1.使用Android Studio作为主要IDE进行学习开发。

    学习网站:http://www.runoob.com/w3cnote/android-tutorial-intro.html

    之后只会做必要的笔记记录,一是方便自己查找笔记,二也是希望对后来者有些许帮助!

2.第一个程序

AS界面:


package com.example.sassassaisn.firstapp;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }
}


    

真机运行:

3.反编译:

    对于coder来说图片UI什么的最烦人了,哈哈~

    当你的资源不是充足的时候,就可以反编译别人的APK,方法:将apk后缀改为zip即可,emmm~
