How to Make Android Apps 19

[@rjbarker2465]

Thank. You. No, seriously. You have NO IDEA how much I needed you to make this video. I sincerely appreciate it.

[@derekbanas]

Erin Barker Thank you for the nice message :) I appreciate all of the nice messages people leave for me!

[@ultrasamad]

In fact if I could write a small program that will loop through all your tutorials and hit the like button, I would have done it...lol..youtube probably might not allow me...bro u re awesome. keep it up!

[@derekbanas]

Ibrahim Samad That's funny :) Thank you. I'm very happy that you like the videos.

[@AbhishekBalani93]

Your new android videos are really good. Its really great that now you are covering other advanced topics. I have saved some of your videos for future reference as well. Keep doing the great job. And it's about to be a month since we are waiting for contest results. I hope I am not bugging you.

[@AbhishekBalani93]

And if you need suggestions about more topics to cover, then I might help. :D

[@loanafezzy9941]

Derek I love your video, however I'm confused about how you would implement this into a real app. For example: how would you make it so the user could choose the time of day they want to be notified? Or even if they want to be notified multiple times a day?

[@derekbanas]

Tomoko Desu Thank you :) You could set numerous times for the alert. You could also have the time dynamically change anytime the app is run.

[@toygar05]

Alarm button didn't work for me. Adding the following line to manifest file between the end of activity and application tags fixed my problem:

[@mirandalawson9477]

toygar05 Thank you so much for this.

[@theBrainyGeek]

+toygar05 Thankyou. Have been trying to debug for an hour.

[@matt2.019]

Thanks!

[@robertbrowne2578]

Tobi you wonderful man you! Nice catch

[@kiikiiworld]

You just got promoted to God status! thank you so much!

[@stjepankrpan779]

This is amazing Derek i learned a lot!!! Can i ask you just one thing? How to make AlarmMenager work after device reboot? I have switch buttons for 6:00 AM, 8:00 AM etc. and when i set them they work like charm but when my device reboot nothing is poping out... Thx for help!

[@derekbanas]

Stjepan Krpan Thank you :) Have you seen this stackoverflow.com/questions/12512717/android-alarmmanager-after-reboot

[@stjepankrpan779]

Derek Banas Thx for fast answer :) . I did solved my problem by making 2 new java class 1 Reciver with BroadcastRecever and in manifest promission RECEIVE_BOOT_COMPLETED and BOOT_COMPLETED for reciever and 2 java class that extends Services with onCreate where i put my onCheckSwitch method that i made to check if switches are pressed and if they are to set alarms again. Switches were memorized in SharedPrefrences...and it works now like charm...sry for bad English :P BIG THX 1 MORE TIME!!!

[@derekbanas]

Stjepan Krpan Great I'm glad you fixed it :) Always feel free to ask questions.

[@shaskies]

Hey Derek, Awesome tutorials. Question: 1. How many languages do you know? 2. Did you learn them in school or are you self taught? 3. How long have you been programming for? 4. Can you do tutorials on using APIs in your apps like Facebook's & Foursquare's in the future? Thank you.

[@derekbanas]

shaskies Thank you :) I have known and forgotten a bunch of programming languages over the past 30 years. I have used modula, assembler, pretty much everything. I went to school for engineering. I learned a lot on my own, but the high level stuff was mainly learned from employers. I'll do my best to cover the APIs you mentioned. I plan on making many more Android tutorials.

[@shaskies]

Derek Banas 30 years? That's crazy! As a 19 year old starting out I've got plenty to learn I guess. But your tutorials started me off, so thank you!

[@derekbanas]

shaskies You'll catch up to me eventually. It is much easier to learn today with all of the tutorials that are out there. I'm glad I'm able to help :)

[@kushalbhattacharyakush45]

Sir, in the last section when you use pending intent on the larm manger , i mean when we are using FLAG UPDATE current on the intent does it mean that it will not create the intent ie the main activity for the first time whenwe click that alarm notification?

