How to Make Android Apps 2

[@saurabhchalke]

I just love your tutorials sir! Your videos are so well paced and cover so many different concepts. Can't find a better channel on youtube for CS!

[@derekbanas]

+saurabh chalke Thank you for the compliment :)

[@rhodelucas]

I love that you speed things up a little. I get lost sometimes, but it helps making things more exciting HAHA thanks for all this videos, btw.

[@derekbanas]

Lucas Rhode Thank you for the nice compliment :) You're very welcome

[@jakemalachowski4018]

I agree. It's nice for people who already have programming experience and are switching to Android development. I don't need a 5 minute explanation on what an int, float, and double are. He just tells you what you need to know to get up and running. It's great.

[@topekastatehospital8604]

The power of your tutorials lies in the Speed that makes the viewer want to understand more. Great MO

[@derekbanas]

Thank you for the nice compliment :)

[@TheKatanowaki]

These are a really good refresher for your older tutorials. I hope you go really in depth later on with more complex things. This is really good stuff, thanks!

[@derekbanas]

Thank you :) I promise I will cover all the complex topics. I'll make many apps as well.

[@michaeldmurphy]

Right on! Great video series!! I love how quickly you get through everything!!!

[@derekbanas]

Michael Murphy Thank you :)

[@RihabMersni]

I want to thank you for all your videos, you really have a great way of explanation that simplifies a lot the concepts.

[@derekbanas]

Rihab Mersni You're very welcome :) Thank you for taking the time to tell me.

[@Mr-R.R.]

great video! Learning much quicker then i would have at school. Keep it up!

[@derekbanas]

Thank you :) I'll try to put out 3 videos in the next 4 days.

[@BounnoyPhanthavong]

Dude, I'm in class learning how to build Android apps and I find these videos more useful than my professor!

[@hasansyed5572]

this is awesome dude! i always found app programming really intimidating because theres so many different files but this makes it simple

[@derekbanas]

+hasan syed Thank you :) I'm very happy that you like them.

[@mangesh2458]

Derek - your videos are amazing. They're filled with knowledge and to the point. Thank you for the work that you do. This helps so many people. Looking forward to more videos.

[@derekbanas]

***** Thank you for the nice compliments :) I'm very lucky to be able to do this.

[@kimtipatel7]

Can't say...how much grateful I am for your efforts of making these videos...You are life saver :-) Thank you very very much Derek Banas

[@derekbanas]

Kimti Patel You're very welcome :)

[@InfamousBlackGuy]

Gotta love the tone of voice; laughing while typing/watching a tutorial is quite enjoyable! P.S. android:inputType="textPersonName" doesn't capitalize the first character in the given name, instead use "textCapWords"

[@SpinningDoors]

I just want you to know I really appreciate these tutorials. Thanks man.

[@derekbanas]

+Manami You're very welcome :) Thank you

[@snidersweb3943]

Only on my second vid so far and although I do think you move a little fast its a great tutorial and I appreciate you taking the time to make the videos and post them online for free. Thanks!

[@derekbanas]

Thank you :) I'm happy to be of help

[@seanupton3170]

Thanks a lot for the tutorials. I'm sure it's time consuming, and you do an excellent job explaining things clearly. Appreciate the work.

[@derekbanas]

Sean Upton Thank you very much :) I have fun

[@logiconabstractions6596]

Create Activity & Extract string content = MIND BLOWN. But seriously, it's amazing that you actually highlight the things that will make it less of a PITA to code an app (yeah not a bit fan of Android coding... but then perhaps this way it'll feel less of a pita...)

[@derekbanas]

Thank you very much :) I'm happy I could help

[@dylaustin8]

i love your personality ! lol thank you so much for these

[@derekbanas]

Dylan Williams Thank you :) I'm a little goofy.

[@JacobJTan]

I have to say, your tutorials are the best tutorials I can find on the Internet! The learning curve is so comfortable, the pace is so good and everything is ordered in a way that is best for people to understand the content! Thank you so much for these amazing tutorials. Not to be too greedy, but after finish this series of android tutorials, do you have any suggestions for tutorials of more advanced topics?

[@derekbanas]

Jacob Tan Thank you for all the very nice compliments :) You're very welcome

[@Stefan06091991]

Awesome man! Don't know how people can dislike an educational video...

[@derekbanas]

+Stefan Cronje Thank you :)

[@rajk2400]

Wonderful Tutorials...They are easy to understand in detail and in depth...Thanks a lot for your Videos...

