关于安卓AlarmManager定时会失效的问题，请大神指教！

[sdssb]

网上找的资料，直接拿来用，但是发现用不了。又在网上找了很多代码，对着敲了一遍还是解决不了。AlarmManager.set一直没有调用onReceive方法。请大神帮我看看，哪错了。下面是我的代码。

public void setAlarm(long id){
        Log.e("AndroidBWL","setAlarm start...");
        String noticeDate=etDate.getText().toString();
        String noticeTime=etTime.getText().toString();
        Calendar calendar=Calendar.getInstance();
        calendar.set(Integer.parseInt(noticeDate.split("_")[0]),
                Integer.parseInt(noticeDate.split("_")[1])-1,
                Integer.parseInt(noticeDate.split("_")[2]),
                Integer.parseInt(noticeTime.split(":")[0]),
                Integer.parseInt(noticeTime.split(":")[1]));
        Log.e("AndroidBWL",""+(calendar.getTimeInMillis()-System.currentTimeMillis()));
        alarmManager=(AlarmManager)getSystemService(Context.ALARM_SERVICE);
        Intent intent=new Intent(AddBwlActivity.this,AlarmReceiver.class);
        Bundle bundle=new Bundle();
        bundle.putLong("id",id);
        bundle.putString("title",etTitle.getText().toString());
        bundle.putString("content",etContent.getText().toString());
        bundle.putString("noticeDate",etDate.getText().toString());
        bundle.putString("noticeTime",etTime.getText().toString());
        intent.putExtras(bundle);
        intent.setAction("ALARM_ACTION"+calendar.getTimeInMillis());
        PendingIntent pi=PendingIntent.getBroadcast(AddBwlActivity.this,0,intent,PendingIntent.FLAG_UPDATE_CURRENT);
        alarmManager.set(AlarmManager.RTC_WAKEUP,calendar.getTimeInMillis()+5000,pi);
        Log.d("AndroidBWL",""+calendar.getTimeInMillis());
        Log.e("AndroidBWL","setAlarm end...");
    }

接收代码：这里的日志一直没有打印

public void onReceive(Context context,Intent intent){
        Log.e("AndroidBWL","AlarmReceiver:onReceive");
        mIntent=intent;
        Bundle bundle=mIntent.getExtras();
        mNotificationManager=(NotificationManager)context.getSystemService(context.NOTIFICATION_SERVICE);
        mIntent.setClass(context,AddBwlActivity.class);
        mPendingIntent=PendingIntent.getActivity(context,0,mIntent,0);
        Notification.Builder builder=new Notification.Builder(context);
        builder.setAutoCancel(true);
        builder.setContentTitle(bundle.getString("title"));
        builder.setContentText(bundle.getString("content"));
        builder.setDefaults(Notification.DEFAULT_SOUND|Notification.DEFAULT_VIBRATE);
        builder.setContentIntent(mPendingIntent);
        Notification notification=builder.getNotification();
        notification.flags|=Notification.FLAG_AUTO_CANCEL;
        mNotificationManager.notify(1,notification);

    }

定时器的广播你注册在哪儿了。

[sdssb]

protected void onResume(){
        super.onResume();
        Cursor cursor=db.query("tb_bwl",new String[]{"id as _id","title","content","noticeDate","noticeTime"},null,null,null,null,null);
        adapter.changeCursor(cursor);
    }

这是我的代码，这样算不算注册了广播 网上看到有一个源码里是下面这样写的，我是不是也该这样写

protected void onResume() {  
        // TODO Auto-generated method stub  
        super.onResume();  
        // 注册广播  
        registerBoradcastReceiver();  
  
    } 

可以详细的说一下吗，我新手，不是很懂

 private void registerBoradcastReceiver() {  
  
        IntentFilter myIntentFilter = new IntentFilter();  
        myIntentFilter.addAction(ACTION_NAME);  
        myIntentFilter.addAction(ACTION_NAME2);  
  
        // 注册广播  
        registerReceiver(mBroadcastReceiver, myIntentFilter);  
  
    }  

我网上找的代码，我这样写对吗

/** * 开启闹钟 */ private void startRemind(){ Calendar mCalendar = Calendar.getInstance(); mCalendar.setTimeZone(TimeZone.getTimeZone("GMT+8")); mCalendar.set(Calendar.HOUR_OF_DAY, 21); mCalendar.set(Calendar.MINUTE, 0); mCalendar.set(Calendar.SECOND, 0); Intent intent = new Intent(this, AlarmReceiver.class); PendingIntent pi = PendingIntent.getBroadcast(this, 0, intent, 0); //获取闹钟实例 AlarmManager am = (AlarmManager) getSystemService(ALARM_SERVICE); if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT){ //大于4.4 am.setWindow(AlarmManager.RTC, mCalendar.getTimeInMillis(), 10, pi); }else{ // 小于4.4 am.setRepeating(AlarmManager.RTC, mCalendar.getTimeInMillis(), (60 * 60 * 24 * 1000), pi); } } public class AlarmReceiver extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { Log.i("测试", "闹钟响了"); Intent i = new Intent(context, AlarmReceiver.class); PendingIntent pi = PendingIntent.getBroadcast(context, 0, i, 0); //获取闹钟实例 AlarmManager am = (AlarmManager) context.getSystemService(ALARM_SERVICE); if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) { //大于4.4 am.setWindow(AlarmManager.RTC, System.currentTimeMillis() + (60 * 60 * 24 * 1000), 10, pi); } } } 要在AndroidManifest添加接收者： <receiver android:name=".AlarmReceiver" /> 因为大于和小于4.4的都有不同，楼主可以这样试试

public class MainActivity extends AppCompatActivity { private AlarmManager mAlarmManager = null; private PendingIntent idleIntent = null; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); init(this); sendMsg(this); } private void init(Context context){ context.registerReceiver(new BroadcastReceiver() { @Override public void onReceive(Context context, Intent intent) { System.out.println("收到广播啦"); Log.d("changzb","收到广播啦！"); } },new IntentFilter("TEST_INTENT_METHOD")); } private void sendMsg(Context context){ Intent intent = new Intent("TEST_INTENT_METHOD"); idleIntent = PendingIntent.getBroadcast(context,0,intent,0); Log.d("changzb","this.getClass().getPackage().getName() = "+(this.getClass().getPackage().getName())); Log.d("changzb","context.getPackageName() = "+context.getPackageName()); mAlarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE); mAlarmManager.set(AlarmManager.RTC_WAKEUP,System.currentTimeMillis()+20000,idleIntent); } } 这个是我写的，可以定时，你 参考一下。

原来是没有在AndroidManifest添加接收者： <receiver android:name=".AlarmReceiver" /> 总算解决了
