Problem with "java.time.Duration" on Applovin adapter

[sergip76]

It is not possible to use the SDK with API lower than 26 due to this problem:

com.applovin.impl.l0.collectGoogleAdvertisingInfo
java.lang.ClassNotFoundException - Didn't find class "java.time.Duration" on path: DexPathList

It seems that the Applovin adapter uses the java.time.Duration class introduced in API 26.

Hi @sergip76,
Thank you for creating the issue.

Unfortunately, this part of the code is not related to the CAS AppLovin Adapter, but rather to the AppLovin SDK, which we cannot modify. However, your issue seems to be related to the Java version. Although Android API 26 introduced the Duration class natively, this class is also available starting from Java 1.8.

Please make sure that your app is using at least Java 1.8. To do so, the following lines should be defined in your app-level build.gradle file:

android {
    // ...
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }

    kotlinOptions {
        jvmTarget = '1.8'
    }
}

Let us know if you managed to resolve the issue.

Yes. I was already using Java 1.8 with the code you wrote. It seems it doesn't solve the problem.
