Compatible side by side NDK version was not found. Default is 20.0.5594570

问题

I am getting the above error

My gradle looks like this

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'

android {
    compileSdkVersion 29
    buildToolsVersion "29.0.3"

    defaultConfig {
        applicationId "com.example.hypersignwalletcorekotlin"
        minSdkVersion 23
        targetSdkVersion 29
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }

}
project.ext {
    walletcore_version = "2.0.5"
}
dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    implementation 'androidx.appcompat:appcompat:1.1.0'
    implementation 'androidx.core:core-ktx:1.2.0'
    implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
    implementation "com.trustwallet:wallet-core:$walletcore_version"
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'androidx.test.ext:junit:1.1.1'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
}

Not able to understand why is this happening.

Thanks

The fix

add ndkVersion to your module's build.gradle

    android.ndkVersion  "your-installed-ndk-version"

as in some examples. You could find your NDK version from file $NDK/source.properties.

Background Info

You probably using AGP/Android Studio version 3.6+: "From Android Gradle Plugin ( AGP ) 3.6+, there is a known good NDK concept added, which is the known good/tested NDK version when that AGP version was released". AGP will use that internal NDK version if:

• you are not using the ndkVersion feature added in AGP 3.5

That internal NDKs are expected to be installed as side-by-side NDK place: $SDK\ndk\ if not installed:

• AGP 3.6, AGP 4.0 will error out
• AGP 4.1 would auto install it.

The internally embedded NDK version, most likely, will be out-of-date pretty quickly as newer NDKs are constantly being released: if you want to use a newer NDK version, you do need to configure gradle with ndkVersion.

Additional Doc

Refer to the ndk-sample's wiki page.
