关于安卓自动升级的一些思路

通过接口，返回新版本的版本号以及新版本下载地址，通过Downloadmangeri下载更新。

1.UpdateActivity（实现下载功能的主代码）

package com.tolly.parking;import android.app.DownloadManager;import android.app.ProgressDialog;import android.content.*;import android.database.Cursor;import android.net.Uri;import android.os.Bundle;import android.os.Environment;import android.os.Handler;import android.os.Message;import android.support.annotation.Nullable;import android.support.v4.content.LocalBroadcastManager;import android.support.v7.app.AlertDialog;import android.support.v7.app.AppCompatActivity;import android.text.TextUtils;import android.util.Log;import android.widget.Toast;import com.tolly.parking.entity.UpdateInfo;import com.tolly.parking.enumeration.FunctionListEnum;import com.tolly.parking.serviceImpl.UpdateServicelmpl.UpdateServicelmpl;import com.tolly.parking.util.DeviceInfoUtil;import com.tolly.parking.vo.UpdateVO;import org.codehaus.jackson.map.ObjectMapper;import java.io.File;import java.io.IOException;import java.util.concurrent.Callable;import static com.tolly.parking.enumeration.CommandEnum.DOWN_ERROR;import static com.tolly.parking.enumeration.CommandEnum.GET_UNDATAINFO_ERROR;import static com.tolly.parking.enumeration.CommandEnum.UPDATA_CLIENT;import static com.tolly.parking.util.JsonTransitionObjectUtil.objectMapper;/** * Created by zyy on 2017/7/19. */public class UpdateActivity extends AppCompatActivity {    private String versionName;    private int versionCode;    MyReceiver receiver = new MyReceiver();    public static final String BROADCAST_ACTION =            "com.example.android.threadsample.BROADCAST";    public static final String EXTENDED_DATA_STATUS =            "com.example.android.threadsample.STATUS";    private LocalBroadcastManager mLocalBroadcastManager;    //服务器中APK下载地址    private String updateurl;    private Context context;    //自动更新的实现类    private UpdateServicelmpl UpdateService;    public final Handler handler = new Handler() {        @Override        public void handleMessage(Message msg) {            super.handleMessage(msg);            Bundle bundle = msg.getData();            switch (msg.arg1) {                case UPDATA_CLIENT:                    //处理服务器返回的结果                    handleUpdateClientResult(bundle);                    break;//                case GET_UNDATAINFO_ERROR://                    //服务器超时//                    Toast.makeText(getApplicationContext(), "获取服务器更新信息失败", Toast.LENGTH_SHORT).show();//                    LoginMain();//                    break;//                case  DOWN_ERROR://                    //下载apk失败//                    Toast.makeText(getApplicationContext(), "下载新版本失败",  Toast.LENGTH_SHORT).show();//                    LoginMain();//                    break;            }        }    };    @Override    protected void onCreate(@Nullable Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        //获得APP版本名称和版本号        versionName = DeviceInfoUtil.getAppVersionName(getApplicationContext());        versionCode = DeviceInfoUtil.getAppVersionCode(getApplicationContext());//        Log.i("测试：", "versionName:"+versionName+",versionCode:"+versionCode);        //更新接口        UpdateService = new UpdateServicelmpl(handler);        UpdateVO updatevo = new UpdateVO();        try {            UpdateService.UpdateClient(updatevo);        } catch (Exception e) {            e.printStackTrace();        }        regist();    }    /**     * 处理服务器返回的APP版本号     * @param bundle     */    private void handleUpdateClientResult(Bundle bundle){        String json = bundle.getString(FunctionListEnum.UpdateClient.toString());        ObjectMapper objectMapper = new ObjectMapper();        if (null != json && !"".equals(json)){            try {                UpdateVO updatevo = objectMapper.readValue(json,UpdateVO.class);                if (null != updatevo){                    int serverversioncode = updatevo.getServerVersionCode();                    updateurl = updatevo.getUrl();//                    if ( !"".equals(serverversioncode)){                        if (versionCode 

2.更新接口

package com.tolly.parking.service.updateService;import com.tolly.parking.vo.UpdateVO;/** * 更新接口 * Created by zyy on 2017/7/24. */public interface UpdateService {    /**     *更新接口     * @param updatevo     * @throws Exception     */    void UpdateClient(UpdateVO updatevo) throws Exception;}

3.接口的实现

代码中的url是接口的地址

package com.tolly.parking.serviceImpl.UpdateServicelmpl;import android.os.Handler;import com.tolly.parking.Common.Constant;import com.tolly.parking.entity.UserUser;import com.tolly.parking.enumeration.CommandEnum;import com.tolly.parking.enumeration.ContentTypeEnum;import com.tolly.parking.enumeration.FunctionListEnum;import com.tolly.parking.service.updateService.UpdateService;import com.tolly.parking.util.FunctionUtil;import com.tolly.parking.util.InstanceServiceUtil;import com.tolly.parking.util.ServerDataExchangeUtil;import com.tolly.parking.vo.UpdateVO;import java.util.HashMap;import java.util.Map;/** * 更新接口的实现 * Created by zyy on 2017/7/24. */public class UpdateServicelmpl implements UpdateService{    private Handler handler;    private ServerDataExchangeUtil serverDataExchangeUtil;    public UpdateServicelmpl(Handler handler) {        this.handler = handler;        init();    }    /**     * 初始化     */    private void init() {        try {            serverDataExchangeUtil = new ServerDataExchangeUtil();        } catch (Exception e) {            e.printStackTrace();        }    }    @Override    public void UpdateClient(UpdateVO updatevo) throws Exception {        String url= Constant.UPDATEURL;        if(null != url && !"".equals(url)) {            String mac = Constant.MAC;            url = "http://" + url + FunctionUtil.getFunctionList(FunctionListEnum.UpdateClient.toString());            Map mapPara = new HashMap<>();            mapPara.put("mac", mac);            //创个userUser, 使之有token            InstanceServiceUtil.writeMap(UserUser.class.toString(), new UserUser());            serverDataExchangeUtil.handler = handler;            serverDataExchangeUtil.PostValue(CommandEnum.UPDATA_CLIENT, FunctionListEnum.UpdateClient.toString(), url, mapPara,ContentTypeEnum.Text.getContentType());        }    }}

