Thank you. No errors now. But when I tried to run the samples, the screen displayed 'camera not supported'. Full details http://answers.opencv.org/question/4500/device-not-found-camera-not-supported/

2012-11-23 06:22:03 -0500 asked a question Device not found. Camera not supported.

Hello again! I tried to run Sample1Java from OpenCV Samples on an emulator. I installed the OpenCV_2.4.3_Manager_2.0_armeabi.apk but my emulator screen displayed 'It seems that your device does not support camera(or it is locked). Application will be closed.' How to resolve this issue? (Setup and error below)

Are you using an emulator? If yes, Tutorial 3 and 4 use OpenCV Native Camera which may not work with emulator.

2012-11-22 11:20:10 -0500 asked a question Errors on importing OpenCV Samples : BasedLoaderCallback cannot be resolved to a type

Hello again! I imported the OpenCV-Android samples in Eclipse. I installed Eclipse,NDK,SDK from here (http://docs.opencv.org/2.4.1/doc/tutorials/introduction/android_binary_package/android_binary_package.html) but got these errors. image description Please I've been struggling for 3 weeks.

2012-11-14 08:23:09 -0500 commented question Error: Cannot run program "\ndk-build.cmd"

I did that already. The only way to compile is through commandline.

2012-11-14 03:42:23 -0500 commented question Error: Cannot run program "\ndk-build.cmd"

@Andrey Pavlenko, I also tried that. Still no effect.

2012-11-14 03:24:16 -0500 commented question Error: Cannot run program "\ndk-build.cmd"

My commandline can detect ndk-build.cmd. I don't know if I correctly compiled the file. Now I want to know what will I do next. Here is my post http://answers.opencv.org/question/4149/opencv-ndk-buildcmd-next-move/?comment=4152#comment-4152

2012-11-14 03:08:25 -0500 commented question Error: Cannot run program "\ndk-build.cmd"

@Kirill Kornyakov Yes. In Properties->C/C++ Build->Environment. NDKROOT=C:\android-ndk-r8b. @Oscanto. I'm using Windows7 so removing .cmd is not needed.

Ok @manmedia. I'll give updates few hours from now. Thanks a lot :D

2012-11-13 17:32:17 -0500 asked a question OpenCV ndk-build.cmd Next move

I think Eclipse doesn't recognize my ndk-build.cmd. So I used windows commandline to build OpenCV Sample-Tutorial 3(Adding Native OpenCV). I wonder if it has errors or is it ready to produce an output. How will I know if it's ready to run? If yes, how will I see the output? What will be my next step? image description

2012-11-13 17:17:17 -0500 commented answer Need help on GCC C++ Linker

Yes man, I followed the manual. No worries about the frustration. I tried using the commandline. I can't post the picture here. So, kindly go to the original link. http://answers.opencv.org/question/4137/error-cannot-run-program-ndk-buildcmd/

2012-11-13 16:32:18 -0500 commented answer Need help on GCC C++ Linker

Yes man, there is. I don't know why Eclipse can't recognize the path to my ndk-build.cmd.

I installed the tools and followed the instructions. But there's a problem in Building application native part from Eclipse (CDT Builder). I've encountered errors on ndk-build.cmd. It's in my directory but Eclipse doesn't recognize it. I really need to proceed. How did you installed your opencv Sir?

2012-11-12 08:38:25 -0500 commented answer Need help on ndk-build.cmd in Android-ndk-r4-crystax

Then what will I use? How did you manage to install your opencv in eclipse? Please.

Please help me install OpenCV4Android on Eclipse.

Here is the link for the OPENCV slides. Some links in the slides (slide 7 link for detailed instruction) gave 404 errors. Do you think it's UPDATED? https://docs.google.com/presentation/d/1EO_1kijgBg_BsjNp2ymk-aarg-0K279_1VZRcPplSuk/present#slide=id.g14d10b04_0_59

2012-11-12 06:24:31 -0500 commented answer Need help on ndk-build.cmd in Android-ndk-r4-crystax

@Andrey Pavlenko. I downloaded the new Android ndk called android-ndk-r8b-windows. I extracted the file to C:\android-ndk-r8b and added it to the PATH (System Properties->Advanced System Settings->Environment Variables) . This gives me the error "C:/android-ndk-r8b/ndk-build.cmd" is not found in PATH". I can see the ndk-build.cmd in the directory but Eclipse didn't detect it.

2012-11-12 06:17:52 -0500 commented answer Where will I locate "android-opencv.mk"?

I tried the new tutorial but it's also old. Can you help me install the new OpenCV4Android? Please. I'm desperate.

Hello, I am very new to OpenCV-Android. I have problems installing OpenCV4Android-SDK. The instruction on http://docs.opencv.org/doc/tutorials/introduction/android_binary_package/O4A_SDK.html says "Install the Manager.apk and the corresponding binary_pack.apk depending on the device CPU..." I don't know the kind of APK to install. I also don't know what does ArmV7A, X86, Armeabi-Armv7A, MIPS mean. Can you help me install the right apk? Here is the screenshot to my available APK located in C:\Work\OpenCV4Android\OpenCV-2.4.3-android-sdk\apk image description

Thank you @Simone. I'll try your answer and come back if I have any problems. Do you have any links for OpenCV4Android installation guide except this http://docs.opencv.org/doc/tutorials/introduction/android_binary_package/O4A_SDK.html ?
