Android :: Naming ID In Phone Applications
Nov 24, 2010
If you are developing Android application, you will encounter such a id naming in xml files of view and layouts :
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="@+id/new_game"
android:icon="@drawable/ic_new_game"
android:title="@string/new_game" />
<item android:id="@+id/quit"
android:icon="@drawable/ic_quit"
android:title="@string/quit" />
</menu>
and I am really wondering why such naming is applied to ids. It is because of Linux? What kinda meaning this naming --@+id/...--has? When I am looking at android:icon attribute I can interpret that it means ic_new_game is located under drawable folder and @ means "located at" or I just assume that. But naming id attributes are kinda different because they also have + sign. Can somebody help me understand this convention?

I was wondering if there is an app that allows you to name your phone. For example lets say i named my Droid. Optimus Prime And then i could use voice protocol after saying my phone's name For example Optimus Prime please text autobots (contact group), "Autobots Transform and roll out!" After saying its name the phone would automatically know that Autobots is a contact group and that the message i want texted is "Autobots Assemble!" Is there an app like this already? If there isn't it would be a great idea for one.

It looks like the naming style for android attributes varies between underscore and camel case. Does the variation mean anything, or is it arbitrary? edit: examples would be layout_width and columnWidth.

Try as I might, I can't find a way to give my Milestone a name on WiFi. My employer are being funny about adding a device that is unnamed, but I can't see where to do it.

Are they that lazy that they cant even give any of there new phones a real name. they just take the name of an older phone and just add the letters "HD" or "Z" to it. and the Desire HD and Z dont even resemble the original Desire is any way at all. also same thing with the Mytouch HD, wich is just a Mytouch 3G slide with out a keyboard. speaking of the Mytouch 3G slide that is another crappy named phone, why couldnt it have been called just the Mytouch Slide instead? did they really need to have "3G" in the title when 99.9 percent of all other android phones have 3G support? and now the Evo 4G and Epic 4G, are they going to have to make EVERY single upcoming 4G android phone have "4G" in the name too? and another thing that pisses me off is the "DROID" name. what idiot at verizon decided it would be a good idea to just rename all of there major androids to have the word Droid in front of it? why couldnt the Droid Incredible and the Droid Eris just be called the HTC Incredible and Eris just like they were originally planned to? and HTC did not even make the original "Droid" phone, so HTC shouldnt even be naming there phone Droid in the first place, ONLY motorola should. what is next? are they going to release another phone for verizon and call it the "HTC DROID Incredible HD"?

I am about to start developing an Android application and had a question if in Java there self naming. For instance say I had a variable named dog that held the value of scruffy. Could I then create a variable named scruffy from that variable. In PHP it would be $$dog. That would make a variable with the name scruffy.

Is there a publicly available document explaining the naming conventions followed in the Android SDK?

I am trying to do an update to an app that was released under 1.0 about a year ago. When it was released, I used the package naming convention: "com.android.myApp". At the time, I thought this was the correct naming convention. In retrospect, this is not the case. The AndroidMarket does not accept new apps with "com.android" package names, so I am assuming the way I did it is frowned upon/disallowed. So my question is two-fold. #1: What is a correct method for selecting package names? I have started using a convention "com.myAppClass.appname". Where "myAppClass" is a arbitrary name that applies to a group of related apps and "appname" is the specific application (e.g. "com.mycategory.appDemo" and "com.mycategory.appFull"). Is this right? #2: What do I do about the app already released as a "com.android" package? My assumption is to recreate it using the above convention. What will the effect be on users who want to upgrade the application through the market or will the market even accept an upgrade version using a different package name?

I don't see an option for naming a folder that you have created on your desktop. You can do this on blackberry.

Here http://source.android.com/submit-patches/code-style-guide#shortmethods it is stated that :
"Field Names
* Non-public, non-static field names start with m.
* Static field names start with s.
* Other fields start with a lower case letter.
* Public static final fields (constants) are ALL_CAPS_WITH_UNDERSCORES.
also states that : "The rules below are not guidelines or recommendations, but strict rules. You may not disregard the rules we list below except as approved on a need-to-use basis." I don't like the "m" convention before private or package fields in a class... I really find this uninspired. I mean, if we try to apply good designs, the low coupling of the classes implies having few public fields. actually, in my programs I usually have no public fields, even when I need some I use getters and seters. so, why should I be forced to have almost all my fields in the program with an "m" in front of them? wouldn't be easier to have the few public fields, if there are any, with some "g" in front or something? or just use setters and geters as beans suggest? this really makes my code harder to read. also, following these guidelines, local temp variables used in the methods have no restriction so they could easily be mistaken for public global fields (also without restriction). this also I find to be wrong, as it is a probable source of mistakes. I understand to have a way of differentiating from fields, but private/protected member fields are the most used in an application, they shouldn't be less "readable". what do you think? should I follow the guidelines?