[@derekbanas]

Thank you very much :)

[@bennyboy968]

derek bananas, you know what man, your a good dude. we watch your videos for our class and, well, i did very very very poorly in the class because its very complicated and i'm not very smart, but you know what, derek, I enjoyed watching your videos, they brought some new perspective to my life. It made me realize that "you know what benny? androids aren't your thing" but that's ok because i still am hung like a horse.

[@derekbanas]

That's funny :) I'm glad you enjoyed the videos. Programming isn't for everyone, but check out this video for beginners if you want to try one more time kzbin.info/www/bejne/q5i6pmadrtmYaqs

[@BboyJuNg]

Awesome job. I'm subbing and recommending this series a friend! I would love to see some vids on Android Wear Development.

[@derekbanas]

Thank you :) I'll be covering Android Wear

[@russellmcnamara6107]

Derek i have been in jail for a year and thought of you and your videos every day.

[@namvarutube]

Derek, Thanks for your clear explanation! I realized you are able to transfer a lot of knowledge in a short period of time. Please keep go on and provide videos as mush as you can ;) Eventually I've decided to work on android seriously and your videos are helping too much, thanks.

[@derekbanas]

Mohammad Namvar You're very welcome :) I'm glad you like the videos. I plan on covering everything in these tutorials. Many more are coming.

[@sethsangop]

Fantastic video. Fast pace makes for efficient learning. Thank you!!

[@derekbanas]

sethsangop Thank you :) I'm glad you liked it.

[@lalo19851]

Your tutorials are great! Keep up the excellent work!

[@derekbanas]

Thank you :) Many more are coming.

[@balac1404]

You are doing such a wonderful job. Cheers. Love your tutorials. :)

[@derekbanas]

Bala C Thank you very much :) I'm glad you enjoy them.

[@frankerzed973]

Great vid! Learned a bunch, thanks.

[@derekbanas]

+Frankerzed Thank you :) You're very welcome

[@doppelganger1293]

25:15 Derek, why did you use method "valueOf" on class String, but not on object of String class?

[@victorluna8920]

valueOf is a static method. Static methods can be used without instantiating an object. This comment is a year old, hopefully you had already figured this out xD

[@doppelganger1293]

***** Yep, I figured it out by myself. Anyway, thank you for reply :)

[@TheBaliCompany]

Thank you! You helped a LOT with this series!

[@derekbanas]

You're very welcome :)

[@1000thezapito]

U r like a teacher man love ur videos

[@azzaromujic8166]

I watched 2 courses on coursera about android, but yours are much better ;)

[@derekbanas]

Azzaro Mujic Thank you :) I appreciate the compliment!

[@amanderge]

Really great job on these, your videos are terrific for my learning style. Thank you very much for these!!

[@derekbanas]

Serge Bénard You're very welcome :)

[@danesvarneelamagam8941]

Thank You for uploading these tutorials they are a great help.

[@derekbanas]

Danesvar Neelamagam You're very welcome :) Thank you

[@shadespirit11]

I really appreciate your efforts to provide us with these vidoes, they help me alot !

[@derekbanas]

I'm very happy that you like them :)

[@nuthinguseful]

Your videos are excellent Derek, on our masters course we used the Design patterns ones to get us through our exams! (pending result ;) ) Anyway, In regards to creating the private variables for the Buttons and then initialising them in the second part of the video, I commented this bit out as it does not seem necessary for it to work? Is initialising the buttons more of a good practice thing? Obviously in the example the EditText has to be to use it though Thanks for your hard work!

[@jagdeepshergill91]

Would love to thank you in person. Thanks a lot for sharing your knowledge and making it very clear to understand. Wish you Success in all!

[@TeamOrtus]

Excellent video... Thank you for taking the time to make this and all the others.

[@derekbanas]

Ben Howard Thank you :) You're very welcome

[@hwlm]

Hi Derek, Wonderful video - Clear and Concise! However, just a question - Around 12-13mins, you showed the example of layout_weight of 2 for Button 3 and layout_weight of 1 for Button 1 and Button 2. Isn't Button 3's width supposed to be 50% of the screen width since (2/2+1+1) = 50%? Thanks for clarifying!

[@javaercode6893]

Thanks for your amazing tutorials !

[@derekbanas]

+Javaer Code You're very welcome :) Thank you

[@Jlaubster]

Your tutorials are extremely helpful thanks you so much and keep up the good work!

[@derekbanas]

J_laubster Thank you :) I'm glad you like them.

