operator 运营商信息管理包
用于运营商相关的流量信息读取、配置和管理
operator包文件结构-
OperatorModelInterface的定义和使用
OperatorModelInterface结构图- AbstractOperatorDataModel 抽象流量数据模型，定义了具体类里需要使用的回调集合类并且实现了注册和释放对应接口的方法
-
protected List<OperatorProvinceUpdater> mProvinceUpdaterList;
protected List<OperatorBrandUpdater> mBrandUpdaterList;
protected List<OperatorPackageUsageUpdater> mOperatorQueryResultUpdaterList;
protected List<OperatorAccountDayUpdater> mOperatorAccountDayUpdaterList;
* OperatorProvinceUpdater 运营商省份更新接口
* OperatorBrandUpdater 运营商品牌更新接口
运营商品牌更新接口，比如“全球通”，“动感地带”等，仅用于欧朋sdk
* OperatorPackageUsageUpdater 运营商流量使用情况更新接口
早起定义了1,2,4三个接口，后期使用接口3直接替代1,2但声明尚未删除
* OperatorAccountDayUpdater 运营商月结日更新接口
根据sim卡卡槽更新月结日，早期有绑定欧朋sdk，后面迭代过程中，欧朋不再支持月结日变更，全部切换到本地管理的月结日逻辑中
本包中定义的两个本地月结日管理相关类
* NativeOperatorDataModel 仅使用建立在原生流量统计基础上的流量模型进行流量数据管理
@Override
public void requesetPkgMonthlyUsageAndTotalInByte (final int slotId) {
checkThreadPoolExistence();
mThreadPool.execute(new Runnable() {
@Override
public void run () {
long lastCalibrateTime = AutoCalibrateUtil.getLastCalibrateTime(mContext.get(),
slotId);
long used = NativeOperatorDataManager.getPkgUsedMonthlyInByte(mContext.get(), slotId);
final long start = (used == OperaConst.PKG_USAGE_INVALID_VALUE)
? TimeUtils.getTrafficStaticsMonthlyStartTime(getAccountDay(slotId))
: lastCalibrateTime;
final long end = TimeUtils.getTrafficStaticsMonthlyEndTime();
long extra = mTrafficDataModel.getDataUsageWithinSpecificTime
(slotId, start, end);
boolean isLastCalibrateTimeLongAgo = ((System.currentTimeMillis() -
lastCalibrateTime) > 1000 * 60 * 1);
notifyMonthlyUsageAndTotalChanged(slotId, getPkgTotalInByte(slotId),
isLastCalibrateTimeLongAgo ? used + extra : used);
}
});
}
get数据使用情况的几个方法
@Override
public long getPkgTotalInByte (int slotId) {
return NativeOperatorDataManager.getPkgTotalInByte(mContext.get(), slotId);
}
@Override
public int getAccountDay (int slotId) {
return NativeOperatorDataManager.getAccountDay(mContext.get(), slotId);
}
@Override
public long getPkgUsedMonthlyInByte (int slotId) {
return NativeOperatorDataManager.getPkgUsedMonthlyInByte(mContext.get(), slotId);
}
NativeOperatorDataManager —— 一个用于保存本地流量值的SharedPreference管理类
* InvalidOperatorDataModel 空模式对应的流量模型，无sim卡时得到一个空模型，关键的接口实现直接返回无效值，可以参考调用端代码
@Override
public long getPkgTotalInByte (int slotId) {
return OperaConst.PKG_USAGE_INVALID_VALUE;
}
@Override
public int getAccountDay (int slotId) {
return OperaConst.ACCOUNT_DAY_INVALID_VALUE;
}
@Override
public long getPkgUsedMonthlyInByte (int slotId) {
return OperaConst.PKG_USAGE_INVALID_VALUE;
}
* OperaOperatorDataModel 欧朋流量服务对应的流量模型，对于移动、联通、电信三大运营商生效
调用欧朋sdk服务，进行短信校准回调注册，PackageQueryServiceAgent是一个抽象了欧朋sdk接口调用的可实例化的类
@Override
public void addQueryResultListener (final int slotId) {
if (null != mPackageQueryServiceAgent && mPackageQueryServiceAgent.isServiceBound()) {
addQueryResultListenrToAgentService(slotId);
} else {
if (null != mPackageQueryServiceAgent) {
mPackageQueryServiceAgent.addConnectionListener(new PackageQueryServiceAgent.ServiceConnectionListener() {
@Override
public void onConnected (IPackageQueryService service) {
Log.d(TAG, "recall add sms query result listener after service bound");
addQueryResultListenrToAgentService(slotId);
}
@Override
public void onDisconnected () {
}
});
} else {
Log.e(TAG, "package service agent is null, impossible to fetch query result.");
}
}
}
private void addQueryResultListenrToAgentService (int slotId) {
mPackageQueryServiceAgent.addQueryResultListener(slotId, this);
}
获取流量信息的请求方法
该方法直接使用本对象初始化时创建的线程池进行异步操作，所以回调不在主线程中，更新数据时需要注意
@Override
public void requesetPkgMonthlyUsageAndTotalInByte (final int slotId) {
if (null != mPackageQueryServiceAgent && mPackageQueryServiceAgent.isServiceBound()) {
startQueryPackageTotalAndMonthlyUsage(slotId);
} else {
if (null != mPackageQueryServiceAgent) {
