[Q] Idea about how to get values from a table - Android Studio

Hello!
As some could see in my other topic, I'm learning about android studio to make an app with some maths to help me with my job.
Well, in one specific case, I need to search and get values in a table, based in a reference. Its basically like the VLOOKUP/HLOOKUP function in Excel.
My doubt is the ideal way of doing that, is there any kind of table inside the android studio, like a container or something ? Or I should use a data base ?
Below is the same math, on excel, that is the base that I'm creating the app for android, in this case is a simple table, but in some cases are many values:
The attachment 001.png is the list where I select the materials Standard, and then I get the 2 values σt and σe from the table.
The attachment 002.png is the table I am looking for the values:
Sorry about this kind of question, but I'm just reading a lot, looking for tips leading me to an ideal way of doing it, but its a little hard in the beginning.
Thanks in advanced.

Conversion
Hey from your question , I undestood that you are looking for ready table to give values.
As i see you are getting values in excel.
1) There is no direct conversion table available into android studio.
2) You can use library project import if you require familiar conversion tables.
3) If in excel you make your own conversion method . apply same into Anddroid studio.
What more , share your method or query breif.

Hello,
Thanks for replying satyampv,
Actually my doubt isnt about conversion, I said about excel because I'm used to work with it. And its so easy to use vlookup there that I was wondering if would have something like it on android studio .
If I have to put some huge table in a database here on android, it's ok, I accepted that I would have to do it. But the doubt is if I really have to use a database, or if exists other way to look up for values in a table. Like you said "2) You can use library project import if you require familiar conversion tables.", is that an alternative for a database ?
Or should I just forget those "normal tables" from my mind and use SQL lite ? Because is just to look for values, just read, I don't need to write neither do any changes in the table after it's created.
Thanks in advanced, again.

[REQ] XML builder for Raph

Hi all
I was wondering how many people here would like to have some sort of way to build an xml which upon completion of a ROM update (which for some us are only day's apart) would change a load of settings to what we want for them
this is just a concept at the moment and i would like to work with someone or the community as a whole to produce a program to do this
the concept i have is as follows:
a simple windows exe Window which has inside it drop down menu's for all of the settings possible (cleartype/text size/regional settings/time zone/notification settings) fields (username for email/password/server addresses/screen name)
and if possible, something to allow us to drag and drop CAB file's into a window which would then also package up the cab's into a folder and spit out/generate the relevant SDCONFIG.txt file
is this at all possible? is there much interest in this?
I can go through and try to find as many of the settings possible and attempt to perhaps find the relevant registry settings even
i would really like to get the ball rolling with this, im sure it could work really well, not only on the raphael, but also on other devices perhaps
please post any interest on this project/concept here and i would really like to do something about this, im about to go and figure out the best way to even code this, however my coding knowledge is about zilch.lol!
.PROVXML files are the ideal place for last minute configuration changes. I'm just starting to explore this avenue and I've found tremendous flexibility in what one can change.
Have a look at the following information ... right from the source
Provisioning Using a ROM Configuration XML File
http://msdn.microsoft.com/en-us/library/bb737254.aspx
Configuration Service Provider Reference for Windows Mobile-Based Devices
http://msdn.microsoft.com/en-us/library/ms889539.aspx
There's also some excellent thread on XDA ... you'll have to do a bit of searching for them.
HTH,
have you looked at oemizer?
Assume this is the one you mean: http://tiermann.net
... takes the fun out of doing this the "manual way"
Cheers,
I don't use it personally. I came across it when I was learning with my M3100 (Hermes) and it provided a few useful insights at the time when I disected what it had created. I found a few problems and don't use it, but it seems like a similar attempt to what the OP is trying to achieve.
many thanks for the replies
im just looking into the oemizer that was posted and see how that works, however, i get the impression that its for rom cooking
Hi duke_stix,
That's where it's often used ... although, I have come across some posts about utilities that can re-initiate Provision XML files already present on the device or new ones placed on an SD card.
*EDIT* - Some examples

Cheers,
I have not seen anything that does exactly what you suggest, but things to look at that are maybe related include
Sashimi
tier-autoinstall (or something like that)
They run the files but don't create them.
You can always just export the reg values and then import them after you flash...
or use a reg to xml program to add it to SDConfig
I'm working on a new app right now that might have the potential to cover what you're asking for, but the exact features necessary to pull off at least a part of it won't be available in the first release. Keep an eye out on the D&H forum in anywhere from a week to two weeks when I post it up there.

How can I make a simple game or app?

