<code>Intent.ACTION_DATE_CHANGED</code> and <code>Intent.ACTION_TIME_CHANGED</code> are triggered only when the user manually changes time or date, and they are not automatically triggered by the system.
I'm afraid you have to use <code>Intent.ACTION_TIME_TICK</code>, which is triggered by the system exactly each minute.

Yes, you must add

 &lt;action android:name="android.intent.action.DATE_CHANGED"&gt;&lt;/action&gt;
&lt;/intent-filter&gt;
</code></pre>

blocks|key|90973|text|在你的广播接收器onReceive方法中，我假设你有一个类似于下面的设置？|type|unstyled|depth|inlineStyleRanges|entityRanges|data|90974|@Override

++++...
}|code-block|syntax|javascript|90975|另一个需要考虑的问题是，您是否在IntentFilter中添加了适当的过滤器，例如...|90976|IntentFilter+filter+=+new+IntentFilter();

Inside your broadcast receiver onReceive method I am assuming u have a similar setup to the following?

<pre><code>@Override
public void onReceive(Context context, Intent intent){
 final String action = intent.getAction();
 if (Intent.ACTION_DATE_CHANGED.equals(action) || Intent.ACTION_TIME_CHANGED.equals(action)){
 // do stuff here
 }
 ...
}
</code></pre>

Another consideration would be did you add the proper filters to your IntentFilter such as...

<pre><code>IntentFilter filter = new IntentFilter();
filter.addAction(Intent.ACTION_TIME_CHANGED);
filter.addAction(Intent.ACTION_DATE_CHANGED);
</code></pre>

blocks|key|4873738|text|另一种方法，当日期改变时，我会采取行动。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4873739|实际上，当您在手机上手动更改日期时，Intent.ACTION_DATE_CHANGED只适用于提前日期，而不适用于以前的日期。此外，当您将时间设置为11:59并等待它变为00:00时，它不会触发日期更改的广播事件。|4873740|因此，我最终建立了自己的逻辑，将日期存储在共享首选项中，然后检查当前日期是在之前存储的日期之前还是之后(使用一些日期处理逻辑)，并基于此更新我的数据。|4873741|++private+void+takesomeActionIfDateIsChanged()+{

An alternative approach which I used to take an action when the date is changed.

Actually, the Intent.ACTION_DATE_CHANGED only works with the date of an advanced date and not with a previous date when you change the date on the phone manually. Also, when you set time to 11:59 and wait for it to become 00:00 to give you the broadcast event of the date change, it doesn't give you the trigger. 

So, I ended up making my own logic of storing a date in shared pref and then checking if the current date is after or before previously stored date (with some date processing logic) and updating my data based on that. 

<pre><code> private void takesomeActionIfDateIsChanged() {
 try {
 SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd", Locale.ENGLISH);

 long currentDateTimeInMillis = System.currentTimeMillis();
 Date currentDateWithMillis = new Date(currentDateTimeInMillis);

 String formattedCurrentDateWithOnlyDMYStr = dateFormat.format(currentDateWithMillis);
 Log.d(TAG, "formattedCurrentDate With Only DateMonthAndYear String : " + formattedCurrentDateWithOnlyDMYStr);
 Date formattedCurrentDate = dateFormat.parse(formattedCurrentDateWithOnlyDMYStr);

 String storedDateStr = mSpManager.getStoredDate(SPManager.STORED_DATE);
 Log.d(TAG, "storedDateStr : " + storedDateStr);
 Date storedDateOnlyWithDateMonthAndYear = dateFormat.parse(storedDateStr);

 if (formattedCurrentDate.after(storedDateOnlyWithDateMonthAndYear)) {
 Log.d(TAG, "The current date is after stored date");
 mSpManager.putNewDate(SPManager.STORED_DATE, formattedCurrentDateWithOnlyDMYStr);
 mCounter = 0;
 } else if (formattedCurrentDate.before(storedDateOnlyWithDateMonthAndYear)) {
 Log.d(TAG, "The current date is before stored date");
 mSpManager.putNewDate(SPManager.STORED_DATE, formattedCurrentDateWithOnlyDMYStr);
 mCounter = 0;
 } else {
 Log.d(TAG, "The current date is same as stored date");
 }
 } catch (Exception e) {
 Log.e(TAG, "exception : ", e);
 }
}
</code></pre>

blocks|key|2002758|text|你不需要任何许可。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2002759|为了在日期更改时收到通知，您需要注册到具有这些操作(以及ACTION_TIMEZONE_CHANGED)的BroadcastReceiver。|offset|length|style|CODE|BOLD|2002760|这是我做的一个解决方案：|2002761|https://stackoverflow.com/a/48782963/878126|2002762|entityMap|0|LINK|mutability|MUTABLE|url^0|0|S|N|1H|H|0|0|0|17|0|0^^$0|@$1|2|3|4|5|6|7|T|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|U|8|@$D|V|E|W|F|G]|$D|X|E|Y|F|H]]|9|@]|A|$]]|$1|I|3|J|5|6|7|Z|8|@]|9|@]|A|$]]|$1|K|3|L|5|6|7|10|8|@]|9|@$D|11|E|12|1|13]]|A|$]]|$1|M|3|-4|5|6|7|14|8|@]|9|@]|A|$]]]|N|$O|$5|P|Q|R|A|$S|L]]]]

You don't need any permission.

In order to be notified of date changes, you need to register to a BroadcastReceiver with those actions (and also <code>ACTION_TIMEZONE_CHANGED</code>) .

Here's a solution I've made:

<a href="https://stackoverflow.com/a/48782963/878126">https://stackoverflow.com/a/48782963/878126</a>

So I am in the process of trying to get a few intents to work for me, 
and am having problems on 2 specific intents. I searched these groups 
and the webs and can 't seem to find any more information than what 
the documentation gives me. 
It doesn't seem to matter if I declare the use of these intent in the 
manifest, or if I try to register a receiver in code, my receiver 
never receives the actions for <code>ACTION_TIME_CHANGED</code> or 
<code>ACTION_DATE_CHANGED</code>. 
As far as I can tell I should be receiving these actions in my 
broadcast receiver whenever the user explicitly sets the time/date by 
going to <code>"Settings" --&gt; "Date &amp; Time"</code> and then modifying the time or 
date 
Am I mis-interpreting what these actions are for? 
Are there any permissions that I need to declare in order to receive 
these actions? 
Does anybody worked with this actions ?

Is there some useful example where this actions are used, I could not find anything useful, there is plenty of examples of format change but not on actual time_date change...

Thanks in advance

ACTION_TIME_CHANGED or ACTION_DATE_CHANGED, can't make them work
