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");}

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 12 Replies View RelatedI 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 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.

View 2 Replies View RelatedMy wife and I both have Android phones (EVO and Samsung Transform) and have the Google Calendars shared. All of the sudden, her calendar is completely empty and can't see mine anymore.But on mine, I still see all of her events and see it listed as one of my Calendars both in Google Calendars and on my phone.Everything looks perfect on my end but everything is back to square one on hers.Any ideas how to restore her calendar or what may have caused it.I am afraid that just starting hers over is going to start duplicating events in mine.

View 1 Replies View RelatedI am trying to have 2 applications which can access each other's data.I have a two test applications which I am experimenting with.I set the 'Shared user id' for each to 'com.gabysoft.sharedfiles'.However, when I sign the first app and try and install it, I get the error:
11-05 16:50:33.422: ERROR/PackageManager(61): Package com.gabysoft.sharedfiles1 has no signatures that match those in shared user com.gabysoft.sharedfiles; ignoring!
Clearly, I am not signing it correctly (I am using Eclipse's "Export signed application package" function).How do I properly sign the .apk file so that I don't have this problem?
We are investigating the possibilities to package & deploy platform UI extensions which can contain both Java code and resources - which then can be (re-)used by applications using <uses-library> tag in the AndroidManifest.xml. One solution which has been discussed was to use the aapt -x option together with the new --custom-package option introduced in November to generate unique resource identifiers for the shared resource package. Then, just as the <uses-library> information in the manifest file would bootstrap the class loader with the listed extension packages, it would add these packages to the asset manager as well - allowing the asset manager to locate and load the extension resources. (This would require a platform extension.)If this is a way forward - using the 8 package bits in the resource identifiers? This solution would probably work initially for one vendor since the allocation of unique package identifiers would be an internal issue, but if extension packages where to be exchanged within the android community there would be a high risk of packages using the same identifiers.

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.
Im wondering if there is an app or anyway to set a shared folder on the Evo's SD card that can be seen over wifi to drop files in? I have dropbox and IO Filemanager but that's a lot of clicking to move stuff out of the dropbox. I was hoping someone knew of an app that would setup a share over wifi.

View 2 Replies View RelatedI would need to export the shared preferences and load it on another device. Is this possible in a direct way somehow? (without exporting the keys one by one and writing to a custom file) Another question is that there is any XML parser which has the same functionality like SharedPreferences (getstring/addstring, getint/ addaddint etc.) and saves/loads the result to a path anywhere? (sdcard for example) I know SharedPreferences uses some xml's in the background but that xml is not readable as a file without admin rights as far as I know so it's not quite suitable for what I need.
