Android :: GUI Design - Mockup Design Tool For Android Application
Nov 23, 2010
I am going to develop an Android Application but before developing it i needs to have MockUp for the Android Application,so is there any way to design MockUp/GUI Design tool for the Android Application?
I know about DroidDraw tool , but i think it is not the exact way to prepare Mockup for the android application.
I have already referred this SO Question , but overthere i just found all the tools for the I-Phone only. So please feel free to share with me if you have/found any !

I have tried DroidDraw and the Eclipse layout editor and both seem very difficult to create anything other than very simple layouts. I find myself dropping back to the XML file to be able to manipulate it.
Has anyone found any good tools to design the actual screens? I am not looking for a mock-up tool... but an actual tool to create the XML layouts.

I am about to embark on developing a mobile application for both the iPhone and the Android based phone.I have most of my gui mock ups written down on a white board and some in my head. I need to put them down on paper so I can relay my designs to others in my team.I was wondering what the best on-line gui mockup tool I could use? I have a lot of experience with Visio and I truly like it. I want a tool that would be web based so I could collaborate with others on the team. Does anyone have a suggestion for an easy gui mockup tool that I could use?

I am new to Android development and am interested in working out a design of an application. I am however, unfamiliar with the best way to handle what I want to do. I am interested in obtaining information from my band's Joomla website and placing it into an Android application. At the moment I'd like to get News articles posted and potentially other information that I create on the site. I was thinking of doing this by setting up RSS feeds for the website. Would it be better to somehow access the data directly by connecting to the database? I don't know PHP so I can't develop a webservice to access the content. Any ideas?

I have read the topic about supporting multiple screen size as well as different DPI. I am wondering which of the following way is better in supporting multiple screens:
1. Have different layout for different screen size (stretch the images)
2. Have different set of graphics for different screen (use the same layout)
3. Have different set of graphics and different set of layout for each of the screen
Which way is the easiest? And which way is the most optical way to design? Or is there another better way?

I'm kind of new to android development.I have read from many sources that findViewById() is a "costly" operation. I'm making an application that deals with 5 TextViews to provide different kinds of information (distance, duration, title, description, etc) from a database. I'm using listeners to catch touch/click events and feedbacks a handler. The main function of the handler is to received a "position" in the Cursor where the new information needs to be displayed. I mentioned earlier that findViewById() is a "costly" operation. So, I don't call this method in the handler. Doing so, it will retrieve every time the Views when user touchs/clicks some widget. Is it right to populate the Activity with private members of the Views/Layout it displays? I mean, I don't like it. I don't know why, but seems that I'm populating too much the activity. I'm aware of the android:onClick xml attribute, but in my case I also use long click listeners. So, a piece of onCreate() looks like: And all of those are private members, wihout mention the "cursor.getColumnIndex()" for each. I thought on implementing Handler.Callback and set on the Hanlder.Callback constructor implementer a View array or a View list or something, but I also need this objects later to set other listeners and setups. Is this right? I cannot think another way, as I need the reference to the object, and also the Cursor reference that the handler will move to the "position" provided and update the correspondent View. I will really appreciate either an advice or a useful link/info/doc to read in what concern in this kind of designs. What I do not like is that It looks like imperative programming filling the Activity with "global" variables.

in Android code, It is a very strange concept to define the APN type (APN_TYPE_MMS). The reason are: 1) APN only is an access pointer, it haven't any special attribute for MMS or other things. 2) Only Application care the APN name, since different APN will provide different service from operator. for example, operation may provide Email/MMS/GPS/.... service on different APN. 3) Android only define one type APN_TYPE_MMS, this will limit other top application usage. Any one can answer me why Android design this way? If google have strong reason for such design, I hope add other user defined type like APN_TYPE_USER1 APN_TYPE_USER2 then top application can set his property to use its APN other than APN_TYPE_MMS

I am a developer and recently completed the implementation of my keyboard MessagEase. It's available on the Market (with its very- different features, making it quite unlike QWERTY).
This keyboard works fine as a replacement of the standard keyboard on an Android Phone. But for a An Android Tablet, it would work best if it's implemented as a floating, movable keyboard.
(the footprint of this keyboard is mostly dependable on the size of a human's finger; it remains the same even if the tablet's display is much larger than a phone's. Therefore it'll take a relatively smaller area on a tablet.)
If I use the current SDK hooks, it will have to take a significant portion of the screen, defeating the purpose.

I have a service running that grabs the users attention with a notification. What i would like to happen when the user clicks on the notification is for it to launch a dialog box. The "proper" thing to do is to launch an activity in this way, so is there a way to get an activity to launch with out filling the screen? So it looks like a dialog box?

I'm more than happy coding apps.I am, however, rubbish at icon design.I'm sure I'm not the only one for whom this is a problem and yet all android devs need to create a launcher icon.Does anyone have any good tips on knocking up simple but effective launcher icons?

if this is a silly question, am sorry about that. I was wondering if its possible to design android icons using a 3d modelling package like blender? i know i have to stick to the guidelines documented already, but was just wondering if anyone had come across or done something similar? Its that little part of the icons(launchers) being able to have a slight perspective and looking through the requirements to design icons it seems i might be a lot faster using a 3d modelling package and then following part of the icons template guide(based from my requirement though!).

I have a general Android design question around data access. I have a number of activities in my application that need to access a SQLite database. In order to wrap up all data access logic in one place I have created a DatbaseHandler class that takes care of all data access logic. This class takes care of building up where clauses, calling the database and interrogating the resulting cursor to retrieve the query results and return them to the caller. The purpose of this class is to wrap all data access code in one place so that it can be easily managed and maintained as opposed to having data access logic scattered across all activities. Each activity that needs access to the database creates an instance of this DatabaseHandler class and passes it a reference of android.content.Context. The DatabaseHandler class then uses this Context object to call an underlying content provider as follows context_i.getContentResolver().query(...).
My data access logic (cursor handling logic to be specific) is not in the activity and so I cannot manage the cursors life cycle, therefore there is likely to be memory leaks.
My questions are as follows -
How can I (if its even possible) manage the cursors life cycle from outside an Activity? Should each activity even be creating an instance of this data handler class and passing an instance of Context to it? Perhaps my design approach is wrong and I should expose these data access functions as static methods that take an instance of the calling activity as a parameter. That way I could perform managed queries and let the activity take care of managing the cursors life cycle?

I am working on developing an application that requires me to establish multiple client-server based connections. Connection can be of two types where the Android device can be a server or a client. I can have up to 6 - 8 connections. Once the connections are set-up they need to be running in the background and are not typically affected by UI actions.Since each connection can be blocking, I am wondering what is a good away to design this app. Should I have two services for handling the server and client connections? Each service could have a "connection manager" that can spawn new threads when necessary. Or does creating two services even help? I presume spawning new processed would not be good as they will be expensive. Is this correct? I would appreciate any suggestions. Also, if this use case is not typical please let me know if you need more information to make any recommendation.

I was surprised to see a couple major shortcomings in the design of MapView and MapActivity.
First, MapView requires itself to be hosted in a MapActivity. According to the documentation,
A MapView can only be constructed (or inflated) by a MapActivity<http://code.google.com/android/add-ons/google-apis/reference/com/goog...>.
> This is because it depends on threads which access the network and > filesystem in the background; these threads must be shepherded by the > lifecycle management in MapActivity<[url]...>. > Tiles are cached on the filesystem in your application's directory. The > cache is auto-managed so you don't need to do anything with it, and can > delete it at any time.
