I am working on a temperature control app for a wireless thermostat. I really wanted a slider that has two nodes instead of one. The slider would define a temperature range. The thermostat would keep the temperature inside that range.
I found a widget I can use located here: https://android-arsenal.com/details/1/390
How do I import that widget into my project so I can use it? I have searched all over the internet looking for a guide or instructions, but cant find any. I think I may be searching for the incorrect terms. I'm new to Android development, I mostly do embedded software.

I have been looking for a way to implement dynamic stock charts into my Android app but I don't where to start. I know I'll need a library, in fact, I found two LightWeight Charts and Vaadin but I don't know if they would work. I am very new to android programming and have never actually implemented a library into any project ever. I just need some guidance.
I suggest to search "stock charts" in google image to find what kind of chart you need before you choose.
Decompose this graph into data curve, background and scale. Maybe you have to implement them separately.
Find some Android library recommend web site that has the "similar lib" function which help you to find a lot of this kind libs. As I know one: https://android-arsenal.com/
My AD: https://github.com/maxyou/SimpleWaveform. It only draw a list of data to a rectangle, and you can draw any background and scale by yourself. Surely, you need to compare a lot of libs and then choose the most suitable one.
So I have a project for school, and they have not taught us android studio in the least and I have little experience with Javascript. I have looked at countless YouTube tutorials trying to figure my way out.
The project requires me to develop an android application that communicates with an ELM327 adapter. I am allowed to use open source software. I would like to take this: https://github.com/pires/android-obd-reader
and improve the layout as well as add some additional features such as live graph plotting and live gauges.
The first thing I'd like to do is change the layout to a tabbed layout rather than the layout the app currently has. Can anyone assist me in the best possible way to begin doing this? I am reading as much as I can but seem to be making no progress.
I am in the middle of writing an android app while teaching myself java all at the same time and my project is a bit cumbersome for a first time app. NOTE:
I am not a newbie to programming, I know several languages with the exception of java and writing code for mobile devices. With this all said and done, I don't want to have to force my users to have to update the app every time there is a new image.
Is there a way, I am assuming there is, to check on startup if all the images are up to date and if not download the new ones to the drawable resource folder for use in the app?
I have searched and found ways to remotely fetch items but nothing specifically for updating app images. For example: Splash Screen Image, or background image etc.
Thanks for your time and apologize if this does not conform to stackoverflow form of asking a question.

Based on my knowledges, there is no way to do why you're asking for. Resources are static contents and there no way to modify or update them programatically.
To achieve a kind of feature that you describe, it should be through a distant server, eventually with a local cache of your images on disc, associate to a download date.
But you won't be able to use them in the exact same way that you can use drawable resources.
Also depends of what you really mean by "if images are up to date".
Hi I am designing an Android App using Android Studio for my class and one of the requirement is that the app should link two users together as "partners" so that they can receive notifications or messages from each other. I already have google sign in available but I don't know how to link two users together. Can someone point me in the right direction to get started? Thank you.
You're looking to create an app that can connect users wirelessly and then do whatever tasks you wish to do. Now I'm not going to give you the code or anything like that, but I'm going to point you in the right direction as you asked.
The Android Developers site is a good place to start: Building Apps with Connectivity
The first two categories are closely related to your type of question, and will give you the stepping stone you need to start developing an app that fits your purpose.
Anytime you have an actual issue with coding it, StackOverflow will have countless solutions I'm sure.
Does anyone have some source for connecting to a Wiibalance board using java? I have looked at Wiiboard_simple project on google, but it never seems to connect correctly. I have seen other examples in C# and javascript, but none in java.
Check out some of the libraries on the WiiBrew.org site:
Wiimote Libraries for Java
I have only been looking at this from an Android perspective, so its not entirely useful for PC-based Java.
However, for Android info, including some Android Java links, check my answer on this thread:
How to connect wii balance board with android
Basically it links to:
#Ben Mordue's answer on: Is it possible for an android device to read information from the wii controller and nunchuck?
Blues-IME project for Android - you might be able to use some of that code
WiiBrew.org pages for Wiimote & Wii Balance Board
Update:
Last night I was able to get the Balance Board correctly communicating to the Android device based on the library, and the info on the wiibrew.org site. It really is not that difficult once you get your head around working with HEX commands.
The important part is to realise that the Balance Board is treated in much the same way as a Nunchuck or Classic Controller. Since most of the libraries can access these Extensions, it should be easy to adapt them to also detect the Balance Board extension.
