How to write to a Google Sheet from Android app programmatically - java

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?

Accessing a Property of an odt File?

I asked lately how i can access the meta data of a odt file and the most recomended way to do this was using the apache tika library.
I tried finding out how i can use this Libraries in Detail.
Reading through all this stuff I find that this tika service is pretty hard (at least for someone that is new to Programming like me)
So my question is if maybe someone has a link to a side where there is like a step by step tutorial on how to use it or maybe as a different method to do this. I realy dont want you to do my work but i am working so long on this now and did not get this far so i think its time to ask for help here. :(
I want to acces and set only one property of my file which is the "DocumentID".
Thank you for helping and sorry for my maybe bad english but it is not my foreign language.

Using JasperReport API

I got stuck with one problem since a few months ago. Now I recall it and stand still get the same problem. I want to make JasperReports Server can print report without exporting to pdf format. And I also got some clues for that. To do so, we need to use JasperReport API. However, I don't really know how to use that library. Also as I searched, I can see only this link: http://community.jaspersoft.com/wiki/jasperreports-library-tutorial but it's not describable.
Is it the right API?
If it is my right, have you ever experienced with printer as mention above?
Do you have sample process, sample code, or configuration?
Please help me solve. Any ideas, or solutions are really appreciated
Sakura
Take a look at http://jasperreports.sourceforge.net/sample.reference/printservice/index.html.
Note the name of the printers are commented. You will need to change the name to suit your needs.

Retrieving content of a txt file from URL to Android

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.
