Android :: How To Distribute Reusable Code In Package?
May 13, 2010
I have developed some reusable android component which is basically a class . This class has some resource dependencies e.g. some png drawables, some xml layouts etc. So this class referenced the auto-generated R file.I would like to distribute this code in a single package like jar file to other developers for use in their applications.I have read that the only possible solution is to distribute code together with all my resources, which others have to copy to their "res" folder (source).So I created a jar file having the class file (say MyClass which is in the package com.xyz.android.app) and resources and tried to use this in my new application.So I added the jar file to my new applications build path using add external jars option in eclipse and copied all the resources to my new application's res folder. (The activity class say MainActivity of my new application is in com.abc.myapplication package, just for the case if it may helpful)
But when I run this new application there is java.lang.ClassCastException in the MyClass class. I tried to debug the application and then I found that in the MyClass class, there is "R cannot be resolved" problem. Then I changed MainActivity's package to com.xyz.android.app (which is not the way, other developers will be happy to do), But again the same problem.But When I just copy the source java file such that both Main Activity.java and MyClass.java are in com.xyz.android.app package then application runs fine.So if I need to distribute such that other users need not to bother these package naming things,how can I accomplish this?

I have done some cusomtizations on general user interface behavior. I would put those features into my applications. Therefore, I package my source code as a jar and add this external library to my applications.
As my cusomtization include some inflation of xml files, I put those resource in my package. However, when I finished compiled my application and ran it, it reports error. It seems cannot locate the xml file in the jar. (My debugger stop while inflate the xml file). Do I miss any step to use my jar file?

I'll preface this with, I've just started learning Android so be gentle.
I come from an ASP.NET / Silverlight background so I was looking for something along the lines of controls.
I want to reuse a layout (a ListView item template) in other layouts.
Such that in my other layouts I can just add <myListItem /> to show it.
Is this, or anything like it possible? or are there better ways?

I am creating an Android library that does stuff like http requests, etc, that uses android.jar objects. There will be no manifest or resources, etc, however. What is the best practice regarding the JUnit library to use in this library? DO I use standard JUnit, or the one included in android.jar?

I have a $300 iPhone app that I might like to port to Android.It is for a very narrow set of users, so no matter how low I make the price, I will never sell very many.But for those few users, it is definitely worth it, as evidenced by my iPhone sales.So the $300 price point is necessary. However I have heard that the Google Android Market puts a limit of $200 on apps.I have also heard that it is possible to distribute apps independently of the Market, in which case I suppose I could charge as much as I wanted. But then I would have to devise my own licensing scheme.Are these assumptions right?

I am developing an Android application for a customer. I want to be able to provide them (no one else) incremental updates but I am not clear what the procedure should be.I don't want them to have to install development tools or root their phone. These are non technical folks who would have no idea how to accomplish root a phone or use a command line interface.When I develop iPhone applications for them this was easy. They just give me the device UDID and I send them a binary that can be drag and dropped into iTunes.How is this done on Android. I have tried loading the application from a web server but the devices says it is not allowed to be loaded because of security reasons. In setting->Applications there is no menu option to "Allow Unknown sources".

I have an early version of my app that I want some testers to take a look at. But I am not ready to put it on Market. How do I distribute it to my testers and how do they install it on their phones. One of the beta testers has a Asus eeePC with Android 2.0 installed and I would like him to try it too.

Does the android market support distribution of content packages? Is there any way a dependency structure can be created so that to obtain a content package for the app depends on the app to be installed as well?

We are planning on this strategy to distribute our application to clients. We would like to get your your thoughts, if you have done something similar, in terms of whether we are missing something. We have tested this approach and it works.We want to distribute our application to our clients without putting it on the market as we do not want every one to download it. We want our clients to be able to easily get future upgrades to the application. Here is how we are planning to do this:
1. export the apk file using the Eclipse wizard.
2. put this apk file on a website. The user will be able to go to this website on the browser on the phone and install the 1st version of the app.
3. next versions of the app will have an incremented android:versionCode, and android:versionName in the manifest. A button in the settings will point to a link which will have the next version of the app. So to upgrade the user will click on this settings button and download the next version and click on the apk file to replace the old version.All subsequent versions of the app will be signed by the same certificate using the export wizard in Eclipse

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 have a linear layout (oriented horizontally) that contains 3 buttons. I want the 3 buttons to have a fixed width and be evenly distributed across the width of the linear layout.I can manage this by setting the gravity of the linear layout to center and then adjusting the padding of the buttons, but this works for a fixed width and won't work for changing devices or orientations.
<Linear Layout android:id="@+id/LinearLayout01"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:gravity="center">
Button
android:id="@+id/btnOne"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:width="120dip"></Button><Button
android:id="@+id/btnTwo"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:width="120dip"></Button>Button
android:id="@+id/btnThree"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:width="120dip"></Button></Linear Layout>

I was wondering how everyone re-uses android layouts and components? Do you do the old copy/paste the existing code into the project, or is there a way to include the layouts and components into a jar file for re-use? For example if I have a list view, maybe I have another view that I am using for each list item in the listview, it could have an icon, and maybe a header row, and then a row with more details. While it is not hard to create this, it would be nice to be able to create this once generically and re-use it in different projects.

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?

this question is now obsolete, as Android Market includes much more countries and such services as PayPal Mobile Payments Library are available.I'd like to sell my Android application, but I live in Poland and in my country* Android Market supports only free apps (we cannot sell and we cannot buy too).What is the best way to sell application in such situation? I can accept PayPal money transfers, but I don't know how to distribute APK package without exposing it to getting pirated. Did someone tried it already and succeeded? you may be surprised, paid apps are supported only in 12 countries worldwide.

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"

I am trying to put an XML file containing over 1,000 different fish into my app so that I can read this file, create an Array and attach that to the AutoCompleteTextView. I first tried to create a string-array in a resource file but apparently the array was to large and would never actually load anything after a certain number of values. So want I want to do is add that XML file to a place in my app that I can access it and read from it. Whenever I try to bring the XML file in I get all these errors in Eclipse. So how do I add this file and how do I reference it later in order to access it? I could just store it online and access it that way but I think it is a little bit of a waste to have to access the net for that if I can instead just add it to my package setup someplace.

I've written an Android app wich various abstract classes that perform useful functions. These functions could be leveraged in other apps. I want to share a class module with another programmer, but I don't want to share the source code. I would like to share a .class file but I'm not sure how to do the following:
Compile an Android .java file into .class What does the receiver of the .class file have to do to use that .class in their project? (using Eclipse environment)

I need to use the transform package (transformer, transformfactory, etc.) so that I can convert an xml node to a new document. However, when I try to import the package, it says that it cannot be resolved. Are you not allowed to use this package on Android?