mPackageQueryServiceAgent.addConnectionListener(new PackageQueryServiceAgent.ServiceConnectionListener() {
@Override
public void onConnected (IPackageQueryService service) {
Log.d(TAG, "recall start query after service bound");
startQueryPackageTotalAndMonthlyUsage(slotId);
}
@Override
public void onDisconnected () {
}
});
} else {
Log.e(TAG, "package service agent is null, impossible to fetch query result.");
}
}
}
private void startQueryPackageTotalAndMonthlyUsage (final int slotId) {
if (null != mThreadPool && !mThreadPool.isShutdown()) {
mThreadPool.execute(new Runnable() {
@Override
public void run () {
int total = mPackageQueryServiceAgent.getPkgTotalInKb(slotId);
int used = mPackageQueryServiceAgent.getPkgUsedInKb(slotId);
long extra = 0L;
long lastCalibrateTime = AutoCalibrateUtil.getLastCalibrateTime(mContext,
slotId);
if (lastCalibrateTime != AutoCalibrateUtil.DEFAULT_INVALID_LAST_CALIBRATE_DAY) {
long currentTime = System.currentTimeMillis();
// if last calibrate time is more than 20 minutes ago, we would like to double check
// monthly usage rather than just show monthly usage result obtained from sms.
boolean isLastCalibrateTimeLongAgo = (currentTime - lastCalibrateTime) >
(1 * 60 * 1000);
if (isLastCalibrateTimeLongAgo) {
// add used value.
final long start = (used == OperaConst.PKG_USAGE_INVALID_VALUE)
? TimeUtils.getTrafficStaticsMonthlyStartTime(getAccountDay(slotId))
: AutoCalibrateUtil.getLastCalibrateTime(mContext, slotId);
final long end = TimeUtils.getTrafficStaticsMonthlyEndTime();
extra = mNativeTrafficDataModel.getDataUsageWithinSpecificTime
(slotId, start, end);
Log.i(TAG, "last calibrate time is 20 minutes long ago, we add " +
"calibrated result with native saved value from last " +
"calibration till now value is " + extra);
}
}
notifyMonthlyUsageAndTotalChanged(
slotId,
(total == OperaConst.PKG_USAGE_INVALID_VALUE)
? OperaConst.PKG_USAGE_INVALID_VALUE
: total * LONG_BYTE_FACTOR,
(used == OperaConst.PKG_USAGE_INVALID_VALUE)
? OperaConst.PKG_USAGE_INVALID_VALUE
: used * LONG_BYTE_FACTOR + extra);
}
});
}
}
短信校准结果的回调处理
@Override
public void onQueryResult (JSONObject result) {
Log.d(TAG, "onQueryResult");
SmsQueryResult queryResult = SmsQueryResultUtils.analyzeAndSaveSmsQueryResult(mContext, result,
mSmsQueryStateManager);
if (queryResult.isQuerySuccessed) {
requesetPkgMonthlyUsageAndTotalInByte(queryResult.queriedSlotId);
}
for (SmsQueryResultListener listener : mOperatorSmsQueryResultListenerList) {
listener.onSmsQueryResultAnalyzed(queryResult.queriedSlotId, queryResult.queriedErrorCode);
}
}
各个get接口的实现方式
@Override
public long getPkgTotalInByte (int slotId) {
int total = mPackageQueryServiceAgent.getPkgTotalInKb(slotId);
return (total == OperaConst.PKG_USAGE_INVALID_VALUE)
? OperaConst.PKG_USAGE_INVALID_VALUE
: total * LONG_BYTE_FACTOR;
}
@Override
public int getAccountDay (int slotId) {
//int accountday = mPackageQueryServiceAgent.getAccountDay(slotId);
int accountday = AccountDayLocalCache.getAccountDay(mContext, slotId);
return accountday;
}
@Override
public long getPkgUsedMonthlyInByte (int slotId) {
int used = mPackageQueryServiceAgent.getPkgUsedInKb(slotId);
return (used == OperaConst.PKG_USAGE_INVALID_VALUE)
? OperaConst.PKG_USAGE_INVALID_VALUE
: used * LONG_BYTE_FACTOR;
}
- 本包中其他回调接口的定义
- OperatorDataModelFactory工厂类
根据sim卡是否为欧朋sdk支持的运营商来决定生成哪一个流量模型
public class OperatorDataModelFactory {
private static final String TAG = "OperatorDataModelFactory";
public static OperatorModelInterface getOperatorDataModel (Context context, int slotId,
boolean isSdkSupported) {
OperatorModelInterface mOperatorDataModel;
if (isSdkSupported) {
Log.d(TAG, "build opera operator model.");
mOperatorDataModel = OperaOperatorDataModel.getInstance(context);
} else {
// use native operator data model.
Log.d(TAG, "build native operator model.");
mOperatorDataModel = NativeOperatorDataModel.getInstance(context);
}
return mOperatorDataModel;
}
}

