How to Make Android Apps 6 : Fix Android Studio Errors

[@sriballa2002]

Derek, I have seen other video tutorials on android dev; your stand out in a way that I can just sit and watch all your tutorials at once..your lectures are really fun to watch and enjoyable. Thank you for that...every student should have a professor like you

[@derekbanas]

+sriballa2002 Thank you for all the nice compliments :) I'm very happy that you like them.

[@BrickleRex]

Hey Derek just wanted to say thank for these tutorials! What im doing is watching these tutorials and doing the same in kotlin. I have to say its much easier.

[@WirIez]

Hi man! Even though these videos are "old" they are helping me so much! Thank you so much! I have project in Android and your videos are really helping me out. Have gone through video 1-6 and I am starting to grasp things much better now. Can't thank you enough for putting these videos up :)

[@derekbanas]

It is nice to hear that they are helping :)

[@SpamDestroyer]

Thankfully since Android Studio is well out of beta, the first portion of this video probably won't apply to you! 5:10 is when he starts showing how to pass objects between two activities.

[@ARFallaha]

Great video! Loved the idea of whats next at the end. Also I'd recommend "for the future videos" that you show us in the beginning of the video what we're making "the final app". So that we can relate the code and views easily to the final result. Thank you very much Mr.Derek Banas, You're the best

[@derekbanas]

Abdul Razzak Fallaha Thank you :) Yes in future videos I show the app first.

[@AbhishekBalani93]

I had Android Studio installed but was doing development on Eclipse. I will do it on Android Studio now. Studio is better than eclipse right? It looks like. You're awesome for doing all this hard work for helping beginners like me. Even your videos are formatted properly. Thanks.

[@derekbanas]

Abhishek Balani You're very welcome :) Yes Android Studio is better now. It is my honor to be able to help others.

[@AbhishekBalani93]

Derek Banas I have commented on your blog on the post "Make an app and win phone". My comments are waiting approval. I hope you won't miss. :)

[@NikMelyt]

Dear Derek, Thank you for all your work to help us get into android world! I think I found a small issue with your Human class part. You use append but I think you should use setText to completely change/replace the text of calling_activity_info_text_view. When you use append it really appends but in your video the text is replaced.

[@Science2Student]

really great tutorial Derek, I am totally new to Android Studio, before I was using AI for making apps. but now Android Studio. when I try to Write '' Arabic '' Text inside a Label or '' LargeText '' NOTHING APPEARS '' I wonder if that's an issue of the Android Studio or am I doing anything wrong ? Android Studio is new, I think that a lot of people will try to search for Android Studio related videos in near future or even now, so I guess that making more of your amazing tuts will be great. I really hope you do more tutorials and hopefully I can see a tutorial on how to use CUSTOM Fonts on Android Studio. All the best :)

[@derekbanas]

I'm confused by what might be wrong because I just tested Arabic and it worked. Do you see any errors?

[@Science2Student]

Derek Banas it shows an error for not setting the string '' hardcoded string '' but it shows the same error for the English text but it SHOWS it. here's the screenshot. sorry if this is a weird question but I am zero at coding and willing to learn through java. i.imgur.com/qAJShY9.png if you had time, I hope you do a tutorial on using External '' Custom '' Fonts on Android Studio :) Thanks so so much Mr.Derek

[@Useruytrw]

Querido Coach, este video te ayudará en los problemas de producción. Dios los bendiga.

[@derekbanas]

Estoy muy contento de haber podido ayudar. Espero poder subir al siguiente mañana. Dios los bendiga.

[@edwardhandrich6043]

Hello Derek, Great videos, fast paced so I'm constantly engaged, love it. One question, why is the compiler compliance set to 1.6. I'm using Java 1.8 which should be backwards compatible.

[@derekbanas]

Java 1.7 is completely compatible with Android. For some reason on some OSs switching to 1.6 solves weird errors.

[@amitmoolwani778]

Hello Derek, thank you for sharing such an amazing knowledge on android with us...... I have question that when we rerun this app and feed the name again , it will append the data in previous one, i already have used setText() but its giving same result. How to get rid of that?

[@PatrickAllenNL]

What do you use to screencast again? are you really zoomin while recording..with a key or is that just a vocal reminder for editing after

[@derekbanas]

I zoom while I'm typing. I use Camtasia 2

[@PatrickAllenNL]

I also want to buy their sotware!! thats what most big youtubers use..great..but very expensive or...worth it..thats for sure

[@derekbanas]

PatrickDFTBA It isn't that bad. It is $99, but it goes on sale every once in a while. The crazy thing is that Mac osx used to come with a free screen capture tool that was deleted for some crazy reason with an upgrade. That is why i don't upgrade osx any more.

[@PatrickAllenNL]

Oh wait right..Camtasia studio is expensive...anyway I'm planning on buying it during the holidays..I run windows

[@earlcloydolongayo9347]

Hello Derek Thank you for the tutorials. I'm confuse. When running the application does the string "The calling activity was " erase on the SecondScreen after you append the bob name, height and weight?

