Android :: Java Self Naming?

Apr 5, 2010

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.

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?

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?

Android :: Private Fields Naming Guidelines

Jan 25, 2010

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?

Android :: Naming Phone - Natural Voice Protocol

Dec 21, 2009

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.

LG Eve : How Does Album Thumb Naming Convention Work?

Jan 6, 2010

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.

HTC Desire HD :: Phone Stuck At Naming Phones Rant

Sep 15, 2010

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"?

Android :: Android Id Naming Convention - Lower Case With Underscore Vs Camel

Dec 2, 2009

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?

Feb 11, 2009

I'm having some problems porting a Java application to work in Android platform. I detected an incompatibility problem between java sun and Adroid sdk in java.lang.Class. I oberved that: public Field[] getFields() Returns an array containing Field objects describing all fields which are defined. That's array is sorted as attributes are declared in the main Class in sun jdk. For example, next Class is defined as: public class Example { public boolean stop; public int atr1; public String name; ....

Android :: Android / Java - Call Function In Separate *.java File?

Aug 16, 2010

I do an import of the full package name / java file, and if I do a <classname>.<method>, SOMETIMES I can get it to access - other times I get a lot of can't use a static in a non static bunch of talk. I'll admit I'm new to Java, so what do I need to do? Call a class instance first, then call my methods? I'm rather confused by this, as I want to put all of my 'functions' into a FunctionsList.java file, and all of my main Activity (UI) into a MyActivity.java file.

For example:
<MyActivity.java>
import com.example.FunctionsList;
private class MyActivity extends Activity {
FunctionsList.function();
}


9/10 times I get that static/non-static error. If I put all of my functions into MyActivity.java, I have zero problems!

I was going through the code for Activity.java and ApplicationContext.

Both these classes define many functions of Context Interface. Take for example startActivity.java

Activity Class has its own implementation of startActivity ApplicationContext class also has an implemenetaion of startActivity.

Now there are 2 observations...

CODE:..........

Questions: 1. Who uses ApplicationContext class? 2. Does Activity class ever deal with ApplicationContext class (as given in the javadoc comments of ApplicationContext.java).

Android :: Java To C++ Bridge

Sep 18, 2010

I know there are plenty of tutorials about integrating C++ into Java, but whats about the other way around, a Bridge from Java to C++?

The reason i'm asking this is Android.

Every C++ developer who wanted to write applications for the android noticed at some point that there is no serious (mature) C++ api for android (infact, android is lacking an implementation of the STL).

The only API that is mature enough to write android applications in, is Java. So instead of writing an api from scratch, wouldn't it be possible to use the Java Classes from C++?

I know that this sounds merely like an unrealistic dream, but that way most C++ developers weren't forced to learn a new Language.