simcard 手机sim卡信息管理包
simcard包结构图- SimcardDataModelInterface及其实现类SimcardDataModel
可以说有一些多余，因为这个接口只有一个具体实现，应该是一个过度设计的问题
这个类主要负责获取sim卡的相关信息，使用接口定义，看的更加清楚吧，避免陷入实现细节
- SimcardDataModelInterface及其实现类SimcardDataModel
public interface SimcardDataModelInterface {
int SIM_CARD_ONE_INDEX = 0;
int SIM_CARD_TWO_INDEX = 1;

String OPERATOR_CODE_CHINA_MOBILE = "46000";
String OPERATOR_CODE_CHINA_MOBILE_1 = "46002";
String OPERATOR_CODE_CHINA_UNICOM = "46001";
String OPERATOR_CODE_CHINA_TELECOM = "46003";
String DEFAULT_OPERATOR_NUMBER = "";

String getSlotOperatorName(int slotId);
String getSlotOperatorNumber(int slotId);
int getSubIdBySlotId(int slotId);

void setDataEnabled(boolean state);
}
- SimStateListener的用途
public interface SimStateListener {
String SS_ABSENT = "ABSENT";
String SS_READY = "READY";
// 监听sim卡状态变化的广播回调，插拔卡是一种触发场景
void onSimStateChanged (String simState);
// 需求中需要更新运营商，但是单纯依赖sim卡广播回调，不能获取到运营商码，且运营商码的变更不会有sim卡状态广播发出，
// 所以自定义了一个运营商码变更事件
void onSimOperatorCodeChanged(int slotId, String simValue);
}
SimStateListener的调用端代码，定义在SimcardDataModel中，动态注册一个监听sim卡状态的广播，在广播回调中被处理
private BroadcastReceiver mSimStateChangeReceiver = new BroadcastReceiver() {
@Override
public void onReceive (Context context, Intent intent) {

