build apk is too large about 100m.how to resize it

I assume you're building it locally?

The opencv libraries (in a directory like OpenCV-android-sdk/sdk/native/libs/arm64-v8a/) are the biggest files in the final apk -- and the only platform we're really supporting is arm64, so the others are wasted space. The other libopencv_java4.so files don't need to be in the apk, which should help a bit.

Beyond that, I'm not sure. 100MB seems excessive, it'd be interesting to see a list of what the largest files are inside it.

(extra trivia: for a while I was trying to statically link opencv to get the apk down into the 5MB range, but never got it working and got distracted by something else...)

thanks. i solve the problem through the following methods.

Android Studio Ladybug Feature Drop | 2024.2.2 OpenCV-android-sdk.4.8.1

splits {
        // Configures multiple APKs based on ABI.
        abi {

            // Enables building multiple APKs per ABI.
            enable true

            // By default all ABIs are included, so use reset() and include to specify that we only
            // want APKs for x86 and x86_64.
            // Resets the list of ABIs that Gradle should create APKs for to none.
            reset()

            // Specifies a list of ABIs that Gradle should create APKs for.
            // include "x86", "x86_64", "arm64-v8a", "armeabi", "armeabi-v7a"
            include "arm64-v8a"

            // Specifies that we do not want to also generate a universal APK that includes all ABIs.
            universalApk false
        }
    }
