Android App running fine in Emulator but can't install in real device

Question

I'm developing an android application for simple Facial recognition. My Application build and run fine in emulator but get Cmake Error when try to install in real device. Error Message:

Task :engine:configureCMakeDebug[arm64-v8a] FAILED Execution failed for task ':engine:configureCMakeDebug[arm64-v8a]'. [CXX1410] D:\KAM\code\AET\AET\engine.cxx\Debug\3p465u2i\arm64-v8a\android_gradle_build.json debug|arm64-v8a : expected buildTargetsCommandComponents or ncnn-release-arm64-v8a.buildCommandComponents to exist

I try to find the reason but no luck. So far find only [this][1].
Any help or resource will be great for me. Thanks

Answer 1

first rebuild your app and then check this location

PROJECT PATH...\app\build\intermediates\cmake\debug\obj

There should be at least 4 folders for different abi's

x86 - x64 -- arm64/v7a -- arm64/v8

if its not exist there

apply this to your build.gradle

abiFilters 'x86', 'x86_64', 'armeabi', 'armeabi-v7a', 'arm64-v8a'