SimStateListener在项目中的实现类
- smsquery 短信查询功能管理包
- SmsQueryStateManager 单例实现，用于整个流量模块获取和更新当前短信查询的状态
查询同时对卡1和卡2的状态做跟踪，可能出现的值及初始化方式都定义在下面代码中
- SmsQueryStateManager 单例实现，用于整个流量模块获取和更新当前短信查询的状态
public static final int SMS_QUERY_INITIALIZED = 100;

private int slotOneSmsQueryState = SMS_QUERY_INITIALIZED;
private int slotTwoSmsQueryState = SMS_QUERY_INITIALIZED;
实现中发现，完全只靠内存中对象做记录的话，会出现SmsQueryStateManager因为各种原因对象被重建导致短信查询装填出错，一直提示查询中的状况，所以存储设计为使用SharedPreference进行值的长时间保存
public synchronized int getSmsQueryStateBySlotId (int slotId) {

在主Activity，SecurityMainActivity退出时，也需要强制做一次数据重置，后续迭代更改了应用架构的话，要注意这一点
@Override
protected void onDestroy () {
super.onDestroy();
// when finish activity actively, reset sms query state as initialized.
if (hasRegisteredColorThemeChangeReceiver) {
unregisterReceiver(mChangeColorThemeReceiver);
hasRegisteredColorThemeChangeReceiver = false;
} else {
// do nothing.
}
SmsQueryStateManager sqm = SmsQueryStateManager.getInstance(getApplicationContext());
sqm.setSmsQueryStateBySlotId(
SimcardDataModelInterface.SIM_CARD_ONE_INDEX
, SmsQueryStateManager.SMS_QUERY_INITIALIZED);
sqm.setSmsQueryStateBySlotId(
SimcardDataModelInterface.SIM_CARD_TWO_INDEX
, SmsQueryStateManager.SMS_QUERY_INITIALIZED);
}
短信解析结果分析类结构
- statics 流量使用信息统计包
这个包是做第一个版本的流量详情统计和流量权限开关时实现的，目前因需求调整不会上线，需要对无用代码做清理，因为涉及到数据库操作，需要避免不必要的影响 - trafficalarm 流量告警功能管理包
目前的基本思路是在app中注册监听发生数据行为的广播，收到广播后根据当前是否在使用数据流量而启动流量使用状况分析的服务，在后台定时的查询流量使用状况，触发了异常条件后进行对话框弹出提醒
该服务直接继承于Service类，后续修改时要注意添加新分支后需要主动调用stop Service的相关方法流量告警功能结构图- TrafficUsageAlarmReceiver说明