I've been programming for 3-4 years, about 1-2 of those years in C++(the rest in html, php, gml, js, and crapy stuff like dat). No Java, but I've heard its really easy to learn especially if you already know C++.
anyways, I've read the google tutorials and they haven't helped me since they make you download code instead of writing it (like the notepad tutorial).I've also seen all the videos that explain how android works, and I've read the stuff about it. I just want a tutorial that walks you through the process of programming an application.
basically what I want to learn is:
- How to tell if the user pressed a button, or interacted with a view
- draw an image to the screen
- open and close activities, like for a game you switch from the 1st level to the menu
- How to save data to a file, or database(whichever is best)
and things like displaying a list of items, or an alert and stuff like that.
I already setup eclipse and ran the Hello, Android application in the emulator AND my G1 with adb. So I just need to learn how to write the code
My goal(currently) is to make a picture on the screen move to the right when the user presses something(button, key, trackball, screen), but with my code, not cut & paste. I'll just turn that into a game later.
please help me with this, I've always wanted to develop apps for android(ever since I heard of it ). sorry if this sounds like a retarded question, but I've searched everywhere and I haven't found a good tutorial, and I cant buy a book
PS. I use the eclipse plugin for visually designing the layouts
http://java.sun.com/docs/books/tutorial/
I don't exactly remember from my HTML java applet days, but you can write straight to vm's frame buffer and write a simple program to change the position of the element scrolling it either way you want. Also, java input in html applets can be aided with javascript, so i used javascript to listen for user input and then have java respond to it, but that was over 10 years ago and I dont remember now T_T
really? thats helpful...
EDIT:
I've already read these tutorials on java: http://www.freejavaguide.com/corejava1.htm

Android Access Database

Here we go:
I use a number of Microsoft Access Databases for my work, and each one is intensely coded and designed and basically run like actual programs. What I am looking for is to be able to take these databases with me. Now understanding that Microsoft and Android are two completely different beasts, what I really am looking for is the ability to take the tables (I use all Back-end database so all my tables are in a completely separate file then all my forms, queries, and reports) and the data with me and be able to run them in a program on Android that keeps the relationships and fields and all of that sort of stuff.
Now what would be great is the ability to use forms (even if special forms for android need to be made), run queries, and even be able to run reports and print as PDFs.
now I know how to code in VBA, hence the extensive coding I have done in Access, so anybody willing to WORK WITH in creating an Android Program to basically be an extension of Microsoft Access please contact me. Please not I use the words WORK WITH loosely, while I am trying to learn how to Program for Android, I currently do not have a computer that I can use to develop programs for android on, and well I would be only able to create the "Hello World" starter program and this project seems a slight bit more complicated. But what I can bring to the table is real world experience in testing and using the program day in and day out, a number of already existing Microsoft Access Databases ranging from Complex to Simple that I use every day. Really a program that can run Microsoft Access Tables on Android would be really useful to me and I am willing to do anything to help make this happen.

I think we must have the same job
Android utilizes an sqlite database engine and it looks like sqlite already offers a conversion utility HERE. The real question would be how to get the data in and out of the phone. Regarding forms, they definitely would need to be custom built.
Thanks this is deffenetly a start, From what I can tell this This Looks to be the most promising, It looks like all you would have to do is put a MS Access Database file on your SD CARD and have a program access it. That way you copy it back and forth. Unfortunately it doesn't support Access 2003, but I can save down. I also got a lot of learning to do in programing Java programs.
Forms would be as simply as making a program, this is great thanks much

I would like to say, "yes, please!" to this idea. I currently use Smart List to Go (the descendant of ThinkDB) on my Palm TX. The TX is dying, and I've been shopping for a replacement. HanDBase exists for the iPhone, but I don't want an iPhone. So I've been focused on WinMo - not by choice as much as by necessity.
And android option would be very welcome around my computers.

Exactly and we're talking about creating an app that would enable manipulation of an sqlite database. Essentially all that would be needed would be to create a ui framework wrapper for the existing api in android. Not the least monumental task I've heard of an individual taking on but not the most either.
The versions of pocket office that I've seen for android do not currently support Access databases as far as I'm aware. If I'm wrong could you post a link and save everyone some trouble?
aaaaaaaaaaaaaaaaaaa

Jackcess library is now patched to support android (will be in 1.2.2 release). Also seems to support 2000, 2003 and 2007 formats now.
Works great for me.
View jackcess site. Couldn't find anything on support for android. I'm using htc desire and would really like to find program to view ms access file. Can you tell me how you do it?
As I remember reading worked as on PC, while writing had some problems.
This forum prevents me from linking directly, but if you click tracker/patches on Jackcess project, check Android Compatibility Fix - ID: 3101578
The changes are in trunk and will be in the 1.2.2 release. I've added some
notes which will eventually make it to the FAQ page on the website
detailing the compatibility steps:
- Set the system property "com.healthmarketscience.jackcess.broken
Nio=true"
- Set the system property "com.healthmarketscience.jackcess.resour
cePath=res/raw/"
- Copy the *.txt, *.mdb, and *.accdb files from the
"com/healthmarketscience/jackcess/" directory in the Jackcess jar to the
"/res/raw" Android application directory.
- Before executing any Jackcess code, set the current Thread's context
classloader, e.g.
"Thread.currentThread().setContextClassLoader(Database.class.getClassLoader())".

