快速静默更新,低流量耗费,让APP活跃起来!

大家好,我是segmentfault的新人,给大家带来一个做了一个星期的SDK,可以实现将Android APP碎片化管理,自由更新,实时更新,低流量耗费的更新~~

Zag Whim Renewal

A system for quicker updating on Android

首先你要有一个Bmob移动后端云服务平台的账号

接下来,进入APP的数据浏览,在APP内建ZwrFile表,添加File类型的file列,添加String类型的name列

在Eclipse或者Android studio新建两个项目,称为Basic端和Expand端,分别导入对应的SDK

Basic端的Activity继承自ZwrActivity,实现InitListener接口,在onCreate方法内,先super,再Bmob.initialize(getApplicationContext(), appid),最后setZwrView("类名", this, true, false);

appid取自bmob后台,在“应用信息”里查看
“类名”为Expand端对应的类名,如“com.test.bmob.FirstView”
编译运行Basic端到手机

放一个layout.xml文件到ZwrFile表的file,name可以随便取,比如“main.xml”

Expand端删除所有代码,新建一个类,类名为上文所提到的(“com.test.bmob.FirstView”),继承自ZwrExpandView
将实现的抽象方法的LayoutName返回layout文件在ZwrFile对应的name,如上文的“main.xml”
在init函数内写初始化方法

编译Expand端,将编译出来的bin文件夹下的classes.dex上传到ZwrFile,name改为类名(“com.test.bmob.FirstView”)

启动Basic端,即可看到更新效果
以后需要更新逻辑代码,只需更新Activity对应的dex文件即可,需要更新布局,就更新对应的xml文件

部分代码示例:

Basic端:

import android.os.Bundle;  
import android.widget.Button;  
import cn.bmob.v3.Bmob;  

import com.zwr.ZwrActivity;  
import com.zwr.ZwrListener.InitListener;  

public class MainActivity extends ZwrActivity implements InitListener {  

    private Button bt;  

    private final String appid = "";  
    @Override  
    protected void onCreate(Bundle savedInstanceState) {  
        super.onCreate(savedInstanceState);  

        Bmob.initialize(getApplicationContext(),appid);  
        setZwrView("com.testzwr.ThirdView", this, true);  
    }  

    @Override  
    public void succeed() {  
        init();  
    }  

    @Override  
    public void fail(String why) {  
        toast(why);  
    }  

    @Override  
    public void lastView() {  
        init();  
    }  

    private final void init() {  
        bt = getView("zwrButton");  
        if (bt != null) {  
            bt.setText("hahhaa");  
        }  
    }  
}  

Extand端:

package com.testzwr;  

import android.app.Activity;  
import android.app.AlertDialog;  
import android.view.View;  
import android.view.View.OnClickListener;  
import android.widget.Button;  
import android.widget.EditText;  
import android.widget.TextView;  
import android.widget.Toast;  

import com.zwr.ZwrBasic.ZwrExpandView;  
import com.zwr.ZwrTool;  

public class ThirdView extends ZwrExpandView implements OnClickListener {  

    private Button bt;  
    private EditText et;  
    private TextView tv;  
    private Button bt_toast, bt_dialog, bt_change;  

    public ThirdView(Activity activity) {  
        super(activity);  
    }  

    @Override  
    public String LayoutName() {  
        return "third_layout.xml";  
    }  

    @Override  
    public void init() {  
        try {  
            et = getView("msg_et");  
            bt = getView("msg_send");  
            tv = getView("msg_show");  

            bt_toast = getView("toast");  
            bt_dialog = getView("dialog");  
            bt_change = getView("change");  
        } catch (NullPointerException e) {  
            return;  
        }  

        bt.setOnClickListener(new OnClickListener() {  

            @Override  
            public void onClick(View v) {  
                tv.append(et.getText().toString() + "\n");  
                et.setText("");  
            }  
        });  

        bt_toast.setOnClickListener(this);  
        bt_dialog.setOnClickListener(this);  
        bt_change.setOnClickListener(this);  

    }  

    private AlertDialog dialog;  

    @Override  
    public void onClick(View v) {  
        int i = v.getId();  
        if (i == bt_toast.getId()) {  
            Toast.makeText(getContext(), "hahaha", 1).show();  
        } else if (i == bt_dialog.getId()) {  
            if (dialog == null)  
                dialog = new AlertDialog.Builder(getContext())  
                        .setMessage("Hi~~").setTitle("恭喜你!").create();  
            dialog.show();  
        } else if (i == bt_change.getId()) {  
            bt_toast.setText("改变啦~丧失Toast能力,但能跳转到另一个Activity");  
            bt_dialog.setText("改变了还能弹窗");  
            bt_toast.setOnClickListener(new OnClickListener() {  

                @Override  
                public void onClick(View v) {  
                    try {  
                        ZwrTool.startActivity("com.test.sdkbuilder.SecondActivity");  
                    } catch (ClassNotFoundException e) {  
                        Toast.makeText(getContext(), "no this class", 1).show();  
                        e.printStackTrace();  
                    }  
                }  
            });  
            v.setVisibility(View.GONE);  
        }  
    }  

}
