}

3、版本检测的状态类

/*** * @author wenjie*    检测版本的状态类*/
public interface UpdateStatus {/*** 没有新版本*/public static int NO = 1;/*** 有新版本*/public static int YES = 2;/*** 链接超时*/public static int TIMEOUT = 3;/*** 没有wifi*/public static int NOWIFI = 4;/*** 数据解析出错*/public static int ERROR = -1;
}

android 11？4、版本更新的service

/*** * @author wenjie*    下载新版本的服务类*/
public class UpdateVersionService extends Service {private NotificationManager nm;private Notification notification;//标题标识private int titleId = 0;//安装文件private File updateFile;private static HttpHandler<File> httpHandler;private HttpUtils httpUtils;private long initTotal = 0;//文件的总长度
    @Overridepublic void onCreate() {super.onCreate();httpUtils = new HttpUtils();updateFile = new File(SDCardUtils.getRootDirectory()+"/updateVersion/gdmsaec-app.apk");nm = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);notification = new Notification();notification.icon = R.drawable.ic_launcher;notification.tickerText = "开始下载";notification.when = System.currentTimeMillis();notification.contentView = new RemoteViews(getPackageName(), R.layout.notifycation);}@Overridepublic int onStartCommand(Intent intent, int flags, int startId) {//        VersionInfo versionInfo = (VersionInfo) intent.getSerializableExtra("versionInfo");
//        String url = versionInfo.getDownloadUrl();Bundle bundle = intent.getExtras();String url = bundle.getString("downloadUrl");PreferenceUtils.setString(UpdateVersionService.this, "apkDownloadurl", url);nm.notify(titleId, notification);downLoadFile(url);return super.onStartCommand(intent, flags, startId);}public void downLoadFile(String url){httpHandler = httpUtils.download(url,updateFile.getAbsolutePath(), true, false, new RequestCallBack<File>() {@Overridepublic void onSuccess(ResponseInfo<File> response) {// 更改文字notification.contentView.setTextViewText(R.id.msg, "下载完成!点击安装");
//                notification.contentView.setViewVisibility(R.id.btnStartStop, View.GONE);
//                notification.contentView.setViewVisibility(R.id.btnCancel,View.GONE);// 发送消息nm.notify(0, notification);stopSelf();//收起通知栏UpdateVersionUtil.collapseStatusBar(UpdateVersionService.this);//自动安装新版本Intent installIntent = ApkUtils.getInstallIntent(updateFile);startActivity(installIntent);}@Overridepublic void onFailure(HttpException error, String msg) {//网络连接错误if(error.getExceptionCode() == 0 ){// 更改文字notification.contentView.setTextViewText(R.id.msg, "网络异常！请检查网络设置！");}else if(error.getExceptionCode() == 416){//文件已经下载完毕// 更改文字notification.contentView.setTextViewText(R.id.msg, "xxx");// 更改文字notification.contentView.setTextViewText(R.id.bartext, "检测到新版本已经下载完成，点击即安装!");// 隐藏进度条
                    notification.contentView.setViewVisibility(R.id.progressBar1, View.GONE);Intent intent = ApkUtils.getInstallIntent(updateFile);PendingIntent pendingIntent = PendingIntent.getActivity(UpdateVersionService.this, 0, intent, 0);notification.flags = Notification.FLAG_AUTO_CANCEL;//点击通知栏之后 消失notification.contentIntent  = pendingIntent;//启动指定意图
                }// 发送消息nm.notify(0, notification);}@Overridepublic void onLoading(long total, long current, boolean isUploading) {if(initTotal == 0){//说明第一次开始下载initTotal = total;}if(initTotal != total){//说明下载过程中暂停过，文件的总长度出现问题  就把初始的文件的长度赋值给他重新计算已经下载的比例total = initTotal;}long l = current*100/total;notification.contentView.setTextViewText(R.id.msg, "正在下载：xxx");// 更改文字notification.contentView.setTextViewText(R.id.bartext, l+ "%");// 更改进度条notification.contentView.setProgressBar(R.id.progressBar1, 100,(int)l, false);// 发送消息nm.notify(0, notification);//              Intent intent = new Intent();
//                intent.setAction("cancel");
//                PendingIntent pendingIntent = PendingIntent.getBroadcast(getApplicationContext(), 0, intent, 0);
//                notification.contentView.setOnClickPendingIntent(R.id.btnStartStop, pendingIntent);
                }@Overridepublic void onStart() {notification.contentView.setTextViewText(R.id.msg, "开始下载：智慧海事");nm.notify(titleId, notification);}});}public static HttpHandler<File> getHandler(){return httpHandler;}@Overridepublic void onDestroy() {//下载完成时，清楚该通知，自动安装
        nm.cancel(titleId);System.out.println("UpdateVersionService----onDestroy");
//        try {
//            GdmsaecApplication.db.deleteAll(VersionInfo.class);
//        } catch (DbException e) {
//            e.printStackTrace();
//        }super.onDestroy();}@Overridepublic IBinder onBind(Intent intent) {return null;}
}

