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(

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 :: Create Simple Paint Program With Zoom?

Aug 21, 2010

I'm new to Android and Java programming and I've manage to create a simple paint program, but how do I add a zoom feature? Right now I'm just extending the View class and using the "on Draw()" method. Do I have to use a Drawable to be able to add zooming functionality? I'm not really understanding the differences between the two. If I am way off base then please point me to a good tutorial on paint/zooming.

Simple Hello World Not Loading In Emulator?

Aug 25, 2010

I have set up Eclipse with the Android plug-in, and the Android SDK. But I can't get my simple Hello World application to run in the emulator.

I am going through this Hello World tutorial. I have Installed a Platform, Created an AVD, Created a New Android Project, and Constructed the UI, but when I hit Run (and select Android Application from the menu that pops up), the Emulator starts up. It takes a while on the "ANDROID_" screen, then shows the shimmering Android logo for a while. But then it goes to the "unlock" screen. When I slide the lock to the right, it opens the Android home screen. I try looking for my app in the applications lists, but it is nowhere to be found.

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 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?

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 :: 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?

General :: Small Application To Enable QVOD File Saves?

Sep 18, 2012

There is an application called QVOD that downloads videos to a local cache on the Android device, and for many devices it works just fine. For many devices however. If the device is running ICS, frequently the playback features stuttering audio. I have found where QVOD saves the video files, although it separates them into several pieces, making it difficult to just browse to that directory and use an alternative player, such as MXPlayer. I have found that if you cat the files together into one RMV file, you can then watch it with another application and it plays just fine. That means the audio codec built into QVOD is almost certainly the problem.

What I'd like to do is build a simple graphical app that allows you to view the videos in that folder and automatically cat the files together so you can either save them or view them in another player. Having some background in programming, I understand the process flow of this is very simple. Unfortunately, I do not know how to program in java. Ideally, it would be great if the makers of QVOD addressed the problem directly, but having spoken with them on QQ, it doesn't seem they have any interest in doing so.

I don't see this program taking more than a hundred lines or so, and would be a great contribution to the Android community.The application will SURELY get a lot of attention, because it will not only allow those with audio problems to enjoy their videos, but it will allow those that aren't having problems viewing to at least save the files and also have a CHOICE of what application to view them in.
