Greatings! I am getting following exception when I try to run demo project on android:

I was builded project as as described here and already checked all similar issues but not successfully. I was running app on lollipop 5.1 API 21 and marshmallow 6.0 API 23 also I tried to push manually that file and added into app/build.gradle this:

splits {
        abi {
            enable true
            reset()
            include 'x86', 'armeabi-v7a'
            universalApk true
        }
    }

But still got error. Os - Parrot Os(based on debian); Cmake version 3.7.2

Also I would like to know how exactly I can build for older devices with API below 23 ?

Regards!

What's your target abi?

[kirilamenski]

@sh1r0 armeabi-v7a

[sh1r0]

Have you build caffe-android-lib with ANDROID_ABI="armeabi-v7a-hard-softfp with NEON"? Currently, only libs for abi x86_64 and arm64-v8a are pre-built and included in this project.

@sh1r0 Sorry for a silly question, how exactly I can do this? I tried to create Application.mk in the folder app/src/main/jni with APP_ABI := armeabi armeabi-v7a x86 x86_64 mips but still get an error

[sh1r0]

@KirilaMenski caffe-android-lib is not integrated in this demo project, please refer to https://github.com/sh1r0/caffe-android-lib#build for building instructions.

@sh1r0 I was alreaddy installed it but still not working. Anyway thanks for the help

[sh1r0]

@KirilaMenski Did you get any errors when building caffe-android-lib?

[kirilamenski]

@sh1r0 Nope it was building perfectly

[sh1r0]

Hi @KirilaMenski, please refer to the latest commit of caffe-android-lib (https://github.com/sh1r0/caffe-android-lib/commit/b9b0ba7deae5e0c298af9ffe78feec1c0567ee91), I've added docker support for building the project.
