Android :: Java Package Convention
Sep 24, 2010
I'm developing an Android project which currently has 4 packages:
com.myapp.app.activities
com.myapp.app.db
com.myapp.app.ws
com.myapp.app.utils
Would I be able to create an additional package which is just com.myapp.app. Eclipse isn't letting me create this package. It tells me a package with this name already exists. If I start a new project and create a package called "com.testing.app" and then create a new package called "com.testing.app.activities" afterward, it works fine.
For Android developers: What I'm wanting to do is extend the Application class and have it in a separate package. Suppose com.myapp.app can't be used, what's a good name for this new package?

I am writing an app that has a consistent code base, but has different resources that make it a new "app". My ant script copies AndroidManifest.xml, res and assets dirs for a particular app prior to kicking off the build. This approach works great if all the apps have the same application package name. However, I want to be able to install more than one app from this common code base, so I must change the application package name. If I change the package names in each AndroidManifest.xml, then R.java gets generated with the new package name. This causes all my references to the resources constants in my common code base to throw an error. It would be great if I could specify the package name I want aapt to use when generating R.java. Does anyone know if this is possible?

Apt while generating the resources, is it possible to provide a different package name for the generated R.java class. Currently it seems to use the same package name as the one in manfifest defination of AndroidManifest.xml <manifest xmlns:android="http://schemas.android.com/apk/res/android"package="com.tejasoft.dialer.mobile.android"> Also, is there a way to give custom class name instead of default R name say Resources.

Is it possible to instruct Eclipse and Ant to have a R.java file generated in the package com.example whilst the package declared in an AndroidManifest.xml file is com.example.d?

The only available reproducible example I can find to share with the board is the Android sample code NotePad, which is loaded into the IDE's Package Explorer as 'NotesList'. I want to know why, in the package's NoteEditor.java, LinedEditText (extended from EditText) can't be renamed? In other words why can't I rewrite this extended class as, say, "Lined_EditText" in the two lines where the word exists, in its class name and its constructor? They are the only two locations, as far as I can determine, where the words exist in the entire package.

I thought might be cool and am looking to see if there would be any interest and if so some feedback. Every year there's always massive conventions in the electronics industry as well as every other industry involving big players. However, there's never been anything specifically involving people just getting together that are enthusiasts of the same thing. I know there are car clubs that do this for example but not phone enthusiasts. So, I was thinking what about something for Android enthusiasts. This doesn't mean specifically Hero owners but any Android user's across the board. Call me a dork but it would be neat to meet some of the people I've talked to on these forums in person just to hang out for a while. Maybe there would even be a possibility of getting some industry interest from the big boys such as if Sprint, HTC, Google wanted to have reps there just to talk and answer questions.
It doesn't necessarily have to be a convention so to speak but an organized way of getting together to share your interests with other people like you do on here, but instead in person for a day. I unfortunately don't have the means to actually rent out a place to make this happen nor do I have the connections to get any major players interested but that doesn't matter. It could start small and get bigger if there's enough or any interest.
I definitely don't have all the answers on this nor know exactly how it could happen which is why I'm turning to you guys. Maybe there are some of you that would like the idea and then it would be a matter of figuring out where geographically it would happen and when. If anyone is truly interested I would be happy to discuss ideas further via email or phone just post on here first.

I am releasing two versions of an app--free and paid. The differences between the two are few, and I would like to release both using the same codebase (maybe a different constant defined for the other build?). Has anyone done this? Can someone point me in the right direction?

I have transferred videos on to the phone, but the names are not there, just numbered? Is there a convention to follow to make sure I watch the correct video?

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?

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'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?

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'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; ....
}

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 have installed the new SDK 1.6r1 on Windows and I realise that 1.6 does not included the older APIs so ran the android.bat tool to download them. The "available packages" only offer me SDK Platform Android 1.1 API 2; I was also hoping to download 1.0 API 1 as I am developing an application that only needs very basic functionality and I would like to be compatible with as many devices as possible.

Just wanted to know, if we participate in ADC2 will we be required to use a different package name (to the ADC one) for our app *after* the competition is over? Reason for this is that I'm wondering whether I should assign a separate package name now for ADC and keep my standard one for later.

I'm looking for a way to get the certificates from a package that are used to sign it. Using the PackageInfo class it is possible to get the signatures. But what can I do with signatures if I don't get the public keys to verify these.
The next question I have where does the PackageInstaller verify the signed APK file? The PackageParser class loads the APK file into a JarFile object but does this automatically verify the signature?

does anyone know how you can find the package name for a particular app already installed on your handset? They usually go like: com.example.prototype(Where the folder prototype cotains the runnable files)Trying to use the intent function to launch an app within an app.Was told putting this code in the onclicklistener method for the button would allow this, yet to test it successfully. I reckon it works, just need to figure out package name of the app I wanna launch.Intent i = new Intent(Intent.ACTION_MAIN);i.addCategory( Intent.CATEGORY_LAUNCHER); i.setPackage("com.otherapp.package"); startActivity(i);Want to press a button, to launch the "com.otherapp.package"

If i create a service and in it use the method context.getPackageName() or context.getPackageCodePath(). If i then compile that service into a .jar file and someone else includes it in their app will those methods return the original package of the service or that package that they have been included in?
