Creating Android Project for Simple Application

This section provides tutorial example on how to create an Android project for a simple Android application using command line tools.

To build any Android applications, we need to create an Android project folder structure first.

Here is what I did to create a simple project called AboutAndroid in a command window:

C:\>cd \herong
C:\herong>JAVA_HOME=\Program Files\Java\jdk1.8.0_45\

C:\herong>\local\android-sdk-windows\tools\android create project \ 
   --package com.herongyang --activity AboutAndroid --target 2 \
   --path .\AboutAndroid
Created project directory: C:\herong\AboutAndroid
..
Added file C:\herong\AboutAndroid\build.xml

C:\herong>cd .\AboutAndroid
C:\herong\AboutAndroid>edit .\src\com\herongyang\AboutAndroid.java
/* AboutAndroid.java
 * Version 1.0 - Displaying text message
 * Copyright (c) 2015, HerongYang.com, All Rights Reserved.
 */
package com.herongyang;

import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;
public class AboutAndroid extends Activity {
   @Override
   public void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      String msg = "";
      
      msg += "About Android\n";
      msg += "-------------\n";

      TextView tv = new TextView(this);
      tv.setText(msg);
      setContentView(tv);
   }
}

C:\herong\AboutAndroid>edit .\res\layout\main.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
<TextView
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    />
</LinearLayout>
