I would like to be able to retrieve contents of a .txt file from the internet, and load it in an EditText. I tried using the code on this page: Reading Text File From Server on Android
It didn't work, as you might have guessed. I've read on numerous sites about this type of problem, but I can't get anything to work. Someone suggested AndroidHttpClient but I simply can't find any examples with this.
As I'm a newbie in Android programming, I would love if someone could please give me a small example.
This isn't so much of an Android question as it is a Java question. There are a few ways you could go about doing this, but the simplest might be using java.net.HttpURLConnection.

at first i have to say that my english isnt the best so dont blame me for that:).
I want to create a Food-App for Android-Systems which is able to get Information (like ingredients,preperation) of Webpages by downloading them through an Asynctask and saving them into a Database (SQLite).
I learned to work with JSON - based website and to show the results(after downloading the data) in a ListView. Now i have the problem that i dont have JSON in front of me and i have really no clue about how i can write a code which extracts relevant information of HTML - Webpage. Is it even possible?
Sorry if maybe of u may laugh now how unknowing i am but i try to learn:)
So i basically know much about Asynctask and Databases. But the point is i dont know how to connect them all with my specific problem.
Thank you in advance for all who will deal with my topic!
Try working with jsoup . Here you can find the jsoup library and full source code.
See an example at this site: http://www.vogella.com/tutorials/jsoup/article.html
Add jsoup to your project by adding this line to your app build.gradle :
compile 'org.jsoup:jsoup:1.10.3'
HTML is a XML based presentation of pages.
You can parse it with DOM, if theres repeated tags you may find easier to parse with SAX. But you will need to parse every information on the site and navigate trough the graph to extract what you want.
HELP! I have looked so long and read the documentation at https://developers.google.com/sheets/reference/rest/v4/spreadsheets.values/update on how to write to a Google Sheet but I still do not understand. I do not have any code examples because I do not know how to if it is any help my question is like the android version of the IOS Write Google sheet cell question. One thing I do know is that it seems that I need to use spreadsheets.values.update as it says in the linked documentation but I need help on implementing it.
Has anybody ever used this?
Well, does anyone know how to format a ValueRange, or know how to format the command spreadsheets.values.update?

Have a look at Java Servlets if no frameworks in use.
Here is a simple example
http://www.codejava.net/java-ee/servlet/multipartconfig-annotation-examples
You need to have a basic Java Servlets understandings for this.
Your question is pretty vague but here some steps/ideas that could help you in your homework :
You wants to download a file you could maybe seek here :
(it's assuming that you were given some GET url by your teacher) Get method.
-After having 'getted' the data you could write them in a file in a specific localisation (hard coded in a final variable or asked or
given in params depending on your level of skill).
-You wants to upload a file, using the same classes as in the link for the GET method you could use a POST method with the data to
upload.
Sorry it's pretty vague but i hope it at least helped you.
I am having trouble finding out what these .w files are and how to using them with my Java code: see Assignment1.zip at http://see.stanford.edu/see/materials/icspmcs106a/assignments.aspx
I would post a screenshot of my files, but I don't have enough "reputation points" to post an image on this site--I usually just read answers from others b/c I'm just learning. I can't open these .w files or else I would paste some of their contents in here.
For the past year, I've worked a good amount with Python and C++, but I decided to learn some Java from these free Stanford online lectures: http://see.stanford.edu/see/lecturelist.aspx?coll=824a47e1-135f-4508-a5aa-866adcae1111.
I've looked all over and simply cannot find out what .w files are, and I haven't been able to open them. I realize they're clearly worlds for the graphical robot to move around in, but I can't get the .java & .class files to function with these .w (or "world") files.
I would be happy to post some of my code in here as well, if you want. And I could post an image of the files & folders once I get a good enough reputation.
Could someone please help me?
You seem to be missing the documentation for karel.jar. There is already code for reading and working with these files, in sandford.karel.KarelWorld there is a load(File) method. But you will need to be working with the rest of the classes in the jar file, too, so you'll need to look for documentation (maybe given in the lecture videos?) or you'll have a very frustrating time.
I have download Grevill gervill.jar and with my existing code follow from:
http://www.jsresources.org/examples/MidiPlayer.html
Could anyone spare a little effort to write a tutorial on loading SF2 soundbank? I would cry without a tutorial on the web.
new SF2Soundbank(new FileInputStream(new File("sb.sf2")));
Then you just load all the instruments in the synthesizer.
Do some research.
If you want to learn how this code works, download it and try it. Generate javadoc API reference docs from the source. Try to figure it out. If you have problems getting it to work, post another question like this, but include specific details of the problem you are having.
You'll get a much better response this way. Stack Overflow is not someplace to find someone to do your research work for you.
