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;

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;
}
}
};
@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_INT_HEX) {
return String.format("0x%08X", data);
}
if (type == TypedValue.TYPE_INT_BOOLEAN) {
return data != 0 ? "true" : "false";
}
if (type == TypedValue.TYPE_DIMENSION) {
return Float.toString(complexToFloat(data)) + DIMENSION_UNITS[data & TypedValue.COMPLEX_UNIT_MASK];
}
if (type == TypedValue.TYPE_FRACTION) {
return Float.toString(complexToFloat(data)) + FRACTION_UNITS[data & TypedValue.COMPLEX_UNIT_MASK];
}
if (type >= TypedValue.TYPE_FIRST_COLOR_INT && type <= TypedValue.TYPE_LAST_COLOR_INT) {
return String.format("#%08X", data);
}

}
return String.format("<0x%X, type 0x%02X>", data, type);
}
private static String getPackage(int id) {
if (id >>> 24 == 1) {
return "android:";
}
return "";
}
public static float complexToFloat(int complex) {
return (float) (complex & 0xFFFFFF00) * RADIX_MULTS[(complex >> 4) & 3];
}
private static final float RADIX_MULTS[] = { 0.00390625F, 3.051758E-005F, 1.192093E-007F, 4.656613E-010F };
private static final String DIMENSION_UNITS[] = { "px", "dip", "sp", "pt", "in", "mm", "", "" };
private static final String FRACTION_UNITS[] = { "%", "%p", "", "", "", "", "", "" };
}
