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