I go back and forth about how to name activity classes.Activity seems to imply a verb, like EditContact, for example.But that seems more like what one would call the Intent that triggers EditContact.Should the activity be named ContactEditor instead?

Can anyone help with album covers? I have one album that shows up with its cover in the default music player. I assume that is because it is included in one of the tags information, I added covers to other albums tag info using windows media player and the advanced tagging option (method found in other forum for other lg phone) but the covers still don't show up when I put the albums back on my phone. Does anyone know which tag the music player is reading? There is also a folder (albumthumbs) that showed up on my sd card once I copied the album thats artwork does work to my phone, and in it is a file without an extension (this is obviously the cover for the one working album). Can I add jpgs to that folder or something and how does the album thumb naming convention work?

When adding a new folder, it simply states: "Folder" Is it possible to give a folder a name? Modify the name of a folder? Re-name the folder? Once items are dragged into folders, can they be taken out? Dragged out? Deleted while in the folder? Seems I have to delete the entire folder and start over.

I'm currently programming an application for the Android. Now what I found out is that you cannot place resource objects, say, an image in the drawable folder and name it like "myTestImage.jpg". This will give you a compiler error since camel case syntax is not allowed, so you'd have to rename it like "my_test_image.jpg".
But what about ids you define in the XML file. Say you have the following definition
<TextView android:id="@+id/myTextViewFirstname"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Firstname" />
This is a valid definition, compiles and works just fine on my Android emulator although - as you see - I'm specifying the id in camel case syntax. Now, the Android samples always use lower case and underscore. Is this just a naming convention to use lower case with underscore for the id's or may it cause problems on the real device?

If I purchase an app with my current phone, and then I upgrade to a different phone in a few months, is there a way to take the apps with me? I have searched and can't find anything definitive. The ideal thing is if Google is storing my application history with my Google account somewhere, but I don't see where it would be.

I've been developing applications for a long time now, but now I want to jump into Phone applications development. There are four main candidates:
Nokia's Symbian
Apple's iPhone
Google's Android
Microsoft Windows Mobile Phone
considering documentation, market, samples and availabilty of emulators, I'm not a millionaire so I can't buy it unless I know it would mean profits!
I don't have much preferences as for languages, but to stay within C# would be nice, however I've been thru Assembler for a long time, so it's hard to scare me.

Ok here's my problem. I'm very new to the AndroidSDK. I've ran sdparted to convert my ext3 to ext4 and just tonight I learned how to open the emulator.I used the Android development site to learn how to do all this. I ran this: emulator -avd my_android1.6 -t 2 The emulator opened up but, it looks nothing like my phone nor does it have any of the apps that my Magic 32B has. This is my question. I'd like to be able to run an application that is currently installed on my phone on my computer to enter in a bunch of data into that application to use on my phone. It's much easier to type everything out on my computer than using the keyboard on my phone. Is this possible to do with the emulator and if I can how? I'm rooted and using Cyanogen 4.2.5.

I have a Droid X running 2.2. I'm trying to understand the advantages of storing apps on the SD Card vs Phone storage. Since the Droid X comes with 8GB of phone storage, I've got lots of room there.What would be some reasoning behind moving apps to the SD card? I see lots of people get excited when a favorite app adds SD card support, but why exactly? Maybe it's more of an advantage for phones with less phone storage? Also, how come in manage applications, it says that the app takes up way less space when it's on the SD Card? For example, I just installed Angry Birds and it put itself on the SD Card when it installed. It showed 1.83MB in size. When I moved it to the SD Card, it showed 14.06MB.

I am planning to purchase a DroidX on launch day and am switching from a BB Storm2. There are a few apps that I love on my Storm2 that I would like to have on the new phone. Wondering if you guys (and gals) can point me towards similar apps for the Android platform. 1. BerryBuzz - Customizes LED light for different notifications (I.E. can set light to Orange for SMS, Disco light for missed calls, etc.) 2. BerryWeather - Awesome weather app 3. Later Dude - Can set a reminder (calendar, task, call, e-mail, etc.) based on an incoming message/phone call 4. Pocket Informant - Great PIM app.

I am trying to figure out some way to determine the current background on a phone and then set that background as my own in my application to create a seamless transition between my application and the phone. However I haven't been able to find any functions for this at Androids SDK site. Setting android:theme="@style/Theme.NoBackground" inside my Manifest almost does what I want, but it still has the icons in the background.

In my haste and excitement to try out my phone I downloaded loads of apps from Android Market and didn't really pay any attention to the warning screen that shows you which parts of your phone the app needs access to. Is there a way to check up on this after the app has been installed? What I would like to be able to do is go through each application and see what parts of the phone is needs access to and uninstall it if I feel that it shouldn't need access to various items.