Until this version (1.2.2) is released you need to build lib yourself.
You also need commons-lang and commons-logging from apache commons.
Before you use Jackcess in Android code, you set
Thread.currentThread().setContextClassLoader(
getClass().getClassLoader());
System.setProperty(
"com.healthmarketscience.jackcess.brokenNio",
"true");
System.setProperty(
"com.healthmarketscience.jackcess.resourcePath",
"res/raw/");
Click to expand...
Click to collapse
and copy those resource files to res/raw
Then you can work as on PC, for example open /sdcard/yourprogram/file.mdb
Jackcess has no GUI, it's a library to read/write access files.
Getting an Access file into Android
I keep a lot of information on a Psion Revo, which has just turned its face to the wall and is giving up the ghost, and have always backed the information up on to my pc as an Access file. It looks easier to get this into a format acceptable to Android by converting the Access .mbx file into an Excel .xls file. This can be searched readily by Column and Values. Maybe this deals with too simple a need for most enquirers to the forum, but if it helps somebody then so much the better.
hi all i have beenlooking for something the same for some time now and just the other day i came accross this site cellica.com
the android app is free and the desktop application has a 5 day trial period or its $50 to buy it works great the only thing you can not do is create a report from the phone
i have emailed support team and they said they will be adding it on in the future.
Any Updates???
I currently build and use databases in MS Access and was wondering if there are any updates on this topic now that Tablets are in use now. Looking to get the Motorola Xoom (2nd version) in the future, but would love to be able to use a program that I would be able to access my MS Access databases while "on-the-go".
Anyone? This would be huge (I believe), since we now have tablets.
Thanks a bunch,

Access to MS Access by Android
Hi,
I'm also looking to get on-the-go access to my Access databases on my Android HTC Tattoo.
The file is on it, I just need a tool to access it in read-only / search mode, but judging from the previous comments, there doesn't seem to be an oversupply in applications.
The "convert to Excel format" may be OK for me. I want to use a 3 language Access DB (dictionary) on my phone, so I'll try the Excel solution.
It would be nice if we had an ACCESS reader though...

Panacea Database
I know XDA frowns upon excessively hawking your own products here, but I do seem to be directly answering more than one of the reply questions, it just happens that the answer is an application my company released.
The Panacea Database application can handle Access from Access 2000 to Access 2007. It has also worked so far on every Access 2010 database we've tested, and we've received no complaints in that department yet. We release updates from time to time as we improve its functionality and features, often guided in our priorities by user e-mail and market comments. Our next update will be focused on improving screen layout for a variety of Android devices - from small QVGA smartphones, to large WXGA tablets. After that we may move onto other functionality.
In the interest of fairness, I'll point out arafa1209's post. He mentions Celicca Database, which is the only other application that I know of that deals with Access databases on Android. It has features Panacea does not have (yet) - ability to work with forms, ability to create and modify databases, ability to connect to your PC etc. Like us, they also send out updates improving their app regularly. So you can compare the apps, and use which one fits your needs better (or use both). If anyone knows of any others they can post here as well, but these are the only two I know of currently.
Just tried Panacea. Although it is more basic and annoyingly doesn't remember the last files you'be opened necessitating finding the file each time you open the app I prefer it for the simple reason you don't have to convert the Access database to another format.

If you update the app, this should be fixed, the last version should have this feature.
Got the update last week. Certainly goes a long way to making it more user-friendly. Keep up the great work!
Since the last update it seems to be broken. Although it remembers the last database I cannot open a table within any database.
Edit: It appears the file was corrupted. Loaded a new file and all working again.
Any news in this topic.
I tried panacea Database, works fine. But not very effective. Searching data is a must for me however I didnt manage to find a search option. When I search for tables, it cant even locate the tables by names.

XML database or Sqlite?

Hi,
I'm trying to create a small DB, at first i thought about using Sqlite, but since my Xposed model doesn't always have context, it seems impossible.
So i thought using XML file (eventually, my DB contains only one table, each row has 2 values). but it seems there' s no good way to manage the XML file (i need to read & write every once in a while)...
What is the best practice?
Thanks,
I don't think there's a "best practice" – you'll just need to see what you want and what's best suited for your use case.
You could try getting a context using AndroidAppHelper.currentApplication().

Suggestions for app - New Android Studio user

Hello everybody, happy to have found this forum.
I am a student and have studied 3 years Java in highschool (pretty good level) and studying for about 2 C/C++ at University, am good with PHP and databases and I know some CMS pretty well. So intermediate programming skills, hoping to improve them. I'm from Italy so excuse my bad grammar
I want to create this app for some friends of mine and I want it to be connected to a database and that database will be displayed online on a website. Basic data categorized and if possible displayed differently for different zones. So say you're from Japan and access a category from the website: firstly it asks for location access and then displays to you the "nearest" data available (if you'd want you could access data from other locations). This should have minimum costs, talking website/database.
So what I am asking, how hard this can be? I have never created a project in Android Studio, just worked with Netbeans ,CodeBlocks and Eclipse.
Is there a way to quickly learn how to save the data from an app to a database ? The other way I guess I'm able to do it.
If any of you is so kindhearted to help me find some good tutorials.
Thanks.
It depends on your skill, based on your skill set it will be easy for you.
All you need is create an API for your app so it can exchange data to your web server. You can use a PHP Framework for your API to make your life easy.
On Android part you can use GSON for converting JSON data to Java Object and vice versa.

I guess it can be created and to save your time try to build it using a mobile app builder then connecting it to other source would be easier
