Please attach the full logcat. And the android version. |

Hi, Ajay191191 Just Wandering do you have any suggestion for me |
|
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 ? |
|
@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. |
|
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. |
|
@Nagarameshwar I think you are doing it wrong. Follow these steps: |
|
@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. |
|
@Nagarameshwar This is a face recognition app. Forgot to change the readme !! Then, copy your ndk directory path to the field below. You should be able to compile. |
|
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. |
|
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). |

@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 |
|
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. |
|
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 |
|
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. |
|
@Ajay191191 ..Okay I will give a shot ..hope for the best this time...I will let U know the outcome..Thanks a lot |
|
@Nagarameshwar...hey man thanks for conforming...lets try to solve it |
|
@Nagarameshwar ...man I initially post the issue for this problem only.... stuck in the same position |
|

|
