main.xml file.

OK, your Project was created.

3- Preparing Images and sounds

You need a few images

explosion.png

The Audio file of the explosion.

explosion.wav

Background sound:

background.mp3

Copy these images to the drawable folder of project. Create raw folder, and copy explosion.wav & background.mp3 to this folder.

4- Setting fullscreen (Version:1)

With games, you need to set the background image and an important thing is that you need to set FullScreen mode.

Your MainActivity class must extends from the Activity class .

MainActivity.java (Version: 1)

package org.o7planning.androidgame2d;

import android.app.Activity;

import android.os.Bundle;

import android.view.Window;

import android.view.WindowManager;

public class MainActivity extends Activity {

    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        // Set fullscreen

        this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,

                WindowManager.LayoutParams.FLAG_FULLSCREEN);

        // Set No Title

        this.requestWindowFeature(Window.FEATURE_NO_TITLE);

    }

}
