Hi, Ajay191191 Just Wandering do you have any suggestion for me

[Ajay191191]

I am sorry, I did not get time to corner the cause of this error. Can you try to install from scratch and also tell me if you find a solution for this ?

[Ajay191191]

@Nagarameshwar I think your error is related to jni library not getting loaded,i.e the libnative_sample.so. Make sure that you have not deleted the static loading or you are correctly loading it.

[sayandev]

Nagarameshwar I think it would be easier for U to debugg the problem if U go through some sample of Native Android and OpenCV android simple application. here are the links: http://developer.android.com/training/articles/perf-jni.html http://blog.edwards-research.com/2012/04/tutorial-android-jni/ http://opencv.org/platforms/android.html

[Ajay191191]

@Nagarameshwar I think you are doing it wrong. Follow these steps: Download the android-ndk and the opencv "android" sdk. Put the ndk build path in your project properties, and the dependent sdk in the library. Compile and run.

[sayandev]

@Ajay191191 ..one quick question its not related to the issue this app is of Face recognition or detection as the name revealed is Face recognition but tin the read me file U wrote "This is an Android application for Face Detection using the OPENCV API." A quick reply will be highly appreciated.

[Ajay191191]

@Nagarameshwar This is a face recognition app. Forgot to change the readme !! And u dont have to select the libstdc version, ndk will select the version according to your android version. So this could mean you are not importing it right. OK do one thing. Make sure you have the android opencv sdk project imported in eclipse. Then make sure the opencv sdk library is selected according to the image below.

Then, copy your ndk directory path to the field below. You should be able to compile.

[Ajay191191]

As you can see, there is an error importing the opencv android sdk, first rectify that. And try to run the samples from the sdk first.

[Ajay191191]

http://docs.opencv.org/doc/tutorials/introduction/android_binary_package/O4A_SDK.html

Follow this.

[Ajay191191]

http://opencv.willowgarage.com/documentation/cpp/basic_structures.html#mat

It has rows and cols as members, and also doesn't have any other methods to get the same. So I still think there is something missing in your configuration, as they are the class members(hoping you haven't changed the "images" vector type).

[sayandev]

@Ajay191191 ..Hi, was wandering have u got a chance to verify the issue I was facing, i.e. In Log cat its showing native_takePicture failed...when I was pressing the capture button in the welcome page...At least if U could give me the info what android version (target) U have used and what hardware device (Android OS version) U have used to run it..I will try to simulate in same environment..thanks in advance

[Ajay191191]

I had tested it on an ARMV6 board on both 2.3.3 as well as 4.1.2 until it recently died . And AFAIR it had happened to me once, but was due to my camera libraries. Nothing to do with the app though.

[sayandev]

Dear @Ajay191191 ...I really appreciate your quick response...Could U please elaborate the problem due to "camera libraries"..I mean any link where the problem and the way to solve been discussed ..I guess I am yet to check the possibility...Thanks again

[Ajay191191]

By camera libraries I mean the proprietary device library files (.so files). I had that problem since I was running a custom rom, and I was using the wring camera library files.

[sayandev]

@Ajay191191 ..Okay I will give a shot ..hope for the best this time...I will let U know the outcome..Thanks a lot

[sayandev]

@Nagarameshwar...hey man thanks for conforming...lets try to solve it

[sayandev]

@Nagarameshwar ...man I initially post the issue for this problem only.... stuck in the same position

[sayandev]

@Nagarameshwar ... R u able to view the picture preview...I mean in the main form, after pressing the Take Picture Button for me a black screen is appearing no camera preview, with Exit, Capture and Cancel..what about U?

[sayandev]

Sounds good for me I'm not having any preview have U change any came handling parameter in the code..

[sayandev]

how do u find which header files are unresolved in logcat there is no clue...could U pls explain the way U take care of this issue..

[sayandev]

@Nagarameshwar .. Man I am not able to find the index option after right clicking on my project. Second of all I tried to buil it for armeabi; armeabi-v7a x86 both using the command APP_ABI := armeabi armeabi-v7a x86 in application.mk still it didnt work

[sayandev]

armeabi; armeabi-v7a and x86; none works

[sayandev]

neel.hit@gmail.com

[sayandev]

I tried on my tab Asus Transfoer prime tab

[Ajay191191]

@Nagarameshwar , try using APP_ABI := armeabi armeabi-v7a LOCAL_ARM_NEON := true

[kumaranoop]

@ajay i have download ur project when i am running it it is show error "open cv manager has stopped" any solution please tell me

[Marchello89]

@Ajay191191 i have the same problem that @Nagarameshwar had, the application crash and told me: "Unfortunately ocv t3 addnative opencv have stopped. How can i resolve it? Thank you very much

[arjunharish]

I'm getting such an error can u help me??? "C:\Work\OpenCV4Android\android-ndk-r8d\ndk-build.cmd" Install : libnative_sample.so => libs/armeabi/libnative_sample.so

[amiraelsayed]

I have this issue when I try to run this application, after I take the picture and press detect face the application crash, if you can please help me as I'm new in computer vision field and I need to make face recognition with android

Thanks

[Matt342]

dear @Ajay191191 Can you see me how to make this project from the beginning? please... in the form of video, for more details contact me.. aganmatz@gmail.com
