Gradle native libraries not found on device but present in apk

Question

My application uses Here SDK and Twilio SDK. Both uses native libraries (Here SDK with native libraries locally plugged in from /libs and /jniLibs folders, Twilio SDK plugge

Answer 1

By defining a splits block you can tell Gradle to create APKs for each listed ABI:

include "armeabi", "armeabi-v7a", "x86", "mips"

Alternatively you can include all desired ABIs into one APK by adding the following filter:

android {
(...)
defaultConfig {
    (...)
    ndk {
        // allow only 32bit *.so libs
        abiFilters "armeabi", "armeabi-v7a", "x86", "mips"
    }
}

}

Both approaches will exclude 64bit functionality that might clash with the 32bit HERE SDK, but the latter will support more devices with a single APK.

Some libraries, like the new Android Room Persistence library, add 32bit flavors along with the two 64bit ABI flavors arm64-v8a and x86_64. Since HERE SDK at the moment only provides a 32bit lib it should be safe to exclude 64bit lib variants. On the other hand it is expected that 64bit devices can gracefully handle 32bit libs.
