Hi Dianne, Thank you for your help with this.
I'm trying to implement the shared library so that hopefully if we ever need to use this, the Market will support that kind of filtering by that time. Also, since we report to our servers an ID unique to carrier/oem/handset, we want to carry this information in this shared library so that a generic update can pick up the handset-specific information. I'm having a problem getting <uses-library> to work, though (see problem description below) On Dec 18 2009, 1:42 pm, Dianne Hackborn <[email protected]> wrote: > Actually, if your app needs some functionality from the device that is not > part of the platform, the proper way to do this is to put it in a shared > library like this that the application uses (and the OEM implements).

Our application doesn't actually need anything specific provided by the OEM for the app to run, but our app provides a service and content provider that the OEM then uses to obtain information. Since this integration is a key element of our product, it doesn't make sense to put it on a handset that doesn't have the OEM-level support. So I've created a project with a single class "com.cequint.platform.CequintConfig". I've run dx on the resulting class files and packaged it in to a JAR file with a MANIFEST.MF similar to that in other .jar files I see in /system/framework. Indeed, I just copied the MANIFEST.MF from monkey.jar. So my jar file is named com.cequint.platform.jar and contains: /META-INF/MANIFEST.MF /classes.dex This jar file layout is the same for monkey.jar and com.google.android.maps.jar. I then remounted /system on an OEM development phone and pushed com.cequint.platform.jar into the /system/framework directory. I added <uses-library android:name="com.cequint.platform" /> to a test application's <application> section. When I try to install the test application, I get an error from "adb install": Failure [INSTALL_FAILED_MISSING_SHARED_LIBRARY] What am I missing here?