[@derekbanas]

Yes it does and you're very welcome :)

[@jeffkehler16]

Derek Banas Have you ever tried using GenyMotion for the emulation before? I am using it and it is a million times better than the AVD. It has near native performance and there is no waiting for it to boot every time you want to test your app. You just leave it running in the background and its like you have a physical phone or tablet present. You can even play 3D games on it with great performance.

[@derekbanas]

No I have never used it. I normally test on my device. I just use the emulator for people that can't afford an Android device.

[@michaeljoannou5844]

Hi Derek, another great tutorial. Just wondering, on project structure, why does the file path include /contents/home for where the JDK is located? Also, I'm in danger of sounding very dumb but why do my file paths have back slashes and yours have forward slashes?

[@derekbanas]

Michael Joannou Hi Michael, Sorry about the confusion. My file slashes are different because I'm using OSX. OSX is basically Linux and so the slash goes in the opposite direction from Windows.

[@shreyabisht7456]

hi Derek, I am very new to android development ( still struggling with eclipse). Do you suggest android studio? whats the key difference between working on eclipse and studio? since i am just starting, would u suggest that i work with studio?

[@derekbanas]

Shreya Bisht I have used Android Studio exclusively for almost a year. There are 2 major benefits for me. AS was made just to make Android apps so there is no clutter. It also has everything I need installed so I don't have to mess with plugins like eclipse.

[@utkarshshukla5252]

Hi derek can you help me with this: I am trying to make a listview in android , in android studio it did not showed any red line (error), but on clicking run the app on my device showed blank screen ie no listview was generated

[@roxferesr]

This is greattt!, but it also pops the question "should I pass through objects or IDs?". When working with DB, I always get confused over which approach is better.

[@derekbanas]

roxferesr I use objects unless I'm working with a large amount of data that needs to be stored server side

[@roxferesr]

thanks for the clarification :)

[@ddouglascox7362]

Hi Derek, How do you get to that --- Welcome to Android Studio --- screen? You know the one that has --- Quick Start --- over on the right and 6 options under neath Quick Start of which configure is the 5th one down??

[@alaslipknot]

very exciting for the next video :D !! and the contest as well !!! i *really* hope my app (game) will give me the Note3 ^_^ !!! Thnkx a lot Derek :-)

[@derekbanas]

I'll try to upload it today. Best of luck in the contest :)

[@alaslipknot]

Derek Banas Hey Derek, based on the average time of your replies i am going to assume that you didn't have any notification from my side ^^ i just want to say that i have posted a question in your website at the contest page and it still waiting for a confirmation (for 3 days now) and i also send you a message on google hangout, can you please check :-) ? thanks

[@kyujinkim1377]

Well hello, Derek. I have an issue with running the android studio app, When I press run on a new project or an existing project, absolutely nothing happens. Also, I cannot get a preview of the code because of a "Rendering Problem". I have tried googling for solutions but couldn't find any. Can you give some advice?

[@felixgaray6461]

Android Studio 1.2, that was easy Works like a charm. I keep having to set my Project Encoding Settings to UTF8 everytime I open a new project, and Ideas on how to remedy that. The Project Encoding defaults to windows-1252 and if I set it to UTF-8 errors go away and it's fine, the IDE Encoding defautls to UTF-8 which I have not had any problems with.

[@bluepi7195]

Will you do C++ tutorials in the future?

[@derekbanas]

I'm planning a learn C++ in 30 minutes tutorial

[@orientleon]

Derek Banas how about Swift?

[@manuelgarridopena6244]

Ok i have to ask it. Do you use the same sound file on every video ending? It always sound exactly the same, and yet is so smoothly linked to the actual tutorial that im very confused.

[@derekbanas]

Manuel Garrido Peña Every video is 100% original. I used to work on the radio, so I guess I got used to delivering at the same tone?

[@manuelgarridopena6244]

haha yeah, well then nice job man! so pleeeease leave your message XD

[@firativerson]

Derek Banas i knew it!

[@dylanlobbregt6445]

Hey, Derek. I'm having a problem with using Edit Texts because they apparently cannot be rendered in API 20. I went in my SDK manager to install the other packages (like api 19) as you show in this video but all of the installations fail and nothing is done. The log shows a bunch of 'URL not found:' errors as well as ones that say "Skipping X; it depends on Y which was not installed". I'm trying to install exactly what you show you have installed in the video. Any ideas on how I might go about fixing this? Thank you!

[@derekbanas]

Make sure you are using api 19 and that you have this in the manifest file

[@dylanlobbregt6445]

Yeah. That will fix the edit text problem, but I can't install API 19 in my sdk manager because of the problem I talked about it my last comment.

[@derekbanas]

Dylan Lobbregt Try reinstalling. I can't think of any reason why you can't install API 19

[@dylanlobbregt6445]

Derek Banas I completed a fresh install of Android Studio for like the 5th time since I started using it lol. API 19 now works and it seems that everything else does as well (for now). Thanks a lot, Derek :).

[@IslarfPokemon]

Why do you have "result" and it set to 1? what's its purpose?

[@vaironxxrd]

Hey Mr. Banas, In relation to the upcoming phone giveaway, if we have no physical android device how can we test for all phones? Thanks!