[@byronovus]

Dear Sir, thank you for the videos. And thank you for your quick responses. It's amazing that you are still able to teach the basics, after so many years of programming (THIRTY YEARSSSS!!! WOW!!!). Thank you, again. Ok, I've got 2 questions. 1st question: LANAGUAGE SELECTION BY THE USER WITHIN THE APP: This was inspired by your lesson on translation. In the app I'm building, I want the user to be able to select the app language from within the app, irrespective of the language settings of their device. 2nd question: MAKING ROUND OR OVAL BUTTONS IN ANDROID STUDIO: Please kindly give your advice on the best way to create circular or oval buttons in android studio? thank you for your time.

[@bardazon]

they are very useful. even taking notes. great instructor. ill be sure to ask if i have any questions!

[@derekbanas]

thank you :) yes always feel free to ask questions. I answer everyone I get.

[@dickhole]

Thank you so much for these super clear and concise videos; also something about the way you talk amuses me (its a good thing)

[@derekbanas]

Kevin Norgaard You're very welcome :) I'm glad I could help

[@TheGamerSpunGe]

Kevin Norgaard know your feels, have been trying to find a way to to effectively learn this, somehow it all makes sense as UP goes through it :D

[@mattm7798]

Awesome vid. I already went thru myBringbacks tutorial series and while he knew alot, it was more like your buddy trying to teach you something where as this is like a professional course showing the best practices and very, well, professional. I can't say enough how much you should be charging for this stuff. It's that high of quality.

[@derekbanas]

Thank you for the nice compliments :) Those guys are way more popular then I so I appreciate it. Everything will always be free.

[@holdengreene9717]

love the videos. thanks for the great work!

[@derekbanas]

Holden Greene Thank you :) You're very welcome

[@alexking1954]

Thank you! I hope these come out more regularly now

[@derekbanas]

You're very welcome :) The next one will be up the day after tomorrow. I'll try to put one out every other day, but I can't guarantee that. I'll do my best.

[@kingwoodbudo]

Thanks so much for creating these very useful videos. I come from a C# background and used Xamarin to write an Android app but it turned out to be a memory hog and would crash often. Found that Xamarin has some issues. Now, I want to learn Java and do Android development using Java, so this has been a great help.

[@claudiubutnaru5096]

More videos like this derek.You are awesome.You bassicaly explain XML for us.Many thanks

[@derekbanas]

Claudiu Butnaru Thank you :) Many more are coming.

[@nazia1782]

These are really great videos and it has help me learn how to do it.

[@derekbanas]

Thank you :) I'm happy you liked it

Best tutorial. Thx Derek

[@derekbanas]

Marek Javůrek Thank you :) I'll continue the Android tutorials in the next few days

[@linucksrox2670]

Thank you for your time and expertise in making these and other awesome tutorials! What do you think about quickly previewing the finished app at the end of the videos? That would be a more tangible way to understand the results of the code, particularly toasts on this video.

[@derekbanas]

linucksrox You're very welcome :) As the tutorial continues I do that and will do that as the series continues.

[@HenryKaufman]

Can't wait for the next video!

[@derekbanas]

Part 3 is up now. The next one should be up on Thursday. i'm glad you like them.

[@HenryKaufman]

Derek Banas Awesome thanks!

Gr8 tuts, good job bro!

[@derekbanas]

Vinicius de Paula Thank you :)

[@Zukias]

the inputType="textPersonName" doesn't appear to work as intended, "textCapWords" does the job though

[@Papa91echo]

Very nice tutorial, your are keeping it simple.

[@derekbanas]

Thank you :) It will get complicated soon enough.

[@strangertodeath]

Your incredibly smart and gifted I owe you more then money your a hero.

[@derekbanas]

You're very kind thank you, but I promise I'm not that smart

[@Icekronik]

Awesome, about time for the second part :) Question time, a little stupid question but why do we define buttons and textviews 2 times? First via XML, and then second time via java code? Is it like "linking" between XML and Java code?

[@derekbanas]

Thank you :) There is no such thing as a stupid question. In the xml file we are creating the layout. It is good to think of the interface and the code that works with it to be completely separate from the beginning. So we create the widgets in the layout file. Then we create them in MainActivity and ask the R.java file for access to them by passing the id defined in the layout file. I'll do this many times so that it makes complete sense.

[@MayankParekh_nice]

Thanks a lot. You are absolutely wonderful.

[@derekbanas]

Mayank Parekh Thank you :) You are very kind to say that.

[@jacuiho]

Very nice video, very fun to watch, although you move so much and i often need to go back to see the whole picture to understand XD Either way thanks for the help!

[@ignouclasses8056]

Dear ur explaining method is good in this video.

