Android :: Shared Code Project Across Applications In Common Library

Apr 14, 2010

I am currently moving from Xcode and iPhone development to Android with Eclipse. I want to have a shared code project so that I can store all the code to be shared across apps in one common library. However it would appear that the only android project available is for applications and not for code libs how can i achieve this?

Android :: Package My Common Code As Library

Aug 31, 2009

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?

Android :: How Can A Code In Library Project Call Code In App Project?

Oct 8, 2010

In an effort to reduce duplication, I have my app's workspace split into 3 projects:
Main (A library project, where all of the common code lives)
Free (To make the free version)
Paid (To make the paid version)
Behavior in the free version and the paid version must differ sometimes. How can I "call into" the final projects from the library project? Here is some sample psuedo-code to illustrate my question: Code...

Android :: Common Code For Two Similar Applications?

May 7, 2010

I have a set of common code (including .java files and resources), which I have to use for two similar applications with different package names (for different vendors). How can I maintain two packages which share the common code without making two copies of the common source?

Android :: Load Native Library Which Depends On Third Shared Library

Aug 26, 2009

I created a jni library which depends the third shared library, I must copy the third shared library to /system/lib, otherwise, Java application can't load jni library. But you know, on G1 with official OS image, /system/lib is readonly. I tried to call System.setProperty to set java.library.path to the location stored the thired shared library before load jni library, but the issue still exists.

Android :: Self-contained Test Library Project Cannot Find Library Classes

Aug 17, 2010

According to this SDK guide, unit-testing a Library project can be achieved by creating a standard application project, reference the Library project and then instrument the application for unit testing. However, when I do this and launch the test application I get the message.No tests found with test runner 'JUnit 3".I'm using Eclipse and the Android ADT plugin, all latest versions.the projects compile just fine. The test project also installs fine to the emulator. But in the console I can see that it looks for <library>.apk, which of course doesn't exist since I'm compiling this as a library into the test project.

Android :: Differences Between Jar Library And Library Project

Jul 15, 2010

As I understand, the three ways of distributing my application are via Jar, Android Library and Android Library Project.Jar - cannot contain resources or XML layouts (so this is out for me)Android Library - I don't really know how this works but the Google API uses it..Android Library Project - includes resources but allows the client free rein on the code as it is distributed as source.If I am to create a closed source application that requires drawables and XML files that I want to distribute to other Android programmers, what should I use? And can someone direct me to a tutorial on creating an Android Library?

Android :: Reference Project Library From Another Project

Jun 6, 2010

I have 2 android projects out of which I modified one to work as a library. I want the main project to refer to this library to perform few functions. While this scenario works just as expected, I want to introduce one more functionality. I want to link this library project with another just a java project which has code common to both Android and Blackberry applications. This second part however doesn't seem to work and throws "The application <appname> (<package name>) has stopped unexpectedly. Please try again" with a ForceClose button. I would greatly appreciate if someone can give a brief information on how to make this work.

Android :: R.java File From Android Library Project Not Importing Into Application Project

Aug 8, 2010

I followed the instructions here on how to create an Android library project, and use it in an Android application:

http://developer.android.com/guide/developing/eclipse-adt.html

But it is not working. I can see the library project is added to my application but I cannot reference anything in it because it won't build. The R.java file from the lib is NOT being added to my application project, so the lib project contains tons of errors, everywhere it tries to reference it's own R.java file.

I don't know if this has anything to do with it, but in the console there are messages stating that the there is "No resource identifier found for attribute 'X' in package 'Lib Package'. My library package has a a few styleable attributes defined for a custom view I made, all of which are being complained about in this console message. The library builds just fine, and I don't get those messages in the console until I hook the library to my application, so I don't know what's up with this.

I have an Android library project that makes calls to PreferencesManager.getDefaultSharedPreferences.

I have 2 version of my app, paid/free, and they are not able to access the preferences stored by the library code.

Can someone tell me the right way to store values in SharedPreferences in library code and have the values available to projects that include the library?

Android :: Add Library Project To Project?

Sep 15, 2010

When I right click the project in the eclipse, select "Properties". In the property page, select Android. According to the document, you can add the library project through that page. But my problem is that, there is no library information on the page. It only lists "project build target"

Android :: Shared Library Which Is Not JNI Based

Apr 22, 2010

I am developing a library for Android applications which does not use native code (JNI). I have tried suppling the library as an external jar in my Android projects but this method does not include the library contents in the apk and thus throws class not found errors when run in the emulator or device. I have also tried creating the library as an Android project in itself and this does work, but only for public static properties (not methods). With the library and application both being in separate apk's I can see that the VM notices references to the library and can read some properties, but when an attempt to instantiate a class in the library is executed I get class not found even though I can read the public static properties from it.