5、吐司的工具类

public class ToastUtils {  private static String oldMsg;    protected static Toast toast   = null;    private static long oneTime=0;    private static long twoTime=0;    /** * 吐出一个显示时间较短的提示 * @param context 上下文 * @param s  文本内容 */  public static void showToast(Context context, String s){        if(toast==null){     toast =Toast.makeText(context, s, Toast.LENGTH_SHORT);    toast.show();    oneTime=System.currentTimeMillis();    }else{  twoTime=System.currentTimeMillis();    if(s.equals(oldMsg)){    if(twoTime-oneTime>Toast.LENGTH_SHORT){    toast.show();    }  }else{    oldMsg = s;    toast.setText(s);    toast.show();    }  }  oneTime=twoTime;    }  
}  

6、获取sdcard根目录

public static String getState(){  return Environment.getExternalStorageState();  
}  /** * SD卡是否可用 * @return 只有当SD卡已经安装并且准备好了才返回true */  
public static boolean isAvailable(){  return getState().equals(Environment.MEDIA_MOUNTED);  
}  /** * 获取SD卡的根目录 * @return null：不存在SD卡 */  
public static File getRootDirectory(){  return isAvailable()?Environment.getExternalStorageDirectory():null;  
}  

7、版本检测的实体类

public class VersionInfo implements Serializable{  /** *  */  private static final long serialVersionUID = 1L;  private String id;  private String  versionName;//版本名  private int     versionCode;//版本号  private String  versionDesc;//版本描述信息内容  private String  downloadUrl;//新版本的下载路径  private String versionSize;//版本大小  public String getId() {  return id;  }  public void setId(String id) {  this.id = id;  }  public String getVersionSize() {  return versionSize;  }  public void setVersionSize(String versionSize) {  this.versionSize = versionSize;  }  public String getVersionName() {  return versionName;  }  public void setVersionName(String versionName) {  this.versionName = versionName;  }  public int getVersionCode() {  return versionCode;  }  public void setVersionCode(int versionCode) {  this.versionCode = versionCode;  }  public String getVersionDesc() {  return versionDesc;  }  public void setVersionDesc(String versionDesc) {  this.versionDesc = versionDesc;  }  public String getDownloadUrl() {  return downloadUrl;  }  public void setDownloadUrl(String downloadUrl) {  this.downloadUrl = downloadUrl;  }  }  

8、网络监测

 * 网络检查 * @author 00 * */  
public class NetworkUtil {  /** * 没有网络 */  public static final int NONETWORK = 0;  /** * 当前是wifi连接 */  public static final int WIFI = 1;  /** * 不是wifi连接 */  public static final int NOWIFI = 2;  /** * 检测当前网络的类型 是否是wifi * @param context * @return */  public static int checkedNetWorkType(Context context){  if(!checkedNetWork(context)){  return NONETWORK;  }  ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);  if(cm.getNetworkInfo(ConnectivityManager.TYPE_WIFI).isConnectedOrConnecting() ){  return WIFI;  }else{  return NOWIFI;  }  }  /** * 检查是否连接网络 * @param context * @return */  public static boolean  checkedNetWork(Context context){  // 1.获得连接设备管理器  ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);  if(cm == null) return false;  /** * 获取网络连接对象 */  NetworkInfo networkInfo = cm.getActiveNetworkInfo();  if(networkInfo == null || !networkInfo.isAvailable()){  return false;  }  return true;  }  
}  