[@derekbanas]

Thank you :)

at 21:20 onClick lightbulb does not give me the option that you use. i have >Create OnClick event Handler >Inject Language/reference >Override resources in other configuration

[@nathanm95]

I have the same thing -_-

[@isaacnicholaus4361]

Hello Derek, Am real enjoying and appreciating your works and the way u do it....I have an idea but it kind hard for me to implement it, is there any way u can help me? Thanks.

[@derekbanas]

Isaac Nicholaus Always feel free to ask me questions. I'm glad I could help.

[@elvis0288]

you are really good man thank you very much for this tutorials. one question when creating the project it give me the extends ActionBarActivity is deprecated i know it needs to be AppCompatActivity now but still it always create it as that

[@dnnyplss]

at the end of the movie, with the Toast example, you should use makeText instead of maketext (which is why it is showing red in the clip)

[@woblwoblwobl]

For me, when I'm typing in lines of text there are no suggestions being... suggested. For example, when you quickly selected textSize @ 13:42 in this video - this pop-up list does not appear for me. Having to type out everything is getting so frustrating. Any advice/solution? Running on Windows.

[@woblwoblwobl]

I see further down in comments there was a solution. IDE Settings -> Editor -> Code Completion Turn on Auto popup and Smart code completion> This still doesn't work for me. Anyone know why this may be? Also my lightbulb icon now seems to have disappeared! Any help appreciated.

[@derekbanas]

woblwoblwobl In part 6 I show how to fix most every Android Studio error I have been asked about.

[@woblwoblwobl]

Derek Banas Thanks for the reply. I've tried that video but it doesn't appear to address this. When I type in

[@ryanaxel01]

What are your thoughts on adding the onclick event to the actual button instead of writing an onclickListener in the code? The argument I've heard against it is that you are mixing the presentation layer with code. Is one way more efficient or easier to manage?

[@derekbanas]

ryanaxel01 I cover how to do both. I always use whatever makes my code more readable.

[@JangFoody]

Really very awesome tutorials.... Very nice work mate. Can you just give me an idea. I am preparing to make an app which gonna show some values(like remote monitoring) a device that working somewhere. So what you think it gonna use some server interactions? or mean can you give me an idea what things i might need to learn for that communications through android application.

[@derekbanas]

Vipul Gautam Thank you :) I have some videos on Android / PHP and web services already. I'll be making some NodeJS tutorials soon that will make it very easy to connect multiple devices. What type of device do you want to monitor?

[@JangFoody]

Derek Banas It's an earthquake intensity measuring device that works on Modbus TCP. I want to make remote monitoring android app. To monitor those values currently on the device or if any quake happened before then data stored in its memory or some kind of server. I made app for that in Vb.net but now have requirement for android or maybe later on to IOS just in case. But do you have some suggestion what i will be looking at. Is the picture is clear about this project?. How to make my android app stream those values ?what things i might be using?

[@derekbanas]

Vipul Gautam If you can output the data you want to a server text file or anything then you just need to read it into an Android app. I have tutorials on how to read text, xml, html, json, etc. in the tutorials on this page www.newthinktank.com/videos/make-android-apps/

[@Frootqloop1]

Hey. Thanks again these are wonderful. I'm going through them again and I just wanted to know what was the point of creating the buttons in the Java file? The answerYesButton and answerNoButton don't seem to be used and I'm making a program where I made buttons like these and it still works when I comment out them. Thank you!

[@malek6021]

Thank you very much you're doing a great job!

[@derekbanas]

malek IDRI You're very welcome :) Thank you

[@element74]

I don't see any changes to the app when you added a hint to each button. Where is the "hint" inside the app?

[@BINGOHINDI]

it is better is you say up front what are you going to do in the tutorial , for example " Sign in Page" and show your audience your final product, Also adding address will be great!

[@mynameisAdas]

Are you ever going to record 2d or 3d game tutorial for android?

[@derekbanas]

Adas Yes as soon as possible.

[@jagadeeshwarreddy4917]

in the last minute of video there is error in the toast.maketext code.

[@risteardob2095]

Hi Derek, I notice that in this video you define onclick methods in the activity file, i.e. "android: onclick = "somemethod"" (about 21 minutes into the video) It seems like a more straight forward way of defining an onclick function / method than the more conventional way of creating an onclick listener in the java code. Are there any downsides to your approach?

[@derekbanas]

Risteard O'B It all depends on the situation. Most of the time you define them in the layout file.

[@vincentcerezo7286]

Thank! I learned a lot i'll give a like and sub.

