do you have to have any programming experience prior i have knowledge in
java till object oriented programming only would it be enough :/
Hello Derek and thanks a lot for these tutorials!!! I’ve started from the
basics, but I’m not really able to understand this issue. Btw, I downloaded
Android Studio and it generates code a lil bit differently, not sure if
it’s the newer android sdk or what.
Anyways, here is the exception that I get at the end of this tutorial:
Caused by: java.lang.IllegalArgumentException: No view found for id
0x7f07003c (com.example.app:id/container2) for fragment
PlaceholderFragment{b1e383e8 #0 id=0x7f07003c}
I can make this go away, but I’d rather try to understand why that happens.
I pinpointed it to this:
if (savedInstanceState == null) {
getSupportFragmentManager().beginTransaction().add(R.id.container2, new P
laceholderFragment()).commit();}
But other than that I’m a bit lost :(
Thanks so much! I will definitely follow these tutorials 😀 I know Java,
but not in an Android context, so this will help lots.
This looks like an amzing tutorial but my eclipse doesn’t install/run right
:/
EXELENT VIDEO
i actually tried to make an app from the android website and it was soo
vague . this guy is beyond awesome, explains very well….here sir take my
like, lol
Hey Derek, not sure if you will see this but the app boots up normally on
my device (not the emulator) but when I type text into the text field and
press “send” nothing happens, the message isn’t sent to me.
Just wanted to know your thoughts on what may have happened.
Excellent idea to cram all of this in one space. It is great to remember
what all the files do. I actually did it with the new Android IDE.
Dang I know Java, but all of this Android stuff is kind of confusing me.
can you make a lottery app?
When I create the new Activity, Android Studio tells me to sync the gradle
files. When I do that, I get loads of errors in the
DisplayMessageActivity.java file, it can’t find the R.java file and so on.
Is this purely because of Android Studio? How can I mend this? Because I
really want to use this instead of Eclipse. I’m using Android Studio 0.4.6
(19 February) on Ubuntu 13.10.
P.S.: I truly love your videos, I think you’re awesome :D
Hey Derek, first of all, YOU ROCK !! Your tutorials are amazing !!
SO, I just got interested in developping Android apps and I’ve checked your
Android Inventer tutorials but I was wondering, if I want to start
developping apps with Eclipse, do I need to learn some Java language first
or skip directly to your tutorials ??
Excellent tutorial. Really nice way to get people started on Android app
development.
i dont have the android folder what should i do?
with me the activity_mail.xml, strings.xml, styles.xml & dimnes.xml look
VERY different than yours(they dont look as code as yours do), does that
matter?
Very well, thanks
Hi Roberto, really great tutorial…I have a question, I started to code in
Eclipse one Application, but the findViewById did not work, it did not
recognize the XML ID, I tried some of advice from Stackoverflow, but it did
not work, it starts to be frustrating, do you recomend to delede everything
and try to download and instal everything one more time? Thank you very
much.
drawable, drawable, drawable, drawable…u make my day lol
intent.putExtra(Extra_message, message); use of this?
Everything worked fine until I tried to run the emulator, then I got an
error message:
“Error generating final archive: Unable to get debug signature key”, and
the location is unknown.
Uuh finally I get something.Best tutorial
