Android :: Package Naming / Renaming?
Oct 21, 2009
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?

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 have modified a sample app, and it works fine. When I rename the package though, it force closes. I have modified the package name in all the .Java files, as well as the manifest, in addition to the physical directory structure. I've even tried to create a project from scratch and copy the relevant code in. Any ideas what could be causing this? Am I missing something?

i work on custom Application Manager and try to get the disk usage of installed package. So PackageManager.getpackageSizeInfo was removed from SDK on 0.9->1.0 update android.content.pm. PackageStats(String pkgName)(cacheSize, codeSize, dataSize) returns always "0" Size of phys. file (java.io.File) in "/data/app" seems wrong/not completely. Has anybody any solution to get the total disc space used by an installed package?

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 notice that there's been a bit of controversy in the last couple of days about off-topic posting on this list. As the list home page says, it is intended to be a place to "Discuss developing Android applications using the Android framework". While I find the talk about the Market and wider issues very interesting, I do think it would be better placed on the -discuss list, so that this list can be more focussed on technical issues to do with developing using the SDK.
I wonder if the reason why this list attracts a lot of off-topic stuff is the name? I suspect many people don't see the description and just interpret "android-developers" to be for discussion of issues affecting developers. Perhaps if it was named "android-sdk" (to match the new android-ndk list), that would improve things?

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 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'm attempting to override an Android View class to tweak the functionality just slightly. But I need to modify a field that does not have a setter method. I've placed the subclass in a package called android.widget. Why can't I access any of the package-private member fields? I notice that the compiler says they "cannot be resolved," rather than not being accessible. Does this have something to do with how Android.jar is built?

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.

I ran into a problem of slow builds and thought I'd share the solution. I'm porting an iPhone app to Android, and as soon as I added the images to the project (400+ pngs), build time went from about 5 seconds to about 40 seconds. This is on a new machine, quad core i7, 8GB ram. The resource processor (aapt) was to blame. Every time I made a change to a layout xml file and hit save - bam, wait 40 seconds. After running aapt in verbose mode, it was obvious what was happening - aapt does png optimization every single time. Optimization is slow, and aapt only used one core. So it makes sense to turn this optimization off. Just run optipng once, no need to optimize every build or every time I save a layout xml file.
So how do you turn png optimization off? You can't. There is no Eclipse setting, no command line option for aapt. Digging around the aapt source, I noticed something funny though - it only optimizes images in the "drawable" folders that end in ".png". http://android.git.kernel.org/?p=platform/frameworks/base.git;a=blob;...
Solution: rename all the pngs to end in uppercase ".PNG". Then aapt simply copies the files without optimizing. My build time is back to 5 seconds!
(Caveat: this won't work for nine-patch files - they still need to end in lowercase ".9.png".)

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.

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?

I SHOULD be receiving my Incredible from VZW sometime soon and I have a quick question regarding apps. Can you rename some apps such as the Handcent SMS app or Gmail app? Is there an option to change it so it can just say "SMS" for the Handcent and "Email" for the Gmail app?

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?

Did a search first. Is there any way to name an email attachment? Whenever my wife emails me a picture of our dogs (no kids so these are our kids) it always comes through as "photo" so when I download it saves as that. Now if I don't go back into the picture viewer and rename it the next time i try to save a photo attachment it tries to overwrite the last one as its comes in as "photo". Is there any easier way of renaming these attachment without having to go into picture viewer and renaming the last one first? Basically I'm want to do a "save as"

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"?