[@macfhlannchadharonan4668]

Hi Derek, which of the following should I be using as best practice. 1) XML onClick vs onClickListener 2) String usersName = String.valueOf(usersNameEditText.getText()); vs String usersName =usersNameEditText.getText().toString();

[@derekbanas]

+Macfhlannchadha Ronan IIt just depends on what makes for the most readable code for the first. I tend to use the 2nd option for your other question.

[@vaibhavsathe1411]

hey thanks for the video.this is a great video.

[@derekbanas]

Thank you very much :)

[@lemmy7926]

Hey Derek, I wanted to mention that there's an error that comes up since there's Android 5.0 now, which makes the tutorial hard to follow (especially causing phone preview issues in xml). It makes the IDE say that it couldn't find a resource with the name [blah]. This link helped (for everyone to see) stackoverflow.com/questions/26431676/appcompat-v721-0-0-no-resource-found-that-matches-the-given-name-attr-andro

[@lemmy7926]

And also, if you do that, the preview phone screen's buttons will have capital letters. To fix that, try pressing the android drop down button on the right of the translation button, and change the API level to something lower than 21 (e.g. 19 for Kitkat).

[@larissakunz391]

hi, could you tell me what version of android studio you are using so I can download that exact version because lots of this doesn't work on newer versions of android studio, thanks!

[@derekbanas]

I'm using 0.5.2 at the beginning and then go up to 0.6 tools.android.com/download/studio/canary/0-5-2

Great tutorial! One problem though... how can I change the language of the AVD so that I can check if my strings_es works fine?

[@dnnyplss]

+Daniel Steyer this is actually shown in the first video in this series

[@aliakram5192]

First of all I want to thank you for this most amazing series of android learning. Secondly i would like to share the error I encountered when I used onClick() function in one of the buttons in mainActivity.xml file. It does not give the option of createOnClickYesButton(view), it says OnClick Handler is missing. I could not find any solution on web kindly help me.

[@derekbanas]

Ali Akram You're very welcome :) That is an odd error. I haven't been able to track it down. You may want to re-install Android Studio and see if that fixes it.

[@aliakram5192]

It was resolved brother :) I developed a new project file and :) there it worked :) Thank you so much :)

[@derekbanas]

Ali Akram I'm happy to hear you fixed it :)

[@SergeantMcClain]

First off your tutorials are amazing I want to thank you for helping me pass my online java class with a B, my professor didn't teach us anything and I was completely lost until I found your Java series! Secondly, are you aware of a reason why in the 5.0 version of Android Studio the values-es folder doesn't appear in my hierarchy after I create it? I see it in windows explorer exactly where it should be but in the folder hierarchy in Android Studio it never shows up.

[@derekbanas]

SergeantMcClain Thank you :) I'm not sure about your question. I have the latest version of AS and I don't have that issue.

[@SergeantMcClain]

Derek Banas after playing around with it some I noticed a few things. First that AS can build this feature for you complete with the correct country codes (though it keeps throwing a "r" in front of it for some reason so I changed it back to ES in explorer and it looks to be fine) and instead of showing me folders it creates a file in the strings.xml folder with a "(ES)". I wonder if I need to change a setting somewhere to show the folders, but at least I know that I can manipulate the file structure externally and AS won't freak out on me. Thanks for the super quick response!

[@Hasstenichgesehn1]

SergeantMcClain It doesn't show the extra values folders in the "Android" view, as those are all shown as one and shows the language of each strings file in brackets behind it. To see all the folders as they actually are, click in "Android" above the folder structure and chose "Project". I stay with the Android view, as I find it easier to use.

[@nouffahad453]

can you please be my teacher lol love your videos, keep up the good work!

+Nouf ALMoajel Thank you :) I'm here for free when ever you need me

[@sparcsky]

Is it okay to have many nested linear layout? will that affect the performance of the apps?

[@derekbanas]

+Ian Parcon It is best to use as few as possible. That is why the grid layout is used for anything complex.

[@slavkosster]

Hey Derek Banas, input type textPersonName doesn't work for me. I don't know if it's because I have a custom keyboard, but it has no effect.

[@kevinnarul2266]

hello. can u do a new tutorial about calculations... such as division, percentages etc.. but not in a form of calculator.. :)

[@pasteywhiteboy8137]

Did you study code in Uni or College?

[@derekbanas]

+PasteyWhiteboy I did, but I went for electrical engineering. I didn't learn much in school, but I learned a lot on the job while working for a bunch of big companies. Back then it was the responsibility of the senior programmers to help the junior programmers learn.

[@pasteywhiteboy8137]

Derek Banas That's cool man, I enjoyed your video, keep doing what you're doing. I have another question, how would you add a ratings system to an app or website e.g. the public being able to rate new products?