4.服务器接口

接口返回的是新版本的版本号以及版本下载地址

package com.example.demo;import org.slf4j.Logger;import org.slf4j.LoggerFactory;import org.springframework.web.bind.annotation.*;import java.util.Map;/** * Created by JJH on 2017/7/27. */@RestController@RequestMapping("/bang")public class DemoController {    private Logger logger = LoggerFactory.getLogger(this.getClass());    @PostMapping("/getVersion")    public UpdateVO getVersionByMac(String mac){        logger.info("请求查询版本号接收的到参数为：" + mac);        // ==================  根据mac查询version的逻辑程序（一般入service服务类，也可以直接写）=====        UpdateVO updateVO = new UpdateVO();        APKcode apkcode = new APKcode();        Map map = apkcode.readAPK();        Object obj = map.get("versionCode");        int serverVersionCode = 0;        if(null != obj) {            serverVersionCode = Integer.parseInt(obj.toString());        }        updateVO.setServerVersionCode(serverVersionCode);        updateVO.setUrl("F:\\app-debug.apk");        return updateVO;        // ====================end===================    }}class UpdateVO{    private int serverVersionCode;    private String url;    public int getServerVersionCode() {        return serverVersionCode;    }    public void setServerVersionCode(int serverVersionCode) {        this.serverVersionCode = serverVersionCode;    }    public String getUrl() {        return url;    }    public void setUrl(String url) {        this.url = url;    }}

5.实体

package com.tolly.parking.vo;/** * 更新时服务器版本号VO * Created by zyy on 2017/7/25. */public class UpdateVO {    //服务器中APP版本号    private int serverVersionCode;    private String url;    public int getServerVersionCode() {        return serverVersionCode;    }    public void setServerVersionCode(int serverVersionCode) {        this.serverVersionCode = serverVersionCode;    }    public String getUrl() {        return url;    }    public void setUrl(String url) {        this.url = url;    }}

6.从服务器获取APK版本号

这个代码是网上查找的，自己修改运行。需要下载架包

AXmlResourceParser.jar

package com.example.demo;import org.apkinfo.api.util.AXmlResourceParser;import org.apkinfo.api.util.TypedValue;import org.apkinfo.api.util.XmlPullParser;import java.util.Enumeration;import java.util.HashMap;import java.util.Map;import java.util.zip.ZipEntry;import java.util.zip.ZipFile;/** * Created by zyy on 2017/8/1. */public class APKcode {//    public static void main(String[] args) {//        Map map = readAPK();//        System.out.println("package:"+map.get("package")+",versionCode:"+map.get("versionCode"));//    }    /**     * 读取APK     * @return     */    public static Map readAPK() {        String apkUrl= "F:\\app-debug.apk";        ZipFile zipFile;        Map map = new HashMap();        try {            zipFile = new ZipFile(apkUrl);            Enumeration enumeration = zipFile.entries();            ZipEntry zipEntry = null;            while (enumeration.hasMoreElements()) {                zipEntry = (ZipEntry) enumeration.nextElement();                if (zipEntry.isDirectory()) {                } else {                    if ("androidmanifest.xml".equals(zipEntry.getName().toLowerCase())) {                        AXmlResourceParser parser = new AXmlResourceParser();                        parser.open(zipFile.getInputStream(zipEntry));                        while (true) {                            int type = parser.next();                            if (type == XmlPullParser.END_DOCUMENT) {                                break;                            }                            String name = parser.getName();                            if (null != name && name.toLowerCase().equals("manifest")) {                                for (int i = 0; i != parser.getAttributeCount(); i++) {                                    if ("package".equals(parser.getAttributeName(i))) {                                        String packageName = getAttributeValue(parser, i);                                        if (null == packageName) {                                            packageName = "";                                        }                                        map.put("package", packageName);                                    } else if ("versionCode".equals(parser.getAttributeName(i))) {                                        String versionCode = getAttributeValue(parser, i);                                        if (null == versionCode) {                                            versionCode = "";                                        }                                        map.put("versionCode", versionCode);                                    }                                }                                break;                            }                        }                    }                }            }            zipFile.close();        } catch (Exception e) {            map.put("code", "fail");            map.put("error", "读取apk失败");        }        return map;    }    private static String getAttributeValue(AXmlResourceParser parser, int index) {        int type = parser.getAttributeValueType(index);        int data = parser.getAttributeValueData(index);        if (type == TypedValue.TYPE_STRING) {            return parser.getAttributeValue(index);        }        if (type == TypedValue.TYPE_ATTRIBUTE) {            return String.format("?%s%08X", getPackage(data), data);        }        if (type == TypedValue.TYPE_REFERENCE) {            return String.format("@%s%08X", getPackage(data), data);        }        if (type == TypedValue.TYPE_FLOAT) {            return String.valueOf(Float.intBitsToFloat(data));        }        if (type == TypedValue.TYPE_INT_HEX) {            return String.format("0x%08X", data);        }        if (type == TypedValue.TYPE_INT_BOOLEAN) {            return data != 0 ?
