i am working on an android project and want to arrange my java classes into folders. eg. a folder for activity and another folder for fragments etc.
Can anyone tell me what is the standard way of doing it or give me any link to a sample project ? thanks
Take a look at this link which provides the android best practices - Android best practices. This link has additional information that will be useful during android application development.

Recently my team mates has started to work on an android application, which has more than 200 screens in an application.
In this case, I face one issue that when I need to explain the code or flow of screen to the other developer it would too much difficult. So I have to google to find the solution.
I am not much aware of the solution for android. In javascript, I have used jsDoc or swagger for API documentation, which offered a great way.
But in android, I unable to find the solution for coding documentation and screen flow.
Do I need any design tool to explain screen flow and documentation of an android application?
Let me know if you need more details or explanation I shall update the question accordingly or improve my question.
There is no way to create an automated screen / state transition diagram. If you use the Navigation Architecture component, you can use the navigation editor which is similar to Apple's storyboards. This is helpful but often times doesn't cover everything.
In our projects we rely on tools like overflow.io to create and maintain the screen flow diagrams. We use either design files from sketch or Adobe XD or screenshots from our app. This is a very manual process.
Firstly Go to File -> Project Structure. Under the Platform Settings heading, add or select an Android Platform. Go to the Documentation Paths tab and make sure the path to your SDK's documentation folder is added there - it should be [SDK]\docs\reference, where [SDK] is the full path to your SDK installation.
If it is not found you can add it manually.
After it is completed, use Ctrl+F1 while your cursor is on the item you want to display help for.
Is it possible to create a project and add libraries such as volley, that will be used in most projects anyway and then copy this project to be used again and again as the base for all future projects?
The only issue I can see there being is with keystores but if I change all of the package names then surely this shouldn't be a problem?
You can create File Templates - explained here.
Short version: Yes. You'll need to create a new Folder iwth your desired template name in
{ANDROID_STUDIO_LOCATION}/plugins/android/lib/templates/other/, create files which contain relevant information, create a folder structure & enter your desired template files.
An example can be found on github.
Yes you can, and that should be a good practice. Android Boostrap doing something similar like it.
You can take a look at base_app_android
Here the excerpt:
Base skeleton structure to start every new project, based on the
design patters suggested by Robert C. Martin (aka Uncle Bob) on his
clean architecture.
base_app_android is the project which we use at Refineria Web to start
any new Android project. It presents a structure of 3 layers, domain,
data and presentation; this approach has been chosen with the purpose
of creating an application that conducts unit testing and also allow
the portability between platforms, mainly iOS.
Yes You can create it as a library and you can use it
I am a newbie in Android programming language and I have a question. I would really appreciate if someone guides me in this regard.
I have java source code of an Android project (no entire project). Can I build the application without other required files such as xml file for layout and ....
Regards,

First of, an android application is just an "archive" that contains a specific architecture.
As you pointed out, it is composed of a Manifest (xml) file defining the different parts of your application: Activities, Services, Permissions, etc.
There is also the resources files such as layouts, pictures and files used by the application.
Finally, there is the source code.
I recommend you take a look at online tutorials which are well detailed over the Internet, and to take a look at the Android SDK samples.
To develop Android applications, I recommend that you download the Android ADT bundle (containing both Android SDK and Eclipse IDE including Android projects management).
I am a new developer for android programming. I understand android SDK does not contain all classes from android source code. For example, AtCommandResult.class is missing (hiding) from android.bluetooth package in the SDK.
Sometimes, however, I want to use the hidden code in my app and I wonder what would be the best way to do that. One approach I can think of would be to include its corresponding source code in my project with different package name to avoid conflict with existing core. But problem with this approach would be I have to maintain the code by myself from that point. One or two classes are OK but you know where I am going.
Is there any better way other than bothering google to include the code in the SDK? Thanks in advance.
You may want to use a .AIDL file:
http://developer.android.com/guide/developing/tools/aidl.html
Those can already be used to access for example in Telephony functions.
Code example here:
http://code.google.com/p/auto-answer/source/browse/trunk/src/com/android/internal/telephony/ITelephony.aidl?r=13
I am new to Android but not to programming. I have taken C++ in school and we have been taught how to create objects, but not how to build robust programs using multiple objects. So you can see that using java to build Android apps leaves me with questions.....
thinking like an object oriented programmer, do i just shop through a list of classes until i find ones that i think would suite my app
is there a definite method of choosing the best classes for your project
do i find an app similar to the one i am trying to create and try to find what classes they used
any thoughts appreciated!!!!!!
The best way to learn (for me, at least) is by making small incremental changes to an example so I can how all the various elements of it work.
Download the examples (listed here) - but accessible from your AVD and SDK manager tool from within Eclipse (Window -> Android SDK and AVD Manager).
Start by modifying those examples. They are the best possible examples you can get for much of what you will want to do.
I'd recommend you start with Tutorials and also read about Application Fundamentals - they should get you started. Also browsing Classes is useful if you like wading through lots of technical docs (I do). Those three links are definitely worth looking at.
Well first when building Android applications you need to:
Figure out what your application will be, and how it would work.
Next you would need to find out how you will implement the android classes.
i would recommend first reading a book on Android development. One that really helped me and made me an advance developer was CommonsWare
You should really get these books. When you finish you will be well on your way.
