Hi APT,
We should probably move this discussion to the NDK group, as Dianne suggested. XYZ.so may have an unresolved symbol. One trick we’ve found is using `arm-eabi-objdump xyz.so -t | grep UND` and see if anything you expect to be resolved is actually unresolved. Do you see any output from the linker using strace or from the commandline? That might tell you exactly what’s missing. -Kevin From: android-framework@googlegroups.com [mailto:android-framew...@googlegroups.com] On Behalf Of MMF Sent: Thursday, April 23, 2009 12:31 AM To: android-framework@googlegroups.com Subject: Re: Issues while loading native .so files from JNI Hi All, I have nailed down the problem to xyz.so. When I remove xyz.so from my dependency list I am able to load my jni.so from the App properly. Not sure why this is happening, as I am able to test my jni.so from native test app which is dependent on both abc.so and xyz.so. But when I do the same thing from App the jni.so is not getting loaded. Looks like some problem with my xyz.so. Another observation, if I replace my xyz.so with any other lib (copy some other .so and rename it to xyz.so) I am able to load my jni.so. I will debug it further and let you all know the exact root cause of this issue. ( one wild guess is my xyz.so is having lot of assembly code and this could be one of problems). Thanks a lot for your inputs. Regards APT 2009/4/23 Hsiung, Chuan-Da 熊全達 <cdhsi...@gmail.com> APT, could you try to remove abc.so and xyz.so from the prelink map?

If I am loading a jni.so which is having dependencies on some other .so files then it is giving me an error else it works fine.

I have already mentioned both abc.so and xyz.so as dependencies libs for jni.so. I suppose without mentioning this my jni.so itself would not get generated. But still I get the mentioned error. I think there something more to it than just mentioning the dependencies. Then i guess that missing thing is pushing the jni.so lib to emulator with adb push .. Are u using the Eclipse + Android SDk or u also have the Android Sources Thanks APT On Wed, Apr 22, 2009 at 5:45 PM, Naveen Krishna Ch <naveenkrishna...@gmail.com> wrote: Hi APT/MMF, I have a similar need and i could make it work. abc.so and jni.so in my case. during the android build of jni.so i gave the abc.so as depended shared libray in the Android.mk of jni.

I wish this would help u too 2009/4/22 MMF <android...@gmail.com> Hi All, I am facing a problem while loading .so libs from my App. Here is the story: I have two native libs say abc.so and xyz.so. I have written a JNI component (say jni.so) which is calling APIs from abc.so and xyz.so. Now from the application (Java) when I do system.loadlibrary("jni.so") I get an error as "cannot find library". But when I remove the dependencies of abc.so and xyz.so from jni.so (say I just have some dummy functions in my jni.so) and try to load jni.so from App, it works fine. Can someone please let me know what could be problem?
