Installation Failed - Invalid Apk File - Android_opencv_library

I have got a project in eclipse (android_opencv_library) which has the flag 'isLibrary'. In another project 'HelloDepp' I reference this project as a library. There are no errors.

Solution 1:

i think its version problem. first you have check out that your phone version is equal to apk build version or higher

Solution 2:

Copy your apk file you to want install into android-sdk/platform-tools

Then use the command,

cd android-sdk/platform-tools

adb install opencv-manager-x86.apk

This will suitable for any files you want to install