[@FiddiTwo]

hi derek, im confused with trying to design a simple calendar type app. I have a Listview with date/times in it, i want it so that it automatically creates a countdown timer when there is 10 seconds until the time - would u use alarmManager for this ? Would u set an alarm for EACH item in the listview or just do one by one as they trigger ? thx as always, just watched this vid for the 2nd time :)

[@luisabcdefg7506]

Derek banas sence you have been making apps for some period of time. How hard is it to make apps like temple or detailed apps. Im just learning how to code and i always wonder if its hard to make apps even after you been coding for a while.

[@derekbanas]

luis martines It isn't that hard once you get used to looking at everything as a component that does its job. Like everything I think a good understanding of object oriented design and some diagrams makes it easier to understand.

[@MB-pt8hi]

Super video. Thanks I just added the TaskStackBuilder for the third button, so that the back button works for it to

[@derekbanas]

Thank you :) I'm glad it helped

[@samcostley897]

Hey Derek, I love all your videos and they are so helpful! Anyways, I was wondering if sometime you could make a video covering like industry standards for coding/Java. Industry standards as in the proper names for variables, documentation, and whatnot. Thanks!

[@Mattreds0x]

Derek Banas can you please explain to me why when I need to use the android support/appcompat libraries and when I don't need to? I seem to be confused as to why I wouldn't want to use the latest code and not a support library. I understand that the support libraries are basically porting some of the newer features of android back to the older versions, but I don't get when I should use the support library classes and when to use the built in classes. Thanks!

[@Mattreds0x]

One more question :) How did you learn all of what you know about android? Are there any books that you know if that go into depth and more advanced topics? Thanks and happy holidays!

[@derekbanas]

Mattreds0x Here is basically everything about the support libraries developer.android.com/tools/support-library/index.html

[@derekbanas]

Mattreds0x I learned most everything from reading the Android API and through experimenting. I have recommended the big brain academy book in the past. For some reason many of the Android books are full of errors. I'd say the best resources can be found in the API, on stack overflow and in random blogs.

[@Xselsiorlink]

Hey Derek, great tutorial again, I would like apply this to an app idea only thing is, i would prefer that the notification comes in when the person is online. Like a log in feature.. thanks for any advice because i want to incorporate the gps along with notification feature.

[@derekbanas]

brent swanson Thank you :) You could have your app update a database when they turn on their phone and then have the database send out a message to all others that the person is online. I need to make a NodeJS tutorial very soon to show how much easier it is to do this stuff.

[@Xselsiorlink]

Thank you while I learn the other vids I will gladly await that video. Thank you for your hard work

[@derekbanas]

brent swanson You're very welcome :)

[@MrStylesp9]

Hey Derek, just curious about how do you know so many programming languages. It's amazing.

[@derekbanas]

Styles P'yall Probably most importantly I have been doing this for 30 years. Most languages are basically the same. I do a lot of work in which my job is to fix broken code after a key employee leaves. That has forced me to constantly learn new languages and frameworks.

[@MrStylesp9]

Derek Banas Awesome. I wish to reach your level someday :)

[@StefoUltras]

Hello Derek, I have a problem with the app. When I enter it and press the button "Show Notification" the app just crashes saying the usual 'appname' has stopped working. Do you have any solutions? Thank you for the tutorials the are really helpful.

[@AquilesBlade]

How do i make a multiple alarm(like a alarm clock) using pending intent?

[@lllllll2886]

+Derek Banas halo,did u have tutorial about Music Player with its own database? Thanks

[@derekbanas]

Xin Lin The next video I upload will be on databases. It should be up tomorrow. I'll cover playing music and videos next week.

[@lllllll2886]

Ok....thanks

[@jumpmanjumpmanjumpman23]

in the MainActivity.java ActionBarActivity is now deprecated. You should use AppCompatActivity instead.

[@ernanimartins]

One question I can't seem to find anywhere is when I set an alarm for a future date, what if the user shuts down their phone or tablet and just open it later in time? Will it persist for the next boot? What if I do schedule an alarm and then come back and cancel after a reboot? Is that possible? Thanks a lot! Your videos are awesome!