I realize that Davlik byte code is not the same as Java byte code but I am having trouble even finding good information about how to solve what would seem to be a very simple issue in Android. I am looking into the old PlatformLibrary stuff right now but I am not convinced this will work either since the sample has been removed from the Android site.

Android :: How Does Two Native Shared Library Communicated?

Mar 20, 2010

I am now writing a java application. On java side I use System.loadLibrary() to load my own native shared library( named a.so ). I want a.so can communicate with another native shared library(named b.so). When a.so and b.so are loaded in the memory, they belonged to 2 different process. I am not familiar with IPC in android and binder mechanism. How can I do to make a.so communicate with b.so?

Android :: Force To Create A Shared Jar Library?

Jul 30, 2009

I have several apps (each in its own apk, process etc) running at the same time on user's device.

these apps are all linked to a single common jar file (internally devloped) which contains a large portion of their overall code size.

is there a way for me to force Android to make this common jar load only once (e.g. into shared memory)?

the reason we want to do it this way, btw, are to reduction of each of the single apps memory intake, on disk footprint and possibly of their startup time.

Android :: Several Activities Sharing Common Code

Jul 2, 2010

I have an Android application composed by several Activities. Most of them need to check whether an active network is available or not:

public boolean isNetworkAvailable() {
ConnectivityManager cm = (ConnectivityManager)
getSystemService(Context.CONNECTIVITY_SERVICE);
TelephonyManager tm = (TelephonyManager)
getSystemService(Context.TELEPHONY_SERVICE);
...
}

I would like to move that code to a helper class in order to avoid the need to write that code in every Activity, but calls to getSystemService are only allowed from an Activity. The other alternative is to move that code to a parent activity use inheritance but:
Every activity already extends from android.app.Activity
Some of my activities already extend from a common my.package.BaseActivity
(Activity <- BaseActivity <- XXXActivity)

What do you recommend in this case? Is there any other alternative?

Android :: Shared Jar Library / Source Branch Under Mydroid?

Aug 3, 2009

we're developing applications that will use a single 'shared library' jar file. the jar file will be packed as part of the operating system (built & packed by us)several trials & errors & manual readings had led us to the conclusion that for our projects (both shared lib & dependent apps) to correctly compiled they must

(a) reside UNDER the mydroid source root and

(b) be compiled with the same java version as mydroid.

both a & b are somewhat inconvenient for us (the latter a bit more). is there a way around them?

Android :: Versioning And Common Code-bases With Eclipse

Sep 14, 2010

I'd like to bring out an Android app in the near future, so I was wondering how to support a couple of funcitonalities I have got used whilstdeveloping for J2ME and iPhone

first the versioning. With J2ME (using NetBeans as IDE) I had the option to auto-increment the softwwares version every time I compiled it. I was wondering if something like this is available for Eclipse and if so how to use it ? secondly a common code base. Is it possible to have a common code base for several projects ? For example I might have a game which actually uses the same code but needs different graphic resources. I'd hate to have a different project for every game/app and have to manually edit every project's source every time I want to submit a new code-change.

Android :: Exporting Project As A Shared Jarfile Under Eclipse

Jun 20, 2009

I've factored out some common code into an Android project, which (certainly under Eclipse) is required to have an AndroidManifest.xml.

If I export this shared code as a jarfile and link it to my main project, the Davik compiler gives an error about a duplicate manifest. If I don't include the mainifest, Davik gives an error that the manifest is missing.

Android :: Simplest Way To Compile An Autotools Based Shared C Library For Droid?

Jul 16, 2010

I have a cross-platform C library that I need to compile for Android as a *.so file. The library consist of many .c and .h files, and it use autotools as it's buid system. (./configure && make dep && make). Afaik, the library does not depend on other libraries, other than libc and OpenSSL (which should be present on Andriod).

I'm trying to find the simplest (read fastest in terms or not needing to read hundreds of pages of manuals and then apply try && fail brute-force approaches to complete the task) way of getting the library off my machine in source code form, and into the Android phones as a .so. The library will eventually be accessed from Java's native library interface. For development, I have both Windows and Debian machines on my desk.
