Hello getting the error above. Thank you

@sanribadu I believe this is a duplicate of #1. Also please post the full error log.

And i am not sure if this is correct: setting the path of the openc cv and the eigen

@sanribadu you are using OpenCV 2.4.9 Please update to 3.1.0: https://github.com/opencv/opencv/releases/download/3.1.0/OpenCV-3.1.0-android-sdk.zip.

[sanribadu]

Updated to 3.1.0 and the still getting the "executing external native build for ndkBuild .. Error :"

Could it be because i did not use the set environment variable approach?

[Lauszus]

Have you installed Android NDK for Android studio? Can you see the full Gradle log somewhere, so I can see the full error message?

Btw I reopened the issue, as I believe you closed it by accident?

[sanribadu]

yes installed the android NDk... and here is the log:

[Lauszus]

You haven't checked out the submodule. Please run:

git submodule update --init --recursive

Also please check out the updates build instructions, so you can set the environmental variables instead of hardcoding the path: https://github.com/Lauszus/FaceRecognitionApp#build-instructions.

[Lauszus]

@sanribadu any updates?

[sanribadu]

sorry for the late reply been off for a while. Its not giving any error but the keeps saying that "E/JavaCameraView: Front camera not found!"

[Lauszus]

What device are you using?

Try to replace this line: https://github.com/Lauszus/FaceRecognitionApp/blob/master/app/src/main/java/com/lauszus/facerecognitionapp/FaceRecognitionAppActivity.java#L369 with:

mOpenCvCameraView.setCameraIndex(prefs.getInt("mCameraIndex", CameraBridgeViewBase.CAMERA_ID_ANY));

[sanribadu]

Thank you for the application, it is working fine now.

[Lauszus]

You're welcome :)

[Lauszus]

@sanribadu what device are you using? I guess there is no front camera on it?

git submodule update --init --recursive inwindows

Sorry to bother you. I'm working on windows. I have install the Git and add it to the environment variable. But when I run the command ,"git submodule update --init --recursive", in cmd, there are something wrong.

$ git submodule update --init --recursive
fatal: E:/Program Files (x86)/Git/mingw64/libexec/git-core\git-submodule cannot be used without a working tree.'

sir i still didnt understand how the applicatin will recognize faces
Can you kindly help me with that?