更新安卓版本、9、json解析类

/** * json 和 实体类之间的相互转换 * @author 00 * */  
public class JsonUtil {  /** * 将一个实体对象  转换成一个json字符串  提示对象中可包含集合 * @param t 实体类 * @return */  public static <T> String beanToJson(T t){  Gson gson = new Gson();  String json = gson.toJson(t);  return json;  }  /** * 将一个json字符串 转换成一个实体类对象 可包含list * @param json * @param t * @return */  public static <T> T jsonToBean(String json,Class<T> class1) throws InstantiationException, IllegalAccessException{  Gson gson = new Gson();  T t = class1.newInstance();  t=gson.fromJson(json, class1);  return t;  }  /** * 将json字符串转换成一个json对象 * @param str * @return */  public static JSONObject stringToJson(String str){  try {  return new JSONObject(str);  } catch (JSONException e) {  e.printStackTrace();  return null;  }  }  public static String getString(InputStream is){  try {  ByteArrayOutputStream baos = new ByteArrayOutputStream();  byte[] buffer = new byte[1024];  int len = -1;  while((len = is.read(buffer)) != -1){  baos.write(buffer, 0, len);  }  byte[] byteArray = baos.toByteArray();  //String str = new String(byteArray);  return new String(byteArray,"utf-8");  } catch (IOException e) {  e.printStackTrace();  }  return "";  }  /** * 从assert文件夹中读取json文件，然后转化为json对象 * @throws Exception  */  public static JSONObject getJsonDataFromAssets(Context context,String jsonFileName) throws Exception{  JSONObject mJsonObj = null;  StringBuffer sb = new StringBuffer();  InputStream is = context.getAssets().open(jsonFileName);  int len = -1;  byte[] buf = new byte[1024];  while ((len = is.read(buf)) != -1){  sb.append(new String(buf, 0, len, "UTF-8"));  }  is.close();  mJsonObj = new JSONObject(sb.toString());  return mJsonObj;  }  }  

10、http请求类

/** * http  请求工具类 * @author winfo-wj * */  
public class HttpRequest {  private static HttpUtils http = new HttpUtils();  /** * 请求回调接口 * @author winfo-wj * */  public interface RequestCallBackListener{  /** * 请求成功  * @param resultData    服务器返回的结果数据 */  public void onSuccess(String resultData);  /** * 请求失败 * @param error 错误信息 */  public void onFailure(String error);  }  /** * get请求  * @param url 请求路径 * @param requestCallBackListener 请求回调 */  public static void get(String url , final RequestCallBackListener requestCallBackListener){  http.configTimeout(1000*10);  http.send(HttpMethod.GET, url, new RequestCallBack<String>() {  @Override  public void onSuccess(ResponseInfo<String> response) {  requestCallBackListener.onSuccess(response.result);  }  @Override  public void onFailure(HttpException error, String msg) {  requestCallBackListener.onFailure(msg);  }  });  }  /** * post请求 * @param url   请求地址 * @param params    请求参数 * @param requestCallBackListener   请求回调 */  public static void post(String url ,RequestParams params , final RequestCallBackListener requestCallBackListener){  http.configTimeout(1000*10);  http.send(HttpMethod.POST, url, params, new RequestCallBack<String>() {  @Override  public void onSuccess(ResponseInfo<String> response) {  requestCallBackListener.onSuccess(response.result);  }  @Override  public void onFailure(HttpException error, String msg) {  requestCallBackListener.onFailure(msg);  }  });  }  
}  

12、通知栏的布局

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"  android:layout_width="fill_parent"  android:orientation="vertical"  android:layout_height="fill_parent" >  <LinearLayout   android:layout_width="match_parent"  android:layout_height="match_parent"  android:orientation="horizontal"  >  <LinearLayout   android:layout_width="wrap_content"  android:layout_height="wrap_content"  android:orientation="horizontal"  android:layout_gravity="center_vertical"  >  <ImageView   android:layout_width="40dp"  android:layout_height="40dp"  android:layout_gravity="center"  android:src="@drawable/ic_launcher"  />  </LinearLayout>  <LinearLayout   android:layout_width="match_parent"  android:layout_height="wrap_content"  android:orientation="vertical"  android:weightSum="3"  android:paddingLeft="10dp"  android:paddingRight="10dp"  android:layout_gravity="center_vertical"  >  <TextView   android:id="@+id/msg"  android:text="正在下载：xxx"  android:layout_width="wrap_content"  android:layout_height="wrap_content"  android:textColor="#ffffff"  android:textSize="14sp"  />  <TextView   android:id="@+id/bartext"  android:layout_width="wrap_content"  android:layout_height="wrap_content"  android:text="0%"  android:textColor="#ffffff"  android:textSize="12sp"  />  <ProgressBar  android:id="@+id/progressBar1"  style="?android:attr/progressBarStyleHorizontal"  android:layout_width="match_parent"  android:layout_height="5dp" />  <!--   <LinearLayout   android:layout_width="match_parent"  android:layout_height="wrap_content"  android:orientation="horizontal"  >  <Button   android:id="@+id/btnStartStop"  android:layout_width="0dp"  android:layout_weight="1"  android:layout_height="25dp"  android:text="暂停"  android:textSize="12sp"  android:textColor="#ffffff"  />  <Button   android:id="@+id/btnCancel"  android:layout_width="0dp"  android:layout_weight="1"  android:layout_height="25dp"  android:text="取消"  android:textSize="12sp"  android:textColor="#ffffff"  />  </LinearLayout>  -->  </LinearLayout>  </LinearLayout>  </LinearLayout>
