The version of OpenCV you get with the apt package is always fairly old. Additionally, there's no guarantee that all the modules (here: the QR decoder) were given the required dependencies (here: quirc). Installing additional packages wouldn't solve this because OpenCV needs them at build time, before packaging.

To get the most recent version, install it via pip:

OpenCV for Android self-compiled library 10x larger than official built

Asked 2021-Mar-23 at 12:28

I try to build the OpenCV 4.5.1 SDK for Android because I need the SDK with contrib modules and the official release [1] only has the standard modules. But the libraries I build are almost 10x larger, for example: libopencv_core.a ==> 47.6 MB self compiled, 5.3 MB from the official repository (both for arm64-v8a)

Here is my cmake command, followed by ninja for compilation.

Install quirc

To build the library and associated demos/tests, type make. If you need to decode "large" image files build with CFLAGS="-DQUIRC_MAX_REGIONS=65534" make instead. Note that this will increase the memory usage, it is discouraged for low resource devices (i.e. embedded). Type make install to install the library, header file and camera demos.
