Looks to me like he is advising people to build an alarm app by checking every second if it should ring yet. That sounds terrible. It will be extremely taxing on the battery and the proccessor load for a simple alarm app.

Thanks for your comment Derek. This short video is just to quickly show how to implement a basic alarm clock. This video should be only a starting step. For a real App, lots of customization and robustness in the code needs to be implemented. Cheers Programmer World programmerworld.co -

Great video, the app is running great in the android studio but when open on my phone it doesn't work anymore, I mean it opens but the alarm doesn't ring, any fix for that?

@ProgrammerWorld 4 жыл бұрын

See in this tutorial App, only thing it is doing is comparing the system/actual time with the set time in the alarm clock. If it matches then it plays/invokes ringtone of your phone. So, if it is not working on your real phone then probably the system time which your phone is giving to App is in a different format than alarm time format received from clock. Very unlikely as mostly Android OS controls both of these formats. But certain OEMs may put a wrapper around original Android OS which may be causing it. It may be difficult to debug this situation, so I will recommend that you use toast command to display the two times while they are matched and then manually verify whether match is successful. Other reason could be that ringtone of your phone is either not set or is in silent mode/very low volume. Just check on that part as well. Lastly, I will recommend you can watch subsequent part of these tutorials using below links and try that code: kzfaq.info/get/bejne/iM1_pNCCyN_JpZ8.html kzfaq.info/get/bejne/g7idabGYv9LRdJc.html In case needed, complete source code of this tutorial is available at below link: programmerworld.co/android/create-a-simple-alarm-clock-app-in-android-studio Hope it works.

@ProgrammerWorld 3 жыл бұрын

The code shown in this tutorial is just a sample. For a complete functional Alarm clock, much further enhancement in the code of the App may be needed. However, to simply enable daily alarm, try to repeat the below timer every 24 hours. t.scheduleAtFixedRate(new TimerTask() So, just encapsulating it with another similar scheduleAtFixedRate method with 24 hours period should help. Hope the above helps.

@ProgrammerWorld 5 жыл бұрын

Hi Minsaa, That's because google has removed the Date Time option from the palette of Android Studio from version 3.1. It was there in 3.0. The workaround is to manually add the time picker and time clock code in the XML format (text file). I given the code in the previous comments as a reply to Affael around 2 months ago. See the previous comments.

Hi, Thanks for sharing your code. I went through your code. In first glance nothing looks unusual. However, I can see that in the AlarmTime() method, at line 61, you have used incorrect comparison sign in the IF statement. Instead of: if (alarmMinute > 10) please use: if (alarmMinute < 10) This comparison is done in the code because for the time below 10 minutes, the alarm time returns the minute value in single digit. So, to make it double digit (to be consistent with current time format), we concatenate the time for below 10 minutes with an extra 0. In your case since you have used the greater sign '>' in the IF comparison. Hence, it is concatenating an extra 0 for all the time greater than 10 minutes. Hence, making the minutes a 3 digit string. Which is not a supported format of time. Though I am not sure if this reason behind your nullpointer exception but this definitely needs corrected. Can you please do the above correction and let me know if it solved your problem? Else I will debug your code and try to figure out the reason for the failure. Right now I have not debugged your code as I will have to set your complete environment matching your class and object names. Please let me know if above does not solve your issue. Thanks Programmer World!

Der friend Thank you for notice that small mistake with ">". I have changed but it didn't help, I got NullPointerException again Then I used try catch block and got this @Override public void run() { try { if (currentTime.getText().toString().equals(AlarmTime())) { ringtone.play(); } else { ringtone.stop(); } } catch (NullPointerException e) { new Thread(new Runnable() { @Override public void run() { Toast.makeText(MainActivity.this, "Sorry! Something went wrong", Toast.LENGTH_SHORT).show(); } }); } } When I run the application doesn't crash and I got no exceptions, but the Alarm doesn't work, I set time, wait until equals to current time in mobile and nothing happens Thanks Programmer World!

@ProgrammerWorld 5 жыл бұрын

Check if you have provided access to ring tones to your app. You can check that in Apps permission under settings. Other check is for the volume of the alarm voice. If everything looks ok then last option will be to debug the code and check. You can first try to debug the code using the emulator which may be easier to do than debugging it directly on the smartphone.
