I'm looking to make a new type app that when the user open it for the first time it will open up a pop-up menu that contains multiple check boxes that the user can select from and will then save their selections for later use. After the user selects their choices I would like to have a monthly based calender on this same screen that the user can select a date from and based on their selection this will then take them to a separate screen showing the news for that day.
I am fairly new to android app development and this will be my first go at it. I have read several books and websites but cannot seem to find the help I need to produce the code for the above desired functions. Any and all help with this will be much appreciated.
Read these tutorials and you'll be able to create just what you need
Tutorials
Your question is very vague in fact, so I will only suggest a few points to start reading from, that I believe are important.
I think that you will answer any other questions you may have by reading through the developer documents for Android and studying the supplied examples. But don't hesitate to ask another, more specific question if you run into trouble.
tl;dr
Activities (must read!)
Dialogs (you will need these)
Data Storage (also important for the app you describe)
If you're still lost, just get some sample code from the repository and toy with it.
Good luck!

I just want to start by saying I am doing this for a friend as a general information app and I am receiving no money for doing this. He would like an app to help inform his clients of different treatments as well as adding in daily memos etc. I can create an app no problem and have only created apps for general use and for my University assignments (I will also add that this is not a university project but just more to improve my own abilities). I am hoping someone may have a suggestion for how I can allow my friend to update the apps information easily. For example, I will be creating a general app that will display information (contact information, advice, guidelines, exercises etc) most of which will need updated every so often. He has also said he would like to add a daily update (almost like a daily tip or piece of advice). What I would really like help with, is for guidance on how I can have my friend maintain the app after I have done the project. I want an easy way for him to add/remove/edit memos or information. I haven't come across anything like this so I don't know if it is possible or if it is possible but complex etc. I hope I have explained the scenario well enough. Only looking guidelines of things I can research and do on my own, I just don't know where to start looking.
I want to develop an app which I stream basic text information about sports. First of all I believe I need a server which my users connect to see my stream as soon as something new is published. But I don't have an idea about how to build something like that. I did some search on web to find lessons or answers but I wasn't able to find anything useful. If it's true that I need a server, is Java language good to code server's program? Because I only know a little bit of Java.
And I want my app to have a monthly fee. I'm completely new to programming but I guess I need a database to keep track of my user information. Do I have to build my own user membership system - which people register with their e-mails etc- for all this? Is it hard to do that? And again I don't have any source of information about this one too.
I'm lost at this point. I don't know what to search to get some answers. So I'm asking you guys. What do I need to build an app with monthly fee that streams live information? I'm not expecting a full answer here but at least I believe you guys can tell me where to look for answers. Thanks.
While I agree the question is very vague and open (we could write a thesis on the topic in question and everyone will have their own way to complete) my suggestion would be to research the following:
Java - read as much as you can about the language and ensure that you are happy with (or know where you can get access to good helpers) the syntax (you mention that you know a little about Java so that is a good start).
Android programming in general. Look up the Activity lifecycle (The Android documentation is good, read as much as you can, follow the examples and try out the tutorials! https://developer.android.com/training/basics/activity-lifecycle/index.html)
Read up on Firebase; this should make the server side a little simpler (although I have only a parsing knowledge (i.e., none) of Firebase, it looks like it will be a good start). Again walk through the examples / tutorials; do the Hello World and then pull it apart to see if you can figure out how it is holding together.
Then when you have questions (which you will, we all do!) come back and I know that you will get some great help!
Once you have a few applications under your belt (personal 'play' apps) then and only then would I consider looking at the Google Play API (https://developers.google.com/android-publisher/).
Hope this gets you on the starting grid at least! Good luck!

I'm constantly trying new apps and my phone is getting cluttered with old apps, I no longer use. So, I thought I'd develop a simple app to help me out. There are similar apps, but none does exactly what I want:
I would like to have a list of apps which I've installed in the last month, which I've used X number of times (for easy access: They may be keepers!) as well as those I've not used in Y weeks.
Is there any way to get app usage statistics with Android? I guess ActivityManager might help me to gather that statistics, but is there a way to read just when an app has been used last? Or how many times in a given period?
Any tips will be most welcome :)
You can try out my app for uninstallation of the apps you don't need : https://play.google.com/store/apps/details?id=com.lb.app_manager .
Also, if you wish to find exact usage statistics of your apps, you can use my app this way: find "settings" (the app itself) inside the list (you can perform a search query), choose to make a shortcut of it, and then choose on the dialog "Usage Statistics". This way you can perform both the operations you wanted.
I also plan on adding this feature somehow in the future, but that's what you can do for now.
Here's a screenshot (it's the first on what I show here) :
I am new in android. My app is basically is to scan the QR code to obtain product information such as the image, name, description and price and choose to add to cart and continue to do so(scan the qrcode) till user choose to end shopping and click to proceed to cart and will be shown the total prices of the items selected. User then can click either to edit the cart or proceed to the checkout. I have been searching tutorial but cannot find a complete one. Can anyone guide me through proper code how could i do this?
I do not think you will ever find a complete tutorial for the your task. However, a quick googling led me to zxing which can be used for processing barcode. I didnt go through the examples provided there, but I believe they are easy to understand.
Edit:
This is an exact duplicate of another question in SO. see
Now if that answer seems not enough for you, I think you are new to Android. Just google Android and you will find plenty of tutorials available. Start with Layouts, Activities, Intents, Bundles, Event Handling. To build what you want you would need a blend of many such small small things. Good luck
You will most probably wont find one single complete A to Z tutorial satisfying ALL of your app requirements .
But you can search for code/tutorial implementing parts of your app , like reading QR code , proceeding to next item etc . You will have to figure yourself out how it all comes together.
QR reader app on Google Play store
I'm very new to coding and have searched everywhere but havent been able to figure this one out.
Im trying to create a Lap Time Leader Board for various tracks in a video game guide. The user needs to be able to Click on the track name and then inside of the new layout "Create" a new time...that needs to allow him to imput the Car and the time it did on this track, then it needs to either sort itself or be manually sortable so that the times are in order from fastest to slowest. While i can build the layout easily i get stumped there.
How can i make it so that when the user clicks "Create New Time" the code gives him the spaces for time and car model.
How can i make sure it saves the correct info with SharedPreferences since each time will need to be saved differently (i think this has to do with the name and then ++ but i could be wrong)
How can i make it sort itself or be sortable for the user.
Can someone show me some sample code that does this? I dont know much of anything about SQL and would prefer not to use it if i can avoid it.
Im sorry this is such a noob set of questions but this after trying the notepad tutorial on AD and numerous video and book tutorials i havent found what i need to make this a reality.
You can always use a the Dialog class to create a pop up dialog to allow the user to input the information you are looking for. Sorry that you wish to not use SQL
Shared Preferences isn't such a good idea because you will have to do a lot more work to code your desired affect. A datatbase with simple Relations(tables) will suit your needs as opposed to Shared Preferences where you'd have to get creative to have the same data structure. Such as an ArrayList of BasicNameValuePairs, that could be a head ache. Database is the way to go, you can do everything you need if it's properly set up.
Sorting is quite easy in Java as you could always use the Collections class and implement the Comparable interface to compare your lap times to each other and sort them by total time. For a display such as that you would want to look into a TableLayout in Android XML. Don't worry so much about that, the Eclipse IDE will let you easily create and populate it. This would involve loading your laptimes from your database into a List and sorting them by time. It's a bit tricky but easy once you understand the Comparable interface and Collections if you need it.
If you need more insight post a comment, just wanted to share some ideas on how I would approach it.