[@derekbanas]

Ernani Joppert Have you seen this stackoverflow.com/questions/16534122/how-to-create-persistent-alarms-even-after-rebooting

[@ernanimartins]

Derek Banas I've seen such strategies, I wanted to be sure I needed to work with a SQLite before getting my hands dirty on that, but, hey, that post I haven't seen, and, it pretty much bogs down to copy and paste! Thanks a bunch!

[@iosifnicolae2]

Hi Derek. When announcing the winner of the contest? I'm so excited! :)

[@iosifnicolae2]

And i have one more question: How to power on device to fire an alarm. And thanks for this tutorial!

[@iosifnicolae2]

PS. I want to create a radio application and I need this features.

[@derekbanas]

Nicolae Iosif Your phone needs an FM tuner to pick up radio without an internet connection. Most phones have them, but they are utilized in different ways from what I know.

[@iosifnicolae2]

Derek Banas I want to create an internet radio application. But I don't know how to power on device at specific time.

[@derekbanas]

Nicolae Iosif The notification will work like all other notifications and will turn on the phone if it is set up for that.

[@CzajekTutorialowiec]

Hey Derek, Could you make a tutorial on making Android Apps with a new Material Design, animations etc. step by step? Just simple app with an action bar, sliding bar from left (like a menu), pages, transitions etc?

[@derekbanas]

Darek Czajkowski Yes that is coming very soon

[@CzajekTutorialowiec]

Ok, thanks a lot :D

[@YooporiumComics]

I would like to build an alarm clock app. Is that something that you could help me with?

[@jeremyjackson5562]

On the off chance that someone misses this like I did, make sure your app's build.gradle file has something like this: dependencies { compile fileTree(dir: 'libs', include: ['*.jar']) compile "com.android.support:support-v4:21.0.+" compile "com.android.support:appcompat-v7:21.0.+" }

[@derekbanas]

Jeremy Jackson Thanks for helping :)

[@michaelchheang9650]

Thanks for this great example!

[@derekbanas]

Happy to help :)

[@shubham01988]

Hello Derak, Can you do any android application on mongo db.

[@derekbanas]

Shubham Maurya I have a web services tutorial earlier in this tutorial series. The video I upload today will cover SQLite.

[@skullboneslayer]

Can someone please help me, Im getting this error Error:XML version "3.5" is not supported, only XML 1.0 is supported.

[@Hasstenichgesehn1]

Skullboneslayer Matthew Look through your xml files, they should say "" at the very top. That error sounds like one of your xml files says "...version="3.5"...".

[@skullboneslayer]

ok ill take a look thanks

[@nirangasandaruwan9559]

greate tutorial can you explain how to trigger an alarm on day of week as a example monday only,only weekend,only weekdays

[@nirangasandaruwan9559]

can you also explain How to create a custom notification on Android using remote views.

[@derekbanas]

niranga sandaruwan Here is a good example stackoverflow.com/questions/14542336/alarm-manager-triggers-notification

[@rannieangelo]

would you have tutorials on how to create calendar view for android? thanks derek :)

[@derekbanas]

Rannie Angelo Pinulan Sorry I haven't covered that yet. More Android tutorials are coming very soon.

[@rannieangelo]

thanks... i'll keep an eye out :)

[@saumitrabhardwaj2944]

Merry Christmas Coach. Please be my Santa and teach a ANT in a video course just like C++ God Bless

[@derekbanas]

Code Info Merry Christmas :) I plan on making a tutorial for every language over the next few months.

[@mirandalawson9477]

My app does nothing after 5 seconds. Am I the only one with this issue?

[@derekbanas]

Miranda Lawson Are you getting any errors in the LogCat?

[@mirandalawson9477]

Derek Banas No errors. Just nothing happens. toygar05 further down in the comments has a fix that worked for me (but the alarm generates no sound of any kind) : Alarm button didn't work for me. Adding the following line to manifest file between the end of activity and application tags fixed my problem:

[@theducksneezes4987]

Were you able to get it to work?

[@waseemsalie220]

Hi Derek, i got this app to run perfectly, how would I alter the code to trigger this alarm/notification the 5th day of every month?

[@TrivediKavit]

Hey, Can u make a tutorial on Push Notification in Android using PHP ?

[@derekbanas]

Kavit Trivedi Sure I'll cover that as soon as possible.
