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.

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 :: 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 :: Include Library Based On API Level Or If Statement?

Aug 17, 2010

So I have a API issue. So i am creating a class that utilizes AndroidHttpClient to download Bitmap images from my server. Problem is, it's API Level is 8 and I want this to be used FROM API 1 and above, now i know i can use DefaultHttpClient (the API is Level 1) but is there a way i can use both, being distinguished by Build.VERSION.SDK (btw thanx for the quick respose, Konstantin Burov and iandisme). So for example, if my device is 2.2 i use AndroidHttpClient, anything else use DefaultHttpClient. Of Course if I import the library it will give me an error on any device 1.5 to 2.1. Any Suggestions would greatly be appreciated, because in the future I would want to set other preferences based on API.

Android :: Shared Library So Size Versus Apk Size

Sep 14, 2010

I would like to know why the size of my shared library .so is bigger than my .apk file generated with Eclipse? Approximatly the so size is twice the apk one. What is strange is after having installed it in the device (2.1 firmware) I checked the size of the apk when I uninstalled it from the device and surprisingly the apk size indicated is bigger even than the .so one. Is there any explaination of that?

Android :: How To Compile All Source Files - Default Make Target Does Not Compile All Of Them

Mar 16, 2010

when I compile android (http://source.android.com/download) it does not compile some source files. For example there is external/bluetooth/bluez/sbc/sbc.c which is not compiled. There are also other such files.

It's possible those files need not to be compiled. Or it might be that I need some special configuration to compile them.

Either way, if it is possible, I'd like to compile them. Is there some way to do it? Maybe some "compile_all" make target? (I believe the reason why I want to compile all source files is not important)

Android :: Simplest Way To Draw Pixels Lines / Circles On A View?

Aug 14, 2010

What is the simplest way to draw pixels, lines and circles on a View?I want to move a cross cursor around, so nothing particularly intensive.I thought I could extend SurfaceView and add it to an XML and it would just work, but it just appears black, however, when I look at the layout view of localmap.xml in eclipse, the graphics appear as expected. Any ideas? My onDraw is never called on the emulator, and even calling invalidate on the class makes no difference. I shall keep trying but can anyone see anything I've missed? or is there a better way entirely? Code...

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.

HTC EVO 4G :: Stock 2.2 - Simplest And Easiest Way To Root?

Sep 24, 2010

I'm looking for advice on the simplest and easiest way to root. I know theres something that wipes the phone, rolls back to 2.1 and then roots it. I just got my second eEo because my first overheats. It came with 2.2, is that an issue? What do I need to know about ROMs? I hear fresh evo is a good one. I don't mind losing all the sprint stuff as well as HTC. I prefer launcher pro so any widget loss doesn't bother me. I heard about the method to rollback 2.2, root it then whatever, but everywhere I found today from that day says that a simpler method should be out in a couple weeks. It has been a month, is there a simple point and click method yet?

HTC EVO 4G :: Simplest Way To Transfer Contacts From Blackberry To Phone?

Jun 12, 2010

Basically topic. I know the simplest way to do it would have been to Google Sync my contacts into my Gmail from my BB then sync them to the EVO, but unfortunately, I can't do that now. The SIM in my BB is out thanks to my number transfer so no data, and I didn't have Google Sync installed.

I have a little over 200 contacts in my BB, and as I'm sure you understand putting all of them in manually is near insanity. Anyone in the same boat as me? Any solutions to this or is a long night of manual contact switching in my future?

Samsung Captivate :: Simplest Way To Side Load Apps

Jul 21, 2010

I don't know if this was already posted and I am sorry if it was, but I would just like to show people how to sideload apps NOT using root and in very simple words.

1. Download Droid Explorer for your system. (de - Release: Droid Explorer 0.8.7.0 Beta)

2. Now, go to your phone. Settings> Applications> Development > USB Debugging.

3. Make sure you downloaded the drivers for the captivate then plug in your phone and select PC connect and mount the phone.

4. Now open Droid Explorer and connect the device. Right click and select batch install.

5. Now a screen should pop up and you should select the APKs you would like to install and it is self explanatory from there on out.

That should do it, sorry if this was posted somewhere else or something but I kind of figured this out on my own even though I am not a very techy guy.

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?
