How to select the proper version of OpenCV Manager

Since version 1.7 several packages of OpenCV Manager are built. Every package is targeted for some specific hardware platform and includes corresponding OpenCV binaries. So, in most cases OpenCV Manager uses built-in version of OpenCV. Separate package with OpenCV binaries is currently used in a single rare case, when an ARMv7-A processor without NEON support is detected. In this case an additional binary package is used. The new package selection logic in most cases simplifies OpenCV installation on end user devices. In most cases OpenCV Manager may be installed automatically from Google Play.

If Google Play is not available (i.e. on emulator, developer board, etc), you can install it manually using adb tool:

adb install OpenCV-2.4.9-android-sdk/apk/OpenCV_2.4.9_Manager_2.18_<platform>.apk

Use the table below to determine proper OpenCV Manager package for your device:

Hardware Platform Android ver. Package name
armeabi-v7a (ARMv7-A + NEON) >= 2.3 OpenCV_2.4.9_Manager_2.18_armv7a-neon.apk
armeabi-v7a (ARMv7-A + NEON) = 2.2 OpenCV_2.4.9_Manager_2.18_armv7a-neon-android8.apk
armeabi (ARMv5, ARMv6) >= 2.3 OpenCV_2.4.9_Manager_2.18_armeabi.apk
Intel x86 >= 2.3 OpenCV_2.4.9_Manager_2.18_x86.apk
MIPS >= 2.3 OpenCV_2.4.9_Manager_2.18_mips.apk

First application start

There is no OpenCV Manager or OpenCV libraries:


Additional library package installation

There is an OpenCV Manager service, but it does not contain appropriate OpenCV library. If OpenCV library installation has been approved:


If OpenCV library installation has been cancelled:


Regular application start

OpenCV Manager and OpenCV library has been already installed.
