Answer 1

This helped me. Sharing it for someone who might come up with same issue.

android {
    ....
    defaultConfig {
        ....
        ndk {
            abiFilters "armeabi", "armeabi-v7a", "x86", "mips"
        }
    }
}

Answer 2

-if gradle.properties not available then first add that file and add android.useDeprecatedNdk=true

-use this code in build.gradle

defaultConfig {
    applicationId 'com.example.application'
    minSdkVersion 16
    targetSdkVersion 21
    versionCode 11
    versionName "1.1"
    ndk {
        abiFilters "armeabi"
    }
}

Some old gradle tools cannot copy .so files into build folder by somehow, manually copying these files into build folder as below can solve the problem:

build/intermediates/rs/{build config}/{support architecture}/

build config: beta/production/sit/uat

support architecture: armeabi/armeabi-v7a/mips/x86

Answer 4

Yet another crash cause and possible solution is described in this article: https://medium.com/keepsafe-engineering/the-perils-of-loading-native-libraries-on-android-befa49dce2db

Briefly:
in build.gradle

dependencies {
    implementation 'com.getkeepsafe.relinker:relinker:1.2.3'
}

in code

static {
    try {
        System.loadLibrary("<your_libs_name>");
    } catch (UnsatisfiedLinkError e) {
        ReLinker.loadLibrary(context, "<your_libs_name>");
    }
}

Answer 5

In my case After running the ndk-build in the jni folder the shared library was created under the libs folder but the path specified in build.gradle

sourceSets.main {
        jni.srcDirs = []
        jniLibs.srcDir 'src/main/jniLibs'
    }

so I need to move the created shared library to jnilibs folder and it worked!

If you are using Android studio, just edit the gradle.properties in the root folder and add android.useDeprecatedNdk=true. Then edit the build.gradle file in your app's folder, set abiFilters as below:

android {
....
defaultConfig {
    ....
    ndk {
        abiFilters "armeabi", "armeabi-v7a", "x86", "mips"
    }
}
}