- TrafficUsageAlarmIntentService说明
在onCreate时进行必要的资源初始化操作
@Override
public void onCreate () {
super.onCreate();
Log.d(TAG, "create usage alarm service");
mHandler = new Handler(this);
mSimcardDataModel = SimcardDataModel.getInstance(getApplicationContext());
mCurrentSlotId = mSimcardDataModel.getCurrentTrafficRunningSlotId();
if (mCurrentSlotId < 0) {
Log.e(TAG, "query data alert with invalid slotId.");
}
mOperatorDataModel = OperatorDataModelFactory.getOperatorDataModel(getApplicationContext
(), mCurrentSlotId, mSimcardDataModel.isSlotOperatorSupportedBySdk(mCurrentSlotId));
mOperatorDataModel.addTrafficUsageUpdater(this);
}
在onStartCommand时，调用OperatorModelInterface上的异步查询流量使用情况的方法
@Override
public int onStartCommand (Intent intent, int flags, int startId) {
mOperatorDataModel.requesetPkgMonthlyUsageAndTotalInByte(mCurrentSlotId);
mServiceStartedAction = intent.getAction();
return super.onStartCommand(intent, flags, startId);
}
在流量总量和月用量的回调时，进行是否需要发出流量使用警告的逻辑判断，跟据当前的slotId，对应slotId上面的流量警告配置状况做决定，如果需要进行弹框提醒，则发消息给主线程的Handler处理
@Override
public void onTrafficTotalAndUsedUpdate (long totalByte, long usedbyte, int slotId) {
if (null == mHandler) {
stopSelf();
return;
}
Log.d(TAG, "total is " + totalByte + " used is " + usedbyte);
if (totalByte < 0) {
Log.d(TAG, "total pkg usage returned is invalid");
return;
}
boolean isPkgRunOut = usedbyte >= totalByte;
boolean hasLeftLessThanTenPercent = ((totalByte - usedbyte) * 10 - totalByte) < 0;
if (ACTION_CONFIRM_WHETHER_TO_START_DATA_ALARM.equals(mServiceStartedAction)) {
final Context c = TrafficUsageAlarmIntentService.this;
boolean hasLeftLessThanTwentyPercent = (totalByte - usedbyte) * 5 - totalByte < 0;
// less than 30 MB.
final long LOW_DATA_LIMIT = 30 * 1024 * 1024L;
boolean isRemainingDataLessThan30Mb = totalByte - usedbyte < LOW_DATA_LIMIT;
if (isRemainingDataLessThan30Mb) {
TrafficUsageAlarmUtils.startTrafficUsageRunningOutService(c);
} else {
TrafficUsageAlarmUtils.cancelTrafficUsageRunningOutService(c);
}
if (hasLeftLessThanTwentyPercent && !hasLeftLessThanTenPercent) {
TrafficUsageAlarmUtils.startAlertTenPercentLeftService(c);
}
if (isPkgRunOut) {
TrafficUsageAlarmUtils.cancelAnyTrafficRunningOutCheckService
(TrafficUsageAlarmIntentService.this);
}
}
if (isPkgRunOut) {
// pkg run off.
if (TrafficUsageAlarmUtils.shouldAlertTrafficRunningOut(TrafficUsageAlarmIntentService
.this, mCurrentSlotId)) {
Message message = mHandler.obtainMessage(MESSAGE_ALERT_PKG_RUN_OUT);
mHandler.sendMessage(message);
} else if (TrafficUsageAlarmUtils.shouldAlertTrafficRunningOutAutoClose
(TrafficUsageAlarmIntentService.this, mCurrentSlotId)) {
Message message = mHandler.obtainMessage(MESSAGE_ALERT_PKG_RUN_OUT);
mHandler.sendMessage(message);
} else {
stopSelf();
}
} else {
if (hasLeftLessThanTenPercent) {
if (TrafficUsageAlarmUtils.shouldAlertLessThanTenPercentPkgLeft
(TrafficUsageAlarmIntentService.this, mCurrentSlotId)) {
Message message = mHandler.obtainMessage(MESSAGE_ALERT_TEN_PERCENT_LOW);
mHandler.sendMessage(message);
}
} else {
stopSelf();
}
}
}
主线程中的Handler回调，用于真正启动警告窗口
@Override
public boolean handleMessage (Message msg) {
switch (msg.what) {
case MESSAGE_ALERT_PKG_RUN_OUT:
boolean isAutoCloseNetworkEnabled = TrafficUsageAlarmUtils
.getAutoCloseNetworkWhenDataRunningOut(this, false, mCurrentSlotId);

showPkgRunningOutAlertDialog();
}
break;
case MESSAGE_ALERT_TEN_PERCENT_LOW:
showTenPercentLeftAlertDialog();
break;
default:
stopSelf();
break;
}
return false;
}
对于对话框提醒的部分，设计了提醒过之后就不再提醒的功能，以及发生过流量校准，及手工修改流量后，清空不再提醒标志的功能，后续涉及到相关逻辑的修改，以及增加新功能时，需要关注到
目前我想到还没做的 重新设置开关后，是否需要重置 已发出对话框提醒的标志
public static boolean getTenPercentPkgLeftAlert (Context context, boolean defaultValue, int slotId) {
if (SimcardDataModelInterface.INVALID_SIM_SLOT_ID == slotId) {
return false;
}
return getTrafficUsagePreferenceBooleanValue(context,

public interface TrafficDataModelInterface {
long getDataUsageWithinSpecificTime (int slotId, long start, long end);
long getDailyUsageBySlotId (int slotId, long monthlyUsage, int accountDay);//不再需要日已用提醒，所以该接口实际已无用了
void clearTrafficData();
}
