项目介绍：cocos2dx跨平台游戏
项目需求：实现本地消息推送，需求①：定点推送；需求②：根据游戏内逻辑实现推送（比如玩家体力满时，需要计算后到点推送）；需求③：清理后台程序或重启后依然能够实现本地推送。
功能实现：由于IOS有一套比较成熟的UILocalNotification推送机制，这里主要说明Android下的实现。另外大家感兴趣可以看下第三方的推送：个推、极光、腾讯信鸽、百度云推送等，第三方多是要接入服务端，否则只能自己在第三方申请的应用的后台手动推送，另外第三方也不保证能100%所有客户端都能接收到推送。
1.全局定时器AlarmManager,可参考闹钟app，AlarmManager为系统级别，所以一般不会被清理掉，并把设定的提醒保存到本地(这里使用的SharedPreference,也可使用SQLite数据库存储)，开机重启时重新设置定时提醒。
/** * 消息推送 * noticeStr:通知内容 * tiemstamp:通知的启动的时间戳,单位为秒，定时器单位为毫秒 */ public int noticeCount = 0; public void pushMessage(String noticeStr, long timestamp) { //System.currentTimeMillis() 等于 Calendar.getInstance().getTimeInMillis()
long longTime = timestamp*1000;if (longTime > System.currentTimeMillis()) { Intent intent = new Intent(this, PushReceiver.class); //设置参数 intent.putExtra("noticeId", noticeCount); intent.putExtra("noticeStr", noticeStr); //timestamp参数 区别要注册的PendingIntent //receiver获取参数需要flag设置为PendingIntent.FLAG_UPDATE_CURRENT PendingIntent pi = PendingIntent.getBroadcast(FunmAndroid.this, noticeCount, intent, PendingIntent.FLAG_UPDATE_CURRENT); AlarmManager am = (AlarmManager) getSystemService(Activity.ALARM_SERVICE);; am.set(AlarmManager.RTC_WAKEUP, longTime, pi); //本地存储，手机重启，需要重新设置 SharedPreferences sharedPreferences = getSharedPreferences("funm_push", Context.MODE_PRIVATE); Editor editor = sharedPreferences.edit(); editor.putLong("tiemstamp_"+noticeCount, longTime); editor.putString("noticeStr_"+noticeCount, noticeStr); editor.putInt("noticeCount", noticeCount); Log.v("and_log", "put noticeCount: "+noticeCount); editor.commit(); noticeCount++; } }
2.接收广播：BroadCastReceiver，注意这里使用BroadCastReceiver，不要使用service。开机重新设置提醒。
package com.funcity.funm.push; import android.app.Activity; import android.app.AlarmManager; import android.app.PendingIntent; import android.content.BroadcastReceiver; import android.content.Context; import android.content.Intent; import android.content.SharedPreferences; import com.funcity.funm.FunmAndroid; public class BootReceiver extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent1) { // TODO Auto-generated method stub String action = intent1.getAction(); if (action.equals(Intent.ACTION_BOOT_COMPLETED)) { resetPush(context); } } private void resetPush(Context context) { SharedPreferences sharedPreferences = context.getSharedPreferences("funm_push", Context.MODE_PRIVATE); int count = sharedPreferences.getInt("noticeCount", 0); int noticeCount = 0; for (int i=0; i<count; i++) { long timestamp = sharedPreferences.getLong("tiemstamp_"+noticeCount, 0); String noticeStr = sharedPreferences.getString("noticeStr_"+noticeCount, ""); if (timestamp !=0 && !noticeStr.equals("")) { Intent playerIntent = new Intent(context, PushReceiver.class); playerIntent.putExtra("noticeId", noticeCount); playerIntent.putExtra("noticeStr", noticeStr); PendingIntent pi = PendingIntent.getBroadcast(context, noticeCount, playerIntent, PendingIntent.FLAG_UPDATE_CURRENT); AlarmManager am = (AlarmManager) context.getSystemService(Activity.ALARM_SERVICE); am.set(AlarmManager.RTC_WAKEUP, timestamp, pi); } noticeCount++; } } }
3.接收提醒并发起推送：
package com.funcity.funm.push; import com.fun.funm.R; import com.funcity.funm.FunmAndroid; import android.app.Notification; import android.app.NotificationManager; import android.app.PendingIntent; import android.content.BroadcastReceiver; import android.content.Context; import android.content.Intent; import android.support.v4.app.NotificationCompat; import android.util.Log; public class PushReceiver extends BroadcastReceiver { private NotificationManager manager; @Override public void onReceive(Context context, Intent intent) { // TODO Auto-generated method stub manager = (NotificationManager)context.getSystemService(android.content.Context.NOTIFICATION_SERVICE); int noticeId = intent.getIntExtra("noticeId", 0); String noticeStr = intent.getStringExtra("noticeStr"); Intent playIntent = new Intent(context, FunmAndroid.class); PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, playIntent, PendingIntent.FLAG_UPDATE_CURRENT); NotificationCompat.Builder builder = new NotificationCompat.Builder(context); builder.setContentTitle(FunmAndroid.getAppName()).setContentText(noticeStr).setSmallIcon(R.drawable.icon).setDefaults(Notification.DEFAULT_ALL).setContentIntent(pendingIntent).setAutoCancel(true); manager.notify(noticeId, builder.build()); Log.v("and_log","收到推送：onReceive: "+ noticeStr); } }
4.Receiver注册及权限
<receiver android:name="com.funcity.funm.push.PushReceiver">
<intent-filter>
<action android:name="com.funcity.funm.push.PushReceiver"/>
</intent-filter>
</receiver>
<receiver android:name="com.funcity.funm.push.BootReceiver">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
android:targetSdkVersion="18"
注意：
1.手机必须开启允许开启自启动权限定时推送才能在重启后依然生效。有些手机管理软件，如360会推荐关闭一些应用的开机自启动选项。
2.targetSdkVersion19以前是准时推送，貌似19之后为非准时推送，需要注意一下。
3.有些手机类型，比如小米，可能有5分钟以内的误差，可能是基于省电的考虑。
