Android :: Application For Different Versions And Resolutions / How To Create Emulator?

Oct 23, 2010

I am in middle of learning application development. I have created an application in 2.2 and tested that in my HTC Nexus One device. I looks like fine. My client testing same application setup in his device (Droid2). I don't have that device to test.

He said there are some font sizes are vary and button alignments are missing. When I testing in my device everything looks fine. So, I need to test my application in Simulator which resembles like Droid2 device. Can anyone tell me how to create emulator and setup like Droid2. And also, is there any need to adjust my code or anything in manifest file.

Android : Create FindViewById Parm Dynamically Or Programmatically At Runtime

Sep 27, 2010

I have an xml layout that will display a grid made up of textviews within tablerows.  The textview names are cell00, cell01, etc.  At runtime, my program will determine which cell needs to be changed.

Is there a way get format a name so that it can be passed to the findViewById method at runtime?  For example, if cell00 is needed, how can I generate the parm in this code?

TextView currcell = (TextView) findViewById(R.id.cell00)

Something like "cell"+00 doesn't compile because the findViewById method doesn't accept a String type.  I don't want have every textview name in the grid hardcoded in the program - there must be a better way.

Android :: FindViewByID Returns Null - Works Different Than Activity.findViewById

Jul 16, 2010

first of all: yes, I read all the other threads on this topic. And not only those from this site... (you see, i'm a little frustrated) Most of them come with the advice to use "android:id" instead of just "id" in the xml file. I did. From others, i learned, that View.findViewById works different than Activity.findViewById. I handled that, too.

in my location_layout.xml i use

<FrameLayout .... >
<some.package.MyCustomView ... />

<LinearLayout ... >
<TextView ...
android:id="@+id/txtLat" />.................

Android :: Possible To Create A Small App-plugin-framework

Jun 21, 2010

With iPhone, creating your own AppFramework is made impossible by the fact that Apple won't let your apps download binaries. One can understand this as it would potentially mean that people could set up their own App Stores (however unlikely it may sound).Is there anyone who knows of any such restrictions for Android?

Android :: Need To Obfuscate Code For Small Scale Paid Application

Nov 3, 2010

I'm nearing the end of a small project to develop an android app. As a first time developer, and a one-man band, I am anticipating selling it at a low price point. I have followed some of the discussions on the Android blog and elsewhere about licensing and obfuscation, and I am in two minds. Part of me thinks that I have spent a long time on the development, so why should I make it easy for people to pirate the app? The other part thinks that it could be fairly time consuming to implement licensing and obfuscation, stop people using the app from non-google supported countries and wondering how much of an issue it is anyway for a small app.

However, if you google even a small app and add .apk at the end the number of "warez" downloads is fairly shocking if it's true. Just wondering whether anyone has any opinions either way, about the impact of piracy on a small developer. I'm not expecting to make my fortune with this app, and would aim for I guess 1000 downloads or so. I may even release an ad-supported version some way down the line depending on how sales held up, which would solve most of the problem I guess.

Android :: Application Optimized For High DPI Screen But Supporting Only Small / Medium

Aug 18, 2010

I'm building a game with graphic assets in hdpi resolutions (hence I put the files in drawable-hdpi directory). I don't want to have a corresponding mdpi resolution of the images, and I will code everything in 240-dpi based pixel coordinates.

Is it possible to still allow mdpi and ldpi devices to run the application, by automatically scaling the graphics from the hdpi version? Optimize for high-dpi devices only but still support (small- and) medium-dpi screens.

Android :: Application In Emulator Without Restarting Emulator In Eclipse?

Apr 8, 2009

Is there a way to reload an Android application in the emulator without closing the emulator, saving any code changes, and running the emulator again? If I make even a simple change to the layout, it takes about 30 seconds by time I run it in Eclipse and Android "boots", and I can unlock the emulator to run the application. Is there any way to shorten this time when making changes, or is it something I just have to deal with?

Applications :: Any Simple Application For Reminding Missed Event?

Dec 22, 2009

Just switched over to the Moment after being a BB and Iphone user for the past few years. Love the phone. I have been searching for a program that will do something very simple. Just randomly glow on/off the home menu or back button led when I miss a call/sms/receive email etc. when the phone is locked and screen is off.

I work in my office and prefer having my phone turned to off while working with the screen off. So right now, I have to check my phone every so often and it's kind of annoying. I tried the program "Missed reminder" doesn't work at all on my Moment. Heard of a program "Missed Call" cut couldn't find it in the market. I think a lot of Blackberry users would instantly pay $10 for a program that was reliable with customized Alerts through the LED's!

Android :: A Simple Bill Reminder Application That Isn't Intensive

Aug 26, 2010

I am new to Android.. and smartphones for that matter. I am looking for a very simple app that has bill reminders. I do not really want it to have access to the network, therefore using data constantly.
I guess I just want to be able to put in my bills and have them show up on a screen so I can see what is due, and paid. A pop up reminder would be okay.
I downloaded Astrid, but it looks like that one uses network access constantly. I prefer this to not be the case. Does an app of this sort that does not access the network whenever it wants even exist?

Android :: Simple Client Application To Store Clients Information

Oct 12, 2010

I just purchased a Samsung Intercept through Virgin Mobile and am hoping I can find a simple application to store my clients information using it.

I am a Hair Colorist and I have been using a Sony Clie in the past to keep my client info up-to-date, but it finally died. I am hoping my new phone can keep track for me now.

Here is what I need the app to do.

1) Clients Name (so I can easily search for client)
2) Phone Number (so I can call them)
3) Address (not mandatory, but would probably be good)
4) Client's Hair Color Formula (text area where I can write down their color formula)
5) Date of last appointment (and maybe their upcoming appointment)

Does anyone know if there is something out there like this already? It seems like it should be a basic app, but I am BRAND NEW at this, so I have no idea .

Android : Want To Create - Establish Ad Hoc Network On Emulator?

Sep 23, 2010

I am developing an application for android based cell phone from emulator. The application i am developing requires ad hoc network. I do not own the phone or can't get it from anywhere else. So I want to create and establish ad hoc network in that emulator only. I am using standard ADK 2.2. I read somewhere that the information and settings of networks are read through a file called tiwlan.ini. Is this file available even for emulator? If it is, where is it located inside it? If its not, can i copy the file available on Internet and put it somewhere inside my emulator and change system path to read network information to that file's path? If even that is not possible, is there any solution available by which I can establish ad hoc network on emulator?

- Why wifi not supported by the emulator? Will it be?

setContentView(R.layout.main);