[@derekbanas]

It just needs to run on a Nexus 7 device which is pretty generic. I just want to avoid country, or specific api issues so I can use the app.

[@RoniStiawan_physics]

Hopefully you cover Canvas and Drawable soon ~~

[@derekbanas]

Yes I'll definitely cover both. I'm going to cover everything this time.

[@jswaby]

Quick question.. Why use Serializable instead of Parcelable?

[@THE8SFN]

Hi, can you please make a tutorial on how to fix errors importing projects from Android Studio to Eclipse and vice-versa. YOU ARE GREAT, THANK YOU

[@derekbanas]

I'll take a look into that. I'll test different projects and see what the issue is.

[@THE8SFN]

thanks

[@gamingwithramolclashofclan8637]

Hey , I hope you are good , I have a question yesterday I started downloading android studio and downloaded almost every package but I have an error that tells me that the NDK ToolChain is missing , how can I solve this?i stayed like 1 hour and can't find a solution...

[@gamingwithramolclashofclan8637]

No worries I found it finally I needed to run it as administrator....wow I can't believe something that simple can stop me from running an app!!!

Hello, please I need some help with my android app. Here is the error: Skipped 91 frames! The application may be doing too much work on its main thread. I really don't know what to do. There's no video about this error.

[@derekbanas]

+bae suji You get that error when you try to make your program do to much. Is there a large calculation or are you pulling a lot of information from a database?

[@baesuji9521]

+Derek Banas Not at all, the main activity contains just xml code for now and I still haven't created any database for my login and register activities

[@doinkydeano2226]

i keep getting an error testing on a physical device "unfortunately, "name of app" has stopped. whats the main cause of this?? my app is very simple basically just placing buttons to change background colour. i am a windows user. i get the same error using the android studio emulator. api 21 my phone api is 17

[@derekbanas]

+Dean Webster That is the normal error on the phone or emulator. The Logcat will show the details of the error.

[@doinkydeano2226]

The logcat shows alot of erros.

[@doinkydeano2226]

But thanks i will have a closer look

[@shashwattewarishaz12]

I am making an app using videoview to stream videos from youtube and my device storage but I get an error at runtime which is somewhat like this error=EGL_SUCCESSpls help :(

[@vaironxxrd]

I hate to do this, but I was able to run Android Studio okish on my desktop and then transferred to my laptop to build the upcoming app, but I keep getting the following error... Error:Error retrieving parent for item: No resource found that matches the given name 'android:Theme.Material.Light'. Any ideas? (The google searches provide similar errors with no luck)

[@derekbanas]

Are you using Android L by chance? I'd stick with 19 for now. Verify that the /app/build.gradle file matches mine. Also check that the manifest file doesn't change the Android version. Tell me if that doesn't help

[@vaironxxrd]

That helped, bumped into a couple of more errors, but they have been easier to fix. Thanks again!

[@derekbanas]

vaironxxrd I just verified that Android 20 works on every OS now. They'll fix it soon enough.

[@Science2Student]

to add to your list is the disability of installing and downloading new SDKs from SDK Manager. the solution for this is to Run Android Studio as Administrator. I've always had this issue. and that step fixes it.

[@derekbanas]

Thank you for helping :)

[@Science2Student]

Derek Banas I should be the one to Thank you. this was just a tiny help ;)

[@ameyagodse4517]

Can you please let me know how to fix the v23\values-v23.xml file errors. i have tried everything and nothing works..

[@MahirTahir]

Professor Derek, I guess I do not have any luck on Android whatsoever. I have started with your older android tutorials (at that time I was using Win7) and my emulator just would not work on eclipse (indigo). I tried re-installing and everything but no. Now I am using Linux, as a newbie I am pretty impressed with it. I have installed Android Studio and again emulator just would not work. The error: ============================================= pkg: /data/local/tmp/com.example.asen52.third_android_application Failure [INSTALL_FAILED_OLDER_SDK] ============================================ Then I tried connecting my Nexus 7, I can see my device there but just would not work. Then my friend suggested using "genymotion" which is a fast emulator for Android Applications. Now it would not work too. The error I am getting ============================================= WARNING: linker: libdvm.so has text relocations. This is wasting memory and is a security risk. Please fix. pkg: /data/local/tmp/com.example.asen52.third_android_application Failure [INSTALL_FAILED_OLDER_SDK] ============================================ I am about to give up for some time if I get these errors on and on. Please help. I liked the appinventor, but since I was not able to mess up with the code it did not make sense to go forward after couple tutorials. But I agree they are good for understanding the basics may be I should finish them. BTW I was able to run them on my Nexus.

[@derekbanas]

Sorry about the frustration. I'm guessing the errors are occurring because of 2 issues. Make sure you have the same apis installed as I do through the SDK manager. Then make sure your /app/src/build.gradle file looks exactly like mine. I think that will fix that error. Tell me if it doesn't

Hi Derek, first I wanna thank you for the great videos. Second, it could be silly, but I think you should give ideas of apps to be build at the end of these tutorial videos, like an exercise. I say this because at the end of this video, I saw that layout and tried to build the same app like a training to myself. Anyway thanks for sharing your knowledge. Bye.
