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.

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?

View 1 Replies View RelatedI have several modules within a single native library, each module is intended to be the compliment to a Java class within the application. How can I call the native functions without having to perform a System. load Library within each Java class? If I load the library in a common class (not through inheritance) the app fails with a link exception.
View 1 Replies View RelatedI 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.
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.
I am taking over a project, and am trying to launch it in the Android Emulator. I get the following error in Logcat:

How can I make sure com.google.android.maps is included in my project?

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?

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.
I need to write a dynamic link library in C++ that is used by Java on Android. As I get, it should be .so library, but I don't know how to do that. I tried Cygwin, but it crashes: Code...

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.

View 3 Replies View RelatedI have developed bluetooth application where native library will be initiated by Java application (using JNI wrapper). JNI will call the entry function of the native library and then it will create Pthread to for scanning the device. Once Scanning is over, i will get the callback which i registered during the entry function of the native lib (called by app). But i haven't received the callback, but if i run the same native library in the shell (executable from the shell terminal) it is working fine. Can any one help me, if there is any specific architecture needs to follow while developing Java application based on native lib?

We have used BlazeDS extensively and we believe that it would nice to provide all the benefits provided by AMF for Android applications as well. We have developed an Android AMF client library which would enable Android application developers use the same extensively. The Android AMF client library supports remoting and secured remoting. This will allow all android applications to use the existing backend like .NET, Java, or PHP. The implementation is asynchronous in nature providing success and failure callbacks. This allows application to perform other tasks without blocking the application. We are currently performing some performance benchmarking and plan to release our library very soon. We would also be incorporating the messaging feature as well.

I'm trying to create a shared lib written in c++. I followed all the steps which are recommended to create the shared lib and to access the native code in Android. But so far I couldn't succeeded in loading the shared lib on device or emulator. When I tried to load the lib by:
static{ System.load("/data/data/com.android/libnative.so");}
Does someone know of a library that is fairly "drop in" and allows you to easily put together multiple authentication options in an Android app to services like Facebook, OpenID, Twitter, etc. much like RPX does?

View 5 Replies View RelatedMy Android application can be divided into a client UI layer and a API layer. i would like to deploy them as separate "applications" so that the API layer can be reused.
In Eclipse, i write them as 2 separate Android projects. In the client UI project, i declare the API project in its build path (Project -> Properies -> Java Build Path -> Projects).
When deploying the client UI project through Eclipse (on my actual G1 phone), it automatically deploys the API project (packaged into APK) as well.
However, when launching the client UI application, i hit this error:
CODE:.............
Looking around, it seems like i should declare uses-library under application in the manifest file for the UI client.
Question is, what should i put under android:name for uses-library? Dev guide says "the name of the library" but what is the name of the library? (i mean, in my API "application", i haven't declared any library name anywhere.)
